Biomass Equations for Southeastern Ohio Forest Trees

Author Institution: Division of Forestry, The Ohio State UniversityBiomass equations for total tree weight above stump were developed for 8 Ohio forest tree species or species groups. Of the predictor variables tested by multiple linear regression, diameter squared at 1.4 m above ground (d.b.h.) was the most consistent significant variable. R2 for the species ranged from 0.80 to 0.96. Species equations were not significantly different. The combined equation for all species was: Total green weight, kg = —100.3 + 0.9628 (Diameter, cm at 1.4 m above ground)2
