Maine DEP 2018 and 2022 Eelgrass Mapping

These two maps show the decline of eelgrass in Casco Bay over just four years. In 2018, Casco Bay’s eelgrass was mapped by Maine Department of Environmental Protection, revealing an extensive network of eelgrass beds. But four years later, when mapped again in 2022, 54% of all eelgrass beds in Casco Bay had disappeared – a huge loss in a short amount of time.
