SAV bed perimeter inforrmation was digitized and stored in a computerized data base. Ground truth information was obtained from the U. S. Geological Survey (USGS), the U. S. Fish and Wildlife Service (USFWS), the University of Maryland Horn Point Environmental Laboratories, Harford Community College and the College of William and Mary's Virginia Institute of Marine Science/School of Marine Science. Citizen support via the U. S. Fish and Wildlife Service and Chesapeake Bay Foundation, as well as the Maryland Charterboat Association via the Maryland Department of Natural Resources Watermen's Assistance Program, provided additional ground truth information. In 1989 the Chesapeake Bay had 24,134 hectares of SAV with 2,458 (10%), 11,507 (48%) and 10,169 (42%) hectares occurring in the Upper, Middle and Lower Bay zones, respectively (Figs. I and 2). Seventy-nine percent (1,945 hectares) of the SAV in the Upper Bay zone was located in the Susquehanna Flats section (Fig. 3, Section 1). Nine species of SAV were documented by ground truth surveys in this section, with Myriophyllum spicatum being dominant. Hydrilla verticillata, a recently introduced exotic species, was also found in the Flats but occurred in small isolated beds. Total hectares of SAV were reduced from that in 1987 in the Susquehanna Flats section and beds were generally much less dense. Ninety-five percent of all SAV beds were classified as very sparse (0-10% coverage) and no beds were classified as dense (70-100% coverage). The Upper Eastern Shore section (Fig. 3, Section 2) had 308 hectares SAV located principally in the Elk and lower Sassafras Rivers, Swan, Stillpond and Churn Creeks with many of the same species being reported as in the Susquehanna Flats section. The Upper Western Shore section (Fig. 3, Section 3) had 38 hectares SAV which was concentrated in Saltpeter and Seneca Creeks with M. spicatum and Vallisneria americana being most abundant. The Chester River section (Fig. 3, Section 4) had 167 hectares SAV which was most abundant adjacent to Eastern Neck and Eastern Neck Island, and in the lower Chester River. In this region Ruppia maritima was the most abundant of six species which were reported. Forty-five percent (5,196 hectares) of the SAV in the Middle Bay zone was found in the broad shoal area between Smith and Tangier islands in the Mid-Bay Island Complex (Tangier, Smith, Southmarsh and Bloodsworth Islands - Fig. 3, Section 13) where R. maritima and Zostera marina were present. Seventeen percent (1,998 hectares) of the SAV was present in the Middle Eastern Shore section (Fig. 3, Section 12) primarily in the Barren Island-Honga River area, the Big and Little Annemessex Rivers, and the lower section of the Manokin River. Ruppia maritima was the dominant species reported for this area. Little or no SAV was mapped or reported from the Central Western Shore, Middle Western Shore and Patuxent River sections (Fig 3, Sections 5, 9 and 8, respectively). The Middle Bay zone also includes the entire Potomac River where 2,614 hectares of SAV were present in 1989. The Upper Potomac River section, including the tidal freshwater region (Fig. 3, Section 11) had 1,998 hectares SAV with H. verticillata remaining the numerically vi dominant species. Eight other species were recorded from the USGS and Citizen's surveys. The Lower Potomac River section (Fig. 3, Section 10) had 616 hectares SAV with V. americana and M. spicatum being the most frequently occurring species. Although the total abundance of SAV in the upper Potomac River section increased from the 1987 level of 1,665 hectares, many of the very dense beds declined from the Woodrow Wilson bridge to just below Piscataway Cree'k. This decline was offset by large increases in SAV along both shores from Quantico Cree'k to Aquia Creek. SAV was abundant throughout the entire Lower Bay zone except for the James River. Forty-five percent of SAV in the Lower Bay zone was found in the Lower Eastern Shore section (Fig. 3, Section 14) around the Fox Islands and the mnouths of major creeks (i.e. Cherrystone Inlet, Hunga-rs Creek, Mattawoman Creek, Occahannock Creek, Craddock Creek, Pungoteague Creek and Onancock. Creek). Along the western shore SAV was abundant in Mobjack Bay, the Lower York River, Back River and the Drum Island Flats area adjacent to Plum Tree Island. Both R. maritima and Z. marina were abundant throughout the Lower Bay zone. Rusppia maritima continued to increase in abundance in both the Piankatank and Rappahannock rivers while Z. marina was present at several sites in both rivers resulting from previously successful transplant efforts. There were 2,310 hectares SAV in Chincoteague Bay in 1989 similar to 2,310 hectares in 1987. All of the SAV consisted of R. mnaritima and Z. marina which was located along the eastern side of the bay behind Assateague Island. vii 3940.0 I I I I I I sUSQUEHANNA R .

