• Major export corridors to South African gold/coal mines for treated timber props, and regional sawmills for construction trusses.
Timber Mensuration & Forest Valuation in Eswatini
Timber log measurement in Eswatini forestry relies on Smalian's formula:
V = (π / 8) × (D1² + D2²) × L,
averaging the cross-sectional areas of the small and large ends across the log length.
The forestry industry in Eswatini is dominated by major timber operations in Piggs Peak, Bhunya, and Shiselweni. Calculating clear stumpage values after deducting contract harvesting, forwarding, and roadside haulage provides tree growers and commercial foresters with transparent financial returns.
