The highest number of different species (species richness) occurs in the Black Hills in northeastern Wyoming and in the Laramie range and eastern Great Plains. Species richness is also high along streams and adjacent riparian areas where vegetation is strongly influenced by the presence of water. Because the climate is dry in most parts of Wyoming, wet areas such as streams, lakes, wetlands, and riparian areas are crucial habitat for many animals. They comprise less than 4 percent of Wyoming’s land area but provide habitat for over 80 percent of all vertebrate species in the state, including the three species shown below.
