Title: Response of 55-year-old lodgepole pine to thinning.

Author: Barrett, James W.;

Date: 1961

Source: PNW Old Series Research Note No. 206, p. 1-8

Publication Series: Scientific Journal (JRNL)

Description: Does lodgepole pine (Pinus contorta) as old as 55 years respond to thinning? Very little research has been done to answer this question for central Oregon stands because until recently they have been considered largely unmerchantable. Now, however, this species is recognized as a good potential source of pulpwood and small saw logs, and information is needed on growth and yield of thinned as well as unthinned stands. This note presents results from a 22-year record of a thinning experiment on the Pringle Falls Experimental Forest in central Oregon.
