Gully Density
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 9 benchmarks together — the OptimalRange form drives the primary score, while 8 guard(s) constrain the result.
Evidence & Context
Reference Value: The ideal reference value for active gully density is 0 m/ha. This reflects the "no erosion" standard of 'A' condition land.
Active gully density measured as length of active gully erosion per hectare of land area.
Active gully density is the length of active, accelerated gully erosion per hectare of land area, with zero representing the ideal no-erosion condition in tropical and subtropical rainforest grazing lands.
The benchmark is supported by the qualitative definition of 'A' condition land requiring no erosion, large-scale mapping showing very low to no gully presence, and studies showing cessation of erosion under grazing exclusion.
