Bitterroot National Forest

Forest Overview

Spanning 1.6 million acres between two mountain ranges in west central Montana and east central Idaho, the Bitterroot National Forest boasts the largest expanse – 743,000 acres – of continuous pristine wilderness in the lower 48 states.

Mountainous terrain and deep, glaciated canyons are graced with stands of Douglasfir, lodgepole pine and western larch, with Englemann spruce, subalpine fir, subalpine larch and whitebark pine at higher elevations. Deer, mountain lions, moose, and black bear are among the many species that make the Bitterroot their home.

What We Are Doing

Summer 2000 was an unforgettable year of forest fires in Montana and the Bitterroot Valley. Devastating firestorms burned more than 370,000 acres – over 23% – of the Bitterroot National Forest, destroying millions of trees. More fires in following years increased the already critical need for replanting.

So far, we have planted 51,660 ponderosa pine, Douglasfir, lodgepole pine, and Englemann spruce to help restore the forest while stabilizing soil, protecting critical watersheds and wildlife habitat, reducing the spread of weeds, and re-establishing magnificent, large pine stands in the Bitterroot Valley.

You can help repair damage to wildlife habitats. Read about our efforts in each and restore the awe-inspiring beauty of our state and national forests.
