2. Previous national assessments used range condition as the sole measure of rangeland health or sustainability. In the 48 states, “only 46 percent of the rangelands are in fair or good condition.” Note: Other categories are poor and very poor.

3. Range condition: BLM lands Excellent 4% Good 30% Fair 41% Poor 18% Forest Service lands PNC 15% Late seral 31% Mid-seral 38% Early seral 15% Non-federal lands Excellent 4% Good 31% Fair 47% Poor 17%

4. 2000 Assessment On NFS lands: ~~~~~~~~~~~~~~~~~~~~~~ Meeting FPMO 48% Moving towards FPMO 39% Neither meeting nor Moving towards FPMO 13%

5. HIERARCHY THEORY Hierarchies are ordered systems of constraint. Any level in a hierarchy must communicate with lower levels in order to constrain it. Levels of ecosystems: Pedon, site, landscape, watershed, physiographic region, biome, nation, biosphere. Attributes: Scale -- grain and extent Grain – Threshold for smallest attribute captured. Extent – Upper threshold of an observation protocol. A tradeoff exists between grain and scale.

6. FREQUENCY OF BEHAVIOR • - Systems have particular characteristic frequencies. • - Monitoring must accommodate frequency of a system’s scale. The larger the system, the longer the cycle time of unperturbed behavior. From top to bottom of a hierarchy, there is a continuum of natural frequencies.

7. 1991 Ecological Society of America Sustainable Biosphere Initiative • Focuses on role of ecology in wise management of Earth’s resources. • Calls for increases in fundamental research in three areas: • -Global change • Biological diversity • Sustainability of ecological systems • At broadest scale: Effects of land use patterns • Feedbacks between ecosystem & atmospheric processes

8. FORUM SCIENCE AND SUSTAINABILITY Ecological Applications Vol. 3 No. 4 Pages 545-589 1993 -Based upon paper in Science on resource exploitation. Ludwig et al. 260:17, 36. 1993. -Sustainability is a vague and elusive notion. -Ultimate goal: “Leave to the future the option or capacity to be as well off as we are.” -“Sustainability requires attention to the linkages among physical, biological, and socioeconomic systems, and to the interface between science and policy.”

9. HIGH-PRIORITY RESEARCH FOR HEALTHY ECOSYSTEMS AND PEOPLE 1993 Symposium – Research Affairs Committee, SRM • RESEARCH GOALS FOR • 21st CENTURY • - Provide water for multiple uses. • - Develop environmentally-compatible, • efficient livestock management systems. • - Maintain and enhance riparian systems. • - Develop vegetation management schemes • that ensure ecosystem integrity • - Provide wildlife habitat for a wide array • of native species. • - Understand the needs and direction of • society in relation to rangelands.

10. Evaluating Rangeland Sustainability SRM Task Group on Unity and Concepts in Terms Rangelands 17(3):85-92 1995 • Focused on the site level; i.e. rangeland condition and trend. • Soil is the basic resource. • Sought unity in terminology and methodology. Ecological sites Site conservation thresholds Site Conservation rating: sustainable and unsustainable Desired plant community

11. FORUM ECONOMIC GROWTH AND ENVIRONMENTAL QUALITY Ecological Applications Vol. 6 No. 1 Pages 1-32 1996 Based upon a paper in Science on economic growth and environment. Arrow et al. 268:520-521. 1995. -Relationship between economic growth and environmental quality? -Ecosystems limited in capacity to absorb disturbance. Signals may not allow anticipation of irreversible changes. -Basic ecosystem services are not substitutable: Clean air, pure water, decompose wastes, recovering from disturbance, CO2 balance. -Indices must be intuitively obvious and fit needs of decision-makers.

13. SOME COMMON DENOMINATORS • The concept of sustainability is not concise, but is important. There is agreement that it involves physical, biological, and socio-economic-political systems.

14. SOME COMMON DENOMINATORS • The concept of sustainability is not concise, but is important. There is agreement that it involves physical, biological, and socio-economic-political systems. • No “Dow Jones” of sustainable development or sustainability exists. Quantitative ecological and economic models are not adequate to address any measure of overall sustainability.

15. SOME COMMON DENOMINATORS • The concept of sustainability is not concise, but is important. There is agreement that it involves physical, biological, and socio-economic-political systems. • No “Dow Jones” of sustainable development or sustainability exists. Quantitative ecological and economic models are not adequate to address any measure of overall sustainability. • Sustainability indicators are hierarchical because the systems they monitor are subject to the principles of hierarchy theory.
