OysterShellTrailerH4HLogo12v2.1Half Shells for Habitat (H4H), which was initiated by Seatuck and a host of partners in 2018, is an island-wide program to recover oyster shells from restaurants for use in oyster and habitat restoration efforts.  

Maureen Dunn, Seatuck's Water Quality Scientist (pictured at right with Seatuck board member Charlie Weiss), conceived and established the program to address the critical need to return oyster shells to Long Island's estuaries. The shells provide vitally important substrate on which young oysters can attach and grow, and they help to combat coastal acidification by returning calcium to the water (see diagram below for more detail).

Seatuck initially partnered with the Town of Brookhaven to launch the program. With Town Supervisor Edward Romaine's enthusiastic support, a shell storage site was established at their composting facilty in Manorville (pursuant to NYSDEC regulations, after being collected the shells have to sit in the sun for at least 6 months before going back in the water).

And the project was piloted with the generous cooperation of Catch Oyster Bar in Patchogue and three of the Bohlsen Restaurant Group's restaurants:Tellers (Islip), H20 (East Islip) and Prime (Huntington). The Snapper Inn (Oakdale) and The Cull House (Sayville) also joined the program as early participants. 

H4H has continued to grow since the pilot project, with the Town of Islip also coming on board as a parter and establishing a shell storage site at their recycling and compost facility. And the full list of participating restaurants has expaned to including the following:

  • Bluepoint Brewery
  • Captain Bill's
  • Catch Oyster Bar
  • Claws Seafood Market
  • The Cull House
  • H2O
  • Harbor Crab
  • Prime
  • The Snapper Inn
  • Tellers
  • The View

Importantly, Seatuck's program wasn't the only shell recovery project iniated on Long Ialnd in 2018. At around the same time as H4H was getting started, the Town of Hempstead and Adelphi University were launching a program of their own in southern Nassau County. Their program, call Community Oyster Restoration Effort (CORE) and partially supported by a grant from New York State, also began collecting shells from restaurants in Long Beach and nearby communities in 2018. Seatuck and the team at CORE have been working together closely and will be coordinating their efforts under the H4H banner. 

Half Shells for Habitat reached an important milestone in late May 2019, when fully-aged shells were picked up at the Town of Brookhaven's storage site by both Cornell Cooperative Extension and Stony Brook University's Shinnecock Bay Restoration Program Harbor for use in their oyster  restoration and reef-building programs.

Growth of the program will now depend on its ability to attract volunteers to help Seatuck add and manage new participating restaurants. Volunteers are needed to deliver/collect buckets from the restaurants, clean buckets and make deliveries of shells to the storage site.
