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.

Trees Per Hectare (1/ha)

Required number input.

Dominant Height Meters (m)

Required number input.

Mean tree spacing as a percentage of dominant height, using sqrt(10000/N) for N stems per hectare. 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]

Relative Spacing Percent (percent)

The resulting relative spacing percent returned as a number.

• Density, spacing, stocking, and plot-expansion metrics depend on species or stand model, plot area, edge correction, diameter threshold, spatial pattern, and reference maximum. They are not interchangeable measures of competition.
• 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.

• Relative Density

  Observed stems per hectare as a percentage of a supplied reference stand density.

• Dominant Height

  Mean height of a selected dominant-tree sample from summed heights and sample tree count.

• Trees Per Hectare From Plot

  Estimated stems per hectare from tree count in a measured plot area.
