The ecology of the Rocky Mountains is diverse due to the effects of a variety of environmental factors. The 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 1,800 feet (550 ...
Spruce-fir forest in the Canadian Rockies. The Rocky Mountains subalpine zone is the biotic zone immediately below tree line in the Rocky Mountains of North America.In northern New Mexico, the subalpine zone occupies elevations approximately from 9,000 to 12,000 feet (2,700 to 3,700 m); [1] while in northern Alberta, the subalpine zone extends from 1,350 to 2,300 metres (4,400 to 7,500 ft).
As stated in an article from Montana State University in its Institute on Ecosystems: "An ecosystem can be small, such as the area under a pine tree or a single hot spring in Yellowstone National Park, or it can be large, such as the Rocky Mountains, the rainforest or the Antarctic Ocean."
A subalpine lake in the Cascade Range, Washington, United States. Montane ecosystems are found on the slopes of mountains.The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify.

The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. [1] It is located within the northern Rocky Mountains, in areas of northwestern Wyoming, southwestern Montana, and eastern Idaho, and is about 22 million acres (89,000 km 2). [2]
In contrast with Rocky Mountain ecoregions to the north, lodgepole pine is rather rare, replaced by ponderosa pine and quaking aspen. [4] Rocky Mountain Douglas-fir, Engelmann spruce, subalpine fir, limber pine and Gambel oak can also be found in the mountain forests. [5] Bristlecone pine is the dominant plant at the tree line/krummholz zone. [4]
The Rocky Mountain Front is a somewhat unified geologic and ecosystem area in North America where the eastern slopes of the Rocky Mountains meet the plains. [1] In 1983, the Bureau of Land Management called the Rocky Mountain Front "a nationally significant area because of its high wildlife, recreation, and scenic values". [2]
