The Long Island Coastal Bioblitz is hosted by Seatuck Environmental Association, Long Island Sound Study, Peconic Estuary Partnership, South Shore Estuary Reserve, New York Sea Grant and Long Island Invasive Species Management Area. One of the goals of the island-wide bioblitz is to better understand the ecological community and biodiversity around Long Island’s vitally important estuaries.

What is a “bioblitz”?

A bioblitz is a community science effort to record as many species as possible within a designated location and time period. Using the free iNaturalist app, you can record all of your observations from birds to plants!

Seatuck, LISS, PEP, SSER, and LIISMA have put together the Long Island Coastal Bioblitz to engage the community in exploring all of Long Island’s incredible habitats and the species that inhabit them.
