Bay, was mapped during May to October 1992 at a scale of 1:24,000 using black and white aerial photography. SAV bed perimeter information was digitized and stored in a computerized data base. Ground truth information was obtained from the U. S. Fish and Wildlife Service; the University of Maryland Horn Point Environmental Laboratories; Harford Community College, Maryland; Essex Community College SAV Research Group of Baltimore County, Maryland; Maryland-National Capital Parks and Planning Commission, Patuxent River Park; and the College of William and Mary, School of Marine Science, Virginia Institute of Marine Science. Citizen support via the U. S. Fish and Wildlife Service and the Chesapeake Bay Foundation provided additional ground truth information. In 1992, the Chesapeake Bay had 28,591 hectares of SAV, compared to 25,623 hectares in 1991, with 2,516 hectares (8.7%), 13,713 hectares (48.0%), and 12,362 hectares (43.2%) occurring in the Upper, Middle, and Lower Bay zones, respectively (Figs. 1, 2, and 3). SAV increased in most sections in 1992 with the largest increases in SAV abundance occurring in the Eastern Bay and Choptank River sections. SAV declined in only a few sections, notably the Upper Potomac River section. In 1992 in the Upper Bay zone, 71.2% (1,792 hectares) of SAV was located in the Susquehanna Flats (Section 1). Overall abundance of SAV increased from the 1991.1evel (1,684 hectares), while the density of the beds in 1992 increased slightly from 1991. In the flats, 88.6% of all SAV beds were classified as very sparse in 1992 (0-10% coverage) (Figure 3), the same as in 1991, but 8.0% of beds were classified as dense in 1992 (70-100% coverage), an increase of 1.0% compared to 1991. Myriophyllum spicatum, Heteranthera dubia, Vallisneria americana, Hydrilla verticillata, and Ceratophyllum demersum were among the six species reported from many of the SAV beds. In the Upper Eastern Shore (Section 2) there were 283 hectares of SAV in 1992 (43 hectares less than in 1991), located principally in the Elk and lower Sassafras rivers, and in Swan, Stillpond, and Chum creeks with M. spicatum and V. americana found most frequently, especially in the Elk River. The Upper Western Shore (Section 3) had 186 hectares of SAV concentrated in Saltpeter, Seneca, and Dundee creeks, compared to 91 hectares recorded in 1991. Myriophyllum spicatum, Elodea canadensis, and C. demersum were frequently cited. In the Chester River (Section 4) SAV abundance (255 hectares) was up 198 hectares from 1991. SAV was most abundant adjacent to Eastern Neck, Eastern Neck Island, and in Gray's Creek in the lower Chester River. Ruppia maritima was most commonly cited. In 1992,43.7% (5,994 hectares) of the SAV in the Middle Bay zone was found in the Mid-Bay Island Complex (Section 13), which includes the broad shoal area between Smith and Tangier Islands. This is an increase of 287 hectares over 1991. In this zone, 22.2% (3,047 hectares) of SAV was present in the Middle Eastern Shore (Section 12), primarily in the Barren Island-Honga River area, the Big and Little Annemessex rivers, and the lower section of the Manokin River, with R. maritima reported most frequently.

(Refer to Figure 7, Table 3, and Appendix B for section locations and boundaries.) xii Western Shore (Section 5), Patuxent River (Section 8), and Middle Western Shore (Section 9). Citizens' surveys reported Zannichellia palustris at numerous locations in the South and Severn rivers, while 12 species were reported from the small marsh creeks in the upper Patuxent River. The Middle Bay zone also includes the entire Potomac River, where 3,033 hectares of SAV were present in 1992. SAV was concentrated in two distinct regions: 1) the Upper Potomac River (Section 11) with 2,462 hectares; and 2) the upper portion of the Lower Potomac River (Section 10) with 571 hectares, including Nanjemoy Creek and Port Tobacco River. The total abundance of SAV in the Upper Potomac section decreased by 554 hectares from 1991. Declines in SAV were most notable in the Alexandria, Mt. Vernon, and Fort Belvoir quadrangles, primarily in the mainstern river, the southern edge of the large bed at the Woodrow Wilson Bridge, and in Piscataway Creek. Ground survey data were limited in this section in 1992 to only Citizens' surveys with five species reported: M. spicatum, V. americana, H. verticillata, Najas guadalitpensis and C. demersum. SAV increased in the Eastern Bay and Choptank River sections for the first time since the late 1980's. SAV in the Eastern Bay (Section 6) increased 486 hectares from 1991 to a total of 554 hectares in 1992. In the Choptank River (Section 7) it increased 971 hectares from 1991 to a total of 1,085 hectares in 1992. Most of the increase in the Eastern Bay occurred in the Miles River, while in the Choptank River section SAV beds were most abundant in Harris and Broad creeks and in Trippe Bay. Three species were reported from Sections 6 and 7, with R. maritima most commonly cited. In 1992, distribution and abundance of SAV in the Lower Bay zone were similar to 1991. In this zone, 47.9% (5,920 hectares) of the SAV was found in the Lower Eastern Shore (Section 14) around the Fox Islands and the mouths of major creeks (i.e. Cherrystone Inlet and Hungars, Mattawoman, Occahannock, Craddock, Pungoteague, and Onancock creeks). Along the western shore of the Chesapeake Bay, SAV was abundant in Mobjack Bay (Section 18) (14.7% of SAV in the Lower Bay zone), in the lower York River (Section 19) (6.7% of SAV in the Lower Bay zone), and in the Lower Western Shore (Section 20), specifically Back River and the Drum Island Flats area adjacent to Plum Tree Island (16.4% of SAV in the Lower Bay zone). There were 778 hectares of SAV mapped in the Reedville Region (Section 15) in 1992, a 22.5% increase over 1991. There were 396 hectares of SAV identified in 1992 in the New Point Comfort Region (Section 17) compared to 339 hectares in 1991. SAV abundance was up 15.3% from 1991 in both the Piankatank and Rappahannock rivers (Section 16). The James River (Section 21) had less than 4 hectares of SAV in 1992. Zostera marina and R. maritinia were the abundant species in this zone. SAV in the Chincoteague Bay section increased in distribution with 3,324 hectares mapped in 1992 compared to 2,746 hectares in 1991. Most of the SAV in Chincoteague and Sinepuxent bays, which consisted of Z. marina and R. maritima, was located along the eastern side of the bay behind Assateague Island. Some small beds, consisting of R. maritima, were located along the western side of Isle of Wight and Assawoman bays. xiii ACKNOWLEDGEMENTS We would like to gratefully acknowledge all federal and state agencies who financially supported this project: the U.

