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.

Leaf Square Meters (m2)

Required number input.

Canopy Cubic Meters (m3)

Required number input.

One-sided foliage area per occupied canopy volume, in m²/m³. 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]

Leaf Area Density (m2/m3)

The resulting leaf area density 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.

• Canopy Bulk Density Forestry

  Canopy bulk density in kg/m³ from dry available canopy fuel mass and occupied canopy volume.

• Leaf Area Index Forestry

  One-sided leaf area index: measured one-sided leaf area divided by ground plot area.

• Light Transmission Beer Lambert Forestry

  Beer–Lambert canopy light transmittance exp(-k·LAI) from extinction coefficient and leaf area index.
