CCC Shoreline Restoration Project DWQ Project #050589
Monitoring done in 2010
SAV/benthic monitoring was done by dive master and commercial fisherman, Mark
Hooper, who also did our previous SAV monitoring Using SCUBA he sampled the
eastern embayment for sea grasses and he counted worm tubes Sea grass was sampled
every square meter along the transect lines, worm tubes were sampled every 5 meters
The main cove was surveyed for SAV on July 22, 2010 and August 3, 2010 The
remainder of the cove was sampled for worm tubes on August 23, 2010
The sampling grid consisted of 6 lines spaced 5 meters apart The deepest line ran
between the centers of the rock jetties, the other lines ran parallel to this initial line The
grid was set our using a tape measure and a wreck reel with the line marked every meter
Our recording slates had a meter stick attached to them Samples were taken on each
side of a sample line
They found two patches of Zostrea in relatively shallow water One patch was
larger (13 sq m) and dense, the other was about 4 sq in These patches were not present
when the cove was sampled 2 years ago Hooper also noted single rooted sprigs in the
area, as well as some mats of dead grass, presumably due to net pulls in the area Hooper
spoke with Jud Kenworthy from NOAA, who stated that in general the eel grass Zostrea
had some mortality with high summer water temperatures
The abundance of worm tubes was a significant finding The worm tubes are
thought to be Diopatria cuprea There were thousands of these in the embayment —new
since the project was built in 2006 On the spreadsheet with worm tube counts there is an
estimate for total numbers for the cove The table below (from the spreadsheet) explains
the method used to make the estimate

SUM The total number of worm tubes counted on the transect, either NE or SW of the
line Worm tubes were counted every 5 meters
Sq M counted The number of square meters counted along a transect line
Sq M Total The total length of the transect line in meters Yellow lines on the chart
were counted, red squares are an estimate of the water edge

Worms /sq M Average worms per sq meter counted Calculation = (SUM divided by
Sq M counted)
Total worms Estimate of the total number of worm tubes for the entire transect
Calculation = (Worms /sq meter X Sq M Total)
Ave worms The average of the sampling on either side of the transect line
Differential This is used to make an estimate of worm tube abundance for the area not
sampled between the transect lines This is used to calculate the total number of worm
tubes in the cove Calculation Determine the difference between the average worm
counts on two adjacent transect lines Divide by 4, this the differential, add this to the
unsampled "transects" between the sample lines
In the chart, RED numbers are estimates The formulas are embedded in the chart on the
spreadsheet
Planted marsh grass survival and density monitoring
Survival and density of marsh grasses Spartina alterraflora and Spartina patens were
surveyed by two classes of Environmental Biology students from the College Students
were trained to do transects using a field tape measure and meter quadrats Groups were
assigned to survey the eastern and western planting terraces as well as the BMP site
From their data (see attached spreadsheet), the density of S patens on the planting
terraces was 62 stems per sq in (avg 77 on eastern terrace and 47 western), the density of
S alterncflora on the terraces was about 20 stems per sq in (only along waterline)
In the BMP there is a mixture of SA, SP and many other brackish plant species The
BMP is now completely dense with vegetation, both planted and "volunteer" species In
addition, the site has become a magnet for wading birds and other wildlife
Attachments 3 spreadsheets with marsh grass density, SAV and benthic data