The recent signing of an SAV management policy by the govemnors of Virginia, Maryland, and Pennsylvania, the mayor of Washington, D. C., the EPA Administrator, and the Chesapeake Bay Commission Chairman (CEC, 1989), and the drafting of an SAV implementation plan for this baywide policy (CEC, 1990), indicate the commitment of the bay community to preserving, protecting, and enhancing these important systems. Monitoring of this resource on an annual basis, one aspect supported by the SAV policy, has revealed the dramatic changes occurring with SAV and has served to provide scientists and managers with a synoptic overview of the current abundance on a baywide basis. SAV communities in the entire Chesapeake Bay and tributaries have been photog-raphed, mapped and the areas of the beds digitized in 1978, 1984, 1985, 1986, 1987, and 1989 while portions of the upper bay were mapped and digitized in 1979 and the lower bay was mapped and digitized in 1980 and 1981 (Orth et al., 1979; Anderson and Macomber, 1980; Orth et al., 1985, 1986, 1987, and 1989). The bay shoreline was photographed in 1988, but was not mapped; sections of the lower bay were mapped and digitized in 1971 and 1974. Numerous SAV ground surveys have been conducted but most have been limited to specific sections. No one ground survey has delineated baywide SAV patterns. Aerial photography has proved to be a useful tool in examining SAV distribution patterns and, when combined with appropriate ground data, has provided an accurate, synoptic picture of baywide SAV distribution. The goal of the 1989 work was to continue the annual monitoring of SAV on a baywide basis using aerial photographic methods with appropriate ground truth to substantiate presence or absence of SAV in particular sections. I SAV SPECIES The termn 'submerged aquatic vegetation' for the purpose of this report encompasses 18 taxa from 10 vascular macrophyte families and 3 taxa from 1 freshwater macrophytic algal family, the Characeae, but excludes all other algae, both benthic and planktonic, which occur in the Chesapeake Bay and tributaries (Appendix A). For instance, benthic marine algae, including many macrophytes, sometimes co-occur in the same beds with vascular plants, even as epiphytes on vascular plants (Humm, 1979). Although outside the scope of this study, the algal component does constitute a portion of the SAV biomass in the Chesapeake Bay and tributaries. However, except for the Characeae, this study has not attempted to identifyr, delineate or discuss the algal component of the vegetation nor its relative importance in the flora. Ten species of submerged aquatic vegetation exclusive of the algae 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 pal ustris (horned pondweed), Vallisneria americana (wild celery), Elodea canadensis (common elodea), Ceratophylium demersum (coontail) and Najas 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, 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 eleven 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). Hydrilia 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 1989 in the Susquehanna Flats where its growth has not been as widespread as in the Potomac River (Kollar, pers. comm.). 2 METHODS Introduction Black and white aerial photography at a scale of 1:24,000 was the principal source of information used to assess the distribution and abundance of SAV in the Chesapeake Bay, its tributaries, and Chincoteague Bay in 1989. SAV beds mapped from photographs onto USGS 7.5 minute topographic quadrangles were then digitized, providing a digital data base for analysis of bed area and location. Ground truth information collected in 1989 was mapped onto the same topographic quadrangles. Aerial Photography The 1989 SAV 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 the Air Photographics' Piper Aztec, a twin engine reconnaissance aircraft. Photography was acquired at app-roximately 12,000 feet altitude, yielding a 1:24,000 photographic scale. Flight lines for photography, which were drawn on 1:250,000 scale USGS maps, 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). Flightlines also included land features that are necessary as control points for accurate mapping (Fig. 4). Sections of the upper Rappahannock, upper York and most of the James Rivers were not flown because the historical absence of SAV in these areas. Flight lines were prioritized by major sections. Dates of flight windows for aerial photography were timed to occur at peak standing crop of species known to occur in the sections. In addition, specific areas with significant coverage were given priority. Prior documentation and approval by the funding agencies was required to extend dates of flight windows if necessary. Actual dates of acquisition of photography are noted on each quadrangle map in Appendix C. General guidelines for mission planning and execution (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 optiimal conditions for detection of SAV, thus insuring accurate photo interpretation. Quality assurance and calibration procedures were consistently followed. The altimeter was calibrated by the Federal Aviation Administration annually. Photographic settings were selected with an automatic exposure control. Sun angle was measured with an indicator on the plane. Flight lines were plotted on 1:250,000 scale maps to allow for 3 121- Figure 4. Map of the Chesapeake Bay, its tributaries and Chincoteague Bay with approximate locations of flight lines for 1989 SAV photography. 4 Table I Guidelines Followed During Acquisition Of Aerial Photographs. 1. 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 delieation 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 minimnize imnage 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 maximnum 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 combinatio-n pe-rmitted resolution and identification of one square meter area of SAV (surface). 8. Plotting - Each flight line included sufficient identifiable land area to assure accurate plotting of grass beds. 5 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 to produce two foot resolution. Wind speed was monitored hourly from the flight service available in the region. Under normal operating conditions, flights were usually conducted under wind speeds less than 10 mph. (Above this, wind generated waves stir the bottom sediments which can easily obscure SAV beds in less than one hour.) Pilot experience determined what acceptable level of turbidity would insure complete delineation of SAV beds. At low tide the pilot should have been able to distinguish bottom features such as SAV or algae. When turbid conditions prevailed photography did not commence. Cloud cover did not exceed 5% of the area covered by the camera frame. Determination of cloud cover was based on pilot experience. Records of this parameter were kept in a flight notebook. Every attempt was made to acquire photographs with no cloud cover below 12,000 feet. A thin haze layer above 12,000 feet was generally acceptable. Experience has shown that the optimal conditions given above generally occur two to three days following passage of a cold front when winds have shifted from north-northwest to south and moderated to less than 10 mph. Where possible, and within the guidelines given for prioritizing and executing the photography, flights were planned to coincide with these atmospheric conditions. Exposed film was processed by Air Photographics. A contact print was produced for each exposed frame. Each photograph was labeled with date of acquisition as well as flight line number. Film and photographs were stored under appropriate environmental conditions to prevent degradation of the product. Mapping Process This study utilized USGS 7.5 minute topographic quadrangle maps as a basis for mapping SAV beds from aerial photography, for digitizing the SAV beds, and for compiling SAV bed area measurements. Figure 5 gives locations of topographic 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. Photo-interpretation to identifyr and delineate SAV beds utilized all available information including knowledge of aquatic grass signatures on film, distribution of SAV in 1989 from aerial photography, 1989 ground truth informnation, and aerial site surveys. USGS-published 7.5 minute topograp'hic quadrangle masters (1:24,000 scale) printed by the Mid-continent Mapping Center of the USGS on stable transparent mylar were used as base maps. Identical copies of these base maps were made at the same scale on stable transparent mylar by the Virginia Department of Highways using a diazo process.

