Quantitative Analysis by the Point-Centered Quarter Method
نویسنده
چکیده
This document is an introduction to the use of the point-centered quarter method. It briefly outlines its history, its methodology, and some of the practical issues that inevitably arise with its use in the field. Additionally this paper shows how data collected using point-centered quarter method sampling may be used to determine importance values of different species of trees and describes several methods of estimating plant density and corresponding confidence intervals. This paper is a significant revision of a 1999 online document intended for student use at Hobart and William Smith Colleges. A number of individuals elsewhere found the earlier version helpful and had additional questions that I have tried to address in this revision.
