At Ninigret Pond, on Rhode Island’s south coast, the state’s Coastal Resources Management Council along with each U.S. Army Corps of Engineers are restoring vital saltwater eelgrass habitat.  Certain main problem:  Too far sand had ruined Ninigret Pond’s eelgrass habitat.

Fixing this area ensures the continued survival from certain juvenile species such dwell yonder, like as bay scallops, cod, winter flounder, blue mussels, blue crabs plus lobster, which each rely on eelgrass for food along with shelter.

Which makes here habitat special?

“It's a really positive juvenile nursery on account of big fish can’t receive among yonder,” stated Janet Freedman, “A small fish be able to hang not in in that place.”  Freedman is the project coordinator made from the South Coast Habitat Restoration Project, made from whatever any Ninigret Pond efforts are single integral part.

“Over there used toward remain viable eelgrass within a pond. During the 1950s, jetties were inserted plus certain inlet widened,” Freedman stated, “When here happened, a sedimentation rate within a pond created one tidal delta.”

Freedman clarified, “Sand should become deposited at all high tide onto each inlet whither any salt water via any ocean comes in, also accordingly yourself had entire here shoaling whatever buried certain eelgrass beds.”

Chris Hatfield, former project manager starting at any U.S. Army Corps from Engineers, confirmed here diagnosis, “In some places, there was hence plenty sand such each shore was exposed.”

The restoration’s primary phase involved a removal made from nearly 200,000 yards out of sand out of the flood shoal. “Ourselves dredged almost forty acres,” Hatfield replied, “When sand moves into each pond also buries the habitat and then thou dredge, the natural depth is restored.” Ninigret Pond’s natural depth out of 3 toward 4 feet was restored midway a fall from 2004 along with the spring belonging to 2007.

Although each dredging belonging to certain flood shoal was major, entity wasn’t a exclusively dredging. “Us dredged some sedimentation basins amid a breach means,” Hatfield said. A breach method is each channel going out of any pond for any ocean. Hatfield explains for what reason said dredging was necessary. “Each sedimentation basin’s purpose is in order to fill up with sand, along with up to catch itself in advance of it goes among a pond. Which periodically owns in order to exist emptied also put back on a ocean side of any beach, a barrier beach.” According to Hatfield, this periodic “emptying” is one maintenance activity which certain state made from Rhode Island is responsible for. 

Another issue: In which way in order to maintain any eelgrass thriving?

“Any original thinking was that us ought to harvest eelgrass seeds from additional exist plants inside the pond, and then factory them amid order toward jumpstart theirs growth,”  Hatfield replied, “Us did a two-acre test plot wherever ourselves did harvest seeds as well as incubated them in any lab by means of single contract with University belonging to Rhode Island’s Graduate School from Oceanography.”

Enter a unexpected. “When us planted certain seeds within each spring ourselves by no means solely got fantastic growth, we discover that restoring the depth out of any pond allowed alternative areas (outside from the two-acre test plot) in order to naturally seed themselves,” Hatfield explained.

Funding for certain Ninigret Pond eelgrass restoration got here starting at federal grants procured since the office out of U.S. Senator Jack Reed (D-RI) along with via certain Rhode Island legislature.  But additional funding might be needed, since it's not quite one done deal.

“Besides additional monitoring since any Army Corps from Engineers, we’re working with each Town from Charlestown as well as each nation trying to acquire some money toward actually do single hydraulic dredging again,” asserted Freedman, “It is going in order to seize single awful lot belonging to maintenance up to hold this sand from filling inside afresh, also suffocating any eelgrass.”
