probably do not correspond t-o the lower limits of s a l i n i t y t o l e rance i n

e e l g r a s s growth may be due t o n u t r i e n t loading.

For example, e e l g r a s s beds i n t-he nor th end of the West Branch

Dartmouth: Allens Pond t o Round H i l l (F igs . 5 + 6 )

This map were based on 1975 and 1981 a e r i a l surveys and seve ra l

f i e l d v i s i t s i n 1984 and 1985. Allens pond was not. included i n t h i s

This a rea has d ive r se h a b i t a t s i n which e e l g r a s s grows. Ee lgrass

i s abundant on the mud and sand bottom between the mout-h of t he Slocums

and L i t t l e Rivers around Potomska P t . The water i s d i s c e r n i b l y brown

and t u r b i d here during out-going t i d e s do t o t he d ischarge of t he Slocums

t h i s a r ea a r e heavi ly ep iphyt ized , perhaps due t o the n u t r i e n t content

of the r i v e r water. Because of t he water t u r b i d i t y and epiphyte growth,

e e l g r a s s grows only t o 0.9 m MLW i n a 4-6 m s t - r i p on e i t h e r s i d e of a

d i s t r i b u t i o n the re a s wel l . New seed l ings were observed i n t h i s a r ea

during the summer of 1984, but they were heavi ly epiphyt ized and no

perennial beds were found. Eelgrass also disappears abruptly at the 50

m south of the bridge at. Little River, but this is probably due the

shallowness of t-he flood delta there. It was not det.ermined whether

eelgrass g r o w north of the Lit-tle River bridge.

In contrast., the bed by Rarneys Joy (DARJ1) grows in a high

energy, well flushed, coarse sand environment, to 1.2 m MLW. This bed

was more robust. and had greater biomass (shoot density ) 409 rn-2, 190 g

dry wt rn-2 ; n=4, SE=10) . South of the channel at Pot-omska Pt. is a large sand flat.

Eelgrass may grow at t-he south-most deep edge of this feat-ure; but no

beds could be .identified from either t.he photographs or field visits.

Eelgrass beds visible on phot-ographs of the north side of Deep Point. the

during early 1970's disappeared because of erosion in that area in 1978.

Offshore from Allens Pond and Rarneys Joy, wave action is strong

and submerged vegetation could not be discerned on photographs. The

bott-om is covered with large boulders, but it. is likely some eelgrass

g r o w there, although its extant is unknown.

Mishaum Pt. has a large boulder field to its west, and eelgrass is

extensive here beginning at 0.6 rn MLW among the rocks. Eelgrass may

also grow along the southeastern and southwestern shores of Mishaum Pt.;

but this area was not field investigated and the sharp slope of the

bottom makes interpretation of the photographs difficult.

The beds indicated in Salters Pt. Pond may be algae. Whether they

are algae or eelgrass, the vegetation is less abundant in the 1981

photograph than the 1970's photographs. Outside of Salters Point Pond

is a dense eelgrass bed in which a transect was run. Biomass was 160 g

Apponagansett Bay, Dartmouth to Wen Bedford (Figs. 7 + 8 )

The map of eelgrass distribution in this area were based on 1975,

and 1981 photographs, and field visits in 1884 and 1985. This area has

had sizeable anthropogenic disturbances in the past, and bot-h

Apponagansett Bay and the New Eedford area have seen considerable

decline of eelgrass during the last 15-25 y (Chapter 4).

In field visit-s in 1985, eelgrass extended midway between Nonquit

and the Padanaram bridge on t-he Western shore. Similarly, eelgrass

disappears in the outer harbor near Giffords Warina on the eastern

shore. In 1985, no eelgrass was found north of the Padanaram bridge

despite reports that it does grow there. In phot-ographs t-aken prior to

1982, some eelgrass is present in the bay, but. many of these beds

apparently disappeared. Identification of phot-ographs is difficult in

some areas because of drift material, including the extreme north end of

the Bay along the banks of the bay. This area was not field verified

and it was assumed that this is drift algae or Rap,oia.

The absence of eelgrass in t.he inner harbor appears to be due t.o

increased light availability. For example, eelgrass grows south of the

Marina in the outer bay and continues southward to Ricketsons Pt at the

mouth of the harbor. Near the mo11t.h of the Bay, eelgrass grows down to

2.5 m MLW, however, the maximum depth of gr0wt.h decreases as one

proceeds northward and rises to 1.2 m south of the marina, then

disappears entirely. Epiphytic algae on eelgrass leaves increase

conspicuously along this same t-ransect.. Prominent accumulations of

Gracillaria and lJlva in the inner harbor further suggest that nutrient

This v e g e t a t i o n map was base on 1972, 1974, 1980, 1981 a e r i a l

s u r v e y s . Underwat-er and boa t o b s e r v a t i o n s were conducted i n 1984 and

1985 east of the mouth of New Bedford Inner Harbor, and south along the

western shore of Sconticut. Neck, at North Cove on West Island, and

around Nasket.ucket Pay.

