The forests of the area are diverse, reflecting the variety of topography and climate. The west side of the area, along the Fraser River, has a hot dry climate resulting in grasslands and interior Douglas-fir ecosystems. Conversely, the Cariboo Mountains on the east side of the area have a wetter climate, steeper slopes, and forests that consist of interior spruce, balsam fir, cedar, hemlock, sub-alpine fir, lodgepole pine and Douglas-fir. The central portion of the area is a relatively high elevation, dry, flat interior plateau with lodgepole pine, Douglas-fir and interior spruce forests. (TSAR page 3)