Delineation of SAV bed boundaries onto the topographic quadrangle maps was facilitated by superimposing the photographic print with the appropriate mylar quadrangle on a light table. SAV boundaries were then traced directly onto the 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 percent cover within each bed was made visually in comparison with an enlarged Crown Density Scale similar to those developed for estimating of forest tree crown cover from aerial photography (Fig. 6). Bed density was classified into one of four categories based on a subjective comparison with the density scale. These were: 1, very sparse (<10% coverage); 2, sparse (10 to 40%); 3, moderate (40 to 70%); or 4, dense (70-100%). Either the enti-re bed or subsections within the bed were assigned a number (1 to 4) corresponding to the above density categories. Additionally, each distinct SAV unit (bed or bed subsection) was assigned an identifyring two letter designation unique to its map. Subsections of beds were further identified as being part of a contiguous bed by the addition of two letters unique to each contiguous bed. These contiguous bed descriptions aid the tracking of a single bed between quad sheets as well as the analysis of those beds that had to be separated due to variation in SAV density. SAV Perimeter Digitization and Area Calculation The perimeters of all SAV beds mapped from the aerial photography were digitized in a cloc'kwise direction using a Numonics Model 2400/2200 DigiTablet Graphics Analysis System having a resolution of .001 inches (.00254 cm) and an accuracy of .005 inches (.0 127 cm). Coordinates were transmitted to a PRIME 9955 computer for area calculations and data manipulation via software developed at VIMS. Each SAV bed was digitized at least four times and the area reported as a mean of three. 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 pe-rimeter was stored as X and Y coordinates in centimeters from the quadrangle origin (lower left corner). Any 'island' within a polygon (digitized SAV perimeter) was disregarded as long as a line was drawn from the outside of the polygon to the "island" and the resulting polygon was digitized in a clockwise direction. The line connecting the 'island" polygon to the larger surrounding polygon was drawn in by the digitizer operator. 10 5[f:. .1 n- 10-40 i?t. 15 25 j7 35;5T . .0* heel led 45 fFi 55 65 I 5 U o B 40-70 Si 75l f9 S 85 a a a70-100 95f lf : PERCENT CROWN COVER Figure 6. Crown density scale used for determining density of SAV beds: (1) Very sparse, 0-10%; (2) Sparse, 10-40%; (3) Moderate, 40-70%; (4) Dense, 70-100%. 11 SAV bed area in square centimeters on the chart was calculated via the following equation: A =l/2 I (XI* Y2 -X2* YI)+(X2* Y3 -Xa* Y2) +... +(Xn* Yi - Xi* Yn) I where Xn and Yn are the nth digitized perimeter points in centimeters. The area is then converted from square centimeters on the chart to square meters on the ground. This is done via the following conversion based on a chart scale of 1:24,000: A(2on ground) = A,(cm2 o ncat * 57600 Cm2 on ground I cm2 on chart) where Ag is the area on the ground of each SAV bed and Ae is the area on the chart. The area on the ground is then stored for later use. Tests of Precision and Accuracy Prior to each digitization session, the Numonics instrument was checked manually against a digitizing standard. After a map had been secured to the digitizing tablet, the standard was secured to the map and digitized four times. The information from digitizing the standard was transmitted to the beginning of the SAV bed Perimeter File on the PRIME 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 va-riation 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 standa-rd 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 then 0.10 cm another warning to check the system was printed. Any movement in absolute location can be indicative of digitizer instrument drift or chart movement during the digitization session. These cheecks assure that the final calculated bed locations are as accurate as possible. Maximum accuracy was maintained by exclusively using mylar topographic quadrangles rather than paper ones which can change scale as a function of changes in air temperature and humidity in the digitizer roorn. Calculation of SAV Red Mean Area and Choice of Representative SAV Bed Every SAV bed mean area was the result of at least four independent digitizations of the outline of each SAV bed. The computer made an area calculation of each replication and the three bed outlines or perimeters most similar in termns of area were then used for the calculation of a mean area. The perimeter defining the area most similar to the mean area was 12 then saved by the computer program as the representative perimeter for this specific SAV bed. Representative perimeters for all 1989 SAV beds were later converted to latitude and longitude and a copy of each on computer tape was then sent to the EPA Chesapeake Bay Program Computer Center for incorporation into the ARC INFO Geographical Information System. The areas used in the mean area calculation do not by contract requirements have a range in excess of 5% of the mean area. All bed areas having an error rate in excess of 5% are flagged by the VIMS quality assurance quality control computer program for additional error assesment. The VIMS error rate is normally less than 1%. 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 1989 SAV maps and the SAV bed perimeter cIomputer 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, and 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. Conversion of SAV Perimeter Points from XY Centimeters to Latitude and Longitude Before SAV perimeter information was to be exported to the EPA Chesapeake Bay Program Computer Center, the perimeter points had to be converted from X,Y centimeters to the more generally applicable latitude and longitude. This is done via a three step two dimensional linear interpolation between the four corner points of every quadrangle. At the start of digitization of every chart, the location of each corner point in X,Y cm and in latitude and longitude is recorded at the head of the data file. The corners are numbered: 1 = lower left corner or chart origin 2 = upper left corner 3 = upper right corner 4 =lower right corner These co-rner points are then used to convert each individual X'Y perimeter point to latitude and longitude. If additional files are needed for a given chart, a new set of corner points are digitized and stored at the head of these files. 13 The steps for the conve-rsion from X,Y cm to latitude and longitude are: 1.Transpose each XYY perimeter point from the original, non orthogonal (not at right angles) chart axes defined by the original four corner points to a new set of orthogonal chart axes and defined by a new set of four corner points. 2. Calculate centimeter to latitude and longitude linear conversion factors from the transposed chart corner points via: XCONV = 0.125 / (XCORNERPOINT(4) - XCORNERPOINTM)) YCONV = 0.125 / (YCORNERPOINT(2) - YCORNERPOINT(1)) Where: XCONV is the X cm to lat,lon conversion factor. YCONV is the Y cm to lat,lon conversion factor. 0.125 is a constant representing the distance in decimal degrees latitude or longitude between each successive chart corner point. XCORNERPOINT(# is the X value in centimeters of the numbered chart corner point. YCORNERPOINT(# is the Y value in centimeters of the numbered chart corner point. 3. Perform linear conversions from orthogonal X;Y cm perimeter point to latitude and longitude via the following equations: YLAT =YCHARTM1 + (YPORTH * YCONV) XLON =XCHARTM1 - (XPORTH * XCONV) Where: YLAT is the new Y point in decimal degrees latitude. XLON is the new X point in decimal degrees longitude. YCHALRT(# is the latitude of the chart corner point. XCHIART(#) is the longitude of the chart corner point. YPORTH is the Y perimeter point in cm from the orth- ogonal chart coordinate system. XPORTH is the X perimeter point in cm from the orth- ogonal chart coordinate system. These new latitude and longitude perimeter points are then stored in a special EPA submission file for VIMS SAV Data. The submission file structure is fully documented in Orth et al., 1988. 14 Organizational Provinces 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 area between the mouth of the bay to a line stretching from the mouth of the Potomac River at Smith Point in Virginia to approximately 3 nautical miles south of Tangier Island then extending to the eastern side of the bay to an area just south of the mouth of the Little Annemessex River is referred to as the Lower Bay zone. The area between the south shore of the Little Annemessex River and the south shore of the Potomac River to the Chesapeake Bay bridge at Kent Island is 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 (5-18'/oo), Middle zone; oligohaline (0.5-5 0/00), Upper zone. Although the major rivers and smaller tributaries of the bay have their own salinity regimes, the distribution of SAV in each river is discussed within the zone where it connects to the bay proper. In addition, 21 major sections of the bay are identified for more detailed discussion of SAV distribution (Fig. 7, Table 3). These sections, which were first delineated for the 1984 survey (Orth et al., 1985) and had been slightly modified for the 1987 survey (Orth et al., 1989), denote relatively distinct parts of the bay and its tributaries that are readily identifiable from a map. The section boundaries used for analysis and discussion of the 1989 SAV distribution and abundance data are those used for the 1987 report (Orth et al., 1989). Sections I through 4 are located in the Upper Bay zone. Sections 5 through 13 are located in the Middle Bay zone, and sections 14 through 21 are located in the Lower Bay zone. Appendix B gives the latitude and longitude of the boundary points of each Chesapeake Bay section and Chincoteague Bay in decimal degrees. SAV distribution in Chincoteague Bay is presented and discussed separately from the Chesapeake Bay. 15 3940. 0 3910.0o - \ i W ~o.o- 3840. - \ ' 16 , b16 w 111 0 3710, 0 -- 3640.0 I o 0 0 0 0 Figure 7.

