Evidence & Context

The Victorian Government's Ecological Vegetation Class (EVC) benchmarks, which are used to assess habitat quality, define the range for a healthy Grassy Woodland as 10% to 30% TCC.

Metric Definition:

Tree Canopy Cover (TCC) as the percentage of ground covered by tree canopy in Temperate Grassy Woodlands.

Benchmark Definition:

This benchmark represents the natural healthy range of tree canopy cover in Temperate Grassy Woodlands under production forestry, supporting open woodland structure and biodiversity.

Justification:

This range represents the natural, healthy state of the biome as defined by high-quality remnant sites and ecological benchmarks.

Notes

This range is the target for best-practice production forestry to maintain the open woodland structure and support biodiversity. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
