Projected sage-grouse habitat

Total amount of area (km^₂) in potential spring, summer, and winter habitat classes at three greater sage-grouse (Centrocercus urophasianus) Priority Area for Conservation (PACs) in the Great Basin (Klamath Oregon/California [KLAM], 658 km²; Strawberry Utah [STRAW], 1308 km²; NW-Interior Nevada [NWINV], 1504 km²) under five restoration scenarios of simulated sagebrush-steppe vegetation growth and cover change. Restoration actions shown include passive (no restoration), seeding, low-density (LD) planting, high-density (HD) planting, and multi-year (MY) restoration (LD planting [NWINV], or seeding & HD planting [KLAM, STRAW]). Red dashed line denotes “minimum” required amount of total landscape area (20-km²) in the suitable habitat class for sage-grouse. Habitat was seasonally classified based on sagebrush (Sage) and perennial grass (PG) component cover values. Spring habitat was defined as: suitable (15–25% Sage; ≥10–15% PG), marginally suitable (5–15% or >25% Sage; 5–15% PG), and unsuitable (<5% Sage; <5% PG). Summer habitat was defined as: suitable (10–25% Sage; ≥15% PG), marginally suitable (5–10% or >25% Sage; 5–15% PG), and unsuitable (<5% Sage; <5% PG). Winter habitat was defined as: suitable (≥10% Sage), marginally suitable (5–10% Sage), and unsuitable (<5% Sage).