""-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 major zones. These new boundaries have been retained for this report. (Refer to Figure 7 and Appendix B for boundary locations). 18 Ground Truth and Other Data lBases Ground truthing was accomplished by cooperative efforts of a number of agencies and individuals. Although incomplete for most areas, ground truthing confirmed the existence of some SAV beds mapped from 1989 aerial photography, located a few 1989 SAV beds not visible from the photography, and provided species data for many of these beds. Ground truth survey info-rmation supplied to VIMS researchers was included on the SAV distribution and abundance maps reproduced in Appendix C to show positions of the survey stations in relation to the 1989 beds of SAV mapped from the ae-rial photographs. Each survey was designated by a unique symbol to identifyr 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. Additionally, all ground truth data supplied to VIMS referenced on copies of 1987 SAV maps was tabulated in Appendix E and cross-referenced at VIMS by 1989 bed locations. For those areas in Virginia waters where aerial photographic evidence of SAV beds was inconclusive, photo-verification was accomplished by ground t-ruthing. Observations were principally made from small boats and by divers snorkeling over areas indicated from the photographs. In several river systems included in this survey (Yrk, Piankatank and Rappahannock) where VIMS -researchers transplanted SAV (principally eelgrass), transplant sites also were examined carefully by divers for any extant SAV. Citizen Field Observation data for Virginia waters (compiled by the USFWS) were also added to the 1989 Virginia SAV maps reproduced in Appendix C. In addition, a great deal of ground truth information could be extrapolated from earlier studies (Orth et al., 1979; Orth and Moore, 1982) since SAV beds in this region contain primarily one or two species and have not undergone drastic fluctuations in distribution and abundance since the first bay-wide survey in 1978. In Maryland, ground truth data were obtained in 1989 by the USGS Potomac River survey, two SAV research and transplanting projects, a USFWS survey, and the Citizen's and Charterboat Captain's volunteer surveys (both data sets compiled by the USFWS along with their own survey data). USFWS personnel surveyed selected locations in the upper bay by boat using rakes to collect samples to determilne presence or absence of SAV. Plants collected were identified to species when possible. SAV sightings were referenced on USGS 7.5 minute topographic maps. USFWS staff transferred data from these surveys to full-scale copies of 1987 SAV distribution maps (USGS 7.5 minute topographic quads with 1987 SAV beds). These USFWS-prepared survey maps were supplied to VIMS SAV researchers and survey data were transferred by VIMS staff to the 1989 SAV distribution maps reproduced in Appendix C. USFWS survey data was tabulated, locating each SAV siting by listing its associated 1987 bed. This table was supplied to VIMS where additional survey data were added and it became the basis for the corrected and 19 much expanded table published in Appendix E. In this latter VIMS version of the USFWS table, all ground truth data were added from the additional surveys, as noted in this report, and all were cross-referenced by 1989 bed locations. The field study in the Potomac River by the USGS, which covered the shoreline areas from the District of Columbia (D.C.) to the Route 301 bridge near Morgantown, Md., used shoreline surveys to document the distribution of SAV in the tidal freshwater and transition zones of the Potomac River. The USGS conducted shoreline surveys in the tidal freshwater portion of the river and tributaries, specifically the reach between Washington, D.C., and Indian Head (quads 40, 34, 28 and 48), from June to August, and in selected locations further south to Aquia Creek (quad 55) in October of 1989. The transition zone was surveyed in August for SAV by spot-checking in the Port Tobacco quad (16 1) and Nanjemoy quad (56). These surveys were done by boat, using rakes to collect samples to determine presence or absence of SAV. Plants were identified by species and the proportion of each was estimated for vegetated areas. Each vegetated area with species proportions was referenced on USGS 7.5 minute topographic maps by the surveyors. USGS survey maps were supplied to VIMS SAV researc'hers and survey data were transferred by VIMS staff to the 1989 SAV distribution maps (reproduced in Appendix C) and were tabulated in Appendix E. One 1989 SAV transplanting project being conducted on the Susquehanna Flats by Stan Kollar of Harford Community College provided data in the form of species presence by percentage, primarily by visual estimates. Species locations from these data were added to the 1989 SAV maps reproduced in Appendix C and were tabulated in Appendix E by VIMS staff. A SAV research group at University of Maryland Horn Point Environmental Laboratories (HPEL), headed by Court Stevenson, also provided 1989 ground truth data. Maps of their study sites on the Choptank River were provided to VIMS researchers and were annotated on the maps for this report (Appendix C) indicating the species reported for 1989. This ground truth data was also tabulated in Appendix E. In addition to the scientific surveys, private citizens participated in identifying 1989 SAV beds by checking certain areas in the bay for the previous years SAV bed locations for presence of SAV and by locating SAV bed locations new in 1989. Two groups were responsible for looking for SAV under the sponsorship of separate organizations. The Maryland Charterboat Association participated in the baywide effort, funded by the Maryland Department of Natural Resources (MD DNR) Watermen's Assistance Program. Boat captains were provided with reduced 1987 SAV quadrangle maps to aid in location of 1989 SAV beds and with data sheets on which to record informnation on each 1989 SAV bed identified. Sampling of SAV sites was undertaken at low tide. Samples were taken by hand, net or rake. Plants were identified as to species onsite or placed in zip-lock plastic bags and sent to the MD DNR for identification. 20 Private citizens volunteered to assist in the 1989 SAV ground survey under guidance of the USFWS and the Chesapeake Bay Foundation (CBF). This program entailed identifying and recording the location of SAV in the bay in 1989. Volunteers who were recruited through press releases, newsletters and personal letters were provided with a SAV identif'ication guide, reduced 1987 SAV maps to aid in location of SAV beds and data s'heets for visits to numerous sites around the bay. Each volunteer was asked to identify the location where SAV was sighted, and the species identified were counted. All information from the Charterboat Captain's survey and Citizen's survey was submitted to Linda Hurley and Kathy Reshetiloff (USFWS) for processing. SAV sitings reported by the Citizen's and Charterboat Captain's surveys were mapped on 1987 SAV maps. As previously explained, USFWS personnel also tabulated data from most of the 1989 Citizen's and Charterboat Captain's surveys along with their own survey's data, listing each SAV siting by 1987 bed location. VThMS staff mnapped these data on maps reproduced in Appendix C, and data were tabulated in Appendix E. 21 RESULTS Data Presentation SAV distribution data are presented by topographic quadrangle (Table 4), by section and zone (Table 5), and by quadrangles within a section (Table 6). Topographic 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 1989. 