Scoring Curve

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

Evidence & Context

A transition to a dysfunctional, severely degraded state occurs when invasive plant cover exceeds 50%.

Metric Definition:

Percentage cover of invasive plant species indicating severe ecosystem degradation.

Benchmark Definition:

This benchmark defines the upper threshold of invasive species cover indicating severe ecosystem degradation with active erosion and very low productivity.

Justification:

Defined by State and Transition Models as the upper detrimental threshold marking a dysfunctional state.

Notes

Above this threshold, the ecosystem is dominated by invasive species with active erosion and very low productivity. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
