Evidence & Context
Reference Value: 1.5 - 2.5 m²/ha (representing 10% of a farm managed as functional, multi-row shelterbelts with an internal BA of 15-25 m²/ha)
Basal Area (BA) is defined as the sum of the cross-sectional area of all tree stems, measured at breast height, expressed per unit of land area.
This benchmark represents the basal area of tree stems per hectare in temperate dry woodlands and native grasslands under agricultural crop production, reflecting best-practice regenerative cropping systems with functional shelterbelts.
Derived by synthesizing optimal shelterbelt design principles with landscape-scale ecological function, representing a best-practice regenerative cropping system.
