From tree measurements to board feet
Timber cruising estimates volume before harvest for sale negotiation and harvest planning. Volume equations translate DBH and height into cubic meters or board feet by product class.
Cruising methods
100% tally on small sales — every tree measured. Sample cruise on large tracts — statistical confidence from plot frequency and variability.
Product sorting
- Sawlogs — minimum diameter and length for lumber mills.
- Pulpwood — smaller stems for paper and chip products.
- Biomass — tops and residues for energy or mulch markets.
Defect deduction
Cull rules subtract volume for rot, sweep, forks, and broken tops. Accurate defect coding prevents overestimation that disappoints buyers and underpayment to landowners.
