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.

NEW 2024 publication! (OPEN ACCESS)

New peer-reviewed paper in the Journal of Experimental Marine Biology and Ecology by MRC senior scientist and three others is a critique of the 2023 paper concluding that rockweed grows back rapidly, a year after commercial harvest.

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. We remember Ken with gratitude and affection.
