Maine Rockweed Coalition

Promoting conservation of intertidal marine habitat.

Mission: The 501c3 Maine Rockweed Coalition promotes conservation of intertidal marine habitat, including rockweed.

  • We are biologists, teachers, Maine residents, small business owners, fishermen, and others. We became a 501c3 non-profit in 2021.

  • We believe in the value of protecting coastal habitat for fisheries and wildlife, particularly in light of the impacts of climate change on marine species; and for climate mitigation. 

Dr. Ken Ross (1937 – March 6, 2024). Founding board member. Plaintiff in the landmark Ross v Acadian Seaplants case, which resulted in landowners having the legal right to deny rockweed harvesters access to the rockweed on their intertidal property.
