Ecology of the Rocky Mountains : ウィキペディア英語版 | Ecology of the Rocky Mountains (詳細はRocky Mountains are the major mountain range in western North America, running from the far north of British Columbia in Canada to New Mexico in the southwestern United States, climbing from the Great Plains at or below to peaks of over . Temperature and rainfall varies greatly also and thus the Rockies are home to a mixture of habitats including the alpine, subalpine and boreal habitats of the Northern Rocky Mountains in British Columbia and Alberta, the coniferous forests of Montana and Idaho, the wetlands and prairie where the Rockies meet the plains, a different mix of conifers on the Yellowstone Plateau in Wyoming and in the high Rockies of Colorado and New Mexico, and finally the alpine tundra of the highest elevations. These habitats are home to a great deal of wildlife from large grazing mammals such as the large herds of elk, moose and mule deer, smaller mountain goats and bighorn sheep, predators like black bear, grizzly bear, wolves, and coyote along with a great variety of small mammals, fish, reptiles and amphibians, hundreds of bird species, and tens of thousands of species of terrestrial and aquatic invertebrates and soil organisms.〔 Permanent human settlement of the Rocky Mountains has caused numerous species to go into decline, including species of trout, birds, and sheep. Gray wolves and grizzly bears have been completely eliminated from the United States portion of the range, but are returning due to conservation measures. ==Setting==
The Rocky Mountains range in latitude between the Liard River in British Columbia (at 59° N) and the Rio Grande in New Mexico (at 35° N), and in height up to the highest peak, Mount Elbert at , taking in great valleys such as the Rocky Mountain Trench. Precipitation ranges from per year in the southern valleys〔(【引用サイトリンク】work=Forest Encyclopedia Network )〕 to per year locally in the northern peaks.〔(【引用サイトリンク】work=Forest Encyclopedia Network )〕 Average January temperatures can range from in Prince George, British Columbia to in Trinidad, Colorado.〔
