Rangeland Health Assessments, Evaluations and Determinations

The results of the Livestock Impacts Studies were used to 1) make an overall assessment of the monumentís livestock allotments and evaluate whether or not the allotments are meeting the Oregon Standards and Guidelines for Rangeland Health290 KB (PDF) (Rangeland Health Assessments (RHAs) and RHA determinations) and 2) determine whether or not current livestock grazing is compatible with "protecting the objects of biological interest" as required by the monument proclamation. In July 2008, the BLM released the RHAs, RHA determinations, and the determination of current livestock grazing compatibility with protecting objects of biological interest. These documents are available electronically:

Summary of Findings

Rangeland Health Assessment Determinations

For allotments administered by the Medford District, one allotment (Soda Mountain) is not meeting all five standards as a result of livestock grazing and two allotments (Deadwood and Keene Creek) are not meeting four out of the five standards. Another allotment (Jenny Creek) is meeting two standards and not meeting the other three standards, but making significant progress. One allotment (Box R) is meeting three standards, and not meeting two standards, but current livestock grazing is not a significant factor.

The RHA determinations for the portions of two allotments administered by the Klamath Falls Resource Area were completed in 2000 and 2001. One allotment (Dixie) was not meeting all five standards as a result of livestock grazing and did not conform with guidelines for livestock grazing management, and one allotment (Buck Mountain) was meeting one standard and not meeting four standards due to causes other than livestock grazing activities. Management changes have since been implemented on the Dixie Allotment.

Determination of Current Livestock Grazing Compatibility with Protecting Objects of Biological Interest:

There are locations within the CSNM where current livestock grazing practices are not compatible with protecting the objects of biological interest. A final compatibility determination will be made for all of the alternatives evaluated in the National Environmental Policy Act (NEPA) process and the selected alternative will be compatible with protecting the objects of biological interest.
