Direction: Lower is desirable ↓

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

This system categorized areas based on the percentage of weed cover, ranging from "Scattered" (less than 20% cover)

Metric Definition:

percentage of weed cover

Benchmark Definition:

In the Alpine and Subalpine Complex conservation areas, a weed cover less than 20% is categorized as 'Scattered', representing a conservation target condition for invasive species presence.

Justification:

Part of a six-class density system used to map weed infestations at Perisher.
