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; USGS National Center; Harford Community College, 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 1993, the Chesapeake Bay had 29,589 hectares of SAV, compared to 28,591 hectares in 1992, with 2,700 hectares (9.0%), 13,901 hectares (47.0%), and 13,018 hectares (44.0%) occurring in the Upper, Middle, and Lower Day zones, respectively (Figures 1, 2, and 3). SAV generally increased in each of the three zones from 1992. Decreases in some sections (e.g. Mid-Bay Island Complex, Upper Eastern Shore, and Western Shore) were offset by larger increases in other sections (e.g. Choptank River, Eastern Bay, and Chester River sections). SAV increased in abundance in all sections in the Lower Bay zone. In 1993, in the Upper Bay zone, 66.5% (1,777 hectares) of the SAV was located in the Susquehanna Flats (Section 1). Overall abundance and density of SAV was similar to the 1992 level'(1,792 hectares). In the Flats, 85.4% of all SAV beds were classified as very sparse in 1993 (0-10% coverage), while 7.7% of beds were classified as dense (70-100% coverage) (Figure 3). Myriophyllum spicalum, Heteranthera dubia, Vallisneria americana, Hydrilla verticillata, Ceratophyllum demersum, and Najas guadalupensis were the six species reported. In the Upper Eastern Shore (Section 2) there were 184 hectares of SAV in 1993 (99 hectares less than in 1992) located principally in the Elk and lower Sassafras rivers, with M spicatum and V. americana found most frequently, especially in the Elk River. Much of the difference from 1992 in the Upper Eastern Shore section was recorded from the Elk River. The Upper Western Shore (Section 3) had 80 hectares of SAV compared to 186 hectares recorded in 1992. SAV was reported from the Gunpowder River area including Dundee Creek; the lower Spesutie Narrows; the Mddle and Magothy rivers; and Romney and Delph creeks. SAV was noticeably reduced in Saltpeter Creek from 1992 and was absent from Seneca Creek in 1993. SAV was mapped in the Magothy River for the first time since it was last reported in 1978. Myriophyllum spicatum, Elodea canadensis, and 7imnichelhapalustris were frequently cited. In the Chester River (Section 4) SAV abundance (629 hectares) was up 374 hectares from 1992. SAV was most abundant adjacent to Eastern Neck, Eastern Neck Island, and in the lower Chester River, Ruppia maritima was most commonly cited. In 1993, 39.3% (5,467 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 a decrease of 527 hectares over 1992. In this zone, 21.4% (2972 hectares) of the SAV was present in the Middle Eastern Shore (Section 12), primarily in the Barren Island-Honga River area; the Big ix Susquehanna R. Uj Patapsco R.

SAV was much less abundant in the Barren Island area. No SAV was mapped from the Central Western Shore (Section 5) and Middle Western Shore (Section 9). SAV in the Patuxent River (Section 8) increased from 0 hectares in 1992 to 10 hectares in 1993. Citizens' surveys reported Z palustris and R maritima at numerous locations in the South and Severn rivers. Eleven species were reported in the Patuxent River. The Middle Bay zone also includes the entire Potomac River, where 2,820 hectares of SAV were present in 1993. SAV was concentrated in two distinct regions: 1) the Upper Potomac River (Section 11) with 2,363 hectares; and 2) the upper portion of the Lower Potomac River (Section 10) with 458 hectares, including Nanjemoy Creek and Port Tobacco River. Although the total abundance of SAV in the Upper Potomac section decreased from 1992 by 99 hectares, there was a notable increase in SAV in the Alexandria quadrangle. In particular, a large shoal area in the middle Potomac River, just above the large bed around the Woodrow Wilson Bridge, which had been previously unvegetated, supported sparse SAV for the first time since this survey was initiated. Ground truth data was reported by USGS and Citizens' surveys with 9 species reported: M spicalum, V. americana, H. verticillata, H. dubia, C demersum, Najas minor, Potamogelon pectinalus, Poiamogeton crispus, and N. guadalypensis. SAV in the lower Potomac River also decreased (113 hectares) in 1993. Ground truth data was reported by Citizens' and VIMS surveys with 4 species cited: Z. pahistris, P. crispus, R. maritima, and M. spicalum. SAV continued to increase in the Eastern Bay and Choptank River sections from 1992. SAV in the Eastern Bay (Section 6) increased IS' ) hectares from 1992 to a total of 73 7 hectares in 1993, while in the Choptank River (Section 7) it increased 809 hectares from 1992 to a total of 1,894 hectares in 1993. Most of the increase in the Eastern Bay occurred in Cox Creek, Crab Alley Bay, around Parson Island, and Piney Neck Point. In the Choptank River section, SAV beds were most abundant in Harris and Broad creeks and in Trippe Bay. Two species were reported from Section 6, with R. maritima most commonly cited. Three species were reported from Section 7, with R. maritima most commonly cited. Distribution and abundance of SAV in 1993, in the Lower Bay zone, were sin-dlar to 1992. In this zone, 48.4% (6,299 hectares) of the SAV was found in the Lower Eastern Shore (Section 14) around the Fox, Cedar, Webb, and Halftoon islands; and the mouths of major creeks (i.e. Cherrystone Inlet; Hunaars, Mattawoman, Nassawadox, Occohannock, Craddock, Pungoteague, Nandua, and Onancock creeks; and Beasley Bay). Along the western shore of the Chesapeake Bay, SAV was abundant in Mobjack Bay (Section 18) (14.2% of SAV in the Lower Bay zone), in the lower York River (Section 19) (6.5% 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 (15.9% of SAV in the Lower Bay zone). Sparse SAV was documented for a segment of the south shore of the York River, downstream from Yorktown, for the first time in over twenty years (Orth and Gordon, 197 5). There were 8 1 3 ) hectares of SAV mapped in the Reedville Region (Section 15) in 1993, a 4.5% increase over 1992. There were 431 hectares of SAV identified in 1993 in the New Point Comfort Region (Section 17), compared to 396 hectares in 1992. SAV abundance was up 23. 1% from 1992 in both the Piankatank and Rappahannock rivers (Section 16). The James River (Section 21) had 4 hectares of SAV in 1993. Zostera marina and R. maritima were the abundant species in this zone. xiii SAV in the Chincoteague Bay section increased in distribution with 3,576 hectares mapped in 1993 compared to 3,3)24 hectares in 1992. Most of the SAV in Chincoteague and Sinepuxent bays, which consisted mainly of Z marina and R. maritima, was located along the eastern side of the bay behind Assateague Island. Some small beds, consisting mainly of R. maritima, were located along the eastern side of Isle of Wight and Assawoman bays. xiv ACKNOWLEDGEMENTS We would like to gratefully acknowledge all federal and state agencies who financially supported this project: the U.

