Evidence & Context

The reference value of 10-20% bare ground is selected as the benchmark representing the best available condition for Temperate Dry Woodlands and Native Grasslands managed as Conservation / Protected Natural Areas in Australia.

Metric Definition:

Percentage of exposed soil surface not covered by live vegetation, plant litter, or rock

Benchmark Definition:

Bare ground, quantified as the percentage of exposed soil surface not covered by live vegetation, plant litter, or rock, serves as a fundamental indicator in the assessment of ecosystem health in Temperate Dry Woodlands and Native Grasslands under conservation management.

Justification:

This benchmark is derived from ecological condition benchmarks used by the ACT Government for monitoring high-quality White Box-Yellow Box-Blakely’s Red Gum Grassy Woodland (BGW) and Natural Temperate Grassland (NTG) in environmental offset and conservation areas.

Notes

The 10-20% bare ground range is considered optimal because it signifies minimal detrimental bare ground (thus low erosion risk and high habitat quality for many species) while accommodating the small-scale, naturally occurring bare patches that contribute to structural diversity and provide microhabitats.
