BLM OR Greater Sage Grouse General and Priority Habitat Management Area Polygon Hub

The purpose of this dataset is to record polygon features identified as Greater Sage-Grouse Priority and General Habitat Management Areas in Eastern Oregon for use in the Greater Sage-grouse RMP Amendments ROD, signed January 16, 2025. The dataset Greater Sage-Grouse General and Priority Habitat Management Areas (GRSG_HMA) has been historically referred to as GHMA/PHMA.
"Priority Habitat Management Areas (PHMA) have the highest value to maintaining sustainable GRSG populations and can include breeding, late brood-rearing, winter concentration areas, and migration or connectivity corridors. The BLM intent for these areas is to maintain and enhance habitat conditions that will support persistent and healthy GRSG populations through management to minimize habitat loss and degradation. General Habitat Management Areas (GHMA) are lands that are, or have the potential to become, occupied seasonal or year-round habitat outside of PHMA, managed to sustain GRSG populations. These areas are defined differentially by state wildlife management agencies but generally are of poorer GRSG habitat quality with reduced occupancy when compared to PHMA. Some state wildlife agencies have identified areas of GHMA as important for restoration, connectivity, or seasonal habitats. The intent for GHMA is to maintain habitat conditions to support GRSG populations consistent with the state agency designations of recovery, connectivity, or seasonal habitats.

The Oregon Department of Fish and Wildlife sage-grouse core and low-density habitat map was originally delineated in 2011 as one component of the Oregon Sage-Grouse Conservation Assessment and Strategy (CAAS). The core and low-density habitat map was updated in 2023 with the Department's most recent sage-grouse data and the best available science, following the methodology outlined in the CAAS. As part of the update process, the draft map was reviewed by ODFW District Biologists, cooperating agency biologists, conservation partners, and the public to ground-truth and refine the boundaries at a 1:10,000 scale. The final map was adopted by the Oregon Fish and Wildlife Commission on 15 December 2023. Updated sage-grouse Priority Area for Conservation (PAC) boundaries were delineated within the final approved core habitat and appropriately named. ODFW sage-grouse core habitat and sage-grouse PACs are analogous.
The BLM Oregon PHMA and GHMA HMAs were identified using ODFW core and low-density sage-grouse habitat designations from December 2023. PHMA boundaries are equal to ODFW’s core habitat. GHMA boundaries equate to ODFWs low density habitat plus Habitat Assessment Framework (HAF) mapped seasonal habitat.
