Bare Ground
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 2 benchmarks together — the Point form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context
Based on this analysis, the median Bare Ground percentage is 35.1%, with an interquartile range of 30.2% to 40.5%. This range (rounded to 30-40%) is proposed as the reference value, as it captures the typical variability of the system in a healthy state.
Bare Ground (%) as the percentage of ground surface not covered by vegetation or other ground cover, derived from satellite fractional cover data.
Percentage of bare ground as derived from satellite fractional cover data representing the natural state of the ecosystem in the Arid Karstic Woodlands & Shrublands under conservation management.
The reference value represents the interquartile range (25th-75th percentile) of long-term median bare ground percentage derived from satellite data (RAPP Map) for the Nullarbor National Park, Regional Reserve, and Wilderness Protection Area, validated by ground-based surveys indicating over 90% of the region is in good to very good condition.
