In Oregon and Washington, the BLM administers approximately 14 million acres of rangelands.
These arid and semiarid lands stretch from the salt and alkali deserts of the Humboldt River drainage in extreme southern Oregon to the glaciated highlands of the Okanogan in northern Washington. The diverse climates, terrains, soils, and plants of the region call for an approach to land management that is respectful of the characteristics of individual sites and incorporates those characteristics into management decisions.
In managing rangeland ecosystems, the BLM conducts monitoring and rangeland health assessments to assess watershed function, ecological processes, water quality and habitats for native and threatened and endangered species.
Management of these lands is focused on restoring rangeland health where necessary and maintaining healthy landscapes where they currently exist.
