Forestry & Timber Calculators
Convert tree breast height diameters to basal area metrics, assess merchantable standing lumber volumes, calculate dry carbon dioxide sequestration offsets, analyze canopy light transmissions, and scale stacked cords of firewood.
Canopy Cover & PAR
Translate canopy cover percentage to Photosynthetically Active Radiation (PAR) transmittance and estimate Leaf Area Index (LAI).
Canopy Settings
Typically ranges from 0.5 (conifers) to 0.7 (dense broadleaf deciduous).
Forestry Core Report
Dendrometric / SilviculturalCalculated using the Beer-Lambert extinction formula. Higher LAI indexes indicate multilayered vertical canopy structures.
Forestry Scaling Reference Info
Standard forest diameter values are measured at DBH (4.5 feet / 1.37 meters aboveground). Cords of firewood represent stacked wood, which contains roughly 65% solid wood volume and 35% empty airspace gaps.
