Trees and Shrubs
One of the most fascinating aspects of Bighorn Canyon National Recreation Area are the diverse species of trees and shrubs found in a relatively small area. There are three major groups of plants in the park:
Each of these groups contains trees and shrubs that thrive in extreme conditions.
The Rocky Mountain plant group dominates the central and northern areas in the park. Shrubland in this climatic zone gives way to limber and ponderosa pines. On Black Canyon's north facing (shadowed) slopes Douglas Fir can be found.
At the north end of the recreation area, Great Plains species are abundant. They require greater moisture then species to the south. Most prominently, thick, hardy, cottonwoods line the banks of the Bighorn River.
