Cashes Ledge harbors the largest, deepest kelp forest on the eastern seaboard.

Eighty miles off the coast of Cape Ann, Massachusetts, lies one of New England’s most spectacular ecological treasures. Cashes Ledge, an underwater mountain range, supports some of the most diverse, dynamic, and productive habitat in the Gulf of Maine, including the largest and deepest kelp forest in the region and possibly in the North Atlantic. Because this area has been protected from bottom trawling for almost 15 years, the kelp forest and its related complex rocky bottom habitat harbors some of the largest and most productive fish in the region. Cashes Ledge is exactly the type of habitat scientists say we should protect if we are to ever restore the grossly depleted Atlantic cod. But now, Cashes Ledge is at immediate risk of being opened to destructive bottom trawling.

Cashes Ledge deserves protection. Please sign our petition asking NOAA to maintain protection for the entire Cashes Ledge area.

The steep ridge of Cashes Ledge rises sharply from the seafloor, from the ocean basin at 600 feet beneath the surface to the high peak of Ammen Rock at just 40 feet from the surface waves. This unique bathymetry creates a phenomenon known as internal waves, which carry nutrient-rich cold waters up from the depths to the warm and sunny surface. This mixing creates ideal conditions for spectacular primary productivity, which in turn supports a rich community of marine wildlife.

The kelp forest and rocky sea floor of Cashes Ledge aren’t the only important places in this area. To the west and north, Fippennies Ledge and Sigsbee Ridge link with Cashes Ledge to form an extensive, horseshoe-shaped suite of productive habitat. In the middle of this horseshoe, a muddy basin gathers the nutrients that fuel this vibrant community. The slopes down to this basin support an incredible diversity of marine ocean life from lush mussel beds to fields of anemones, and even a rare blue sponge.

The incredible abundance of this area also supports migrating North Atlantic right whales, sea turtles, blue and porbeagle sharks, bluefin tuna and the increasingly rare Atlantic wolffish. Such an abundant and diverse array of marine life in a relatively small area makes Cashes Ledge an ecological marvel.

In recognition of the remarkable value of this habitat, the New England Fishery Management Council closed the area around Cashes Ledge to damaging bottom trawling and scallop dredging nearly 15 years ago. This protected status allowed previously trawled habitat areas to recover and has supported the health of juvenile and spawning fish. It has also allowed Cashes Ledge to serve as an underwater laboratory for numerous marine scientists, providing an opportunity to study ecosystem functioning and biodiversity in a rare environment that is isolated from the polluted waters of coastal habitats and less impacted by commercial fishing.

But now, near the end of an eight-year process to develop a comprehensive habitat plan for New England’s fisheries, the New England Fishery Management Council voted to eliminate protection for nearly three quarters of the Cashes Ledge protected area.

The NEFMC's current proposal would eliminate protection for nearly three quarters of the current protected area around Cashes Ledge.

Despite the chance to maintain protections for all of Cashes Ledge, the commercially-driven Fishery Management Council voted to eliminate protections for about three-quarters of the Cashes Ledge protected area. Despite overwhelming evidence of the ecological value of this area, and despite a legal requirement “to minimize to the extent practicable the adverse effects on such habitat caused by fishing and identify other actions to encourage the conservation and enhancement of such habitat,” the Council voted to eliminate protection for all areas except a small sliver around Ammen Rock and the peak of the ridge, but open Fippennies Ledge, Sigsbee Ridge, and Cashes Basin to destructive trawling and dredging.

The final decision will not likely be made until September, but we now have the opportunity to tell the Council and NOAA that eliminating protection for some of the best habitat in the Gulf of Maine is the wrong way to go. NOAA will soon announce a formal comment period on the proposal, including a series of public hearings around New England, and we’ll provide updates as this comment period and public hearings are announced. But why wait? Cashes Ledge deserves protection. Please sign our petition asking NOAA to maintain protection for the entire Cashes Ledge area.

    Cashes Ledge may be one of the last remnants of New England’s prehistoric ocean. Careful scientific studies have indicated that to properly protect areas like Cashes Ledge and to understand the workings of a “scientific reference site” that is unfished and unaltered, a larger buffer area must be created so marine life can move freely in and out of the highest value areas. The Cashes Ledge area is only 532 square miles of the 36,000 square mile Gulf of Maine, a pittance for the insatiable fishing industry but a treasure trove of New England’s natural marine history.

      It’s sad that I have to return home after spending two days in in Washington DC seeking legislative support for ocean planning, then get up the next day to present at a day long climate change expo here in Maine, only to read that I’m just one of the bad guys; the commercial, the insatiable, the fishermen. Please Peter, this tactic of presenting your case is getting old, as well as becoming non productive. If we’re truly seeking the long term habitat protection the Gulf of Maine deserves, it’s time to leave the “good guy, bad guy” stuff for the old t.v. shows.

      • Peter Shelley

        Richard, I respect your perspective in this arena, your contributions to solutions, and your vision for a better future. Having said that, I have been going to the mike at fishery council meetings for more than 24 years–it’s gotten “old” for me more than a decade ago–and talking about stewardship and science-based fisheries management–including advancing the conservation benefits of large closed areas that marine scientists promote. The folks who represent the commercial fishing industry in those council settings do not want to seriously discuss issues of long term habitat protection. They want to open as much new bottom as they can even though cod have completely crashed. That is the real zero-sum world I seem to live in. I would seriously love suggestions about how to shift that in the more productive directions you suggest.

        • Richard Nelson

          I certainly don’t envy you in your years of frustration at the council meetings and would hope and trust that, being a good person and having strength of spirit, you would not have lost faith in all fishermen. Recently at the Maine Fishermen’s Forum the NEFMC’s Michele Bachman gave a presentation on the Habitat Omnibus Amendment. Although it was an excellent talk, it left me asking, especially as one involved in ocean planning, where the real Habitat was? It sounded like they’re based on single species stock assessments, areas of juvenile fish and spawning grounds. I would think that they, or someone, has to start by researching and mapping habitat in a holistic ecosystem based manner. Otherwise they will remain just a fisheries management tool that might be opened or closed as the managers see fit, and not really suitable for ocean planning or thinking in terms of MPAs.

    Cashes Ledge is completely full of lobster traps.

    Hundreds of thousands of rusting traps on the bottom right on the ledge, and more every year.
    Rotting bait fouling the bottom.

    Its no oasis. Its a landfill.

  3. Brenda Troup

    Protect this area completely. We don’t have to foul every last bit of ocean, or land, for that matter.
    We will benefit in the long run from thriving places.

    At one time Cashes Ledge was identified as a potential marine sanctuary or protected area. However, ocean planning as well as NEPA project impact documentation are not well received by government agencies nor supported at the level required to be successful. Planning in general is not even considered a legit career field by many upper level management in government. The missions and goals/purposes of our national parks, wildlife refuges, marine sanctuaries,and wilderness areas are all under attack and their programs underfunded. The Stellwagen Bank Marine Sanctuary is an example of improper planning and management. To the agency and program congressionally mandated to protect it continues to resist any attempt at regulations or limits on known incompatible uses especially commercial fishing operations. Protection of ocean fish habitats and unique areas such as Cashes Ledge along with most recommended commercial fish stock regulations or management strategies are met with protests. We have taken a giant step backwards in ocean conservation over the past thirty years. The efforts of other countries have succeeded our own in creating MPAs and regulation of fishery operations.
