The protection of high-quality freshwater mussel habitat is a top priority for the conservation of freshwater mussels. Protection of existing stable populations and stabilizing declining populations are focal areas for many mussel species nationwide. Federal legislation like the U.S. Clean Water Act, Endangered Species Act, and National Environmental Policy Act provide some protection; however, many smaller isolated stream sections, which may hold more mussel resources than mainstem rivers, will go unprotected. Dam removal and restoration of channel complexity are two examples of habitat restoration actions that have potential to positively influence mussel populations in the long term, though mussels are rarely studied or monitored during and after these activities.
Generally, habitat restoration as practiced by the CTUIR through River Vision can create habitat conditions beneficial to mussels. The habitat restoration process requires coordination and communication between the CTUIR Freshwater Mussel Research and Restoration Project and habitat restoration professionals to ensure the protection of existing mussels, salvage and relocation of mussels in danger (only when absolutely necessary), and/or monitoring of mussel response to actions during and after project implementation. While the CTUIR Mussel Project does not prescribe habitat restoration specific to mussels, habitat projects that generally increase the river complexity and floodplain connectivity will benefit mussels in the long run.
