Evidence & Context
The functional ranges for basal area in Australian arid grazing woodlands, based on this synthesis of evidence, are summarized in Table 1.
The range of basal area representing a balanced tree-grass savanna or open woodland supporting sustainable pastoral productivity.
Optimal functional range of basal area for sustainable grazing and ecosystem health in arid grazing woodlands.
This range represents a dynamic equilibrium actively maintained by best-practice management balancing woody overstorey and herbaceous understorey.
