Waterhouse, M. J. | Baleshta, Karen E. | Nemec, Amanda F. Linnell (Amanda Frances Linnell)
A uniform shelterwood systems trial was established in 1990 to test overstorey tree retention levels required to naturally regenerate Douglas-fir (Pseudotsuga menziesii var. glauca) on forest-prone sites in the Dry Warm Sub-Boreal Spruce (SBSdw) biogeoclimatic subzone of central British Columbia. Two or three harvest entries were used to create combinations of preparatory and regeneration cuts that affected seedfall and vegetation, plus density and growth of both natural and planted Douglas-fir regeneration...The shelterwood silivicultural systems tested in this study provide foresters with several options to establish and grow Douglas-fir regeneration to meet land management objectives.
