This Instruction Memorandum (IM) provides guidance on prioritizing implementation decisions for Bureau of Land Management (BLM) oil and gas leasing and development, to be consistent with the Approved Resource Management Plan Amendments for the Rocky Mountain and Great Basin GRSG Regions and nine Approved Resource Management Plans in the Rocky...
Coastal upwelling regimes are some of the most productive ecosystems in the ocean but are also among the most vulnerable to ocean acidification (OA) due to naturally high background concentrations of CO₂. Yet our ability to predict how these ecosystems will respond to additional CO₂ resulting from anthropogenic emissions is...
During the 2016 greater sage-grouse breeding season, 1,908 aerial and ground lek surveys were conducted at 768 individual lek sites comprising 501 lek complexes. Surveys were conducted at 66.0% of known lek sites in the state, which was the greatest proportion of leks ever surveyed in Oregon. Survey effort during...
Grass carp Ctenopharyngodon idella are sometimes used as a biological tool for managing aquatic vegetation in reservoirs. Sterile, triploid fish were stocked in Devils Lake, Oregon, during 1986, 1987, and 1993 to control aquatic vegetation. We present a case study for using multiple measures on the same fish to determine...
This Instruction Memorandum (Instruction Memorandum No. 2016-139) provides guidance on the use of terrestrial and aquatic objectives and quantitative data to determine Resource Management Plan effectiveness. Additionally, for RMPs that include Greater Sage-Grouse (GRSG) habitat, this IM provides guidance for tracking and reporting on the implementation of decisions using the...
This Instruction Memorandum (IM) directs the implementation of the land use plan adaptive management process to evaluate and apply hard and soft triggers and responses, as detailed in the Greater Sage-Grouse (GRSG) Approved Resource Management Plans and Amendments (GRSG Plans), Great Basin and Rocky Mountain GRSG Regional Records of Decision...
This Instruction Memorandum (IM) provides guidance for prioritizing the review and processing of grazing permits and leases (permits) in Greater Sage-Grouse (GRSG) habitat as described in the Records of Decision for the Approved Resource Management Plan Amendments or the Great Basin and Rocky Mountain GRSG Regions and nine Approved Resource...
This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative invasive annual grasses and...
