Abstract
The site-class curves presented . . . for the irregular pine-fir forests of California, were first prepared in connection with a yield-predicting procedure . . . developed in 1933. The original curves were designed principally for administrative use of the Forest Service in Region 5. Since they have now come to be accepted by other agencies and for general purposes, this research note has been prepared to make the curves more readily available and to describe their peculiar features sufficiently to enable correct application. It is hoped that this action may contribute to the establishment of a single criterion of site for the region as nearly as possible like that most commonly used in volume surveys, growth forecasting, and other forestry work.
