The ability to assess wood quality using longitudinal compression strength U(S) of plugs removed from along the length of a tree stem was assessed in ponderosa pine damaged to varying degrees 4 years earlier in a prescribed burn. LCS has been used elsewhere to estimate residual strength of utility poles and might be a simple method for assessing wood quality in standing trees. The degree of stem char on fire-killed trees had a significant effect on [CS values. LCS values of plugs from charred portions of fire-killed ponderosa pines were greater than those from uncharred portions of fire-killed ponderosa pine trees. LCS might he a useful tool for forest managers assessing the remaining flexural properties of standing dead limber after fires.