Xv 1993 SAV SPECIES The term "submerged aquatic vegetation" for the purpose of this report encompasses 20 taxa from 10 vascular macrophyte families and 3 taxa from I freshwater macrophytic algal family, the Characeae, but excludes all other algae, both benthic and planktonic, which occur in Chesapeake Bay and its tributaries (Appendix A). Although these other algae do constitute a portion of the SAV biomass in Chesapeake Bay and its 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 spicalum (Eurasian watermilfbil), Potamogeton pectinalus (sago pondweed), Potamogeton perfibliahis (redhead grass), Zannichelliapalustris (homed pondweed), Vallisneria americana (wild celery), Elodea canadensis (common elodea), Ceratophyllum demersum (coontail), and Na/as guadalupensis (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, 198-31). Ruppia maritima (widgeon grass) is tolerant of a wide range of salinities and is found from the bay mouth to the Susquehanna Flats. Approximately 13 other species are only occasionally found. When present, these species occur primarily in the middle and upper reaches of the bay and the tidal rivers (Appendix A). Hya@-illa 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 1993 in the Susquehanna River and 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. SAV 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 Chesapeake Bay, its tributaries, and Chincoteague Bay in 1993. There were 1, 500 photographs from 13 7 flight lines which were carefully examined to identify all SAV beds visible on the photography. 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 1993 was tabulated, placed onto the same 7.5 minute quadrangles, and entered into the SAV digital data base. AERIAL PHOTOGRAPHY The 19933 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 tens 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 137 flight lines covering 1,764 miles of shoreline and yielding 1,500 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 Unes were prioritized by sections. Flights were timed to occur dufing 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 guidefines assured acquisition of photography under nearly optimal conditions for detection of SAV, thus insuring accurate photointerpretation. 2 SUSQUEHANNA R 43 SUSQUEHANNA Qzmv 40 FLATS 44 47 51 t5 41 5 42 39 M B LTIMOR 37 3435 36 M 31 5 WASHINGT 21 2 > 7 C 127 28 X 20 28 2 5 27 21 19 25 18 rr 12 17 ISLE OF WIGHT BAY 6 ?C)TO)@f4o 62 15 16 4 cr) 122 C11 64 DELAWARE 33 73 13 10 7 --- MARYLAN .D ........ .- .." ------- 5 60 1 8 115 121 1 71 70 10 2 114 16 1@ 69 1 @11 4j 72 4 4 19 76 ,,@V78 3 0011 67 13 6 137 80 2 A 79 0 197 84 82- - 811-41D-@'@ 110 106 3 113 87A 85 87C 87D 138 88 86 -89 A 9 0 9 0) 9 C 95 104 00 98 117 0 20 1Q2 KILOMETER 10 Figure 4.

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 20' and 40' to minimize water surface ghtter. 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/fitra/focal length combination permitted 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 1993 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 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 1993 from aerial photography, 1993 ground truth information, and aerial site surveys.

