AUS-ASC-CON-LIT General Moderate confidence

Benchmark Value

55 %

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

For Western subalpine scrub (SSW), particularly the Banksia marginata facies, the benchmark for organic litter cover is 55%.

Metric Definition:

Percent cover of organic litter.

Benchmark Definition:

Reference benchmark for undisturbed subalpine scrub in Tasmania.

Justification:

This high value reflects the structural density of the scrub, which is dominated by small trees and large shrubs that contribute substantial woody and foliar litter to the forest floor.
