The spread of stem diameters across the stand, expressed as a coefficient of variation. A low figure means the trees are growing evenly; a high one means a wide gap between dominant and suppressed stems.
Even-aged eucalypt pulp stands typically run a diameter coefficient of variation of 15–25%; tighter distributions carry fewer suppressed, unmerchantable stems.
Forest Products Commission WA ↗Uniformity drives harvest economics: a stand of even stems yields more merchantable tonnes per hectare and cuts faster with less waste. A widening distribution flags patchy establishment, competition or nutrition that is leaving trees behind.
Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.
Start uniform — even seedling grade and consistent planting spacing.
Keep weed control even across the compartment, not just the edges.
Correct patchy soil fertility with targeted, mapped fertiliser.
