Evidence & Context
The optimal operating range for balancing ecological health and sustainable production is approximately 38-52 m²/ha.
Basal Area (BA) is a standard forestry metric that quantifies the density of a forest stand.
This benchmark defines the optimal basal area range for balancing ecological health and sustainable production in subtropical rainforest forestry.
This range reflects the dynamic cycle of a managed forest, from a healthy post-harvest state (~38 m²/ha) to a mature, recovered stand (~52 m²/ha) ready for the next harvest cycle.
