Evidence & Context

Wet Forest (EVC 30) has a canopy cover benchmark of 40%.

Metric Definition:

Canopy cover percentage representing the proportion of land area covered by tree canopy.

Benchmark Definition:

This benchmark represents the structural condition benchmark for natural wet forest systems in Victoria with 40% canopy cover.

Justification:

Large tree DBH threshold is 90 cm; stem density is 20 large trees per hectare.
