[Annotation copied from Lynham et al. 2002(] This report describes the early changes in the diversity indices of three vegetation strata following partial logging and experimental burning in pine-mixedwoods. Shannon's diversity index was used in this study. The diversity index was found to be independent of sample size once the sample size had reached a certain minimum. After partial logging, the diversity decreased in the tree and shrub strata. There was a general increase in the diversity of the minor-vegetation stratum following logging. Following experimental fires, the diversity of the shrub stratum was reduced to zero simply by the temporary removal of the stratum. A decrease of about 50% occurred in the diversity of the minor-vegetation stratum following burning. The diversity loss will continue for decades in the tree stratum and for several years in the shrub stratum, whereas diversity of the herbaceous stratum is estimated to reach the prelogging and preburn levels after five to eight years.