1989 SAV distribution data and species occurrences are furst 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 1987 survey (Orth et at., 1989) of SAV distribution and abundance. SAV is plotted for each section and for Chincoteague Bay in Figures 8 through 29. (SAV is plotted in red, a starred line represents a section boundary, latitude and longitude are in decimal degrees along the vertical and horizontal axes, respectively, and USGS 7.5 minute topographic quadrangles are represented by a grid of numbered rectangles. Refer to Table 2 for quadrangle names listed by map number.) 1989 SUMMARY In 1989, the Chesapeake Bay had 24,134 hectares of SAV, compared to 20,119 hectares in 1987, with 2,458 (10%), 11,507 (48%) and 10,169 (42%) hectares occurring in the Upper, Middle and Lower Bay zones, respectively (Figs. 1 and 2). Upper Bay Zone Seventy-nine percent of the SAV within the Upper Bay zone was located in the Susquehanna Flats section (1,945 hectares). Nine species of SAV were documented by ground truth surveys in this section, with M. spicatum being the dominant species. Hydrilla verticillata was found in the Flats but occurred in small isolated beds. In addition to the reduced overall abundance of SAV from 1987 (2,219 hectares), beds were generally much less dense, with 95% of all SAV beds classified as very sparse (0-10% coverage), and no beds classified as dense (70-100% coverage). There were 308 hectares SAV in the Upper Eastern Shore section located principally in the Elk and lower Sassafras Rivers, Swan, Stillpond and Chum Creeks, with many of the same species as reported in the Susquehanna Flats section. In the Upper Western Shore section (38 hectares) SAV was concentrated in Saltpeter and Seneca Creeks, with M. spicatum and V. americana being most abundant. In the Chester River section (167 hectares) SAV was most abundant adjacent to Eastern Neck and Eastern Neck Island and in the lower Chester River. In this region R. maritima was the most abundant of six species which were reported. Middle Bay Zone Forty-five percent of the SAV in the Middle Bay Zone (5,196 hectares) was found in the Mid-bay Island Complex where R. maritima and Z. marina were present, in 22 Table 4 Total Area Of SAV In Hectares By USGS 7.5 Minute Topographic Quadrangles For 1987 And 1989.

Eighteen percent (1,998 hectares) of the SAV in this zone was present in the Middle Eastern Shore section, 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 being the dominant species reported for this area Little or no SAV was mapped or reported from the Central Western Shore, Middle Western Shore, and Patuxent River sections. The Middle Bay zone also includes the entire Potomac River, where 2,614 hectares of SAV were present in 1989. SAV was concentrated in two distinct zones: 1. the tidal freshwater region (the Upper Potomac River section with 1,998 hectares) where H. verticillata remained the numerically dominant species (eight other species were recorded from the USGS and Citizen's surveys); and 2. the region around the Route 301 bridge (the upper portion of the Lower Potomac River section with 616 hectares), including Nanjemoy Creek and Port Tobacco River, with V. americana and M. spicaum being the most frequently reported species in this area. Although the total abundance of SAV in the upper section increased from 1987 (1,665 hectares), many of the very dense beds from the Woodrow Wilson bridge to just below Piscataway Creek declined. The'decline was offset by the large increases in SAV from Qumntico Creek to Aquia Creek, along both shores. Lower Bay Zone SAV was abundant throughout the entire Lower Bay zone except for the James River. Forty-five percent of SAV in the Lower Bay zone was found in the Lower Eastern Shore section, around the Fox Islands and the mouths of major creeks (i.e. Cherrystone Inlet, Hungars Creek, Mattawoman Creek, Occahannock Creek, Craddock Creek, Pungoteague Creek and Onancock Creek). Along the western shore, SAV was abundant in Mobjack Bay (15% of SAV in the Lower Bay z6ne), lower York River, Back River and Drum Island Flats area adjacent to Plum Tree Island. Both R. maridtma and Z. marina were abundant throughout this zone. Ruppia marit/ma continued to increase in abundance in both the Piankatank and Rappahannock Rivers. Zostera marina is present in several sections resulting from previously successful transplant efforts. Chincoteague Bay SAV in Chincoteague Bay was little changed in distribution from 1987, with 2,310 hectares reported in 1989. All of the SAV consisted of R. marit/ma and Z. marina, and was located along the eastem side of the bay behind Assateague Island. 39 1. SUSQUEHANNA FLATS There were 1,945 hectares of SAV in the Susquehanna Flats section in 1989 (Tables 4-6; Fig. 8; Appendix C, Maps 2, 3 and 9) compared to 2,219 hectares mapped in 1987. In addition to the reduced overall abundance of SAV from 1987, beds were generally much less dense as compared to 1987 densities (95% of the beds are classified as very sparse, and no beds were classified as dense). SAV beds were located principally in two main areas: 1. very sparse to moderate fringing beds in the Susquehanna River consisting primarily of M. spicatum, with P. pectinatus, C. demersum, V. americana, H. dubia and N. guadalupensis in lesser amounts from Spencer Island to the river mouth at Havre de Grace on the west side, and to Stump Point at the mouth of Mill Creek on the north side; and 2. a large area of very sparse SAV located in the broad shoal area at the river mouth. This broad shoal consisted primarily of small patches of M. spicatum, with P. pectinatus, V. americana, C. demersum and N. guadalupensis. A total of nine species (M. spicatun, H. dubia, V. americana, H. verticillata, C. demersum, P. pectinatus, N. guadalupensis, P. perfoliatus, and Najas spp.) have been reported either by Stan Kollar of Harford Community College, the Citizen's or the Charterboat Captain's surveys. SAV beds consisted of up to five species, with M. spicatum being dominant Heteranthera dubia, V. americana, H. verticillata and C. demersum also occurred in significant amounts. SAV remains virtually absent from Mill Creek, Furnace Bay, Northwest River, Swan Creek, Spesutie Island and western Elk Neck. 2. UPPER EASTERN SHORE There were 308 hectares of SAV mapped for the Upper Eastern Shore section in 1989 (Tables 4-6; Fig. 9; Appendix C, Maps 4,5,9, 10, 15, 16, 17 and 21), compared to 103 hectares mapped for 1987, consisting of very sparse to sparse beds (35% and 63%, respectively, of the total coverage within section 2). Principal locations of beds were in the Elk River, Swan Creek, lower Sassafras River, Stillpond Creek and the mouth of Chum Creek. Very little SAV was mapped in the Bohemia River and along the mainstem of the bay from Stillpond Creek to Swan Point This section has contained relatively little SAV since the baywide SAV survey program began in 1978 although, historically this section has contained abundant SAV (Stevenson and Confer, 1978). Myriophyllum spicatum and V. americana were the two most commonly reported species, with seven other species (H. verticillata, C. demersum, P. pectinatus, E. canadensis, Z. palustris, P. crispus and R. maritira) reported in lesser amounts as determined by the Citizen's and Charterboat Captain's surveys. 3. UPPER WESTERN SHORE There were 38 hectares of SAV mapped from the aerial photographs in 1989 for the Upper Western Shore section (Tables 4-6; Fig. 10; Appendix C, Maps 13 and 14) compared to 117 hectares in 1987. SAV beds were concentrated in Saltpeter and Seneca Creeks. Very little or no SAV was reported in the Back, Patapsco, Bush, Gunpowder, Middle and Magothy Rivers. 40 3937. 5 , , I , .... , , ...... 1002 . 003 . 004 - HAVRE DE GRACE UEHA FLAT' 3930.0. o008 sWAN CREEKAL\ _- < %ESUTIE ri SLAND p 009 ( :1 0. 3922. 5 " ITii , I I I I I I I I I I I I , I I I I I ,,, I,rl I,,,I II O in O lt (Di u (i u) Figure 8.

