Improving and protecting the environmental health of Casco Bay.
Eelgrass meadows in Casco Bay declined in size by 54 percent between 2018-2022, a loss described as “staggering” by the Maine Department of Environmental Protection in a January 2023 report. Many factors can contribute to loss of eelgrass. Nitrogen pollution is one of them, and unlike other contributing factors such as warming water temperatures, the amount of nitrogen in the Bay can be controlled at a local level.
