Abstract

Horizontal point sampling is sometimes difficult to use in dense stands of small-diameter stems because of poor visibility. One solution to this problem is to use vertical point sampling in the field to obtain a larger than necessary preliminary sample. The diameter and distance of each tree in the vertical point sample is measured, and then a computational procedure identical with horizontal point sampling is used to subsample the vertical point sample tree list. For the method to work, it is necessary that the horizontal point sampling criterion be at least as limiting in a certain sense as the vertical point sampling criterion. Our principal result is to show how this necessary condition can be met.
