Boise and Sawtooth Invasive Plant Species Project
Boise and Sawtooth National Forests
– Project Description
The purpose of this project was to reduce the negative effects of existing and future invasive plants on the structure and function of native plant communities and other natural resource values. Vast areas on both Forests were threatened by the introduction and establishment of weed species, particularly in areas as high risk because of recent wildfire.
The project area included all National Forest System lands within the 2,267,000 acres of the Boise National Forest and 2,170,000 acres of the Sawtooth National Forest.
The proposed action prioritized weed species and treatment areas on both Forests; identified and treated existing priority weed infestations using a variety of methods; improved sagebrush obligate habitat by managing invasive weed species through preventions, removal, or containment; limited the spread and effect of nonnative invasive species in sage-steppe ecosystems; and prevented or limited the introduction and establishment of identified weed species, particularly in areas as high risk because of recent wildfire.

Climate Change and Invasive Species
Climate change is having an important influence on invasive species. The increase in temperatures, rainfall, humidity, and drought can facilitate their spread and establishment, creating new opportunities for them to become invasive.
To manage invasive species under a changing and unpredictible climate, invasive species must be contained. Land managers will also need to anticipate which species will spread to new habitats and understand how the characteristics of specific invaders may disrupt invaded ecosystems.
