  1. Summary and Comparison of Version 3.0 and Version 4.0

  2. “The Land Health Concept and Conservation” (1946) “The capacity for self-renewal in the biota.” • Abnormal erosion • Decline of yields • Shortening of species lists • Dominance of plant weeds Symptons of “Land Sickness”

  3. Indicators Attributes Interpretations Applications

  4. Quantitative & Qualitative Studies • Quantitative • Objective • Measure attributes “Cheatgrass cover is 85%” • Qualitative • Observed • Describe or rate attributes • “Cheatgrass is rated as abundant” Strength in Combining the Two

  5. What’s Next? Monitoring Manual for Grassland, Shrubland and Savanna Ecosystems • Version 4.0- peer review completed • Published this summer • Protocol will continue to evolve • Quantitative Manual (Spring/03)

  6. BLM’s National Training Center (Phoenix) • Course 1730-37 is an interagency course for BLM, NRCS, & NPS (others welcome) • Measurements added • Next course-Boise, ID – June 23-27, 2003 Contact -Julie Decker 602-906-5507 /Measuring

  7. Changes from Version 3.0 to 4.0 Ecological Site Description and/or Ecological Reference Area(s) replaced by Reference Worksheet

  8. Changes from Version 3.0 to 4.0 • Discarded Species Abundance Worksheet and incorporated this information into the Functional/Structural Worksheet • Incorporating more spatial context and State and Transition models into the protocol. • Fine-tuned the worksheets to improve usability.

  9. Quantitative

  10. Interpreting Indicators of Rangeland HealthIntended Uses • Used by experienced personnel • Provide a preliminary evaluation of rangeland health • Identify areas (early warning) that are potentially at risk of crossing a threshold • Communication tool

  11. Interpreting Indicators of Rangeland HealthNotto be used to: • Identify the cause(s) of resource problems • Make grazing or other management decisions • Stand alone as a trend or monitoring tool • Independently generate national/regional assessments of rangeland health

  12. “This technique is not to be used as a monitoring tool (e.g., trend) nor is it to be used as the sole basis for grazing decisions.” • Additional qualitative and quantitative information should be evaluated for BLM S&G’s • Review “Intended Uses” section of TR to insure that this protocol is not used inappropriately

  13. Let’s work together to make it better
