Popis: D esigning restoration strategies based on succes- sional management requires an initial assessment of the functional status of ecological attributes across a management unit. Seriously damaged rangelands may not have the capacity for self-repair and often experience continued degradation. 1 Over the past 20 years, there has been a concentrated effort to develop a practical and effective protocol for assessing the status of rangeland health and managing vegetation change in heavily degrad- ed rangelands. In the mid-1990s, a US National Research Council panel and a Society for Range Management task group advocated the use of early warning indicators to assess soil stability, water cycle, energy ow, nutrient cycling, and the resilience and resistance of plant communities to change following disturbances. Currently a widely adopted range- land health assessment tool in the United States is “Inter- preting Indicators of Rangeland Health, version 4,” described by Pyke et al. 2 and Pellant et al. 3 This qualitative rangeland health assessment protocol provides early warnings of altered ecological processes and can help identify potential candidate locations for establishing quantitative monitoring plots for long-term trend studies.
