  1. Indicators for Soil and Water Conservation on Rangelands Sustainable Rangelands Roundtable

  2. W.C. Lowdermilk. 1953. Conquest of the land through 7,000 years. Natural Resources Conservation Service Soil erosion is regarded as a major contributor to declines in human civilizations over the past 7,000 years.

  3. Working Members of Soil and Water Group (Feb. 2002)

  4. 14 Indicators of Soil and Water Resources 7 soil-based 6 water-based 1 soil & water-based Retained 7 soil & water resources indicators from Roundtable on Sustainable Forests

  5. 7 Soil-Based Indicators

  6. 6 Water-Based Indicators

  7. Soil and Water-Based Indicator Area and Percent of Rangeland Managed Primarily for Protective Functions

  8. Challenges and Opportunities (So Far) Applicability of Indicators over Broad Geographic Areas Some indicators, like soil compaction, appear only over very small portions of rangelands; therefore aren’t widespread problem.

  9. Conclusions and Future Work 1. Creation of Sustainable Water Resources Roundtable; potential overlap could result in reduction of number of water-based indicators 2. Some overlap in indicator identification between Soil & Water Group, & Ecological Health & Diversity Group (e.g. diversity of soil organisms indicator) 3. Integration between Roundtables and within groups within Rangelands Roundtable will minimize overlap

  10. Conclusions and Future Work 4. More than one indicator appears to be indexing same rangeland component E.g. soil erosion, soil aggregate stability, organic matter content, & soil compaction, are 4 indicators that all relate to soil erosion Are fewer adequate?
