Evidence & Context
The analysis indicates a mean Basal Area within these high-health reference sites of approximately 4.5 m²/ha. To account for natural variability across different soil types and rainfall gradients within the biome, it is more appropriate to represent this benchmark as a range. The data from these exclosure sites support a reference range of 3.0 to 6.0 m²/ha.
Basal Area (m²/ha) as a measure of woody vegetation structure in arid agroecosystems.
Basal Area is a measure of the cross-sectional area of woody vegetation per hectare, indicating ecosystem structural health in arid shrublands under agricultural crop production.
Long-term grazing exclosures in Acacia aneura shrublands provide the best available proxy for a high-health woody vegetation structure in the absence of degrading land use.
