Exotic and Invasive Species
The Malheur National Forest is using an integrated approach to manage invasive plants, which includes prevention; manual, mechanical, herbicide, biological control and cultural treatments; and restoration work. This work to prevent the expansion of infestations will be implemented under the 2015 decision for the Malheur Site-Specific Invasive Plants Treatment Project and the Forest Plan amended by the Pacific Northwest Region 2005 decision for Preventing and Managing Invasive Plants.

Treatment sites are located across the Malheur National Forest and herbicide treatments will be signed at the time of treatment. A blue marker dye that will fade over time will be mixed with herbicides to alert people of where product has been applied.
