Gross yield and mortality tables for fully stocked stands of Douglas-fir.

Abstract

Increasing interest in the practice of intensive forestry has demonstrated the need for gross yield tables for Douglas-fir showing the volume of trees that die as well as volume of live trees. Net yield tables for Douglas-fir, published in 1930, give the live volume in fully stocked stands at different ages on different sites. As in all normal yield tables, no accounting is made of the volume of trees that die as stands grow older. Presented here are gross yield tables, which include net yield and estimated mortality volume. Mortality 13 tables constructed in the process of making the gross yield tables are also presented.