Although these other algae do constitute a portion of the SAV biomass in the Chesapeake Bay and tributaries (Humm, 1979), this study has not attempted to identify, delineate, or discuss the algal component of the vegetation nor its relative importance in the flora, except for the Characeae. This is the case, for example, with the benthic marine algae, including many macrophytes, which sometimes co-occur in the same beds as vascular plants, even as epiphytes on vascular plants. Ten species of submerged aquatic vegetation are commonly found in the Chesapeake Bay and its tributaries. Zostera marina (eelgrass) is dominant in the lower reaches of the bay. Myriophyllum spicatum (Eurasian watermilfoil), Potamogeton pectinatus (sago pondweed), Potamogeton perfoliatus (redhead grass), Zannichellia palustris (homed pondweed), Vallisneria americana (wild celery), Elodea canadensis (common elodea), Ceratophyllum demersum (coontail), and Najas giiadalupensis (southern naiad) are less tolerant of high salinities and are found in the middle and upper reaches of the bay (Stevenson and Confer, 1978; Orth et al., 1979; Orth and Moore, 1981, 1983). Ruppia maritima (widgeon grass) is tolerant of a wide range of salinities and is found from the bay mouth to the Susquehanna Flats. Approximately twelve other species are only occasionally found and, when present, occur primarily in the middle and upper reaches of the bay and the tidal rivers (Appendix A). Hydrilla verticillata (hydrilla), a recently introduced species, presently dominates SAV beds in the tidal freshwater reaches of the Potomac River. It has also been reported again in 1992 in the Susquehanna Flats where its growth has not been as widespread as in the Potomac River (Kollar, pers. comm.). Zostera marina and R. maritima are the dominant species reported from Chincoteague Bay. SA V METHODS INTRODUCTION Black and white aerial photography at a scale of 1:24,000 was the principal source of information used to assess distribution and abundance of SAV in the Chesapeake Bay, its tributaries, and Chincoteague Bay in 1992. There were 1,514 photographs from 141 flight lines which were carefully examined to identify all SAV beds. Outlines of SAV beds were subsequently drawn onto USGS 7.5 minute quadrangles and then digitized, which provided a digital data base for analysis of bed areas and locations. Ground survey information collected in 1992 was tabulated, placed onto the same 7.5 minute quadrangles, and entered into the SAV digital data base. AERIAL PHOTOGRAPHY The 1992 SAV aerial photography was obtained by Air Photographics (Martinsburg, West Virginia) using a Wild RC-20 camera with a 153 mm (6 inch) focal length Aviogon lens and Agfa Pan 200 film. The camera was mounted in the bottom fuselage of Air Photographics' Piper Aztec, a twin engine reconnaissance aircraft. Photography was acquired at an altitude of approximately 12,000 feet, which yielded 1:24,000 scale photographics. Flight lines to obtain the photography were predetermined by Air Photographics to include all areas known to have SAV, as well as those areas which could potentially have SAV (i.e. all areas where water depths were less than 2 m at mean low water). There were 141 flight lines covering 1,785 miles of shoreline and yielding 1,514 exposures. Flight lines included land features that were necessary to establish control points for accurate mapping (Figure 4). Sections of the upper Rappahannock, upper York, and most of the James rivers were not photographed for analysis because of prior determination of the continued absence of SAV in these areas. Flight lines were prioritized by sections. Flights were timed to occur during the peak growing season of species known to occur in the sections. In addition, specific areas with significant SAV coverage were given priority. Dates of photography for each quadrangle are noted on each map in Appendix C. General guidelines followed during acquisition of aerial photography (Table 1) address tidal stage, plant growth, sun elevation, water and atmospheric transparency, turbidity, wind, sensor operation, and plotting. Adherence to these guidelines assured acquisition of photography under nearly optimal conditions for detection of SAV, thus insuring accurate photointerpretation. Deviation from any of these guidelines required prior approval by VIMS staff. Quality assurance and calibration procedures were consistently followed. The altimeter was calibrated annually by the Federal Aviation Administration. Camera settings were selected by automatic exposure control. Sun angle 2 43 SUSQUEHANNA R.

Tidal Stage - Photography was acquired at low tide, +/- 0-1.5 ft., as predicted by the National Ocean Survey tables. 2. Plant Growth - Imagery was acquired when growth stages ensured maximum delineation of SAV, and when phenologic stage overlap was greatest. 3. Sun Angle - Photography was acquired when surface reflection from sun glint did not cover more than 30 percent of frame. Sun angle was generally between 200 and 400 to minimize water surface glitter. At least 60 percent line overlap and 20 percent side lap was used to minimize image degradation due to sun glint. 4. Turbidity - Photography was acquired when clarity of water ensured complete delineation of grass beds. This was visually determined from the airplane to insure that SAV could be seen by the observer. 5. Wind - Photography was acquired during periods of no or low wind. Off-shore winds were preferred over on-shore winds when wind conditions could not be avoided. 6. Atmospherics - Photography was acquired during periods of no or low haze and/or clouds below aircraft. There could be no more than scattered or thin broken clouds, or thin overcast above aircraft, to ensure maximum SAV to bottom contrast. 7. Sensor Operation - Photography was acquired in the vertical mode with less than 5 degrees tilt. Scale/altitude/ film/ focal length combination pen-nitted resolution and identification of one square meter area of SAV (at the surface). 8. Plotting - Each flight line included sufficient identifiable land area to assure accurate plotting of grass beds. 4 1992 was measured with a sensor on the plane. Flight lines were plotted on 1:250,000 scale maps to allow for overlap of photography. To minimize image degradation due to sun glint, the camera was equipped with a computer controlled intervalometer which established 60% line overlap and 20% sidelap. An automatic bubble level held the camera to within one degree tilt. The scale/ altitude/ film/focal length combination was coordinated so that SAV patches of one square meter could be resolved. Wind speed was monitored hourly. Under normal operating conditions, flights were usually conducted under wind speeds less than 10 mph. (Above this speed, wind-generated waves stir bottom sediments which can easily obscure SAV beds in less than one hour). The pilot used experiential knowledge to determine what acceptable level of turbidity would allow complete delineation of SAV beds. During optimum flight conditions the pilot was able to distinguish bottom features such as SAV or algae at low tide. Excessively turbid conditions precluded photography. Determination of optimum cloud cover level was based on pilot experience. Records of this parameter were kept in a flight notebook. Every attempt was made to acquire photographs when there was no cloud cover below 12,000 feet. Cloud cover did not exceed 5% of the area covered by the camera frame. A thin haze layer above 12,000 feet was generally acceptable. Experience with the Chesapeake Bay has shown that optimal atmospheric conditions generally occur two to three days following passage of a cold front, when winds have shifted from north-northwest to south and have moderated to less than 10 mph. Within the guidelines given for prioritizing and executing the photography, the flights were planned to coincide with these atmospheric conditions where possible. All film was processed by Air Photographics. A 9 inch x 9 inch black and white contact print was produced for each exposed frame. Each photograph was labeled with the date of acquisition as well as flight line number. Film and photographs were stored under appropriate environmental conditions to prevent degradation. MAPPING PROCESS For this analysis USGS 7.5 minute quadrangle maps were utilized for mapping SAV beds from aerial photography, for digitizing the SAV beds, and for compiling SAV bed area measurements. Figure 5 gives locations of 179 quadrangles in the study area which includes all regions with potential for SAV growth. Most quadrangles are sequentially numbered for efficient access to data. The name corresponding to each quadrangle in Figure 5 is listed in Table 2. Identification and delineation of SAV beds by photointerpretation utilized all available information including: knowledge of aquatic grass signatures on film, distribution of SAV in 1992 from aerial photography, 1992 ground truth information, and aerial site surveys. USGS 7.5 minute quadrangle maps (1:24,000 scale) printed by the Mid-Continent Mapping Center of the National Cartographic Information Center on stable transparent mylar were used as base maps. Distortion-free, identical copies of these base maps were made at the same scale on stable transparent mylar using a contact diazo process. 5 QUEHANNA R.