Distortion-free, identical copies of these base maps were made at the same scale on stable transparent mylar using a contact diazo process. SAV beds from the 1993 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 printwrith 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 (Figure 6). 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 (10-4011/o); 3, moderate (40-70%); or 4, dense (70-100%). Either the entire bed or subsections within the bed were assigned a bed density number (I 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 further 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 AND QUALITY ASSURANCE PROCEDURES The perimeters of all SAV beds mapped from the aerial photography onto the diazo mylar copies were digitized in ARCANFO, using an AJtek Model 41 tablet, with a resolution of .00 1 inches (.00254 cm) and an accuracy of.005 inches (.0127 cm). The beds for each quadrangle were digitized twice into two separate ARCANFO coverages. Each coverage was plotted at an exact scale of 1:24,000 on translucent plotter paper and overlaid on the original mylar for visual checking. In instances where the digitized SAV bed boundaries did not correspond to the original, the bed was re- digitized. Once the SAV outlines on both coverages passed visual inspection, a bed-by-bed compajison of the areas (sq. meters) was made as an additional quality assurance check. Beds were rejected and redigitized if they were larger than I hectare and there was a difference of greater than 0. 1% area between the two coverages. The bed-by-bed comparison was usefW in identifying instances where SAV beds were incorrectly labelled, thus eliminating coding errors. 10 DENSITY CLASS -1- 5% VERY SPARSE 0-10% 15% -2- 25% SPARSE 10-40% 3 5 % 45% -3- MODERATE 40-70% 65% 75%0 So BU -4- 8,5%0 M H DENSE 70-100% 95% E PERCENT CROWN COVER Fiaure 6. Crown density scale used for estimating density of SAV beds from aerial photography. (Rows of squares with black and white patterns represent three different arrangements of vegetated cover for a given percentage.) M 11 SAV Prior to each digitization session, the Altek instrument was checked manually against a digitizing standard. This was accomplished by first securing a diazo mylar quadrangle with SAV polygons to the digitizing tablet. Then the mylar standard was secured to the same quadrangle and digitized. 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%, the maps were redigitized. In addition, visual checks were made with respect to the absolute location of the digitizing standard as secured to the map. 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. Standard operating procedures (SOPs) were developed to facilitate orderly and efficient processing of the 1993 SAV maps and the SAV computer files produced from them, and to comply with the need for consistency, quality assurance, and quality control. SOPs developed include: a detailed procedure for digitization of SAV maps; 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. CALCULATION OF 1993 SAV AREAS The SAV coverages in UTM ARCANFO Zone 18 format were used to calculate area in square meters for all SAV beds. These areas are reported as USGS 7.5 minute quadrangle section, and zone totals in the tables in the Results section. 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 Chesapeake Bay and tributaries has been organized into three zones as established by Orth and Moore (1982) and modified by Orth et al., (1989) (Figure 7). The Lower Bay zone is the area from the entrance of the bay to a line originating from Smith Point at the mouth of the Potomac River, extending 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. 12 1993 TABLE3 Area Descriptions for Each of the 21 Sections of the Chesapeake Bay SAV Study Area. Section 1. Susquehanna Flats - all areas between and including Spesutie Island and Turkey Point at the mouth of the Elk River to include the Northeast River. Section 2.

Section 20. Lower Western Shore - includes all areas south of Goodwin Island to Lynnhaven Inlet, including Broad Bay but not including the James River. Section 2 1. James River - all areas in the James River including the Chickahominy River. Sections 12, 13, 14, 18, 19, and 20 were given new boundaries for the 1987 report (Orth et al., 1989) which also changed the delineation of the three zones. These new boundaries were retained for the 1989, 1990, 1991, and 1992 reports (Orth and Nowak, 1990; Orth et al., 1991; Orth et al., 1992, Orth et al., 1993) and for this report.

Location of Chincoteague Bay and Chesapeake Bay with Upper, Middle, and Lower zones and 21 sections used for delineation of SAV distribution patterns. (See Table 3 and Appendix B for exact boundary positions.) 16 1993 The salinity within each zone roughly coincides with the major salinity zones of estuaries: polyhaline (18-25 '/oo), Lower zone; mesohaline (5-18 Voo), Mddle zone; ofigohatine (0.5-5 Voo), Upper zone. Although the rn@jor 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 (Figure 7, Table 3) for a more detailed discussion of SAV distribution. 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 1993 SAV distribution and abundance data were used for the 1987, 1989, 1990, 1991 and 1992 reports (Orth et al., 1989; Orth and Nowak, 1990, Orth et al., 199 1, Orth et al., 1992, Orth et al., 1993). Sections I through 4 are located in the Upper Bay zone; sections 5 through 13 are in the Middle Bay zone; and sections 14 through 21 are in the Lower Bay zone. SAV distribution in Chincoteague Bay is presented and discussed separately from Chesapeake Bay. Appendix B gives the latitude and longitude, in decimal degrees, of the boundary points of each Chesapeake Bay section and of Chincoteague Bay. 17 SAV 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 1993 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 Q 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 Appendix E. In Maryland, ground survey data were obtained in 1993 by VIMS, the USGS National Center, U.S. Fish and Wildlife Service, Patuxent River Park staff, and by the Citizens' volunteer survey. The USFWS contributed ground survey data for the Magothy and Chester rivers. The USGS National Center provided ground truth data for the Potomac River. Patuxent River ground survey data were obtained by the Maryland-National Capital Parks and Planning Commission Patuxent River Park staff. 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 1992 SAV maps to aid in the location of SAV beds, and data sheets for reporting visits to numerous sites around the bays. USFWS staff mapped the data on copies of 1992 SAV distribution maps (USGS 7.5 minute quads with 1992 SAV beds). These maps were supplied to VIMS SAV researchers and transferred to the 1993 SAV distribution maps reproduced in Appendix C. Data from the USFWS, Patuxent River Park staff, and the Citizens' surveys were compiled and tabulated by USFWS. This table became the basis of the much expanded table published in Appendix E. One 1993 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. 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 18 1993 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 1993 SAV bed location. This expanded ground survey table is presented in Appendix E. 19 SAV 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 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 1993. The 1993 SAV distribution data and species occurrences are first discussed relative to the Upper, Nfiddle, and Lower Bay zones. The 21 sections of the Chesapeake Bay, and Chincoteague Bay, are then discussed individually, and the data compared to results from the 1992 survey of SAV distribution and abundance (Orth, et al., 199-31). SAV is plotted for each section and for Chincoteague Bay in Figures 8 through 36. 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. 1993 SUMMARY In 1993, the Chesapeake Bay had 29,589 hectares of SAV, compared to 28,591 hectares in 1992, with 2,700 hectares (9.0%), 13,901 hectares (47.0%), and 13,018 hectares (44.0%) occurring in the Upper, Middle, and Lower Bay zones, respectively (Figures 1, 2, and 3). SAV generally increased in each of the three zones from 1992. Decreases in some sections (e.g. Mid-Bay Island Complex, Upper Eastern Shore, and Western Shore) were offset by larger increases in other sections (e.g. Choptank River, Eastern Bay, and Chester River sections). SAV increased in abundance in all sections in the Lower Bay zone. Upper Bay Zone In 1993, in the Upper Bay zone, 66.5% (1,777 hectares) of the SAV was located in the Susquehanna Flats (Section 1). Overall abundance and density of SAV was similar to the 1992 level (1,792 hectares). In the Flats, 85.4% of all SAV beds were classified as very sparse in 1993 (0-10% coverage), while 7.7% of beds were classified as dense (70-100% coverage) (Table 7; Figure 3). Myriophyllum spicatum, Heteranthera dubia, V americana, H. verticillata, C. demersum, and N. guadalupensis were the six species reported. In the Upper Eastern Shore (Section 2) there were 184 hectares of SAV in 1993 (99 hectares less than in 1992) located principally in the Elk and lower Sassafras rivers, with M spicatum and V americana found most frequently, especially in the Elk River. Much of the difference fi7om 1992 in the Upper Eastern Shore section was recorded from the 20 1993 TABLE4 Total Area of SAV in Hectares by USGS 7.5 Minute Quadrangles for 1992 and 1993.

