| Low (1–1.24) |
Invader species are<5% of vegetation cover and annual plants >25%, Surface litter is >90%, Foliage cover of perennials is >85% |
cutting of brush and uproot of the shrub is not seen, Stocking rate is equal to the rang capacity |
Reproduction of plants are done naturally, The region does need not to reclamation projects, Decreases and increaser species are 70 and 30% respectively, and invaders ones are not seen |
| Medium (1.25–1.49) |
Invader species are5-20% of vegetation cover annual plants 25–50%, Surface litter is70-90%, Foliage cover of perennials is 15–30% |
trees are more than annual biomass, Stocking rate is a little more than annual production |
Reproduction of plants are access able with low expense, Range improvement projects are successfull and effective, Decreases and increaser species are dominant, and invaders ones are seen seldom |
| High (1.5–1.74) |
Invader species are20-50% of vegetation cover and annual plants are dominant, Surface litter is 30–70%, Foliage cover of perennials is 5–15% |
cutting of brush, bush, and trees are apparent, Grazing is more than capacity |
Regeneration of plants involve high expense, Range improvement plans are a success to some extent, Invaders and increaser species are dominant and decrease ones are not seen |
| Very High (1.75–2) |
Invader species are>50% of vegetation cover, and annual plants are dominant, Surface litter is <30% foliage cover of perennials is <5% |
Heavy cutting of brush, bush, and trees, Heavy stocking rate |
Regeneration of plants are impossible (ecological problem), Range improvement projects have not successes till now, Invaders species are dominant, and increaser ones are not seen |
