Abstract

Randomized branch sampling (RBS) is a special application of multistage probability sampling (see Sampling, environmental), which was developed originally by Jessen [3] to estimate fruit counts on individual orchard trees. In general, the method can be used to obtain estimates of many different attributes of trees or other branched plants. The usual objective of RBS is the estimation of a total quantity for a tree or a branch, for example, woody dry matter or volume [5], leaf dry matter [2], or counts of tree-inhabiting insects [1]. RBS also has potential application in the estimation of attributes of river networks (see Rivers, canals and estuaries) and other branched structures. Here, our interest is restricted to the above-ground portions of trees.
