Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

For ecosystem-transforming weeds like Buffel Grass, dominance (>30% cover) alters fire regimes and ecosystem function.

Metric Definition:

Foliage cover percentage of Buffel Grass indicating ecosystem dominance and detrimental impact.

Benchmark Definition:

This benchmark defines the maximum acceptable cover of Buffel Grass, above which ecosystem function and fire regimes are detrimentally altered.

Justification:

Cover above this level leads to altered fire regimes and loss of native vegetation.

Notes

Management should aim to maintain cover as close to zero as possible. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
