Abstract

Diameters, heights, and eight crown radii per tree were measured on 75 individuals from each of seven bottomland hardwood species in Mississippi. It was determined that the seven species could not be described by a single regression equation. Crown class was tested to see whether it significantly influenced the slope or intercept of the linear relationship. Three of the species were significantly affected. Total height was not a significant predictor of crown width. Regressions of average crown radius on d.b.h. were calculated for each species or species-crown class group. Roundness of crown was not affected by species but average crown radius/d.b.h. was. The crown width/d.b.h. relationship can be applied to competition studies and in predicting d.b.h.`s from aerial photographs.