Savedge,Va. 8 1992 SAV beds from the 1992 aerial photographs were then mapped onto these diazo mylar copies of USGS 7.5 minute quadrangles. Delineation of each SAV bed was facilitated by superimposing the photographic print with the appropriate diazo mylar quadrangle on a light table. SAV bed boundaries were then traced directly onto the diazo mylar quadrangle with a pencil. Where minor scale differences were evident between a photograph and a quadrangle, or where significant shoreline erosion or accretion had occurred since USGS publication of a map, either a best fit was obtained or shoreline changes were noted on the quadrangle. In addition to delineating SAV bed boundaries, an estimate of SAV density within each bed was made by visually comparing each bed to an enlarged Crown Density Scale similar to those developed for estimating forest tree crown cover from aerial photography (Fig. 6, p. 13). Bed density was categorized into one of four classes based on a subjective comparison with the density scale. These were. 1, very sparse (<10% coverage); 2, sparse (10-40%); 3, moderate (40-70%); or 4, dense (70-100%). Either the entire bed or subsections within the bed were assigned a bed density number (1 to 4) corresponding to the above density classes. Some beds were subsectioned to delineate where variations in SAV density occurred. Additionally, each distinct SAV unit (bed or bed subsection) was assigned an identifying two letter designation unique to its map. Subsections were futher identified as contiguous beds by the addition of two letters unique to that sequence. These contiguous bed identifications aid the tracking and analysis of single natural bed units that were subsectioned due to variation in SAV density. Coupled with the appropriate SAV map number and year of photography, these two letter designations uniquely identify each SAV bed in the data base. SAV PERIMETER DIGITIZATION The perimeters of all SAV beds mapped from the aerial photography onto the diazo mylar copies were digitized in a clockwise direction using a NUMONICS Model 2400/2200 DigiTablet Graphics Analysis System with a resolution of .001 inches (.00254 cm) and an accuracy of .005 inches (.0127 cm). All coordinates were transmitted to a PRIME 9955 computer for data management and analysis via software developed at VIMS. The perimeter of each SAV bed was defined by a polygon with a linear data point density of 127 per chart inch (50 per cm, 5 meter ground resolution). The total number of points defining any SAV bed is dependent on overall bed size. The SAV bed perimeter was stored as X and Y coordinates in centimeters from the quadrangle origin (lower left comer). TESTS OF PRECISION AND ACCURACY Prior and subsequent to each digitization session, the NUMONICS instrument was checked manually against a digitizing standard. This was accomplished by securing a diazo mylar quadrangle with SAV polygons to the digitizing tablet. Then the mylar standard was secured to the same quadrangle and digitized four times. The information from digitizing the standard was transmitted to the 9 SA V beginning of the SAV bed perimeter file on the computer. This same procedure was followed at the end of each digitizing session. When this file was processed by the computer, the digitized area of each standard was compared to the known area of the standard. If a variation between the known and the mean of the observed areas exceeded 1.0%, a warning was printed advising the operator to check the digitizing system. In addition, checks were made with respect to the absolute location of the digitizing standard as secured to the map. A comparison was made between the location of the standard before and after the digitizing session. If the absolute location differed by more than 0.10 cm another warning was printed. Any movement in absolute location can be indicative of digitizer instrument drift or chart movement during the digitization session. These checks assure that the final calculated bed locations are as accurate as possible. Maximum accuracy was maintained by exclusively using mylar quadrangles and standards rather than paper ones which can change scale as a function of changes in air temperature and humidity in the digitizer room. A complete outline of the digitization procedure can be found in Orth et al., 1988. STANDARD OPERATING PROCEDURES FOR QUALITY ASSURANCE/ QUALITY CONTROL Standard operating procedures (SOPs) were developed to facilitate orderly and efficient processing of the 1992 SAV maps and the SAV bed perimeter computer files produced from them, and to comply with the need for consistency, quality assurance, and quality control. SOPs developed include: a detailed procedure outlining 46 steps for digitization of SAV maps; a 47 step checklist for editing SAV perimeter computer files to insure completeness and accuracy; a digitizer log in which all operations were recorded and dated, which was used to guide and record editing operations; and a flow chart used to track progress of all operations including all changes in file names. Examples of these SOPs are in Orth et al., 1988. CHOICE OF REPRESENTATIVE SAV BED Part of the quality assurance/quality control program was designed to isolate and remove anomolous data and to obtain accurate and representative SAV bed polygons. Every SAV bed mean area was the result of at least four independent digitizations of the perimeter of each SAV bed. The computer calculated area for each replication, and the three bed perimeters most similar in terms of area were then used for the calculation of a mean area. The three replicate areas used in the mean area calculation were required to be within 5% or less from that of the mean area. All replicates whose areal differences were in excess of 5% of the mean bed area were flagged by the VIMS quality assurance/ quality control computer program for additional error assesment. The VIMS error rate was normally less than 1%. The replicate bed perimeter whose area was most similar 10 1992 to the mean area was identified as the "best bed" and was chosen as representative of that SAV bed. The"best bed" perimeter coordinate points were then saved by the computer program and transferred to the ARC/INFO GIS system for area calculations and inclusion in the SAV data base. CONVERSION OF SAV PERIMETER POINTS FROM X,Y CENTIMETERS TO UNIVERSAL TRANSVERSE MERCATOR (UTM) COORDINATES IN ARC/INFO 5.0.1 FORMAT The EPA Chesapeake Bay Program Computer Center manages its geographic data base using Environmental Systems Research Institute (ESRI) ARC/INFO Geographic Information System (GIS) (ESRI, 1989). During 1991, the VIMS SAV program began converting its operation from the Prime to ARC/INFO based on a SUN Sparc 2 Unix workstation. With the assistance of the Virginia Department of Environmental Equality, Eco&LkPS Office, procedures were developed in 1991 to convert/ transform the best bed perimeter points from X,Y centimeters to UTM based coordinates in ARC/INFO 5.0.1 format. This involved construction of data transfer files in an ARC/INFO standard format ("generate"). This was done on the VIMS PRIME for each 7.5 minute quadrangle with SAV beds present. Four files per quadrangle were produced: 1. Polygon file containing SAV bed coordinates in digitizer-based centimeters. 2. Attribute file containing SAV bed labels, density, species composition, and dates. 3. Tic file containing map comer locations in digitizer-based coordinates (cm). 4. Geo file containing corresponding latitude and longitude positions for map comers. The "generate" files were then transferred to the workstation and imported into the ARC/ INFO system. A set of automated ARC/INFO routines were used to input quadrangle-based SAV "generate" data into ARC/INFO 5.0.1 format, and to assist in interactive editing of SAV polygons. ARC /INFO-based SAV polygons were displayed and edited by VIMS staff. SAV polygons appearing on the computer display screen were compared to their counterparts on the diazo mylar quadrangles. Discrepancies and artifacts were edited using a suite of ARC/INFO editing "tools". ARC/INFO-based data sets were considered satisfactory for submission to the EPA when the shape, location, and label of all SAV beds corresponded to those on the diazo mylar quadrangles. ARC/INFO-based SAV data were transformed to UTM coordinates, Zone 18, and submitted to EPA for final review, analysis, and deposition to archives. CALCULATION OF 1992 SAV AREAS The SAV coverages in UTM ARC/INFO Zone 18 format were used to calculate area in square meters for all SAV beds. These areas are reported as USGS 7.5 SA V minute quadrangle totals in Table 4, and section and zone totals in Tables 5 and 6. Section and zone totals were calculated by using an overlay operation of the polygons on the SAV beds in ARC/INFO. The definition of the sections used in this analysis are provided in Table 3. ORGANIZATIONAL PROCEDURES FOR ANALYSIS AND DISCUSSION Discussion of the distribution of SAV in the Chesapeake Bay and tributaries has been organized into three zones as established by Orth and Moore (1982) and modified by Orth et al., (1989) (Fig. 7). The Lower Bay zone is the area from the entrance of the bay to a line originating fr6m Smith Point at the mouth of the Potomac River, to approximately 3 nautical miles south of Tangier Island, then extending to just below the Little Annernessex River mouth. From this line north to the Chesapeake Bay Bridge at Kent Island is the area referred to as the Middle Bay zone. The area between the Chesapeake Bay Bridge and the Susquehanna Flats is referred to as the Upper Bay zone. The salinity within each zone roughly coincides with the major salinity zones of estuaries: polyhaline (18-250/oo), Lower zone; mesohaline (5-180/oo), Middle zone; oligohaline (0.5-5 O/oo), Upper zone. Although the major rivers and smaller tributaries of Chesapeake Bay have their own salinity regimes, the distribution of SAV in each river is discussed within the zone where it connects to the bay. In addition, 21 sections of the bay are identified for a more detailed discussion of SAV distribution (Fig. 7, Table 3). These sections, which were first delineated for the 1984 SAV survey (Orth et al., 1985) and slightly modified for the 1987 SAV survey (Orth et al., 1989), denote relatively distinct parts of Chesapeake Bay and its tributaries that are readily identifiable. The section boundaries used for analysis and discussion of the 1992 SAV distribution and abundance data were used for the 1987, 1989, 1990, and 1991 reports (Orth et al., 1989; Orth and Nowak, 1990, Orth et al., 1991, Orth et al., 1992). Sections 1 through 4 are located in the Upper Bay zone, sections 5 through 13 in the Middle Bay zone, and sections 14 through 21 in the Lower Bay zone. SAV distribution in Chincoteague Bay is presented and discussed separately from the Chesapeake Bay. Appendix B gives the latitude and longitude of the boundary points of each Chesapeake Bay section and of Chincoteague Bay in decimal degrees. 12 DENSITY CLASS 5 Very Sparse 0-10% 15 Sparse 25 10-40% 35 V16 N! 45 15 2;c Moderate 40-70% 65 7511 2 21 850 N H Dense 70-100% 95M 0 E PERCENT CROWN COVER Figure6.

