This document serves as a comprehensive guide for the Bureau of Land Management (BLM) regarding the inventory procedures for assessing wilderness characteristics, particularly focusing on naturalness. It outlines the background, key components of route analysis, and boundary identification. Furthermore, it discusses how to evaluate the naturalness criteria, including the assessment of noticeable human developments and cumulative impacts. Proper documentation and rationale for naturalness findings are emphasized, providing a clear protocol for maintaining ecological integrity and wilderness quality.

  2. Wilderness CharacteristicsGuidance for the BLM Inventory Procedures: Naturalness Inventory - Naturalness

  3. Naturalness – part 1 • Appears to be in a natural ecological condition • to the average visitor, not trained biologist • not ”pristine” or total ecological integrity • relatively unaffected by modern human activities • non-native species do not automatically disqualify Inventory - Naturalness

  4. Naturalness – part 2 • Are human developments too noticeable? • area should look at though it was affected primarily by the forces of nature • human developments substantially unnoticeable • document all noticeable human impacts Inventory - Naturalness

  5. Naturalness – part 2 • Are human developments too noticeable? trails & trail signs fire rings small radio repeaters stockponds cultural properties weather stations fences spring developments • Cumulative impacts? Inventory - Naturalness

  6. Naturalness – part 2 • Cumulative impacts? Inventory - Naturalness

  7. Naturalness – part 2 • Cumulative impacts? Inventory - Naturalness

  8. Naturalness – part 2 • Do not consider impacts from outside – • unless they ruin ecosystem function • Evaluate major effects from outside Inventory - Naturalness

  9. Naturalness – Documentation • Document naturalness rationale • appears to be in natural condition • looks to be affected primarily by the forces of nature • human impacts substantially unnoticeable Inventory - Naturalness

  10. Naturalness – Documentation • Document naturalness rationale • If naturalness criterion is not met • no wilderness characteristics • further inventory activity not necessary • document! • If naturalness criterion is met • proceed to “opportunities” criterion Inventory - Naturalness