CHESTER RIVER There were 167 hectares of SAV in the Chester River section in 1989 (Tables 4-6; Fig. 11; Appendix C, Maps 20, 21, 26 and 33) compared to 515 hectares in 1987. Most of the SAV was located adjacent to Eastern Neck and Eastern Neck Island, and in the Chester River. Additional beds are found in Rock Hall Harbor, The Haven, Swan and Huntingfield Creeks, located above Eastern Neck on the Chesapeake Bay. Six species of SAV were reported from this section in 1989 by the Citizen's, Charterboat Captain's and USFWS surveys (maps 21 and 26). Ruppia maritima and P. perfoliatus were by far the most commonly reported species in this section with P. pectinatus, M. spicatum, E. canadensis and Z. palustris being reported less frequently. 5. CENTRAL WESTERN SHORE There was no SAV observed from the aerial photography in the Central Western Shore section in 1989 (Tables 4-6; Fig. 12) which was similar to 1987. Although not evident in the aerial photography, the Citizen's survey reported SAV, primarily P. pectinatus, Z. palustris and R. maritima, from a few sites in this section (maps 23, 30,35). 6. EASTERN BAY There were 831 hectares of SAV identified from the Eastern Bay section in 1989 (Tables 4-6; Fig. 13; Appendix C, Maps 32, 33, 36 and 37) compared to 900 hectares reported in 1987. SAV occurred as very sparse to sparse beds throughout this section (14% and 72% of the total SAV coverage within section 6, respectively). In 1989 SAV was identified as being particularly abundant along both shorelines in Crab Alley Bay, Prospect Bay, Parson Island, PLney Neck and the lower portion of the Miles River. Little SAV was present from Punch Point on the Western shore of Eastern Bay to Pawpaw Cove on Tilghman Island, as well as in the Miles and Wye River. Ruppia maritima, P. pectinatus and Z. palustris were reported by the Citizen's survey (maps 32, 33 and 37). However, field information from this source as well as the Charterboat Captain's survey was very limited compared to previous years. 7. CHOPTANK RIVER There were 865 hectares of SAV observed in the Choptank River section in 1989 (Tables 4-6; Fig. 14; Appendix C, Maps 43, 44, 51, 52 and 62) compared to 356 hectares in 1987. Most of the SAV occurred in sparse to moderate beds in only a few areas (24% and 64% of the total coverage within section 7, respectively). Most of the SAV was found in Harris Creek and Brannock Bay. Other areas were principally along the eastern side of Tilghman Island, the mouth of Chapel Creek, Cook Point Cove, Covey Creek and Cators Cove. There was little or no SAV in Broad Creek, 44 3915. 0 '' _020 I021 022 .0 2 5 _AYS _-025 CR4Ys INN 027-_ - Z/ 0, o_o%; , . 033 ' 3 852. 5 ' I.' 0 tn 0 tCDtD(D CD Figure 11.

Vegetation above Chapel Creek in the Choptank River is sparse but not completely absent. Ground surveys by Citizens and Charterboat Captains, as well as scientists from the University of Maryland's Horn Point Environmental Laboratories, located three species of SAV in this section (maps 36,43, 44, 51, 52, 62) with R. maritima being the most prevalent. Potamogeton pectinatus and Z. palustris were observed in scattered locations. 8. PATUXENT RIVER There were 3 hectares of SAV reported in the Patuxent River section in 1989 (Tables 4-6; Fig. 15) compared to 41 hectares reported in 1987. SAV in the Patuxent River has always been at very low levels of abundance and has not exceeded 50 hectares in any year since the baywide effort began in 1978. There were sporadic sightings of four SAV species in the Patuxent River by the Citizen's and Charterboat Captain's surveys (maps 49,60,61,70,71, 159). Those species reported from the lower sections of the river were: Z. palustris, P. pectinatus, M. spicatum and R. mariti/a., Species found from the upper sections of the river were V. americana, C. demersum, P. pectinatus, N. guadalupensis, E. canadensis, P. crispus, P. pusillus and Najas spp. 9. MIDDLE WESTERN SHORE There were no SAV beds identified in the Middle Western Shore section in 1989 (Tables 4-6; Fig. 16) which was similar to 1987. There were no observations from ground surveys in 1989. Most of the littoral area in this broad section of the bay is composed of exposed beaches of high energy that are unsuitable for SAV growth. Therefore, we would not expect large expanses of SAV, rather only small pockets of SAV in creeks or ponds that empty into the bay. Previous surveys have reported no more than 23 hectares of SAy. 10. LOWER POTOMAC RIVER There were 616 hectares of SAV identified in the Lower Potomac River section from the 1989 aerial photography (Tables 4-6; Fig. 17; Appendix C, Maps 56, 57, 65, 66,67 and 161) compared to 458 hectares reported in 1987. All of the SAV, except for a small bed near the mouth of the SL Mary's River, occurred in the region near the Route 301 bridge, in Nanjemoy Creek and Port Tobacco River, and in the shoreline adjacent to these two creeks. A majority of SAV beds were densely vegetated with 71% of the total SAV within section 10 in density class 4. SAV beds were fringing along the eastern side of Mathias Point Neck to the Route 301 bridge. Several small beds were observed in Machodoc, Rosier and Cuckhold Creeks, just below the Route 301 bridge. Citizen's survey observations were made only in the SL Mary's River (map 80) where R. maritima was the only species present, Herring Creek (Piney Point, map 79) where R. maridma and Z. marina were reported, and in Breton Bay (Leonardtown Quad, map 69) where E. canadensis and P. perfoliatus were observed. USFWS and USGS surveys were made in the Port Tobacco River and Nanjemoy Creek (maps 56 49 3837. 5 3830. 0, 7 'V 060 061 059 3822. 5 , 069 070 - A t071 3815. . in N o N �d- rcl i riN (o (D (D, ( Figure 15.

