forest inventory plot
Sample plots are put within the various forest types. The purpose of the inventory is to classify forests using aerial photos based on ground samples. It requires walking long distances to get to a randomly selected location prior to crews being sent in to the field. The crew measures the distance along the prescribed bearing to the spot where the first of six plots were established. At each plot location, the crew collects information such as tree species, numbers, diameters and heights (to determine the volume of wood in the forest) and the health of the trees and understory.