(Refer to Figure 7 and Appendix B for boundary locations.) 16 1992 GROUND SURVEYS AND OTHER DATA BASES Ground surveys were accomplished by cooperative efforts from a number of agencies and individuals. Although not all areas of the bay were surveyed, the data did provide valuable supplemental information. The surveys confirmed the existence of some SAV beds mapped from the 1992 aerial photography, as well as SAV beds not visible from the photography. The surveys also provided species data for many of the SAV beds. Ground survey information supplied to VIMS researchers was included on the SAV distribution and abundance maps reproduced in Appendix C. Each survey was designated by a unique symbol to identify the different methods of sampling. In most cases, the symbols on the SAV maps (Appendix C) have been enlarged and offset from the actual sampling point to avoid confusion with the mapped SAV bed. Where species information was available, it was included on the map. Because of space limitations on the maps reproduced in Appendix C, occasionally one or more survey points were combined where the information was duplicated. All ground survey data supplied to VIMS are tabulated in either Appendix E or F. In Maryland, ground survey data were obtained in 1992 by the Patuxent River Park staff, through three SAV research projects, and by the Citizens' volunteer survey. Data from the foUowing three surveys were compiled by the USFWS. Patuxent River ground survey data were obtained by the Maryland-National Capital Parks and Planning Commission Patuxent River Park staff. The Essex Community College SAV Research Group of Baltimore County, Maryland, contributed ground survey data for quadrangle 14. The Citizens' volunteer survey, under the guidance of the USFWS and the Chesapeake Bay Foundation (CBF), identified SAV locations and SAV species when possible throughout various areas of the Chesapeake and Chincoteague bays. Volunteers, who were recruited through press releases, newsletters, and personal letters, were provided with a SAV identification guide, reduced 1990 SAV maps to aid in the location of SAV beds, and data sheets for reporting visits to numerous sites around the bays. USFWS staff compiled data from the three surveys and mapped the data on copies of 1990 SAV distribution maps (USGS 7.5 minute quads with 1990 SAV beds). These maps were supplied to VIMS SAV researchers and transferred to the 1992 SAV distribution maps reproduced in Appendix C. Data from the three surveys were also tabulated by USFWS. This table became the basis of the much expanded table published in Appendix E. One 1992 SAV project being conducted on the Susquehanna Flats by Stan Kollar of Harford Community College, Maryland, provided data in the form of species presence by percentage. A SAV research group at the University of Maryland Horn Point Environmental Laboratories (HPEL) also provided 1992 ground survey data in collaboration with the VIMS research team. Shorelines of the Choptank, Miles, Wye, and Chester rivers, as well as Eastern Bay and Trippe Bay, were sampled from June 26 through August 27. Samples of the bottom were taken every 20-50 m using a rake dragged along the bottom. This survey concentrated on the lower half of the Choptank River from the Hom Point Laboratory to the mouth of the river. In addition, 12 transects were run perpendicular to the shoreline where SAV 17 SA V abundance was estimated every 10 m for a distance of 200 m. Choptank River and Eastern Bay ground survey data are presented in Appendix F. For those areas in Virginia waters where aerial photographic evidence of SAV beds was inconclusive, photoverification. was accomplished by ground truth surveys. Observations were principally made from small boats and by divers snorkeling over areas indicated from the photographs. In the York, Piankatank, and Rappahannock rivers, where VIMS researchers had transplanted SAV (principally eelgrass), transplant sites were also examined carefully by divers for any extant SAV. VIMS scientists also surveyed a number of sites in the Chesapeake Bay as part of an intensive quantitative SAV study (VIMS, unpublished data). Data for Virginia waters were also collected by the Citizens' volunteer survey (compiled by the USFWS). In addition, a great deal of ground survey information could be extrapolated from earlier studies (Orth et al., 1979; Orth and Moore, 1982). SAV beds in the lower bay contain primarily one or two species and most areas have not undergone wide fluctuations in distribution and abundance since the first bay-wide survey in 1978. Ground survey data from all sources reported here were added to the USFWS table and each SAV siting was cross-referenced with its associated 1992 SAV bed location. This expanded ground survey table is presented in Appendix E. 18 1992 RESULTS DATA PRESENTATION SAV distribution data are presented by quadrangle (Table 4), by section and zone (Table 5), by quadrangles within a section (Table 6), and by density class (1, 2, 3, 4) for each section (Table 7). Quadrangle maps annotated with all SAV beds are presented in Appendix C, while individual bed areas for each quadrangle are given in Appendix D. Appendix E tabulates all ground truth data for 1992. Appendix F lists latitude and longitude coordinates of the ground survey of the Choptank River and Eastern Bay area by HPEL staff. The 1992 SAV distribution data and species occurrences are first discussed relative to the Upper, Middle, and Lower Bay zones, respectively. The 21 sections of the Chesapeake Bay and Chincoteague Bay are then discussed individually, and the data compared to results from the 1991 survey of SAV distribution and abundance (Orth, et al., 1992). SAV is plotted for each section and for Chincoteague Bay in Figures 8 through 29. SAV beds are plotted in red, and bold, black lines represent section boundaries. USGS 7.5 minute quadrangles are represented by a grid of numbered rectangles (refer to Table 2 for quadrangle names listed by map number). Specific names of rivers, creeks, or points of land which are not found on the section plots, are on the quadrangle maps for that section. 1992 SUMMARY In 1992, the Chesapeake Bay had 28,591 hectares of SAV, compared to 25,623 hectares in 1991, with 2,516 hectares (8.7%), 13,713 hectares (48.0%), and 12,362 hectares (43.2%) occurring in the Upper, Middle, and Lower Bay zones, respectively (Figs. 1, 2, and 3). SAV increased in most sections in 1992 with the largest increases in SAV abundance occurring in the Eastern Bay and Choptank River sections. SAV declined in only a few sections, notably the Upper Potomac River section. Upper Bay Zone In 1992 in the Upper Bay zone, 71.2% (1,792 hectares) of the SAV was located in the Susquehanna Flats (Section 1). Overall abundance of SAV increased from the 1991 level (1,684 hectares), while the density of the beds in 1992 increased slightly from 1991. In the flats, 88.6% of all SAV beds were classified as very sparse in 1992 (0-10% coverage) (Table 7; Figure 3), the same as in 1991, but 8.0% of beds were classified as dense in 1992 (70-100% coverage), an increase of 1.0% compared to 1991. Myriophyllum spicatum, H. dubia, V. americana, H. verticillata, and C. demersum were among the six species reported from many of the SAV beds. In the Upper Eastern Shore (Section 2) there were 283 hectares of SAV in 1992 (43 hectares less than in 1991) located principally in the Elk and lower 19 SA V TABLE4 Total Area of SAV in Hectares by USGS 7.5 Minute Quadrangles for 1991 and 1992.