Eelgrass is absent between the marshy embayment near Popes Beach

and Silvershell Beach, which has a conspicuous rock and algae field

offshore. No eelgrass was observed between this area and the shallows

north of Little Egg Island. Vegetation t-hat is apparent on photographs

is composed of drift and attached algae, particularly Cndium. These

shallows were not fully searched and they deserve further exploration.

On the southwestern Sconticut Neck shoreline, eelgrass is

extensive and dense, and relatively free of algal epiphytes. Large

rocks and cobbles are interspersed throiighout the area, but where t.here

is sand on the bot.tom, eelgrass grows to 3.0 m MLW. Northeast of Wilbur

Pt. and on the southern shore of West Island, eelgrass beds continue

along shore. Rock and algae cover sizable parts of the bottom in these

areas, especially nearshore. The lower limits of some of t.hese beds

could not be discerned from the photographs and are in part based on

bathymetric contours.

Eelgrass is extensive throughout Nasketucket Bay above 3.0 m.

Substrate between 3.0 and 3.5 m also has eelgrass, hut beds often

consist. of extensive bare areas. Biomass samples were collected with

SCUBA in North Cove on West Island, where eelgrass grows to 3.6 a MLW.

At the center of bed distribution, mean abovegrnund biomass equals 210 g

dry wt m-2.

No eelgrass grows on the rock and mud bottom of Little Pay, but.

algae (especially Cnditrm! are abundant there. The wat-er is turbid and

there is considerable growth of periphyton and drift. algae.

Eelgrass grows near Pea Island, and is extensive around Erant

Island, and patches of eelgrass continue on eit-her side of the sand bar

connecting Erant and Ram Islands. This is a high energy environment.

with a sandy bottom; the eelgrass coverage consisted of circular patches

2-10 m in diameter spread about 1 bed diameter apart in shallow areas.

South of Ram Island the margin of the eelgrass was difficult. to discern

on available photographs and is partly based on bathymetry.

Erant Island Cove was not. entered but. appeared to contain some

eelgrass in the 1981 photograph. Eelgrass may also grow around White

Rock, but this area was not investigated. Small patches of vegetation

bet-ween 2.4 and 3.6 rn MLW in Nasket.ucket Pay may be unrecorded.

Hattapoisett Harbor and vicinity (Figs. 11 + 12)

This eelgrass map was based on 1978 and 1981 photographs, and

except. for the Erant Island-Ram Island local described in Map 4, no part

of this area was examined in the field, although information was

obtained from the Mattapoiset.t shellfish warden.

Mattapoiset-t Harbor is moderately developed alongshore and is

subject. t.o considerable boat traffic. IJntil recently; a sewage outfall

had discharged in the harbor for many years. The slope of the shoreline

is st-eep, and much of the bottom is below the limits of eelgrass growth.

Eelgrass beds are easy t.o discern in most of this area from aerial

photographs, except the inner portion of Mattapoisett Harbor. Here,

poor water clarit-y, steep beach slope, and poor contrast between

vegetation and substrate combine t.o make photograph interpretation

difficult., and part.s of the lower bed boundaries are estimated based on

ba t.hyme try.

Eelgrass beds north and east of St-rawberry Pt. are distinct, hut

this is a high energy environment., and these beds show variability in

shape on recent. photographs, especially near shore. The vegetation

indicated in Pine Island Pond may be composed mostly of algae and or

Ruppia, and this area needs to be furt.her study. Rocky ledges offshore

and the mouth of the Mattapoisset River may also cant-ain eelgrass

populations.

Hiller Cove, Wattapoisett to Harion (Figs. 13 + 14)

Like the last area described, this vegetation map was based

primarily on aerial photographs (1972, 1974, 1978 and 1981) and

information from the shellfish warden. Only Rird Island and Rutler Pt.

were examined in the field.

Bird Island is surrounded by rock and boulder particularly on its

south side and is a moderately high energy environment. Nonetheless

eelgrass grows abundantly below t.he tidal wave act.ion and is quite dense

between the Island and Butler Pt., except. on the sand bar connecting the

two.

Blankenship and Planting Island Coves contain much algae and some

R!rppia. Eelgrass is present- here, but with low cover, and beds have

been declining in recent. years (G. Taft., pers. communication and chapter

4). In addition, drift algae have been accumulating here in recent.

Great Neck Wareham t o Pocasset , Bourne (Figs. 17 + 18)

The map of e e l g r a s s beds bet.ween Great Neck and Pocasset were

based on a e r i a l photographs, taken i n 1971, 1975, 1974, and 1981 and

f i e l d surveys i n 1985 and 1985 around Buttermilk Bay and a reas south t o

t h e Canal.

