Title: Early height growth of ponderosa pine forecasts dominance in plantations

Author: Oliver, William W.; Powers, Robert F.

Date: 1971

Station ID: RN-PSW-250

Description: Future crown class may be determined well in advance of intertree competition in plantation grown ponderosa pine. Regardless of site quality, dominant trees in 10 California plantations reached breast height ½ year sooner than codominants and 1-½ years sooner than intermediates. Dominant trees on poor sites reached breast height several years earlier than has been reported for natural stands. Failure to recognize this rapid early growth will result in underestimating site index in plantations. Relative height is recommended as a guide in marking thinnings or Christmas tree cuttings.

Keywords: Pinus ponderosa, plantation stands, crown class prediction, pre-commercial thinning