The Upper Western Shore (Section 3) had 80 hectares of SAV compared to 186 hectares recorded in 1992. SAV was reported from the Gunpowder River area including Dundee Creek; the lower Spesutie Narrows; the Middle and Magothy rivers; and Romney and Delph creeks. SAV was noticeably reduced in Saltpeter Creek from 1992 and was absent from Seneca Creek in 1993. SAV was mapped in the Magothy River for the first time since it was last reported in 1978. Myriophyllum spicatum, E. canadensis, and Z palustris were frequently cited. In the Chester River (Section 4) SAV abundance (629 hectares) was up 374 hectares from 1992. SAV was most abundant adjacent to Eastern Neck, Eastern Neck Island, and in the lower Chester River. Ruppia marilima was most commonly cited. Middle Bay Zone In 1993, 39.3% (5,467 hectares) of the SAV in the NEddle Bay zone was found in the Md-Bay Island Complex (Section 13) which includes the broad shoal area between Smith and Tangier Islands. This is a decrease of 527 hectares over 1992. In this zone, 21.4% (2972 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. maritima reported most frequently. SAV was much less abundant in the Barren Island area. No SAV was mapped from the Central Western Shore (Section 5) and Middle Western Shore (Section 9). SAV in the Patuxent River (Section 8) increased from 0 hectares in 1992 to 10 hectares in 1993. Citizens' surveys reported Z palustris and R. maritima at numerous locations in the South and Severn rivers. Eleven species were reported in the Patuxent River. The Middle Bay zone also includes the entire Potomac River, where 2,820 hectares of SAV were present in 1993. SAV was concentrated in two distinct regions: 1) the Upper Potomac River (Section 11) with 2,363 hectares; and 2) the upper portion of the Lower Potomac River (Section 10) with 458 hectares, including Nanjemoy Creek and Port Tobacco River, Although the total abundance of SAV in the Upper Potomac section decreased from 1992 by 99 hectares, there was a notable increase in SAV in the Alexandria quadrangle. In particular, a large shoal area in the middle Potomac River, just above the large bed around the Woodrow Wilson Bridge, which had been previously unvegetated, supported sparse SAV for the first time since this survey was initiated. Ground truth data was reported by USGS and Citizens' surveys with 9 species reported: M spicatum, V conericana, H. verticillata, H. duhia, C. demersum, Najas minor, P. pectinatus, P. crispus, and N. guadalupensis. SAV in the lower Potomac River also decreased (113 hectares) in 1993. Ground truth data was reported by Citizens@ and VIMS surveys with 4 species cited: Z palustris, P. crispus, )Z maritima, and M spicatum. SAV continued to increase in the Eastern Bay and Choptank River sections from 1992. SAV in the Eastern Bay (Section 6) increased 183 hectares from 1992 to a total of 737 hectares in 1993, while in the Choptank River (Section 7) it increased 809 hectares from 1992 to a total of 1,894 hectares in 1993. Most of the increase in the Eastern Bay occurred in Cox Creek, Crab Alley Bay, around Parson Island, and Piney Neck Point. In the Choptank River section, SAV 44 1993 beds were most abundant in Harris and Broad creeks and in Trippe Bay. Two species were reported from Section 6, with R. maritima most commonly cited. Three species were reported from Section 7, with R. maritima most commonly cited. Lower Bay Zone Distribution and abundance of SAV in 1993, in the Lower Bay zone, were similar to 1992. In this zone, 48.4% (6,299 hectares) of the SAV was found in the Lower Eastern Shore (Section 14) around the Fox, Cedar, Webb, and Halfffioon islands; and the mouths of major creeks (i.e. Cherrystone Inlet; Hungars, Mattawoman, Nassawadox, Occohannock, Craddock, Pungoteague, Nandua, and Onancock creeks; and Beasley Bay). Along the western shore of the Chesapeake Bay, SAV was abundant in Mobjack Bay (Section 18) (14.2% of SAV in the Lower Bay zone), in the lower York River (Section 19) (6.5% 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 (15.9% of SAV in the Lower Bay zone). Sparse SAV was documented for a segment of the south shore of the York River, downstream from Yorktown, for the first time in over twenty years (Orth and Gordon, 1975). There were 813 hectares of SAV mapped in the Reedville Region (Section 15) in 1993, a 4.5 % increase over 1992. There were 4' ) I hectares of SAV identified in 1993 in the New Point Comfort Region (Section 17), compared to 396 hectares in 1992. SAV abundance was up 23. 