This region is dominated by shal low, pro tec ted embayment-s, with

good water c i r c u l a t i o n , i n p a r t due t o wat.er exchange through the Cape

Cod Canal. Most of the shallow coves have ext-ensive eelgrass cover

making this region and the adjacent sout-h shore of Great. Neck have the

highest tot-a1 coverage of any area in this study.

Batt.ermilk and Li tt.le But terailk Bays are typical of the shallow

embayments in this area, and eelgrass grows densely in each !(1.5 m MLW

and (1.2 m MLW respectively). Dense beds also occur in Onset Bay and

around Great Neck and Point Independence. The vegetation indicated in

the upper reaches of some of these coves, for example, bed BOTIS at

Toby's Island, bed BOAP2 at Mashnee Island, as well as the beds

northwest- of Shell Pt., and in Broad Cove probably contain considerable

amounts of drift algae and possibly R u p p i a .

Among the int.erest.ing feat.ur-es in this region are the eelgrass

beds surviving on the Canal f land deltas south of Taylor Pt. and

Mashnee Island. These beds occupy a region of high current velocity and

have a very distinct. striated pattern.

Between Little Bird Island (Map 7A) and Stony Point, a shallow

shelf covers hundreds of hect-ares with a dept.h of 1.8 to 3.0 m; much of

. it covered with eelgrass, forming some of the largest eelgrass beds in

Buzzards Bay. Water transparency is bet.t.er here than at Longbeach

because water clarity improves wit.h increasing distance from the Wareham

River toward the canal, and eelgrass grows to at least 3.0 m. Like the

Longbeach Point shoal, this area probably contains considerable volumes

of Cndium as well. Because a large percentage of bed area grows near

the depth limit of Z n s t e r a growt.h, any decline in water transparency

will result in loss of large areas of eelgrass, making this an

ecologically sensitive area.

On the shore east. of the entrance to Lit-tle Harbor, eelgrass grows

in the troughs of sand waves, creating a distinct. banded pattern

observable on photographs. These beds show considerable movement

between photographs.

The lower limit of eelgrass is was difficult t.o delineate on the

photographs along the west side of Stony Point., Mashnee Island, and the

West Side of Toby Island and are partly approximated based on

bat-hymetry. Eelgrass grows along t.he margins of the Cape Cod Canal, but

these were not included in production estimates.

This part. of Buzzards Bay has become increasingly developed and

urbanized, and water quality has declines have been reported in some

areas such as shellfish bed closures in the Wareham River and Buttermilk

Bays due.to elevated coliforms. In But.termilk Bay near input-s of

nutrient sources, eelgrass grows to lesser dept.hs or may be absent, and

periphyt-on abundance is high (Costa, 1988, dosta and Valiela, in prep. .

Bourne: Wings Neck to Wegansett (Figs. 19 + 20)

Maps of eelgrass abundance in Bourne, south of Wings Neck were

based primarily on 1975, and 1981 aerial photographs and reports. No

satisfactory photograph coverage was obt.ained west of Scraggy Neck.

Zostera is abundant in this network of shallow protected harbors.

In low energy areas such as Red Brook Harbor and Wings cove, eelgrass is

dense and cont.inuous. On exposed parts of Scraggy Neck and Wings Neck,

eelgrass beds nearshore are dominated by algae covered rock and boulder.

The western tip of Scraggy Neck could not be interpreted clearly, but

eelgrass appears abundant beginning at the edge of the boulder fields

Falmouth: Megansett to West Falaouth Harbor (Figs. 21 + 22)

These maps were based on from 1972, 1975, 1980, 1981 aerial

surveys. The distribution of eelgrass in West Falmouth Harbor was based

on a 1979 low altitude survey and maps by Buchsba~.ln! (198.5).

Eelgrass is absent from along Silver Beach which may be due to the

strong wave action and longshore transport. apparent on photographs.

Water clarity is good in this part of Buzzards Bay because eelgrass

grows to 4.5 m MLW on most of the outer coast..

Accuml.11ated drift material and Rtrppia in West Falmouth Harbor make

interpretation of aerial photographs difficult, especially in npper

estuarine ares like Harbor Head. To adjust for algal cover, eelgrass

cnver was estimated as 50% of vegetated habitat area.

The deeper edge of eelgrass off Chappaquoit Pt. and the Falmouth

Cliffs follow the 3.6 to 4.5 m cont-our.

Falmouth: Chappaquoit Point to Gunning Point (Figs. 23 + 24)

Aerial surveys from 1975, 1978, and 1981 were used to make this

map. Field observations were made near Great Sippewisset Marsh.

This is a moderate energy environment with sand and rock covered

shores. In addition. numerous peat reefs occur nearshore along both

Little and Great Sippewisset Marshes. The deep beds offshore visible on

photographs (to 4.2 m MLW! are consistent with bathymetry but may

include rock fields. The percent cover of eelgrass beds in these and

ot.her rocky areas like Hamlin and Gunning Points (beds FAGU3, FAHP1,

FAHP2) were reduced by 30% cnver to account for rock and cobble fields.
