Comparison of Overstory Canopy Cover Estimates on Forest Survey Plots

摘要

Two methods of overstory canopy cover assessment currently in use by Forest Survey field photo and calculated, were compared to two alternate methods, stereo plotted and line-intercept. The line-intercept method was used as the control. The number of transects needed to obtain a reasonable estimate of overstory canopy cover is time consuming, so if there are time constraints, then field photo estimates of cover are the preferred alternative for Forest Survey.
