- Title
SPEED AND ACCURACY OF METHODS FOR OBTAINING MEASUREMENTS OF FORESTS.
- Authors
Patterson, C. Joan; James, Douglas A.
- Abstract
Point-quarter, random-pairs, 0.004-ha-arm-length-rectangle, and 0.04-ha-circle methods for sampling density, diameters, and size categories were used in an oak-hickory (Quercus-Carya) woodlot. Results from three trials for each method were compared to actual density of trees determined from a total count of trees in the woodlot. With respect to accuracy per time spent, the 0.04-ha circle was the best method and the point-quarter method was the worst. These findings improve on previous studies because, for the first time, repeated trials in the field were employed.
