Some methods of sampling triangle based probability polygons for forestry applications

Some methods of sampling triangle based probability polygons for forestry applications

There is interest in forest sampling methods which have the ability to provide reliable estimates of volume without incurring unreasonable costs. Fraser (1977), to this end, described an individual tree variable probability sampling method which selects sample trees with probabilities based on the a...
