Evidence & Context
A Basal Area below approximately 2.0 m²/ha is unlikely to represent a sufficiently dense or extensive tree network to provide the intended landscape-scale functions.
Basal Area (BA) is the sum of the cross-sectional area of tree stems at breast height per hectare.
This benchmark defines the minimum basal area required to maintain functional ecological services in agroforestry systems within the biome.
Based on planting density and mature tree size assumptions, supported by agroforestry design guidelines.
