Changes from Version 3.0 to 4.0 – page iii
1) Added the Reference Sheet
2) Evaluation matrices are ecologically site-specific
3) Litter movement indicator moved from Hydrologic Function to Soil and Site Stability Attribute
4) Added Quantitative and Qualitative linkages
5) Revised worksheets to improve usability

Improved Worksheet Usability
• Eliminated ‘Species Dominance’ and ‘Cover’ Worksheet’s
• Added noxious weeds and invasive plants to Functional and Structural Groups Sheet
• Evaluation Sheet •Emphasizes written justifications•The “Extreme Departure” rating was
changed to “Extreme to Total Departure”

Terminology
• Inventory
• Monitoring
• Assessment
What's the
difference?
12
Inventory The systematic acquisition and analysis of
resource information needed for planning and management. This information is generally not collected as frequently as monitoring data.
13
Monitoring
The orderly and quantitative collection, analysis and interpretation of resource data to evaluate progress toward meeting management objectives.

Assessment The process of estimating or judging the
value or functional status of ecological processes (e.g., rangeland health). It is generally a “moment-in-time” evaluation that is not repeated in the future (not a monitoring tool).

Applying the Five Steps – pg 17
1. Verify soils2. Obtain or develop Reference Sheet3. Collect supplementary information4. Rate the 17 indicators5. Evaluate the 3 rangeland health
attributes

STEP 1
Verify soils to identify
the Ecological Site at the evaluation
area
18
Step 1 – Verify Soils to Identify Ecological Site at
Evaluation Area• Consider slope, aspect, elevation, &
topographic position
• Verify soil with a shallow soil pit:• Surface Texture• Depth to restrictions• Diagnostic horizons
• Identify ecological site
• Document soil-ecological site information on Evaluation Sheet- Appendix 1 (page 66)