The Upper Western Shore (Section 3) had 186 hectares of SAV concentrated in Saltpeter, Seneca, and Dundee creeks, compared to 91 hectares recorded in 1991. Myriophyllum spicatum, E. canadensis, and C. demersum were frequently cited. In the Chester River (Section 4) SAV abundance (255 hectares) was up 198 hectares from 1991. SAV was most abundant adjacent to Eastern Neck, Eastern Neck Island, and in Gray's Creek in the lower Chester River. Ruppia maritima was most commonly cited. Middle Bay Zone In 1992,43.7% (5,994 hectares) of the SAV in the Middle Bay zone was found in the Mid-Bay Island Complex (Section 13) which includes the broad shoal area between Smith and Tangier Islands. This is an increase of 287 hectares over 1991. In this zone, 22.2% (3,047 hectares) of the SAV was present in the Middle Eastern Shore (Section 12), primarily in the Barren Island-Honga River area, the Big and Little Annemessex rivers, and the lower section of the Manokin River, with R. nwritima reported most frequently. Little or no SAV was mapped from the Central Western Shore (Section 5), Patuxent River (Section 8), and Middle Western Shore (Section 9). Citizens' surveys reported Z. palustris at numerous locations in the South and Sevem rivers while 12 species were reported from the small marsh creeks in the upper Patuxent River. The Middle Bay zone also includes the entire Potomac River, where 3,033 hectares of SAV were present in 1992. SAV was concentrated in two distinct regions: 1) the Upper Potomac River (Section 11) with 2,462 hectares; and 2) the upper portion of the Lower Potomac River (Section 10) with 571 hectares, including Nanjernoy Creek and Port Tobacco River. The total abundance of SAV in the Upper Potomac section decreased from 1991 by 554 hectares. Declines in SAV were most notable in the Alexandria, Mt. Vernon, and Fort Belvoir quadrangles, primarily in the mainstern river, the southern edge of the large bed at the Woodrow Wilson Bridge, and in Piscataway Creek. Ground survey data were limited in this section in 1992 to only Citizens' surveys with five species reported: M. spicatum, V. americana, H. verticillata, N. guadalupensis and C. demersum. SAV increased in the Eastern Bay and Choptank River sections for the first time since the late 1980's. SAV in the Eastern Bay (Section 6) increased 486 hectares from 1991 to a total of 554 hectares in 1992, while in the Choptank River (Section 7) it increased 971 hectares from 1991 to a total of 1,085 hectares in 1992. Most of the increase in the Eastern Bay occurred in the Miles River, while in the Choptank River section, SAV beds were most abundant in Harris and Broad creeks and in Trippe Bay. Three species were reported from Sections 6 and 7, with R. maritima most commonly cited. 37 SA V Lower Bay Zone Distribution and abundance of SAV in 1992, in the Lower Bay zone, were similar to 1991. In this zone, 47.9% (5,920 hectares) of the SAV was found in the Lower Eastern Shore (Section 14) around the Fox Islands and the mouths of major creeks (i.e. Cherrystone Inlet and Hungars, Mattawoman, Occahannock, Craddock, Pungoteague, and Onancock creeks). Along the western shore of the Chesapeake Bay, SAV was abundant in Mobjack Bay (Section 18) (14.7% of SAV in the Lower Bay zone), in the lower York River (Section 19) (6.7% of SAV in the Lower Bay zone), and in the Lower Western Shore (Section 20), specifically Back River and the Drum Island Flats area adjacent to Plum Tree Island (16.4% of SAV in the Lower Bay zone). There were 778 hectares of SAV mapped in the Reedville Region (Section 15) in 1992, a 22.5% increase over 1991. There were 396 hectares of SAV identified in 1992 in the New Point Comfort Region (Section 17) compared to 339 hectares in 1991. SAV abundance was up 15.3% from 1991 in both the Piankatank and Rappahannock rivers (Section 16). The James River (Section 21) had less than 4 hectares of SAV in 1992. Zostera marina and R. maritima were the abundant species in this zone. Chincoteague Bay SAV in the Chincoteague Bay section increased in distribution with 3,324 hectares mapped in 1992 compared to 2,746 hectares in 1991. Most of the SAV in Chincoteague and Sinepuxent bays, which consisted of Z. marina and R. maritima, was located along the eastern side of the bay behind Assateague Island. Some small beds, consisting of R. maritima, were located along the western side of Isle of Wight and Assawoman bays. DISCUSSION OF SECTIONS ARRANGED WITHIN ZONES Upper Bay Zone 1. Susquehanna Flats There were 1,792 hectares of SAV in the Susquehanna Flats section in 1992 (Tables 4-7; Figure 8; Appendix C, Maps 2,3, and 9) compared to 1,684 hectares mapped in 1991. Eight percent of the total coverage of SAV in this section was dense (class 4), 1.6% was moderate (class 3), 1.8% was sparse (class 2), and 88.6% was very sparse (class 1) (Table 7; Figure 3). SAV beds were located principally in two main areas: 1) sparse to dense fringing beds in the Susquehanna River consisting primarily of M. spicatum, with H. dubia, V. americana, H. verticillata, and C. demersum from Robert Island to the river mouth at Havre de Grace on. the west side, to Stump Point at the mouth of Mill Creek on the east side, and in Mill Creek, Furnace Bay, and Baker Cove; and 2) a large area of very sparse SAV 38 002 003 004 005 S u hanna R.

In addition, SAV beds were again mapped in Spesutie Narrows where most SAV is found as small, fringing beds of M. spicatum and H. verticillata. The Citizens' Survey reported M. spicatum and Potamogeton crispus in the Northeast River. A total of six species (M. spicatum, H. dubia, V. americana, H. verticillata, C. demersum, P. crispus) have been reported either by Stan Kollar of Harford Community College or the Citizens' Survey. 2. Upper Eastern Shore There were 283 hectares of SAV mapped for the Upper Eastern Shore section in 1992 (Tables 4-7; Figure 9; Appendix C, Maps 4, 5, 9, 10, 15, 16, and 17) compared to 326 hectares mapped for 1991. In this section 1.1% of the total coverage of SAV was dense (class 4),1.6% was moderate (class 3), 11.0% was sparse (class 2), and 86.3% was very sparse (class 1) (Table 7; Figure 3). Principal locations of beds were in the Elk River, Swan Creek, lower Sassafras River, Still Pond, and the mouth of Chum Creek. Very little or no SAV was mapped in the Bohemia River or along the mainstem of the bay from Still Pond to Swan Point. Ground survey data from Stan Kollar and the Citizens' survey reported 5 species in this section (Maps 4, 9,10,15,16, and 17) with M. spicatum and V. americana found most frequently, especially in the Elk River. Potamogeton perfoliatus, P. crispus, and Potamogeton pectinatus were also reported. 3. Upper Westem Shore There were 186 hectares of SAV mapped from the aerial photographs in 1992 for the Upper Western Shore section (Tables 4-7; Figure 10; Appendix C, Maps 7,8, 9, 13 and 14) compared to 91 hectares in 1991. Of the total coverage of SAV in this section 7.3% was dense (class 4), 55. 1% was moderate (class 3), and 37.6% was sparse (class 2) (Table 7; Figure 3). SAV beds were concentrated in Saltpeter, Dundee, Seneca, and Romney creeks, and Middle River, in and adjacent to Galloway Creek. SAV was mapped in the lower Spesutie Narrows in 1992, the first time SAV was mapped in this part of section 3. Very little or no SAV was again reported in the Back, Patapsco, Bush, Gunpowder, and Magothy rivers. Ground survey data from the Citizen's survey and Essex Community College reported 6 species in this section (Maps 7, 13, 14, 19, 23, and 24) with M. spicatum, E. canadensis, and C. demersum were found most frequently in Saltpeter, Dundee, and Seneca creeks, where SAV has been most abundant. Vallisneria americana and Z. palustris were also reported in these same areas but less frequently. Zannichellia palustris and R. maritima were reported from other creeks and rivers with Z. palustris most numerous at locations in the Magothy River. 40 003 004 005 Susquehanna Flats 009 010 Oil -40 RfIvefy fras R. 3till Pond @@reek 015 016 017 C, 022 won Point 020 021 4S Figure 9.

