Evidence & Context
The Lower Critical Threshold is identified as approximately 0.5 m²/ha. Landscapes with a Basal Area falling below this value are considered to have crossed a critical tipping point.
Basal Area as a measure of tree stand structure and function.
This benchmark represents the minimum Basal Area below which woodland ecosystem function collapses, risking a shift to a treeless state.
Based on ecological collapse and loss of essential ecosystem services below this threshold.
