Power laws are interesting patterns that exist over wide ranges. Power laws may be used to determine the organization of countless networks in nature. The purpose of this study was to test whether the distribution patterns in shoot lengths of three popular tree species follow a power law. This study not only adds to the general knowledge base for these species but also may be used to make predictions about other species. Three common tree species were included in this study: loblolly pine (Pinus taeda), redmaple (Acer rubrum), andthe sugar maple (Acer saccharum). The height and all shoot lengths of five individuals of each tree species were measured, recorded and sorted. Loblolly pines and sugar maples followed the same power law at individual and species level. Most of the red maple individuals did not follow a power law although they followed a power law at the species level. One possible reason might be that the redmaple trees measuredwere too young and were in strong competition for resources with other tree species.
