Remarkable Ocean Habitat Faces Mounting Threats

Cashes Ledge is an extraordinary underwater mountain range located 90 miles off New England’s coast in the Gulf of Maine. This special place faces threats from climate change and damaging human activities. It deserves to become a National Marine Sanctuary. 

CLF in Action

The Gulf of Maine is warming faster than most of the world’s oceans. Now, more than ever, it needs a fully protected marine area, which scientists say is more resilient to the effects of climate change. Because of its noted ecological and scientific importance, Cashes Ledge should fill this role. Setting aside some ocean areas with strong protections is critical as New England begins to understand how to respond and rebound from climate change. 

CLF has fought to protect Cashes Ledge for over a decade. But the area’s existing protections are not permanent. We must work with stakeholders across the region to fight for sanctuary status for this remarkable place. 

What’s at Stake

The exquisite kelp forest, steep ridges, and deep basins of Cashes Ledge create unique and vibrant habitats for species both common and rare to thrive. This mix of diverse marine life and largely undisturbed habitat also makes Cashes Ledge an ideal open-sea laboratory for scientists to learn about the health of New England’s ocean. 

The rate at which the Gulf of Maine is warming puts New England’s economy and ecological assets at risk. Shellfish and groundfish populations are already struggling from changes in habitat and food availability, and some are already moving away from their typical habitats in search of cooler waters. Sanctuary status for Cashes Ledge would provide a haven for diverse marine life to thrive. Sign our petition to join the fight to ensure this special place is preserved for generations to come.
