Evidence & Context

Based on the analysis of these six reference sites, the derived benchmark for Litter Cover (%) in Arid Karstic Woodlands & Shrublands under conservation management is a range of 22.5% to 44.1%.

Metric Definition:

Litter cover is defined as the proportion of the ground surface covered by natural, non-living organic matter, including fallen leaves, twigs, bark, and other plant detritus.

Benchmark Definition:

This benchmark represents the optimal range of litter cover percentage in Arid Karstic Woodlands & Shrublands under conservation management, indicating healthy soil stability, moisture retention, and habitat quality.

Justification:

Derived from empirical data from six high-quality TERN AusPlots reference sites representing best available natural condition in conservation areas.
