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.

Tree Height Meters (m)

Required number input.

Live Crown Meters (m)

Required number input.

Height above ground of live-crown base from tree height minus live crown length. 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]

Base Height Meters (m)

The resulting base height meters returned as a number.

• Canopy cover, gap fraction, LAI, and light attenuation depend on sensor view, clumping, leaf angle, woody material, sun angle, extinction coefficient, season, and understory. Beer–Lambert inversion is model-dependent.
• 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.

• Crown Ratio

  Live crown length as a percentage of total tree height.

• Basal Area Single Tree

  Tree stem cross-sectional basal area at breast height in square metres from DBH in centimetres.

• Canopy Cover Percentage Forestry

  Canopy-covered projected ground area as a percentage of total sample plot area.
