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 are important habitat for a great deal of wildlife, such as elk, moose, mule deer, white-tailed deer, pronghorn, mountain goat, bighorn sheep, black bear, grizzly bear, gray wolf, coyote, cougar, bobcat, Canada lynx, and wolverine. [1] North America's largest herds of moose is in the Alberta-British Columbia foothills ...
On coasts and isolated mountains, the tree line is often much lower than in corresponding altitudes inland and in larger, more complex mountain systems, because strong winds reduce tree growth. In addition, the lack of suitable soil, such as along talus slopes or exposed rock formations, prevents trees from gaining an adequate foothold and ...

Rocky Mountain Douglas-fir is a large tree, typically reaching 35–45 m (115–148 ft) in height and 1 m (3 ft 3 in) in diameter, with exceptional specimens known to 67 m (220 ft) tall, and 2 m (6 ft 7 in) in diameter. It commonly lives more than 500 years and occasionally more than 1,200 years.
The dominant vegetation type of this ecoregion is coniferous forest, composed mainly of ponderosa pine (Pinus ponderosa), Rocky Mountain Douglas-fir (Pseudotsuga menziesii subsp. glauca), subalpine fir (Abies lasiocarpa), Engelmann spruce (Picea engelmanni) and trembling aspen (Populus tremuloides), with limited populations of limber pine (Pinus flexilis).
