Table 3 The basic criteria followed to classify the field observations of rangeland conditions to 5 degradation levels

From: A scalable big data approach for remotely tracking rangeland conditions

Degradation levels

Criteria

Healthy

All native dominants are in place.

Slightly degraded

Key dominants are still dominating, some grazing-sensitive forbs are in decline and grazing-resistant species are in increase.

Moderately degraded

Dominants are in decline and replaced by other subdominants, number of species drops down.

Heavily degraded

Remnants of key species are thinning, and the abundance of degradation indicator species increases.

Fully degraded

Total vegetation cover is reduced or dominated by very few degradation indicator species.
