Evidence & Context

Based on the synthesis of geomorphological principles and the preventative "zero-by-design" paradigm embedded in Australian forestry regulations, the reference value for active Gully Density in a production forestry system operating under best practice is 0 m/ha.

Metric Definition:

Gully Density is a measure of landscape stability, quantified as the total length of active gullies per unit area, typically expressed in metres per hectare (m/ha).

Benchmark Definition:

This benchmark represents the target of zero active gully erosion in production forestry systems in temperate grassy woodlands and plains, reflecting best practice landscape stability management.

Justification:

The benchmark represents the successful implementation of preventative measures mandated by State Codes of Practice and technical BMPs, aiming for zero active gully erosion.

Notes

Active gullies are defined by evidence of recent or ongoing erosion; legacy gullies that are stabilized and vegetated are not counted against the benchmark.