1 % from 1992 in both the Piankatank and Rappahannock rivers (Section 16). The James River (Section 21) had 4 hectares of SAV in 1993. Zostera marina and R. maritima were the abundant species in this zone. Chincoteague Bay SAV in the Chincoteague Bay section increased in distribution with 3,576 hectares mapped in 1993 compared to 3,324 hectares in 1992. Most of the SAV in Chincoteague and Sinepuxent bays, which consisted mainly of Z maliza and R. maritima, was located along the eastern side of the bay behind Assateague Island. Some small beds, consisting mainly of R. maritima, were located along the eastern side of Isle of Wight and Assawoman bays. 45 SAV DISCUSSION OF SECTIONS ARRANGED WITHIN ZONES Upper Bay Zone 1. Susquehanna Flats There were 1,777 hectares of SAV in the Susquehanna Flats section in 1993 (Tables 4-7; Figure 8; Appendix C, Maps 2, 3, 8 and 9), compared to 1, 792 hectares mapped in 1992. In this section 7.7% of the total coverage of SAV in this section was dense (class 4), 2.6% was moderate (class 3), 4.2% was sparse (class 2), and 85.4% was very sparse (class 1) (Table 7; Figure 3). SAV beds were located principally in two main areas: 1) sparse to dense ffinging beds in the Susquehanna River consisting primarily of M. spicatum, with H. dubia, V americana, H. verlicillata, and C demermim fforn Robert Island to the river mouth at Havre de Grace on the west side, to Stump Point at the mouth of NO Creek on the east side, and in Mill Creek, Furnace Bay, Baker Cove, and at High Point; and 2) a large area of very sparse SAV located in the broad shoal area at the river mouth. This broad shoal area continues to consist of small patches ofM. spicatum. Additionally, the Citizens' survey reported H. verficillata. In addition, SAV beds were again mapped in Spesutie Narrows where most SAV is found as small, fiinging beds ofM. spicatum and H. verficillata. A total of six species (M. spicatum, H. dubia, V americana, H. verticillata, C demersum, N. guadahipensis) have been reported on Maps 2, 3, and 9 (Appendix C), either by Stan Kollar of Harford Community College or the Citizens' Survey. 2. Upper Eastern Shore There were 184 hectares of SAV mapped for the Upper Eastern Shore section in 1993 (Tables 4-7; Figure 9; Appendix C, Maps 4, 9, 10, 15, 16, and 17), compared to 283 hectares mapped for 1992. In this section 2.1% of the total coverage of SAV was dense (class 4), 16.8% was moderate (class 3), 17.4% was sparse (class 2), and 63.7% was very sparse (class 1) (Table 7; Figure 3). Principal locations of beds were in the Elk River and the lower Sassafras River. Very little SAV was mapped in the Bohemia River or along the mainstern of the bay from Still Pond to Swan Point. Much of the decrease was recorded in the Elk River. Ground survey data from Stan Kollar and the Citizens' survey reported 5 species in this section (Appendix C, Maps 4, 9, 10, 16, and 17), with M spicatum and V americana found most frequently. Heteranthera dubia, P. crispus, P. pectinalus, and an unidentified species were also reported in the Elk River. 3.

Of the total coverage of SAV in this section 1.5% was dense (class 4), 31.9% was moderate (class 3), and 62.2% was sparse (class 2), and 4.5% was very sparse (Table 7; Figure 3). SAV beds were located in Romney, Little Romney, and Delph creeks, the lower Spesutie Narrows, the Gunpowder River area, including Dundee Creek, and the Magothy and Middle rivers. SAV was noticeably reduced in Saltpeter Creek and was absent in Seneca Creek. SAV was mapped for the first time in the Magothy River since 1978. As in 1992, no SAV was reported in the Back, Patapsco, and Bush rivers. Ground survey data from the Citizens' survey and the U.S. Fish and Wildlife Service reported I I species in this section (Appendix C, Maps 9, 13, 14, 23, and 24). Myriophyllum spicalum, E. canadensis, and Z palustris were found most frequently. Vallisneria americana, P. crispus, P. pectinatus, P. perfolialus, R. maritima, Najasflexifis, Najas spp., and C. demersum were reported less frequently. 4. Chester River There were 629 hectares of SAV in the Chester River section in 1993 (Tables 4-7; Figure 11; Appendix C, Maps 20, 21, 26, and 33), compared to 255 hectares in 1992. In this section, 28.8% of the total coverage of SAV was dense (class 4), 35.4% was moderate (class 3), 21.6% was sparse (class 2), and 14. 1 % was very sparse (class 1) (Table 7- Figure 3). This is a notable increase since 1991, when only 57 hectares were reported. 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; in Grays Inn, Langford, and Queenstown creeks, tributaries entering the Chester River. Rock Hall Harbor; the Haven; and Swan, Langford, and Huntingfield creeks, located above Eastern Neck on the Chesapeake Bay, supported the remaining SAV beds in this section. Eight species of SAV were reported from this section by Citizens', U.S. Fish and Wildlife Service, and VIMS surveys in 1993: Potamogeton perfoliatus, Z palustris, R. maritima, M. spicatum, C demersum, E. canadensis, N. spp., and N. flexilis (Appendix C, Maps 26 and 33). Middle Bay Zone 5. Central Western Shore There was no SAV observed from the aerial photography in the Central Western Shore section in 1993 (Tables 4-7; Figure 12). This was the same as 1992. Citizens' surveys found Z palustris and R. maritima at numerous locations in the Severn and South rivers (Appendix C, Maps 30 and 3 1) as well as Potamogelon pusillus at Lake Ogleton. 49 006 007 08 009 _M3 012 Middle R. 4 Back Rim r 014 018 019 0 2 GY Mai. 024 025 023 Figure 10.

