Wellfleet Bay's Conservation Work

Wellfleet Bay Wildlife Sanctuary is actively involved with a variety of research projects that relate to wildlife monitoring, research, restoration, and conservation on the Outer Cape. Many of the projects focus on endangered or threatened species, or those that have declining populations. Current, on-going projects include:

  • Protecting terns and plovers in the Coastal Waterbird Program
  • Monitoring diamondback terrapins
  • Surveying horseshoe crabs
  • Mapping Osprey nests
  • Banding songbirds
  • Rescuing sea turtles

While we have dedicated science staff, the efforts of community science volunteers provide critical support to our science department, as well as to the wildlife themselves.

Wellfleet is home to the most northerly population of the Diamondback Terrapin (Malaclemys terrapin). Through our conservation work, we hope to protect this enigmatic species and the salt marshes it calls home. Learn More >

Group of horseshoe crabs

Horseshoe crabs have been crawling ashore on Cape Cod to mate on full moon nights for about 350 million years, and Mass Audubon seeks to ensure this ancient rite of spring continues. But increased harvesting of these fascinating animals threatens their population. Please volunteer today to help preserve these very special creatures.
