Abstract:

A procedure is presented for mapping tree locations directly into a Cartesian coordinate system without requiring distance and bearing measurements in the field. An independent check of the locations of 401 trees by different field crews at different times showed the method to be both accurate (with an average difference between the two measurements of 0.01 m) and precise (with the standard deviation of the differences being 0.22 m). The method is most efficient with a three-person crew. The time required to map a given area is dependent on tree density and visibility. In well-stocked (600 to 1100 trees/ha) northern hardwood stands it is possible to map 1 hectare per day with an experienced crew. The procedure is designed for square plots, but it can be adapted easily to circular plots. For. Sci. 35(3):657-662.
