The month of May kicks off survey seasons for two groups of federally endangered and threatened species: freshwater mussels and bats. Projects located within the range of these protected species may require coordination with the U.S. Fish and Wildlife Service. EnviroScience biologists routinely work with federally endangered and threatened species, such as the Indiana bat, gray bat, northern long-eared bat, sheepnose mussel, rayed bean mussel, northern riffleshell mussel, snuffbox mussel, rabbitsfoot mussel, fanshell mussel, and dwarfwedge mussel, along with many others.

Early coordination is crucial for avoiding project delays and other restrictions. Our team has extensive experience coordinating project clearance and completing Section 7 consultations. EnviroScience has completed both large and small projects for the transportation industry, military facilities, utility corridors, large mining sites, the railroad industry, the oil and gas industry, the coal industry, and private development.

Mussel Survey

Mussel survey season dates are specific to your state but generally are limited to May through October, and early initiation of coordination with agencies will ensure your project is completed in a timely manner.
