Coniferous forests, dominated by cone-bearing trees like pines, firs, and spruces, are the most common forest type found in the Rocky Mountains.

The Rocky Mountains are characterized by extensive coniferous forests. These forests are dominated by evergreen trees such as pine, fir, spruce, and Douglas-fir, which are well-adapted to the cold winters and varying elevations of the region. These trees' needle-like leaves and cone structures help them conserve water and withstand harsh weather conditions, making them ideally suited to the Rockies' climate.
