You plant once and harvest once a decade, so the returns are locked in by the small silvicultural calls made in between. A point of extra survival, a season of weed control, a millimetre of daily height: tracked over ten years, those are the levers that decide the crop.
The share of planted seedlings that establish and hold through to canopy closure — the foundation every later metric is built on.
Living stems standing per hectare at clearfall — how much of the planted density carried a merchantable stem to the mill.
Dominant top height by age — blue gum's headline growth trait, and the earliest read on site quality.
How evenly diameter is spread across the stand — a tight distribution means fewer suppressed stems and a cleaner harvest.
Total standing volume divided by stand age — the single number the whole rotation is planned around, and the one that sets the harvest date.
Merchantable stem volume accumulated per hectare — the raw stock the harvest converts into green tonnes.
Cross-sectional stem area per hectare — the density gauge that tells you whether the stand is fully using the site or crowding itself.
Where current annual growth falls back through the running average, mean increment culminates — the biologically optimal moment to clearfall.
How harvest volume splits across log grades — sawlog, pulpwood and residue. In a short-rotation pulp crop the premium sawlog fraction is small, and it sets the ceiling on long-term carbon storage.
Crown lost to Mycosphaerella and Teratosphaeria leaf blight — blue gum's chief growth thief, worst in the wet establishment years.
Standing crop lost to wildfire each year across the estate — the tail risk that a decade of growth is exposed to right up to harvest.
Young seedlings browsed by kangaroos and wallabies in the first summer — controllable, and cheap to fix compared with a replant.
The stall in stem growth through the hot, dry Mediterranean summer — deep-soil moisture is what carries the crop across it.
Everything it costs to put a green metric tonne on the mill weighbridge — your breakeven, independent of the export chip price.
The blended price your green tonnes actually earn at the mill or chip terminal — margin per tonne starts against your breakeven.
Rotation margin spread back across the years it took to grow — the annualised figure that lets forestry stand next to any other land use.
The discount rate at which the rotation's discounted costs and revenue break even — how forestry is judged against every other investment.
Carbon dioxide locked into standing biomass and roots over the rotation — a co-product the crop banks every year it grows.
Where the carbon in the harvested wood ends up — locked into long-lived timber, or in pulp and paper that releases it within a few years. Grade decides the split.
Wood volume grown per megalitre of rainfall used — the true measure of productivity in a catchment where every tree draws on the water balance.
