Survey of forest regeneration in the Nimpkish Valley of British Columbia and recommendations for future management. Bunce, Hubert William Ferdinand

Abstract

Logging has proceeded continuously since 1915 in the Nimpkish valley. The cutting has been of the old-growth Douglas fir (Pseudotsuga taxifolia (Poir.) Britt, western red cedar (Thuja plicata Donn.), western hemlock (Tsuga heterophylla (RAF.) Sarg.) and balsam fir (Abies amabilis (Bougl.) Forbes. Many of the areas cut have become restocked naturally with various species of trees which are classified as second-growth. The excess of low-value trees and the slow rate of regeneration are not economically satisfactory. Since 1924 various plantations have been established. A study of the results of this natural regeneration and this artificial regeneration indicates practical methods for future procedure. Additional information comes from experiments that have been completed, and from those that are still in progress. The synthesis of the collected material and the silvicultural discourse form the basis for recommendations for future management of forestry operations in the Nimpkish valley.
