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]

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 tree was climbed on October 13, 2011, by Ascending The Giants (a tree-climbing company in Portland, Oregon) and directly measured with tape-line at 268 ft 3 in (81.77 m) high. [ 23 ] [ 24 ] As of 2015, a Pinus lambertiana specimen was measured at 273 ft 9 + 1 ⁄ 2 in (83.45 m), [ 25 ] which surpassed the ponderosa pine previously ...
