Evidence & Context
The mean value of 2.6 m²/ha for the grazed control plots in arid A. aneura woodlands is the most robust and relevant figure.
Basal area, the cross-sectional area of tree stems at a standardized height (typically breast height), provides a robust measure of stand density and the size of mature trees.
This benchmark represents the typical basal area in grazed arid A. aneura woodlands within the Arid Mountain Ranges & Uplands biome, reflecting a stable and functional condition under livestock grazing.
This value is selected as it represents the 'best-on-offer' real-world condition for a functional, sustainably managed grazing landscape, rather than an ungrazed wilderness state.
