Mount Elbert rises through multiple biotic zones, with alpine tundra at its peak.. 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 14,440 feet (4,400 m), taking in great valleys such as the Rocky Mountain Trench and San Luis Valley.
The Northern Rocky Mountains ecosystem in the United States is known by ecologists, biologists, and naturalists as one of the last areas of the contiguous United States that is relatively undeveloped enough and large enough to support a functioning ecosystem.
The Rocky Mountain ponderosa pine forest is a plant community at an elevation of 2,000–2,700 metres (6,600–8,900 ft) in the Rocky Mountains. [ 1 ] [ 2 ] : 89 It is an important temperate coniferous forest ecoregion , including some endemic wildlife and grass species that are only found in this ponderosa pine ( Pinus ponderosa ) habitat .
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 ...

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]
The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of 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]
