Who We Are
Founded in 1982, we are a private, non-profit organization of island residents and other interested citizens.
We work to conserve wild or undeveloped open space, scenic areas, and historic landmarks in the Casco Bay region.
We strive to balance human use and enjoyment with protecting the natural environment of Casco Bay for future generations.
Invasive Marine Species
The presence of invasive species often indicates changing ecosystems. See our new Invasive Marine Species page with informative links on these species in the Casco Bay region.
