               Fort Huachuca’s significant wildlife
           diversity is directly related to the habitat
           diversity in the region.       Biotic diversity
           mirrors similar habitats outside installation
           boundaries.       Various inventories have
           confirmed the occurrence of almost 500
           birds, and a variety of mammals, reptiles,
           and amphibian species on the installation.
