Ecosystems: savanna like, sometimes close to open forests with mostly Ponderosa pine, sometimes Douglas-fir on more moist sites, are winter habitats for elk, Bighorn sheep,white-tailed and mule deer as well as numerous birds, due to location between Great Basin in the south and boreal forest in the north some birds like Gyrfalcon and Snowy Owl have their southern migration limit in this area and other like Canyon Wren have their northern migration limit here, also the breeding habitat of endangered bat species,
wetland meadows and ponds are home to variety of insects, amphibians and reptiles, fire occurs every 15-20 years and only burn understory, Ponderosa Pine bark is especially thick to protect the tree from burning<\/p>\n\n\n\n
