Wildlife Associated with Scoria Outcrops: Implications for Reclamation of Surface-Mined Lands

摘要

Bird and mammal populations using scoria rock outcrop and adjacent sagebrush/grassland habitats were studied. Bird populations and bird species richness were greater in the outcrop habitats than in the surrounding sagebrush/grassland habitats. These differences were attributed to the structural features provided by the outcrops. Most, but not all, small mammal populations also were larger in outcrop habitats. Reclaiming surface-mined lands with rock outcrops would enhance wildlife habitat, especially for birds.