Eastern Bay There were 737 hectares of SAV identified from the Eastern Bay section in 1993 (Tables 4-7; Figure 13; Appendix C, Maps 32, 33, 36, and 37), compared to 554 hectares reported in 1992, a 33. 1% increase. This is the second year in a row that SAV has increased in this area. Only 68 hectares were reported in 1991. In this section, 2.2% of the total coverage of SAV in this section was dense (class 4), 17. 1 % was moderate (class 3), 11.8% was sparse (class 2), and 68.9% was very sparse (class 1) (Table 7; Figure 3). Most of the SAV was found in the lower Mies River; 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 Harbor Cove and Tilghman Point on Eastern Bay. Only two species of SAV were reported from this section by Citizens' and VIMS surveys: Z palustris and R. maritima, (Appendix C, Maps 3 2, 3 3, and 3 6) with R. maritima most commonly cited. 7. Choptank River There were 1894 hectares of SAV observed in the Choptank River section in 1993 (Tables 4-7; Figures 14 and 15; Appendix C, Maps 36, 37, 43, 44, 51, 52, 53, and 62), compared to 1085 hectares in 1992. This was an increase of 74.5%. In this section, 3.3% of the total coverage of SAV was dense (class 4), 19.2% was moderate (class 3), 59. 1% was sparse (class 2), and 18.3% was very sparse (class 1) (Table 7; Figure 3). In the Choptank River, SAV was found in moderate to sparse beds in Blackwalnut Cove at the southern tip of Tilghman Island: Harris, Broad, San Domingo, Edge, Irish, and Chapel creeks; the Tred Avon River; Dickinson Bay; and Castle Haven Point. Moderate to sparse beds were also found in Trippe Bay; the lower Choptank River, including James Island, Hills Point; Oyster, Cators, and Hooper coves; and Slaughter, Brooks, Hudson, and Back creeks. Three species of SAV were reported from this section by Citizens' and VIMS surveys: Z palustris, It maritima, P. perfoliatus, and an unidentified species (Appendix C, Maps 36, 37, 43, 44, 51, 52, and 53) with R. maritima most commonly cited. 8. Patuxent River There were 10 hectares of SAV observed in 1993 in the Patuxent River section (Tables 4-7; Figures 16 and 17, Appendix C, Maps 41 and 7 1), compared to zero hectares in 1992. One bed was located in the upper Patuxent River where many of the Citizens' reports were located, while a second bed was noted at the mouth of the river between Solomons Island and Drum Point. In this section, 10.2% of the total coverage was moderate (class 3), while 89.8% was sparse (class 2). A total of eleven species were reported in this section. The Citizens' survey reported ten species occurring primarily in the marsh creeks in the upper portions of the Patuxent River (Appendix C, Maps 41, 49, and 159): E canadensis, C. demersum, V cunericana, Z palustris, N. guadalupensis, N. minor, P. crispus, P. pusillus, H. verticillata, and Potamogeton epihydrus.

Middle Western Shore There were no SAV beds identified in the Middle Western Shore section in 1993 (Tables 4-7- Figure 18) the same as in 1992. 10. Lower Potomac River There were 458 hectares of SAV identified in the Lower Potomac River section as indicated on the 1993 aerial photography (Tables 4-7; Figures 19, 20, and 21; Appendix C, Maps 56, 57, 58, 65, 66, 67, 80, 89, and 162), compared to 571 hectares reported in 1992 with most of the changes occurring in Nanjemoy Creek. In this section, 52.2% of the total coverage of SAV was dense (class 4), 20.7% was moderate (class 3), 25.0% was sparse (class 2), and 2.0% was very sparse (class 1) (Table 7; Figure 3). Most of the SAV occurred along Nanjemoy Creek and Port Tobacco River, as well as along the shoreline adjacent to these two creeks, and fringing the eastern side of Mathias Point Neck to an areajust below the Route 301 Bridge (Harry Nice Memorial Bridge). Several small beds were observed in Machodoc, Rosier, and Cuckold creeks; the St. Marys River; in Calvert Bay at the mouth of Smith Creek; Lloyd Point; above Lower Cedar Point; and in the upper Wicomico River. Ground survey data was available from Citizens' and VIMS surveys for Maps 68, 76, 78, and 80 (Appendix Q. Zannichelliapalustris and P. crispus were reported from the Lower Machodoc Creek (Appendix C, Map 78). Zannichellia palustris was found in Neale Sound off the Wicomico River (Appendix C, Map 68). Ruppia maritima was reported from the St. Marys River (Appendix C, Map 80). Myriophyllum spicatum was reported in Popes Creek (Appendix C, Map 76). 11. Upper Potomac River There were 2,363 hectares of SAV mapped in the Upper Potomac River section (Tables 4-7; Figures 22, 23, and 24; Appendix C, Maps 28, 29, 34, 39, 40, 47, 48, 55, 64, 65, and 161) in 1993, compared to 2,462 hectares reported in 1992, a decrease of 4%. A total of 80.9% of the SAV beds were densely vegetated (class 4), 10.3% was moderate (class 3), 5. 1 % was sparse (class 2), and 3.7% was very sparse (class 1) (Table 7- Figure 3). Although there was an overall reduction in $AV abundance, there was a notable change in SAV distribution in the Alexandria quadrangle (Appendix C,.Map 34). An expansive shoal area in the middle of the river, just above the large dense bed surrounding the Woodrow Wilson Bridge, supported sparse SAV (bed FBI) for the first time in '1993. The western side of the mainstem Potomac River, from the Woodrow Wilson Bridge to Occoquan Bay remains very sparsely vegetated.

