Forest Tree Density Sampling Method

Description

Forest tree density sampling can be done with the point-centered quarter method. This field method helps measure the density, frequency, and coverage of tree species in a forest. It also helps estimate how many individual trees are present, how often a tree species appears, how common it is compared with other trees, and the...
