Form: MaximumOnly

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 significantly compromised ecological state occurs when invasive plant cover exceeds 15%.

Metric Definition:

Percentage cover of invasive plant species indicating ecological compromise.

Benchmark Definition:

This benchmark marks the minimum threshold of invasive species cover beyond which the ecosystem is significantly compromised, leading to loss of native species and increased erosion risk.

Justification:

Defined by State and Transition Models as the lower critical threshold where ecological health is significantly compromised.

Notes

Crossing this threshold leads to loss of key native species, increased bare ground, and high erosion risk. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
