Accuracy of Two Ground Survey Methods for Assessing Site Disturbance

The accuracy of successive estimates of site disturbance using two ground survey methods was evaluated. Results from the point transect and grid point intercept methods were compared with those results from an intensive 1x1 m grid survey over a 4 ha study area. The point transect method, using a transect spacing of 30 m, provided the most accurate and consistent estimate of disturbance in the study area.