Chester River There were 255 hectares of SAV in the Chester River section in 1992 (Tables 4-7; Figure 11; Appendix C, Maps 20, 21, 26, and 33) compared to 57 hectares in 1991. In this section, 1.8% of the total coverage of SAVwas dense (class 4), 31.7% was moderate (class 3), 39.9% was sparse (class 2), and 26.6% was very sparse (class 1) (Table 7; Figure 3). This is the first year in which SAV has increased in this section. SAV has continually declined in this section since 1987 when 515 hectares of SAV were mapped, and large, dense beds of R. maritima dominated this section. Most of the SAV, and where the greatest increase occurred, was located adjacent to Eastern Neck and Eastern Neck Island, especially near Eastern Neck Narrows, and in Grays Creek, a tributary entering the Chester River. Additional SAV beds in the Chester River were located in Robin Cove and adjacent to Quaker Neck. Rock Hall Harbor, and Haven, Swan, and Huntingfield creeks, located above Eastern Neck on the Chesapeake Bay, supported the remaining SAV beds in this section. Three species of SAV were reported from this section by Citizens' and HPEL surveys in 1992: Potamogeton perfoliatus, Z. palustris, and R. maritima (Maps 20, 21, and 26). Ruppia maritima was most commonly cited, especially in the Chester River. HPEL staff ran a 200 m transect in Fryingpan Cove in Eastern Neck Narrows. They found P. perfoliatus occurring along 5 points of the transect and R. maritima occurring at only 1 point. Plants were very patchy, with 2% or less of the sample being SAV. No plants were found beyond 100 m. A second transect conducted along the eastern shore of the lower Chester River adjacent to Robin Cove found no SAV. Middle Bay Zone 5. Central Western Shore There was no SAV observed from the aerial photography in the Central Western Shore section in 1992 (Tables 4-7; Figure 12). This was similar to 1991. Citizens' surveys found Z. palustris at numerous locations in the Severn and South rivers (Maps 23 and 30) and at one location at the mouth of the Rhode River (Map 35). Ruppia maritima was reported at a few locations in the South and Rhode rivers. 6. Eastern Bay There were 554 hectares of SAV identified from the Eastern Bay section in 1992 (Tables 4-7; Figure 13; Appendix C, Maps 32, 33, 36, and 37) compared to 68 hectares reported in 1991, a 714.7% increase. In this section, 10.4% of the total coverage of SAV in this section was moderate (class 3), 33.8% was sparse (class 2), and 55.8% was very sparse (class 1) (Table 7; Figure 3).

Other SAV beds were located in the lower Cox Creek, Wye River, the eastern shore of lower Kent Island, Parson Island, Harbor Cove on Eastern Bay, Piney Neck, Crab Alley Bay, and between Wades Point and Claiborne on Eastern Bay. Only two species of SAV were reported from this section by Citizens' and HPEL surveys: Z. palustris, R. maritima (Maps 32, 33, 36, and 37; Appendix F) with R. maritima most commonly cited. HPEL staff conducted three transects in the Eastern Bay area. Ruppia maritima accounted for less than 2% cover at 7 points along a transect run from the western side of Parsons Island. No SAV was found beyond 170 m. Ruppia maritima was more abundant along a transect run from the southern tip of Kent Island between Kent and Long Point. This species was found at 7 points out to 150 m from the shoreline accounting for up to 90% of the coverage at the inshore stations (30 m from shore). At the third transect between Claiborne and Wades Point R. maritima was abundant at only two points in the first 30 m and was absent from the remainder of the transect. 7. Choptank River There were 1,085 hectares of SAV observed in the Choptank River section in 1992 (Tables 4-7; Figure 14; Appendix C, Maps 43, 44, 51, 52, 53, and 62) compared to 114 hectares in 1991, an increase (851.8%) that is greater than any other section in 1992. In this section, 1.3% of the total coverage of SAV was dense (class 4), 25.6% was moderate (class 3), 54.2% was sparse (class 2), and 18 *.9% was very sparse (class 1) (Table 7; Figure 3). SAV was found in moderate to sparse beds in Blackwalnut Cove at the southern tip of Tilghman Island; Cators, Oyster, Point, and Cook Point coves; James Island; Brannock Bay; Tred Avon River; Harris, Broad, Chapel, Island, Irish, and Covey creeks; and off the Little Choptank River in Hudson and Brook creeks. Three species of SAV were reported from this section by Citizens' and HPEL surveys: Z. palustris, R. maritima, and P. pectinatus (Maps 43, 44, 46, 51, 52, and 53; Appendix F) with R. maritima most commonly cited. HPEL staff conducted seven transects in the Choptank River area. Ruppia maritima accounted for less than 20% cover at 6 points along a transect run in Brannock Bay with no SAV reported beyond 150 m. No SAV was found along a second transect just north of the Brannock Bay transect although the aerial survey mapped SAV in the area. No SAV was found along a transect run from the western side of Ragged Island at the mouth of the Little Choptank River. Ruppia maritima was more abundant along a transect run from the southern tip of Tilghman Island at Blackwalnut Point. SAV was present at all points out to 200 m and was present beyond the transect. A transect run from Cooks Point Cove found no SAV although the aerial survey reported abundant SAV. However, the transect was run off a point from which no SAV was reported in the aerial survey. The Chapel Creek transect had R. maritima occurring along the entire 200 m transect, with 14 points have greater than 50% coverage of SAV. The aerial survey has consistently reported SAV in this area.

Patuxent River There was no SAV observed from the aerial photography in the Patuxent River section in 1992 (Tables 4-7; Figure 15) similar to 1991. The Patuxent River Park and Citizens' surveys reported 12 species occurring in this section primarily in the marsh creeks in the upper portions of the Patuxent River (Maps 41, 60, and 159): E. canadensis, C. demersum, V. americana, Z. palustris, N. guadalupensis, Najas gracillus, Najas minor, P. crispus, Potamogeton pusillus, P. pectinatus, and Potamogeton epihydrus. Zannichellia palustris and R. maritima were reported from the lower portion of the Patuxent River in Saint Leonard, Pearson and Harper creeks (Maps 61 and 71). 9. Middle Western Shore There were no SAV beds identified in the Middle Western Shore section in 1992 (Tables 4-7; Figure 16) similar to 1991. Zannichellia palustris and R. maritima were reported by Citizens' surveys from Goose Creek just south of the Patuxent River mouth (Map 71). 10. Lower Potomac River There were 571 hectares of SAV identified in the Lower Potomac River section as indicated on the 1992 aerial photography (Tables 4-7; Figure 17, Appendix C, Maps 56, 57, 58, 65, 66, 67, 80, and 89) compared to 581 hectares reported in 1991. In this section, 43. 1% of the total coverage of SAV was dense (class 4), 10.7% was moderate (class 3), and 46.2% was sparse (class 2) (Table 7; Figure 3). Most of the SAV occurred in the region near the Route 301 bridge, and along Nanjemoy Creek and Port Tobacco River, as well as along the shoreline adjacent to these two creeks. SAV beds were found fringing the eastern side of Mathias Point Neck to an area just below the Route 301 bridge. Several small beds were observed in Machodoc, Rosier, and Cuckhold creeks, the St. Marys River, and in Calvert Bay at the mouth of Smith Creek. Ground survey data was available only from Citizens' surveys for Maps 66, 78, 80, and 98. Zannichellia palustris was reported from two creeks off the Lower Machodoc Creek (Map 78) and in the St. Marys River (Map 80). Ruppia maritima was reported from the St. Marys River and Cubitt Creek in the lower Potomac River. Three species were reported from off Mathias Point Neck: V. americana, E. canadensis, and P. perfoliatus. 49 049 050 060 061 059 069 070 Ok 071 Figure 15.

