Citizen Science

2019 International Coastal Clean-up:

In October 2019, Clinton Avenue School student volunteers helped with this year’s International Coastal Clean-Up at two specific New Haven Long Island Sound sites. The first was at Fort Nathan Hale Pier along with the US Coast Guard and the second was at New Haven Land Trust’s Long Wharf Preserve. Students helped to collect trash and also to record data on the types and amounts of trash collected at those two sites. The data was then added to the world wide database to help scientists understand how trash is impacting our oceans and coastlines.

Project Limulus Additional Info:

Since 2006, the Branford Land Trust has assisted Sacred Heart University with Project Limulus, a horseshoe crab study. The Land Trust helps coordinate the volunteers that conduct surveys on Branford beaches. Project Limulus, started in 1998, has conducted multiple studies focusing on the life history of the American horseshoe crab population living in Long Island Sound.

During the 2013 spawning season, approximately 800 horseshoe crabs were tagged by approximately 35 Branford Land Trust volunteers. In addition, horseshoe crab eggs were raised in two classrooms in Branford public schools.
