Evidence & Context
A Basal Area approaching or exceeding 5.0 m²/ha can be confidently identified as the upper detrimental threshold for a functional cropping system in this biome.
Basal Area (BA) is the sum of the cross-sectional area of tree stems at breast height per hectare.
This benchmark marks the maximum basal area beyond which cropping becomes unsustainable due to competition for water in the biome.
Empirical studies of tree-crop competition and yield loss in low-rainfall agroecosystems support this threshold.
