What they reported doing

  1. #1 primary $66K
    OYSTER REEF CIOR has been funded to select two sites for oyster reefs from five potential locations around the island that were identified by an extensive survey of existing oyster populations around City Island. CIOR monitored the five sites and the data on oyster growth and mortality from those sessions was used to inform the selection of the two sites. The plans and designs for the oyster reefs at those sites are now being presented for sign-off and permitting. Now that the two sites have been selected, specially engineered structures will be put in place, and cured shell material will be added in order to promote reef formation. In addition, CIOR has partnered with local City Island restaurants to collect their discarded shells in 32-gallon bins and bring them to a curing site at the Pelham Bay Landfill. The shells are placed on the grass-covered soil on top of one another to a height of two feet and regularly turned to provide sufficient airflow. No chemicals are used in the curing process, which takes up to twelve months.

How they approach the work

Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.

  • Natural Shell Curing Process
    methodology: natural_shell_curing
    By curing oyster shells through a natural, chemical-free method involving stacking and aeration, we prepare sustainable reef materials because this process supports ecological integrity and avoids introducing harmful substances into marine environments.
  • Science-Based Site Selection
    methodology: science-based_site_selection
    By using ecological monitoring data on oyster growth and mortality, we select optimal sites for reef restoration because data-driven placement increases the likelihood of reef survival and long-term ecosystem impact.