They reported V. americana, M. spicatum, P. perfoliatus, C. demersum, P. pecinatus, Najas spp., P. pusillus, P. crispus and R. maritima. The USGS also reported P. perfoliatus near the Route 301 bridge on the Virginia side of the Potomac River. 11. UPPER POTOMAC RIVER There were 1,998 hectares of SAV mapped in the Upper Potomac River section (Tables 4-6; Fig. 18; Appendix C, Maps 34,39,40,47,48,55,65 and 161) compared to 1,655 hectares reported in 1987. A total of 69% of the SAV beds were densely vegetated (density class 4). Although the total coverage of SAV in this section had increased, many of the dense beds from the Woodrow Wilson Bridge (except the one in the middle of the river) to just below Piscataway Creek were no longer present or reduced in coverage. SAV distribution in the Alexandria and Mount Vernon Quadrangles declined 21% and 68% from 1987, respectively. SAV increased from Quantico to Aquia Creek, along both shores, with large increases in the Indian Head (17.6 to 184.0 hectares), Widewater (39.2 to 466.6 hectares), King George (3.6 to 37.4 hectares) and Fort Belvoir (19.3 to 63.5 hectares) quadrangles. SAV is still absent from Occoquan Bay, Belmont Bay and Aquia Creek. Numerous SAV species were reported by the Citizen's survey (maps 39,40 and 48) which included H. verticillata, M. spicatum, C. demersum, H. dubia, N. minor, V. americana, P. pectinatus and P. pusillus. Results from the USGS survey of this region (maps 34,39,40,48 and 55), which was less quantitative than in previous years, were very similar to that reported from the Citizen's survey but also included N. guadaiupensis. 12. MIDDLE EASTERN SHORE There were 1,998 hectares of SAV identified in the Middle Eastern Shore section (Tables 4-6; Fig. 19; Appendix C, Maps 63, 72,73, 74, 82, 83, 84, 85,92,93,100 and 101) compared to 1,527 hectares reported in 1987. SAV beds, of which 65% were dense (class 4), 17% moderate (class 3), and 17% sparse (class 2), were very abundant in: 1. the lower Honga River adjacent to Middle Hooper Island, Wroten Island, Parks Neck and Asquith Island; 2. between Barren Island and Meekins Neck-Upper Hooper Island; and 3. the lower Manokin and the Big and Little Annemessex Rivers. Few SAV beds were observed in Fishing Bay and in the Nanticoke and Wicomico Rivers. Ruppia maritima was the predominant species found by the Citizen's and Charterboat Captain's surveys (maps 72, 73,74,75, 82,83,84,85,91, 92, 100 and 101). Zostera marina was reported from several locations on the Great Fox Island (map 100) and Crisfield (map 101) quadrangles. 13. MID-BAY ISLAND COMPLEX There were 5,196 hectares of SAV mapped in the Mid-Bay Island Complex in 1989 (Tables 4-6; Fig. 20; Appendix C, Maps 83,91,92,99, 100 and 107) compared to 4,265 hectares reported in 1987. This section contains 21.2% of the SAV in the entire Chesapeake Bay. The broad, expansive shoal area between Tangier Island and Smith Island continued to be densely vegetated by both R. maritinma and Z. marina, 53 3852. 3845.C0' 039 040 3837. 5 047 1 A TAWOMAN 1UA C CIBEEK CREE C~~~~ 0~048 3830. 0 055 056 057 AQJIA :R.

Eighty percent of the SAV within this section was in density class 4. Ruppia maritima was the species most often reported by the Charterboat Captain's survey around these islands, with one report of Z. marina. Previous VIMS surveys had documented much more extensive occurrences of Z. marina. 14. LOWER EASTERN SHORE There were 4,718 hectares of SAV observed in the Lower Eastern Shore section in 1989 (Tables 4-6; Fig. 21; Appendix C, Maps 100, 101, 107, 108, 109, 113, 114,119, 124, 133, 134, 142 and 143) compared to 4,036 hectares reported in 1987. Large, dense beds (50% of the total SAY is in density class 4) of Z. marina and R. maritima (includes observations from both the Citizen's and Charterboat Captain's surveys; maps 100, 101 and 133) continue to persist at the mouth of Cherrystone Inlet near Cape Charles, at the mouths of Hungars Creek, Mattawoman Creek, Occohannock Creek, Craddock Creek, Pungoteague Creek, Onancock Creek and Chesconessex Creek, 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 Islands. Those areas between the above mentioned creeks were sparsely vegetated. This was due largely to the dynamic and exposed nature of these sites. There was very little SAV in the Pocomoke Sound area, and there was no SAV south of Old Plantation Creek just below Cape Charles. 15. REEDVILLE REGION There were 492 hectares of SAV identified in the Reedville Region in 1989 (Tables 4-6; Fig. 22; Appendix C, Maps 106 and 112) compared to 324 hectares reported in 1987. SAV beds consisted of sparse, moderate and dense beds (19%, 47% and 21% of the total SAV within this section in density classes 2, 3 and 4, respectively) of R. maritima and Z. marina. (Species identification was based on prior years scientific and Citizen's information since there was no ground truthing here for 1989.) Most beds were found in Little Bay, Dymer Creek, Indian Creek, Ball Creek, Dameron Marsh, Fleeton Point and Taskmasker Creek. 16. RAPPAHANNOCK RIVER COMPLEX There were 669 hectares of SAV observed in the Rappahannock River Complex in 1989 (Tables 4-6; Fig. 23; Appendix C, Maps 110, 111,116, 117,118 and 123) compared to 208 hectares reported in 1987. SAV beds consisted mostly of sparse to moderate beds (77% in density classes 2 and 3). SAV has continued to rapidly increase in this system since 1986 when only 18 hectares were mapped. Ruppia maritima continues to be the dominant species in both the Rappahannock and Piankatank Rivers. In particular, dense beds of R. martima were again present in the Corrotoman River (includes obervations from the Citizen's and VIMS surveys). Ruppia maritima is now present in small scattered patches along the north shore of the Rappahannock River above Towles Point. Zostera mnarina, once a dominant species in this section similar to the other sections in the lower bay but rare since 1971, is now present in small patches in both rivers. This is a result of successful transplant efforts 57 3 800 - 0_L1111 3~ ~100.1 011111 ;uHm1 11 Y I Ili I 4IIIIli I I II IIIIJJ I 1.1 GREAT ' "F~~FC 3752. 5 POY 107 3745.0 - I' I 14 1fiEE 42 3 ~~~CRC 3737. 5 3730. 0 1722. 5 b; 133 134~I 371 5. 0 AL I14 3 70 7. 5 :14 3700. 0 j""" .\ "" Ln (D LO CD Ln CD C. o o to , m CN c) c) , I )n CN C.

