Title: Estimating past diameters of several species in the ponderosa pine subregion of Oregon and Washington.

Author: Spada, Benjamin.;

Date: 1960

Publication Series: Miscellaneous Publication

Description: In certain kinds of forest growth studies, an estimate of diameter outside bark is required for trees as of some previous date. Previously, papers were published by this Station regarding estimation of past diameters of Douglas-fir and ponderosa pine. Since they were issued, new and more complete data have been collected for most of the major species in the ponderosa pine subregion as part of the Forest Survey inventory program.
