Idaho Forestry Best Management Practices (BMPs)
Water. Cool, clean, plentiful water. Idaho’s 93,000 miles of rivers and streams support many uses.
In Idaho, as in all of the western United States, water rights, water quantity and water quality are at the center of many of our environmental challenges.
Forestry best management practices (BMPs) are those found to be the most effective means of preventing or reducing non-source pollution delivered to streams and rivers by forest practices. BMPs also protect water quality by providing
- shade, which keeps streams cool;
- vegetation, which captures sediment before it can enter streams; and
- large woody debris, which increases aquatic habitat.
This field guide was developed by University of Idaho Extension to educate forest landowners, managers and operators about Idaho Forest Practices Act (IFPA) rules that protect, maintain and enhance Idaho's forests and maintain high water quality.

Class I Streamside Tree Retention Rule
A revised Class I Tree Retention Rule (“Shade Rule”) was approved by the Idaho Legislature in 2022. The rule changes aim to simplify the existing “Shade Rule” and refine the definition of Class I streams.