Middle Eastern Shore There were 2,972 hectares of SAV identified in the Middle Eastern Shore section (Tables 4-7; Figure 25; Appendix C, Maps 63, 72, 73, 74, 82, 83, 84, 85, 92, 93, 100, and 101) in 1993, compared to 3,047 hectares reported in 1992. In this section, 17.6% of the SAV was dense (class 4), 36.2% moderate (class 3), 40.8% sparse (class 2), and 5.4% 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 Annernessex rivers. SAV abundance declined in the Barren Island area from 1992 (Barren Island quadrangle - 434 hectares in 1992 to 206 hectares in 1993), while increasing in the Honga River area (Honga quadrangle - 1,327 hectares in 1992 to 1340 hectares in 1993; Wingate quadrangle - 481 hectares in 1992 to 541 hectares in 1993; Golden Hill quadrangle - 29 hectares in 1992 to 65 hectares in 1993). No SAV beds were observed in Fishing or Monie bays, and in the Nanticoke and Wicomico rivers. Ground survey data were available for this section in 1993 from Citizens'and VIMS surveys (Appendix C, Maps 72, 73, 74, 84, 100, and 101). Ruppia maritima and Z marina was reported most frequently. 13. Mid-Bay Island Complex There were 5,467 hectares of SAV mapped in the Mid-Bay Island Complex in 1993 (Tables 4-7; Figure 26; Appendix C, Maps 83, 91, 92, 99, 100, 107, and 179), compared to 5,994 hectares reported in 1992, an 8.8% decrease, and with declines in abundance noted in all quadrangles. This section contains 18.5% of the SAV in the entire Chesapeake Bay, slightly less than the 21.0% in 1992. However, the density of SAV has decreased since 1992. In 1993, 37.1% of the SAV within this section was in dense and moderate beds (classes 3 and 4), compared to 70.8% in 1992. In the remaining classes, 55.4% was sparse (class 2), compared to 27. 1% in 1992, and 7.4% was very sparse (class 1) compared to 2. 1 % in 1992 (Table 7; Figure 3). SAV is present mainly in dense to moderate beds along the broad, expansive shoal area between Tangier Island and Smith Island; the eastern side of Tangier Island; the western side of Goose Island; Mailboat Harbor, and on the shoals and in the coves adjacent to Bloodsworth, South Marsh, Holland, Adam, and Spring islands. The Citizens' ground survey reported R. maritima, and Z. marina (Appendix C, Map 99) for this section in 1993. Lower Bay Zone 14. Lower Eastern Shore There were 6,299 hectares of SAV observed in the Lower Eastern Shore section in 1993 (Figure 27; 67 hman Isfand 054 063 062 163 074 4- 164 072 081 073 hill. 083 084 gomlte ]30 Bloodswc rth 085 Island 082 093 Sou th Marsh island 092 S B@gA Cd r L We St, Oh Island Ann mese R er 100 0 101 Figure 25.

In this section 33.9% of the total SAV was dense (class 4), 16.0% was moderate (class 3), 39.3% was sparse (class 2), and 10.9% 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, Nassawadox, Mattawoman, Occohannock, Craddock, Pungoteague, Onancock, Nandua, and Chesconessex creeks. Large, dense beds also occur at the Big Marsh area near Chesconessex Creek, at Webb and Halfinoon islands off the mouth of Deep Creek, and on the large shoal area on the eastern side of the Fox and Cedar islands. SAV beds also were mapped along Ware Point Marsh and around Beasley Bay in the Pocomoke Sound. There was no SAV from Elliots Creek, just below Cape Charles, to Fishermans Island at the mouth of Chesapeake Bay. Ground survey data were limited in this section. Citizens' and VIMS surveys reported R. maritima and Z. marina from this section (Appendix C, Maps 100, 10 1, 114, 124, and 133). 15. Reedville Region There were 813 hectares of SAV identified in the Reedville Region in 1993 (Tables 4-7; Figure 28; Appendix C, Maps 106 and 112), compared to 778 hectares reported in 1992. In this section, 20. 1% of the total coverage of SAV was dense (class 4), 22.2% was moderate (class 3), 42.2% was sparse (class 2), and 15.6% was very sparse (class 1) (Table 7; Figure 3). Most beds were found in Little, Fleets, and Ingram bays; Dymer, Indian, Dividing, Ball, and Cloverdale creeks; Dameron Marsh; and adjacent to Fleeton Point. Zostera marina and R. maritima were the two species identified by Citizens' surveys (Appendix C, Maps 106 and 112). 16. Rappahannock River Complex There were 722 hectares of SAV observed in the Rappahannock River Complex in 1993 (Tables 4-7; Figure 29; Appendix C, Maps I 11, 117, 118, and 123), compared to 5 8 7 hectares reported in 1992. In this section 8.0% of the total coverage of SAV was dense (class 4), 22.3% was moderate (class 3), 60.4% was sparse (class 2), and 9.2% was very sparse (class 1) (Table 7; Figure 3). SAV beds were present in the Corrotoman River; along the north shore of the Rappahannock River, from the Corrotoman River to Windmill Point, Milford Haven, the lower Piankatank River; and from Ginney and Horse points to Gwynns Island. SAV beds have declined in the area between Carters Creek and the mouth of the Corrotoman River. The large SAV bed adjacent to Windmill Point that has been slowly expanding naturally since 1989 (contiguous beds BB2, CB 1, DB4; Appendices C and D, Map 118), now covers an area of 44 hectares, up from 2 8 hectares in 1992, with both Z marina and R. maritima present. SAV beds are abundant in Milford Haven, but are principally located along the north shore with both Z marina and R. maritima present. Ruppia maritima and Z marina were reported from ground surveys by VIMS staff and Citizens' surveys of S AV in Maps I 11, 118, and 123 (Appendix Q. 71 097 Creat 098 00 wt Fleeion Pt.

