Comparison of logging residue from lump sum and log scale timber sales.

Abstract

Data from 1973 and 1980 logging residues studies were used to compare the volume of residue from lump sum and log scale timber sales. Covariance analysis was used to adjust the mean volume for each data set for potential variation resulting from differences in stand conditions. Mean residue volumes from the two sale types were significantly different at the 5-percent level for the 1973 data but were not significantly different for the 1980 data. These inconclusive findings suggest that the relative efficiency of changing sales procedures should be considered before further study is undertaken.
