South Clearwater Forested Mountains

Ecoregion in Rocky Mountains in ID, MT

Generate High-Quality PDF

The South Clearwater Forested Mountains ecoregion receives more maritime influence than ecoregions to the south but less than those to the north. Grand fir is usually the sole maritime tree species in the elevational zone between Douglas-fir and subalpine fir. Logging has caused slope instability (especially in granitic areas) and stream sedimentation. Placer gold mining has also heavily affected rivers.
