Wild Plants and Animals

The Boise River begins with snow and rainfall on the highest peaks of the Sawtooth Mountain Range and ends on the Snake River plain where it enters the Snake River. The Boise River watershed encompasses 4,100 square miles; the mainstem river is 104 miles long. During its journey, the Boise River flows through an incredibly diverse array of landscapes all of which are home to birds, fish, animals, plants, reptiles, amphibians and many other living things.

The cold, clean water of the upper Boise River is the habitat of  many native species of fish, including the endangered bull trout. The lower reaches of the Boise River support cold- and warm-water fish species. Deer and elk and other game species live in the mountains and foothills and visit the river for water and shelter. Beavers, mink and river otters live along the Boise River, and dozens of species of birds live all or part of their lives near the river. The galleries of native cottonwood trees that gracing the banks of the lower Boise River, with their native understory of willow, are popular bird and animal real estate.

The Boise River’s rich ecosystem includes the river channel, the riparian area along the banks, wetlands and sloughs, and upland habitat. With the advent of irrigation, the Boise River also began supporting farm fields, backyards and parks, and many other kinds of urban and rural landscapes and the plants and animals that live there.

We love the Wild Boise River

The presence of bugs, birds, fish, wildlife, trees and the rest of the wild things of the Boise River enriches our lives immensely. Many people love to hunt, fish and forage; others love to  search out places to view birds and wildlife, and many of us simply enjoy bird songs and shady trees as we go about our lives.

Protecting the Boise River protects the

wild creatures and places we all love.