Upper Potomac River There were 2,462 hectares of SAV mapped in the Upper Potomac River section (Tables 4-7; Figure 18; Appendix C, Maps 28, 34, 39, 40, 47, 48, 55, 64, 65, and 161) in 1992 compared to 3,016 hectares reported in 1991, a decrease of 18.4%. A total of 72.3% of the SAV beds were densely vegetated (class 4), 8.9% was moderate (class 3),17.3% was sparse (class 2), and 1.5% was very sparse (class 1) (Table 7; Figure 3). Declines in SAV were most notable in the Alexandria (Map 34), Mt. Vernon (Map 40), and Fort Belvoir (Map 39) quadrangles, in particular in the mainstem of the Potomac River, the southern edge of the large bed at the Woodrow Wilson Bridge, and in Piscataway Creek. SAV beds increased in size in Aquia Creek. SAV beds were first noted in Potomac Creek although COG reported H. verticillata at one location in 1991. SAV is still absent from Occoquan and Belmont bays (although COG reported some SAV in 1991 in Belmont Bay) but some SAV beds were located and mapped at the mouth of the Occoquan River in 1992. Ground survey data was available only from Citizens' surveys for Map 40. Five species were reported: M. spicatum, V. americana, H. verticillata, N. guadalupensis and C. demersum. 12. Middle Eastern Shore There were 3,047 hectares of SAV identified in the Middle Eastern Shore section (Tables 4-7; Figure 19; Appendix C, Maps 62, 63, 72, 73, 74, 82, 83, 84, 92, 93, 100, and 101) in 1992 compared to 2,178 hectares reported in 1991. In this section, 37.7% of the SAV was dense (class 4), 35.6% moderate (class 3), 22.6% sparse (class 2), and 4.0% very sparse (class 1) (Table 7; Figure 3). SAV beds were very abundant in: 1) the Honga River, 2) between Barren Island and Meekins Neck-Upper Hooper Island, and 3) the lower Manokin and the Big and Little Annemessex rivers. No SAV beds were observed in Fishing and Monie bays, and in the Nanticoke and Wicornico rivers. Ground survey data were available for this section in 1992 from Citizens' surveys (Maps 72,74,82,84, 100, 101). Ruppia maritima was reported most frequently, while Z. palustris was present in only one area (Map 74). 13. Mid-Bay Island Complex There were 5,994 hectares of SAV mapped in the Mid-Bay Island Complex in 1992 (Tables 4-7; Figure 20; Appendix C, Maps 83, 91, 92, 99, 100, 107, and 179) compared to 5,707 hectares reported in 1991, a 5.0% increase. This section contains 20.9% of the SAV in the entire Chesapeake Bay, slightly less than the 22.3% in 1991. However, the density of SAV has decreased since 1991. In 1992 15.4% percent of the SAV within this section was in dense beds (class 4) compared to 59.0% in 1991. In the rest of the classes 55.4% was moderately dense 53 034 039 s fau)ay Ou sto reek C 040 OCCOq 047 t,CO 048 161 uan Ma tawoman Creek Creek C PCXWa7nS C eek 055 056 05 Aqu a Cr ek 066 065 064 Figure 18.

SAV is present in dense to moderate beds along the broad, expansive shoal area between Tangier Island and Smith Island; the eastern side of Tangier Island; Mailboat Harbor; and on the shoals and in the coves adjacent to Bloodsworth, South Marsh, Holland, Adam, and Spring islands. There was no ground survey data available for this section in 1992, although both Z. marina and R. maritima have been reported previously throughout this section. Lower Bay Zone 14. Lower Eastern Shore There were 5,920 hectares of SAV observed in the Lower Eastern Shore section in 1992 (Tables 4-7; Figure 21; Appendix C, Maps 100, 101, 102, 107, 108, 109, 113, 114,119,124,133,134, and 142) compared to 5,720 hectares reported in 1991. In this section 39.8% of the total SAV was dense (class 4), 18.2% was moderate (class 3), 33.3% was sparse (class 2), and 8.7% was very sparse (class 1) (Table 7; Figure 3). Large, dense beds continue to persist at the mouth of Cherrystone Inlet near Cape Charles, and at the mouths of Hungars, Mattawoman, Occohannock, Craddock, Pungoteague, Onancock, and Chesconessex creeks. Large, dense beds also occur at the Big Marsh area near Chesconessex Creek, at Webb Island off the mouth of Deep Creek, and on the large shoal area on the eastern side of the Fox and Cedar Islands. There was no SAV from Elliots Creek just below Cape Charles to Fisher1rLans Island at the mouth of Chesapeake Bay. Ground survey data were limited in this section. Although both Z. marina and R. maritima have been reported previously throughout this section, the Citizens' surveys reported Z. marina and R. maritima in Nassawadox Creek (Map 124) and R. maritima in Beasley Bay (Map 109) while VIMS staff reported Z. marina at the mouth of Kings Creek near Cape Charles (Map 133). 15. Reedville Region There were 778 hectares of SAV identified in the Reedville Region in 1992 (Tables 4-7; Figure 22; Appendix C, Maps 106 and 112) compared to 635 hectares reported in 1991. In this section, 22.5% of the total coverage of SAV was dense (class 4),27.4% was moderate (class 3),35.5% was sparse (class 2), and 14.6% was very sparse (class 1) (Table 7; Figure 3). Zostera marina and R. maritima were the two species identified by VIMS and Citizens' surveys (Maps 106 and 112). Most beds were found in Little, Fleets, and Ingram bays; Dymer, Indian, Dividing, Ball, and Cloverdale creeks; Dameron Marsh; and adjacent to Fleeton Point. 57 149 Wond Wt Of 099 100 00t Al Fox IS101 TQNier 108 Wand 107 0 ock "k 113 t" Ue ed 114 Qj CZ? *ek 12Y 40 y 133 134 F4J C7-7 g 0 142 WC 6, @Fo POW T=)Vl 1 "_/'*k AJ J@l 2; Figure 21.

Rappahannock River Complex There were 587 hectares of SAV observed in the Rappahannock River Complex in 1992 (Tables 4-7; Figure 23; Appendix C, Maps 110, 111, 117,118, and 123) compared to 509 hectares reported in 1991. In this section 40.7% of the total coverage of SAV was dense (class 4), 15.8% was moderate (class 3), 30.3% was sparse (class 2), and 13.1% was very sparse (class 1) (Table 7; Figure 3). Dense, moderate, and sparse beds were present in the Corrotoman River; along the north shore of the Rappahannock River between Carters Creek and the Corrotoman River; Milford Haven; the lower Piankatank River; and the mouth of the north shore of the Rappahannock River between Mosquito Point'and Deep Hole Point. Ruppia maritima is the dominant species in both the Rappahannock and Piankatank rivers while Z. marina is found in only isolated beds (from ground surveys by VIMS staff of SAV in Maps 110, 111, 117,118, and 123) e.g. Burtons Point in the Piankatank River. One Citizens' survey observation reported R. maritima in Map 110 off Towles Point in the Rappahannock River. The large SAV bed adjacent to Windmill Point that has been slowly expanding naturally since 1989, with both Z. marina and R. maritima present now covers an area of 28.4 hectares, up from 13.3 hectares in 1991. SAV beds are abundant in Milford Haven but are principally located along the north shore with both Z. marina and R. maritima present. 17. New Point Comfort Region There were 396 hectares of SAV identified in the New Point Comfort Region in 1992 (Tables 4-7; Figure 24; Appendix C, Map 123,132, and 177) compared to 339 hectares reported in 1991. In this section 34.7% of the total coverage of SAV was dense (class 4), 2.4% was moderate (class 3), 62.8% was sparse (class 2), and 0. 1% was very sparse (class 1) (Table 7; Figure 3). SAV beds were present from New Point Comfort to just north of Horn Harbor. SAV beds were visible in the northern end of Winter Harbor for the first time since 1978. VIMS staff confirmed the presence of SAV at this location which consisted of both Z. marina and R. maritima (Map 123), the same species present in other beds in this section. Because reproductive shoots of Z. marina were observed (this species flowers in the second year of its life cycle), it is likely that these beds were previously present. 18. Mobjack Bay Complex The Mobjack Bay Complex contained 1,818 hectares of SAV in 1992 (Tables 4-7; Figure 25; Appendix C, Maps 122,123,131,132 and 177) compared to 1,788 hectares reported in 1991. SAV beds consisting of both Z. marina and R. maritima (ground surveys were made by VIMS staff and citizens of SAV in Maps 131 and 132) were abundant along the entire shoreline of Mobjack Bay, as well as in the 60 Fleel on Pt. 106 ,4 Dameron Marsh Dy n Cr.

