Section 7 Range

Under Section 7 of the Endangered Species Act of 1973, Federal agencies, or project proponents whose actions have a Federal nexus (e.g., Federal funding, permit, or lease), must consult with the U. S. Fish and Wildlife Service if their actions “may affect” listed species (endangered, threatened, proposed, candidate) or their habitat.  Section 7 species ranges identify those areas on the landscape where agencies or proponents should consider potential effects, both direct and indirect, to the species and their habitat.  These Section 7 species ranges typically encompass larger areas than specific locations where listed species are known to occur.  Project proponents are encouraged to refer to the Service’s Information, Planning, and Conservation System (IPAC) website at http://ecos.fws.gov/ipac/ or to contact the FWS Wyoming Ecological Services Office for additional information http://www.fws.gov/wyominges/ :307-772-2374.  (Section 7 Range boundaries based on the best available data at time of development.  Section 7 Ranges will be updated as new information becomes available.)

Species Information

The Wyoming toad (Bufo (Anaxyrus) baxteri) historically occupied flood plains, ponds, and seepage lakes associated with shortgrass communities occurring between 7,000 and 7,500 feet in elevation in the Laramie Basin.  The toad was associated with both the Big and Little Laramie Rivers.  Populations of the Wyoming toad suffered a dramatic decline in the 1970s and the current distribution is limited to Mortenson Lake National Wildlife Refuge and possibly Hutton Lake National Wildlife Refuge.  The Service recommends surveys when a proposed project will occur within 1-mile of Mortenson Lake or Hutton Lake National Wildlife Refuges.  These guidelines may change as new sites for Wyoming toad populations are established.
