This standard focuses on retaining and restoring native plant and animal species (includ- ing fish), populations, and communities (including threatened, endangered, and other special status species and species of local importance). To meet the standard, native plant communities and animal habitats would be spatially distributed across the landscape with a density and frequency of species suitable to ensure reproductive capa- bility and sustainability. Plant populations and communities would exhibit a range of age classes necessary to sustain recruitment and mortality fluctuations. Potential indicators to measure the achievement of Standard 5 include: • Plant community composition, age class distribution, and productivity • Animal community composition and productivity • Habitat elements • Spatial distribution of habitat • Habitat connectivity • Population stability and resilience Louse Canyon GMA Findings The pasture-level objectives were used as the basis for evaluating the achievement of Oregon's Rangeland Health Standard 5 for terrestrial uplands in pastures within the Louse Canyon GMA. The Louse Canyon GMA is approximately 523,000 acres and contains 4 allotments, the Campbell, Anderson, Star Valley Community, and Louse Canyon Community allotments. There are 20 pastures within these 4 allotments, the majority of which are composed of shrub-steppe vegetation types, primarily big sagebrush vegeta- tion types. Table 5 summarizes the determinations made for each pasture regarding achievement of Oregon's Rangeland Health Standard 5 on terrestrial uplands. Fifteen of the 20 pastures did achieve the sage- brush canopy cover structural conditions and herbaceous
