Final Environmental Assessment Approved for Implementing Candidate Conservation Agreements for Eastern Massasauga in Mid-Western States

The final Environmental Assessment (EA), which considered various ways to protect the eastern massasauga rattlesnake (Sistrurus catenatus catenatus, hereafter massasauga), was approved on July 26, 2005 when a Finding of No Significant Impact (FONSI) was signed.  Alternative A, which provides for implementing CCA’s or CCAA’s for the massasauga on protected lands (e.g., state property) throughout Region 3 and was the Service's Preferred Alternative, was the alternative selected.

The massasauga is a Federal candidate species for listing under the Endangered Species Act of 1973, as amended. The purpose of the EA was to evaluate the environmental consequences of implementing different strategies for conserving the remaining massasauga populations in Region 3.  The FONSI, final EA and appendices are provided below.  A printed copy of the final EA can also be requested by calling (612) 713-5343, by e-mailing to, or by writing to: Peter Fasbender, U.S. Fish and Wildlife Service, Ecological Services, 1 Federal Drive, Fort Snelling, MN 55111-4056.
