Abstract

The regeneration period is a crucial time in the life of a stand because it determines species composition and tree density for the new stand. Silviculturists prescribe treatments to favor adequate and timely conifer regeneration of economically important species that grow well. This paper presents research results that will help silviculturists identify factors favoring natural regeneration of interior Douglas-fir. The data were obtained from retrospective examination of randomly chosen, conventionally harvested stands 3-20 years old in Idaho and Montana. The information covers the Pseudotsuga menzies, Abies grandis, Thuja plicata, Tsuga heterophylla, and Abies lasiocarpa series of habitat types for common harvest and site preparation methods used in the northern Rocky Mountains.
