About the Forest

 

 A Quick Overview

 

 Hiking in the Trinity Lake recreation area.

The Boise National Forest is approximately 2,612,000 acres. Elevations vary greatly, from 2,800 feet in the North Fork Payette River Canyon to nearly 10,000 feet atop Steel Mountain. This wide range of elevations across 2 million acres encompasses a great diversity of geologic features. Geologically the Forest is dominated by granitic rock, with inclusions of basalts to the west, and volcanic rock to the south. 

 

Major mountain ranges include the Boise, Salmon River and West Mountain ranges featuring steep slopes of coarse-textured soils that readily take in and transmit water. Unless these soils are disturbed, surface run-off is rare except during high intensity storms or rain-on-snow events.

The Forest has an estimated 9,600 miles of perennial and intermittent streams, and 15,400 acres of lakes and reservoirs. Major river systems on the Forest are the Salmon, Payette and Boise. There are an estimated 28 species of fish found on the Forest; this includes 11 species that are not native or are introduced into areas they historically did not occur.

The Forest contains large numbers of big game species, such as mule deer and Rocky Mountain elk. The average annual precipitation ranges from 15 inches at lower elevations to 70 inches at higher elevations.

 

  

 

 

Approximately 76 percent of the Forest’s lands are considered forested and about 23 percent are considered non-forested or dominated by grass, forb, shrub, or brush species. Much of the non-forested habitat is found at lower elevations or on the more southern latitudes, southern aspects.

Habitat restoration, both aquatic and terrestrial is an emphasis of our 2010 Forest Plan, influencing the development and implementation of many projects. Recreation, grazing, mining and a diversity of special uses occur on the Forest.
