Abstract
The ability of two relatively new statistical methods to quantify spatial patterns of forest trees was tested on seven stands of naturally regenerated loblolly pine. Both Greenwood's statistic and reflexive neighbor properties were calculated for each stand. All seven stands were found to be composed of clumps of trees with trees randomly distributed within the clumps. Greenwood's statistic is sensitive to the spatial arrangement of just the sample trees, but reflexive neighbor relationship analysis is sensitive to the spatial arrangement of both the sample trees and their surrounding neighbors, hence, spatial pattern is assessed in greater detail by using both statistics. Both statistical techniques are easy to use and require no prior knowledge of stand density or variability. Forest Sci. 29:514-518.
