Author: Johnson, Floyd A.;

Date: 1955

Source: PNW Old Series Research Notes No. 112, p. 1-3

Description: Estimates of breast height diameter outside bark for trees as of some previous date are required in certain kinds of forest growth studies. These past diameters may be found by subtracting total diameter growth from known present diameters, where total diameter growth is the sum of wood growth and bark growth.