In this section 16.3% of the total coverage of SAV was dense (class 4), 57.4% was moderate (class 3), 18.5% was sparse (class 2), and 7.8% was very sparse (class 1) (Table 7; Figure 3). SAV beds were present from New Point Comfort just north of Horn Harbor at Potato Neck. SAV beds were also present at Winter Harbor. There was no ground truth data reported for this section. 18. Mobjack Bay Complex The Mobjack Bay Complex contained 1,843 hectares of SAV in 1993 (Tables 4-7; Figure 31; Appendix C, Maps 122, 123, 13 1, and 132), compared to 1,818 hectares reported in 1992. SAV beds were abundant along the entire shoreline of Mobjack Bay, as well as in the lower reaches of the four tributaries: Severn, Ware, North, and East rivers. 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. 1% of the total coverage of SAV was dense (class 4), 9.8% was moderate (class 3), 16.0% was sparse (class 2), and 4.2% was very sparse (class 1) (Table 7; Figure 3). Zostera marina and R. maritima were reported by Citizens'and VIMS surveys from Maps 122, 13 1, and 132 (Appendix Q. 19. York River There were 841 hectares of SAV observed in the York River section in 1993 (Tables 4-7; Figure 32; Appendix C, Maps 131, 132, 139, and 140), compared to 830 hectares reported in 1992. In this section 82.3% of the total coverage is classified as dense (class 4), while 0.0% was moderately dense- (class 3), 16. 1 % was sparse (class 2), and 1.6% was very sparse (class 1) (Table 7; Figure 3). Ground survey information was available for Maps 131, 132, 139, and 140 (Appendix Q from VIMS and Citizens! 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 and on the south shore adjacent to Goodwin Island. SAV beds were absent upstream of Gloucester Point along the north shore except for one small bed (Appendix C, Map 139, bed FAI) of Z marina near Gloucester Point, a result of a VIMS transplanting project using seeds in 1989, 1990, and 1991. SAV was documented for the first time since 1971 along the south shore from Yorktown to the Coast Guard pier (Orth and Gordon, 1975). These two very sparse beds (Appendix C, Map 140, beds AB I and BB I) consisted of small patches of Z marina. These patches were most likely the result of seed recruitment in the spring of 1991 from SAV beds downriver on the south shore (Goodwin Island), or along the north shore directly across the river. This conclusion is based upon an understanding of the reproductive biology of Z marina, which produces reproductive shoots in the second year of growth. These patches were too small in 1992 to have been documented by aerial photography.

Zostera marina was transplanted in the form of whole plants to the following sites: along the north shore at Claybank, and Mumford and Catlett Islands; and along the south shore at Yorktown. The transplanting effort was conducted by VIMS staff during the fall of 1992. Transplants remained .present through the summer of 1993. By the late summer of 1993, transplants survived at the Mumford Island and Yorktown sites, but did not survive at the Catlett Island or Clay Bank sites. 20. Lower Western Shore There were 2,066 hectares of SAV mapped in the Lower Western Shore section in 1992 (Tables 4-7; Figure 33; Appendix C, Maps 140, 141, 147, and 152), compared to 2,029 hectares reported in 1992. In this section 44.0% of the total coverage was mapped as dense (class 4), 27.5% as moderate (class 3), 13.9% as sparse (class 2), and 14.6% as very sparse (class 1) (Table 7; Figure 3). SAV was mapped in Broad Bay; Back River, including the lower Northwest Branch; the lower Poquoson River-, the mouth of the Poquoson River off Pasture and Hunts Neck; the lower Chisman Creek; 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 Branch of Back River; in Back Creek; or from Northend Point to Old Point Comfort. Ground surveys by Citizens' and VIMS (Appendix C, Maps 140 and 152) reported both Z marina and R. maritima. 2 1. James River There were 4 hectares of SAV in the mainstern of the James River in 1993 (Tables 4-7; Figures 34 and 3 5; Appendix C, Map 147), compared to 3.5 hectares in 1992. This single, very dense bed, (class 4) (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, and continues to remain the only SAV detected bed in the James River. Chincoteague Bay There were 3,576 hectares of SAV identified from the Eastern Shore of Virginia and Maryland in 1993. Chincoteague and Sinepuxent bays had 3556 hectares, and a small amount (20.35 hectares) was present in Isle of Wight and Assawoman bays (Tables 4-7; Figure 36; Appendix C, Maps 166, 167, 168, 170, 172, 173, 174, and 175), compared to 3,324 hectares reported in 1992. In this section 54. 1% of the total coverage was mapped as dense (class 4), 16.9% as moderate (class 3), 26.3% as sparse (class 2), and 2.6% as very sparse (class 1) (Table 7; Figure 3). The Citizens' survey found both Z marina and R. maritima throughout Chincoteague and Sinepuxent bays, as well as Assawoman bays (Appendix C, Maps 166, 167, 168, 170, 172, 173, and 175). 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 78 r 132 177 133 p,@j)e'T 141 142 q Drum lsl:Lnd Flats 140 6 146 Fisherman Island 147 149 150 151 Cape QD @1101 0 152 Henry CQ James Broad Bay, 156 157 @S n177 132 @+-e 1\42 Figure 33.
