This project is a joint effort of the Sustainable Rangelands Roundtable and the Society for Range Management. During a series of meetings from 2001 to 2003, the Sustainable Rangelands Roundtable (SRR) developed the five criteria and 64 indicators of sustainable rangeland management. The SRR is a collaborative, inclusive organization, comprised of participants representing universities, federal research agencies, federal, state and local land management agencies, tribal governments, scientific societies, and both environmental and commodity-oriented non-governmental organizations. To achieve its goal, the SRR dealt with multiple issues, including those of scale and definitions. The criteria used are based on those of the Montreal Process and the concept of sustainability used here originates from the internationally-accepted definition for sustainable development contained within the UN's Brundtland Report: “... development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” More specifically, the SRR defines sustainable rangeland management as involving "the kinds of management that consider all aspects of rangelands, including their environmental, economic, and social values and the attempts to integrate them to achieve a sustainable future.
This indicator measures the population levels (abundance) and the current geographic ranges of rangeland-dependent plant and animal species, monitored across their known range. It is not possible to monitor the population levels and ranges of all species of animals, plants, and microorganisms, so some species must be selected for monitoring. If the selected species include keystone species and those that are sensitive to particular threats, such as overgrazing, irreversible soil erosion, or fire, and if the species are diverse with respect to their taxonomy, habitats, trophic levels, ranges, and life strategies, the indicator will have a higher
likelihood of detecting trends in range ecosystems.
