Mid-Coast Audubon and Camden Public Library will offer a free online Zoom presentation on the ecology of horseshoe crabs in the Great Salt Bay Thursday, April 15 at 6 p.m. To register for the event, email Julia Pierce (jpierce@librarycamden.org) to request the Zoom login information.

The Great Salt Bay in Damariscotta hosts one of the best breeding locations for horseshoe crabs (Limulus polyphemus) in the state of Maine. Since 2003, taking and possession of horseshoe crabs has been prohibited in the state due to their small populations. The presenter, Sarah Gladu, will illuminate these ancient animals, their habits, their conservation status in Maine, and their importance to the overall health of our estuarine environment.

Gladu is the director of Education and Citizen Science for Coastal Rivers Conservation Trust in Damariscotta. She has been running their School for Field Naturalists program since 2005 and has worked in environmental education since 1992.
