Title: Height intercept for estimating site index in young ponderosa pine plantations and natural stands

Author: Oliver, William W.;

Date: 1972

Source: Res. Note PSW-RN-276. Berkeley, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Forest and Range Experiment Station. 4 p

Publication Series: Research Note (RN)

Description: Site index is difficult to estimate with any reliability in ponderosa pine (Pinus ponderosa Laws.) stands below 20 yeas old. A method of estimating site index based on 4-year height intercepts (total length of the first four internodes above breast height) is described. Equations based on two sets of published site-index curves were developed. They worked equally well for plantations and natural stands in northern California.

Keywords: Pinus ponderosa, site-index estimation, California (northern), height intercept method, internodal measurement
