Title: Logging production rates in young-growth, mixed-conifer stands in north central California

Author: McDonald, Philip M.;

Publication Series: Research Paper (RP)

Description: To quantify production rates for small trees, this study examined the components of log-making and tractor yarding at the Challenge Experimental Forest, Yuba County, California. Rates were calculated over a range of 12 to 40 inches d.b.h. The rate for incense-cedar was lowest; for ponderosa pine it was intermediate; and for Douglas-fir, white fir, and sugar pine combined, it was highest. Log size strongly influenced production. For log-making, production for 38-inch d.b.h. trees was two and a half times that for 14-inch d.b.h. trees; for yarding, production for a turn of logs averaging 22 inches d.i.b. was two and a half times better than that for one averaging 12 inches d.i.b.

Keywords: logging production, logging costs, young-growth stands, California (north central), Pinus ponderosa, Pseudotsuga menziesii, Abies concolor, Pinus lambertiana, Libocedrus decurrens
