Condition Score
47/100
Stocking Adjustment
-30%
How to Use This Calculator
- Enter Desirable Species, Increaser Species, and Invasive/Undesirable Species.
- Set Bare Ground, Erosion Evidence, and 1 - None visible.
- Adjust 2 - Slight, 3 - Moderate as needed.
- Review Condition Score (/100) and Stocking Adjustment (%).
- Use Condition Class and Trend to inform your decision.
How the result changes with Desirable Species
| Desirable Species | Condition Score | Stocking Adjustment |
|---|---|---|
| 10 | 27/100 | -30% |
| 35 | 37/100 | -30% |
| 65 | 49/100 | -30% |
| 90 | 59/100 | -10% |
What each input means
- Desirable Species
- Percentage of desirable, climax-type forage species.
- Increaser Species
- Percentage of species that increase with moderate grazing.
- Invasive/Undesirable Species
- Percentage of invasive weeds and undesirable species.
- Bare Ground
- Percentage of bare ground visible (higher = worse condition).
- Erosion Evidence
- Visual erosion assessment of the rangeland.
What each result means
- Condition Score
- Overall range condition rating.
- Condition Class
- 1=Excellent, 2=Good, 3=Fair, 4=Poor.
- Stocking Adjustment
- Recommended reduction from full stocking rate.
- Trend
- 1=Improving, 2=Stable, 3=Declining.
- Management Action
- 1=Maintain, 2=Improve, 3=Rest, 4=Reseed.
