The United States Fish & Wildlife Service (USFWS) has proposed federal protections for the salamander mussel, a small freshwater bivalve facing challenges across its habitat range spanning 14 states, from New York to southwest Arkansas.

While the salamander mussel may not capture headlines like other charismatic species, it plays a significant role in maintaining the health of our rivers and streams.

A Species in Peril

The USFWS's "species status assessment" indicates a grim reality. Over 80% of the 66 known populations of salamander mussels in the United States are at "high risk" due to various environmental threats. An additional 14% face moderate risks, including water contamination, changes in water flow, landscape alterations, invasive species, and risks to the mussel's host species, the mudpuppy salamander.

Unsung Ecosystem Engineers

“Freshwater mussels are considered ‘silent sentinels’ of rivers and streams. Where mussels thrive, water quality tends to be good. Where mussels are declining, it’s an indication that rivers and streams they inhabit may be unhealthy,” the USFWS maintains. “In addition to being indicators of stream health, mussels can keep the water clean by filtering their food from the water, and with it, sediment and other pollutants.”

The USFWS has identified around 2,012 miles of rivers and streams as "critical habitat" for the salamander mussel. If these waterways receive the critical habitat designation, habitat restoration projects, such as stream bank stabilization and culvert replacements, may face added regulatory complexities.

Conservation Efforts and Regulatory Considerations

While the potential ESA designation for the mussel's habitat could introduce additional regulatory requirements, several conservation organizations are committed to collaborating with the USFWS to protect endangered species.

“In Virginia, the ESA listing for the Roanoke log perch helps shape the trout management protocols of the Virginia Department of Wildlife Resources,” Mark Taylor, Eastern Communications Director for Trout Unlimited (TU), told Field & Stream. “They’re not stocking predatory brown trout, for example, in watersheds that have those endangered fish.”

The salamander mussel reminds us of the unseen heroes in our natural world. While they may lack the glamour of larger mammals or colorful birds, their significance cannot be understated.

Protecting these fragile species is a commitment to safeguarding our ecosystems and the future of our planet. The time for action is now, to ensure that the gentle presence of the salamander mussel is not lost forever.
