Preliminary soil-site studies in the western white pine type

Abstract

A guide for estimating site quality on bare, cut-over, or burned-over lands in the western white pine type is needed for planning the management of these lands. On many areas trees may be entirely lacking or an insufficient number in the proper crown classes remain on which reliable site index determinations can be based. Therefore, reliance must be placed on some method other than tree measurement to provide an insight into the probable growth potential of a given area. This paper presents results of a limited study of the relationships of soil characteristics to site index of western white pine in an effort to establish a tentative site quality rating system based on soil characteristics. Relationships of site indices of white pine and associated species are also presented. These relationships must necessarily be confined to the white pine type in which they were determined.