In the Rappahannock River transplanted Z. marina is present adjacent to Parrott Island, off Sanders Cove just above the bridge, at the mouth of Carters Creek, Ball Point, off Wharton Grove and adjacent to Towles Point. In the Piankatank River and Milford Haven area transplanted Z. marina is present off Burton Point, along the northeast side of Gwynn Island and at the mouth of Healy and Hills Creek. Naturally occurring Z. marina is present on the west side of Gwynn Island off The Hole in the Wall and off the northeast tip of the island, and in the Willis Wharf area. 17. NEW POINT COMFORT REGION There were 346 hectares of SAV identified in the New Point Comfort Region in 1989 (Tables 4-6; Fig. 24; Appendix C, Map 132) compared to 238 hectares reported in 1987. SAV consisted of dense beds (68% is in density class 4) of Z. marina and R. maritima (observations include those from the Citizen's and VIMS surveys) between New Point Comfort and just north of Horn Harbor. 18. MOBJACK BAY COMPLEX The Mobjack Bay Complex contained 1,593 hectares of SAV in 1989 (Tables 4-6; Fig. 25; Appendix C, Maps 122, 123, 131 and 132) compared to 1,227 hectares reported in 1987. SAV beds consisting of Z. marina and R. maritima (observations include those from the Citizen's and VIMS surveys) were most abundant along the entire shoreline of Mobjack Bay as well as in three of four tributary rivers: Severn, Ware and North. Several small beds of R. maritima were observed within the East River. The Mobjack Bay area continued to harbor some of the more extensive SAV beds on the western shore of the lower Chesapeake Bay. Sixty-four percent of the total coverage of SAV in this section is in density class 4. 19. YORK RIVER There were 677 hectares of SAV observed in the York River section in 1989 (Tables 4-6; Fig. 26; Appendix C, Maps 130, 131, 132, 139 and 140) compared to 608 hectares reported in 1987. Dense SAV beds (80% of the total coverage in this section is in density class 4) consisting of both Z. marina and R. maritima (observations include those from the Citizen's and VIMS surveys) were located principally along the north shore from Gloucester Point to the mouth of the river. The only beds present along the south shore were located on the north side of Goodwin Islands. SAV beds were absent upstream of Gloucester Point on the north shore except for a small area of Z. marina (less than 0.5 hectares) adjacent to Big Mumfort Island. This area was planted from seeds broadcast in the fall, 1988 (VIMS, unpublished data). Small patches of Z. marina (approximately 1 - 2m2) are present just below the Naval Weapons Station on the south shore. These were transplanted in the fall of 1985, 1986, 1987 and 1988 (VIMS, unpublished data) and have persisted through 1989. Ruppia maritima is also present in this transplant area, but unlike Z. marina, has re-established naturally. The SAV beds planted at Gloucester Point in 1982 and 1983, as well as the smaller areas planted immediately adjacent to these larger areas from 61 3730. 0 I I I I I I I I I I I I I I I I I I I I I I 1 _ 123 3722.5 _ - -1f2, RN HARBOR MOBJACK 37_e1 3715.

LOWER WESTERN SHORE There were 1,670 hectares of SAV mapped in the lower Western Shore section in 1989 (Tables 4-6; Fig. 27; Appendix C, Maps 140, 141, 147 and 152) compared to 1,322 hectares reported in 1987. SAV consisting of Z. marina and R. mar/tnma (Citizen's and VIMS surveys) remained as dense beds. Sixty percent of the total coverage in this section is in density class 4 in Broad Bay, Back River, the mouth of Poquoson River off Pasture and Hunts Neck, Drum Island 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. 21. JAMES RIVER There were 4 hectares of SAV in the mainstem James River in 1989 (Tables 4-6; Fig. 28; Appendix C, Map 147). This small, 3.8 hectare (9 acre) dense bed located at the mouth of Hampton Creek adjacent to the Veteran's Hospital consisted predominantly of Z. marina. A small section of the Chickahominy that was identified as having SAV in 1989 was photographed. It included Cordon and Nettles Creek, and Nayses Bay. The photography showed SAV beds occurring in locations similar to previous aerial surveys indicating that these beds are relatively stable. However, SAV beds were not mapped because the observed beds occurred in small creeks and could only have been represented by a thin line on a 1:24,000 scale topographic quadrangle. Tracing and digitizing a single line rather than a polygon-shaped bed would have resulted in large errors, thereby compromising our quality control standards. Citizen's survey information from the Brandon quadrangle indicated fringing SAV beds consisting of N. quadalupensis, C. demersum and Chara sp. along Parsons Creek in Sunken Marsh by the Chickahominy main stem. SAV species are probably distributed throughout the Chickahominy River system occupying the fringes of many tidal creeks. CHINCOTEAGUE BAY There were 2,310 hectares of SAV identified in Chincoteague Bay in 1989 (Tables 4-6; Fig. 29; Appendix C, Maps 167, 168, 170, 172, 173 and 175) compared to 2,310 hectares reported in 1987. Seventy-four percent of the beds were moderate coverage and 21% were dense coverage. The Citizen's and Charter Boat Captain's surveys found both Z. marina and R. maritima throughout the bay (maps 167, 168, 170, 172 and 173). All of the SAV continues to be present on the eastern side of the bay adjacent to Assateague Island in water depths of less than 1 meter (MLW). The vegetation was concentrated in four relatively distinct areas identical to that reported in the 1986 and 1987 surveys. They were located west of the northern end of Chincoteague Island, and west of West Bay, Green Run Bay and the Tingles Island area. Seven percent of the total bottom of this region (32,536 hectares) supports SAV. 65 3715. II 111111 140 T 141 142 --GOODW~IN ISL. EOQu so , DRUM ISLAND FLATS 3707.