Rappahannock River Complex There were 587 hectares of SAV observed in the Rappahannock River Complex in 1992 (Tables 4-7; Figure 23; Appendix C, Maps 110, 111, 117,118, and 123) compared to 509 hectares reported in 1991. In this section 40.7% of the total coverage of SAV was dense (class 4), 15.8% was moderate (class 3), 30.3% was sparse (class 2), and 13.1% was very sparse (class 1) (Table 7; Figure 3). Dense, moderate, and sparse beds were present in the Corrotoman River; along the north shore of the Rappahannock River between Carters Creek and the Corrotoman River; Milford Haven; the lower Piankatank River; and the mouth of the north shore of the Rappahannock River between Mosquito Point'and Deep Hole Point. Ruppia maritima is the dominant species in both the Rappahannock and Piankatank rivers while Z. marina is found in only isolated beds (from ground surveys by VIMS staff of SAV in Maps 110, 111, 117,118, and 123) e.g. Burtons Point in the Piankatank River. One Citizens' survey observation reported R. maritima in Map 110 off Towles Point in the Rappahannock River. The large SAV bed adjacent to Windmill Point that has been slowly expanding naturally since 1989, with both Z. marina and R. maritima present now covers an area of 28.4 hectares, up from 13.3 hectares in 1991. SAV beds are abundant in Milford Haven but are principally located along the north shore with both Z. marina and R. maritima present. 17. New Point Comfort Region There were 396 hectares of SAV identified in the New Point Comfort Region in 1992 (Tables 4-7; Figure 24; Appendix C, Map 123,132, and 177) compared to 339 hectares reported in 1991. In this section 34.7% of the total coverage of SAV was dense (class 4), 2.4% was moderate (class 3), 62.8% was sparse (class 2), and 0.1% was very sparse (class 1) (Table 7; Figure 3). SAV beds were present from New Point Comfort to just north of Horn Harbor. SAV beds were visible in the northern end of Winter Harbor for the first time since 1978. VIMS staff confirmed the presence of SAV at this location which consisted of both Z. marina and R. maritima (Map 123), the same species present in other beds in this section. Because reproductive shoots of Z. marina were observed (this species flowers in the second year of its life cycle), it is likely that these beds were previously present. 18. Mobiack Bay Complex The Mobjack Bay Complex contained 1,818 hectares of SAV in 1992 (Tables 4-7; Figure 25; Appendix C, Maps 122,123,131,132 and 177) compared to 1,788 hectares reported in 1991. SAV beds consisting of both Z. marina and R. maritima (ground surveys were made by VIMS staff and citizens of SAV in Maps 131 and 132) were abundant along the entire shoreline of Mobjack Bay, as well as in the 60 C') Corrotoman River UO Carter P 112 Win Jmil Pt. 116 117 118 Gwyr n Isko d 122 1 rd Vaven 23 Figure 23.

The Mobjack Bay area continued to harbor some of the more extensive SAV beds on the western shore of the lower Chesapeake Bay. In this section 70.6% of the total coverage of SAV was dense (class 4), 10.8% was moderate (class 3), 14.0% was sparse (class 2), and 4.6% was very sparse (class 1) (Table 7; Figure 3). 19. York River There were 830 hectares of SAV observed in the York River section in 1992 (Tables 4-7; Figure 26; Appendix C, Maps 131, 132, 139, and 140) compared to 804 hectares reported in 1991. In this section 82.8% of the total coverage is classified as dense (class 4), while 3.0% was moderately dense (class 3), 10.7% was sparse (class 2), and 3.5% was very sparse (class 1) (Table 7; Figure 3). Ground survey information was available for Maps 131, 132,139, and 140 from VIMS surveys. Dense SAV beds, consisting of both Z. marina and R. maritima were located principally along the north shore from Gloucester Point to the mouth of the river. SAV beds were absent upstream of Gloucester Point along the north shore except for one small bed of Z. marina near Gloucester Point, a result of a VIMS transplanting project using seeds in 1989, 1990, and 1991. Zostera marina was transplanted using whole plants to Mumfort Island, Catlett Island and Clay Bank along the north shore and Yorktown along the south shore in the fall of 1991 by VIMS staff and was present through the spring and summer, 1992. Plants did not survive at Catlett Island and Clay Bank by late summer 1992 but survived at Mumfort Island and Yorktown. The south shore from Yorktown to Goodwin Island remained unvegetated except for one bed adjacent to the Coast Guard Station consisting of R. maritima and a second bed east of the refinery pier. Dense beds were present adjacent to Goodwin Island. 20. Lower Western Shore There were 2,029 hectares of SAV mapped in the Lower Western Shore section in 1992 (Tables 4-7; Figure 27; Appendix C, Maps 140,141,147, and 152) compared to 2,006 hectares reported in 1991. Ground surveys by citizens and VIMS (Maps 140, 141, 147, and 152) reported both Z. marina and R. maritima. In this section 45.1 % of the total coverage was mapped as dense (class 4), 24.9% as moderate (class 3), 15.9% as sparse (class 2), and 14.1% as very sparse (class 1) (Table 7; Figure 3). SAV was mapped in Broad Bay; Back River; the mouth of the Poquoson River off Pasture and Hunts Neck; Drum Island Flats; Poquoson Flats; adjacent to Crab Neck just south of Goodwin Island; and on the south side of Goodwin Island. No SAV was present in the southwest and northwest branches of Back River, or in the Poquoson River, Chisman Creek, and Back Creek. 64 RIZI, 130 131 Clay Bank Mot jack Bxy 132 CU, M sh York RWeT es 139 140 141 Figure 26.

James River There were 3.50 hectares of SAV in the mainstem of the James River in 1992 (Tables 4-7; Figure 28; Appendix C, Map 147), compared to 2.74 hectares in 1991. This single, moderately dense bed, (class 3) (Table 7; Figure 3) located at the mouth of Hampton Creek adjacent to the Veteran's Hospital, consists of Z. marina, the species reported in previous ground surveys. Chincoteague Bay There were 3,324 hectares of SAV identified in Chincoteague and Sinepuxent bays in 1992 with a small amount present in Isle of Wight and Assawoman bays (Tables 4-7; Figure 29; Appendix C, Maps 166,167,168,170,172,173,174, and 175) compared to 2,746 hectares reported in 1991. In this section 58.1% of the total coverage was mapped as dense (class 4), 34.7% as moderate (class 3), 5.4% as sparse (class 2), and 1.8% as very sparse (class 1) (Table 7; Figure 3). The Citizens' survey found both Z. marina and R. maritima throughout Chincoteague and Sinepuxent bays (Maps 168,170,172,173 and 175) but only reported R. maritima in Isle of Wight and Assawoman bays (Maps 166 and 168). All of the SAV in Chincoteague Bay continues to be present on the eastern side of the bay adjacent to Assateague Island. The vegetation remains concentrated in four relatively distinct areas identical to that reported in the earlier surveys from 1986 through 1991. They were located west of the northern end of Chincoteague Island, and west of West Bay, Green Run Bay, and the Tingles Island area. The bed west of Chincoteague Island, the largest in this area, has expanded and is now almost continuous from the island to the offshore areas. SAV in Isle of Wight and Assawoman bays is also present on the eastern side adjacent to Ocean City. 67 _Yl__ IN 46 rM 'Pei 47 149 T A@ Figure 28.
