Evidence & Context
The optimal functional range for co-beneficial outcomes is estimated to be 2-8 m²/ha.
Basal area (BA) is a standard forestry metric that quantifies stand density by summing the cross-sectional area of tree stems at a standardized height (typically 1.3 m) over a given area, expressed as square metres per hectare (m²/ha).
The optimal basal area range of 2 to 8 m²/ha supports a balanced, resilient arid karstic woodland under livestock grazing, maintaining woody structure and pasture productivity.
The optimal functional range is derived from synthesis of lower and upper thresholds based on ecological and management interpretation.
