Stocking at harvest

950 stems/ha

Living, merchantable stems standing per hectare at clearfall. In an unthinned pulpwood regime this is planted density minus establishment losses and later self-thinning of suppressed trees.

The benchmark

Unthinned WA blue gum pulpwood stands are planted at roughly 1,000–1,250 stems/ha and carry most of that to clearfall, mortality aside.

What it signals

Stocking is the bridge between how many trees you planted and how many green tonnes you sell. Read against basal area it tells you whether the site is fully occupied or whether competition has thinned the stand back toward its carrying capacity.

Data required to calculate
Live stems at final inventoryno.Net planted areaha

Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.

How to improve it
01

Hold establishment survival high so the stand starts fully stocked.

02

Match planting density to site quality to limit later self-thinning.

03

Keep firebreaks and access maintained to protect stocking to harvest.
