Use this forestry calculation to summarize a measured tree, plot, canopy, fuel, biomass, carbon, growth, density, or wood-volume quantity under a stated inventory convention.

Volume Cubic Meters Per Hectare (m3/ha)

Required number input.

Stand Age Years (year)

Required number input.

Mean annual volume increment from total stand volume and stand age. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Increment Cubic Meters Per Hectare Year (m3/ha/year)

The resulting increment cubic meters per hectare year returned as a number.

• Annual and periodic increments depend on measurement interval, survivor versus ingrowth accounting, mortality and harvest, age basis, site, and volume equation. MAI and current annual increment serve different management questions.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Use locally validated equations and inventory protocols, retain species and measurement metadata, aggregate with appropriate plot expansion and sampling weights, and report uncertainty with stand-level results.

• Current Annual Increment

  One-year volume change between adjacent annual inventories.

• Periodic Annual Increment

  Average annual volume increment between two inventory dates.

• Stand Volume Per Hectare

  Stand volume per hectare from measured total volume on a known plot area.
