Wyoming Ecological Services Field Office
Cheyenne, WY
(307) 772-2374

The Wyoming Ecological Services Field Office provides biological advice to other federal and state agencies, industry, and members of the public concerning the conservation of fish and wildlife and their habitat that may be affected by development activities. Personnel assess the potential effects of projects to migratory birds, endangered species, anadromous fish, and wildlife. In Wyoming, these projects typically include activities such as agriculture, mining, utility lines, dredge and fill activities, dam and reservoir operations, oil leasing, and highway construction. The effects of contaminants on fish and wildlife are also assessed. Recommendations are then made regarding ways to avoid, minimize, or compensate for harmful impacts on fish and wildlife resources and their habitats. The primary areas of responsibility for the Wyoming Ecological Services Field Office include, contaminant assessments, endangered species, Federal project reviews, and wetlands conservation.
