Ground Cover - Grasses

AUS-ASC-FOR-GCG General Moderate confidence

Benchmark Value

1 %
Direction: Higher is desirable ↑
Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

The benchmark cover for Medium Non-tufted Graminoid in EVC 43 is 1%.

Metric Definition:

Percent cover of ground layer grasses and graminoids

Benchmark Definition:

This benchmark represents the typical percent cover of medium non-tufted graminoid grasses in the ground layer of sub-alpine forest ecosystems under pristine conditions.

Justification:

Reflects the 'snow-grass' swards that define the alpine landscape and their ecological importance.
