Forest cover plays an important role in modifying the severity and frequency of natural soil mass wasting. Removal of the forest cover through forest harvesting and the associated engineering operations can alter natural processes and aggravate inherent instability. In the Queen Charlotte Islands, steep slopes, finely textured soils, frequent seismic activity, heavy precipitation, shallow rooting tree species, and high winds predispose the area to a high natural level of mass wasting. This preliminary appraisal reviews current silvicultural operations in the Islands and proposes alternatives. Traditional silvicultural systems are described and constraints imposed by the local conditions identified. Naturally occurring forests on the Queen Charlotte Islands are compared to projected managed forests that will replace them, and successional processes and their influence on mass wasting events are discussed. The report concludes by noting several research opportunities in the study of silviculture and mass wasting.

Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.

Surface erosion and mass wasting in forested watersheds can increase significantly following road development and logging. This is particularly true on steep forested slopes that receive a great deal of precipitation, such as those on the Queen Charlotte Islands. Through proper planning and the use of high construction standards, many of these problems can be alleviated, but not completely controlled. In addition, unforeseen problems that result in accelerated surface erosion and mass wasting may arise. For these reasons, the forest manager must have a variety of measures to either control erosion or lessen its impacts. This report reviews both prevention and rehabilitation techniques that may be of use in controlling erosion and/or alleviating further erosion damage on the Queen Charlotte Islands. To date, little erosion control or land rehabilitation work has been carried out on forested land on the Charlottes, and it is hoped that this report may provide the basis for future activities in this field.

The intent of this report is to present the most current and available information concerning establishment and growth of redcedar in the coastal region of British Columbia. The first three sections introduce the approach to the report and summarize well-known information about the redcedar resource and the uses of redcedar products. The silvics section describes morphological and reproduction characteristics, tolerance, damaging agents, growth development patterns, and genetics and summarizes several studies investigating redcedar stem form and root characteristics. The ecology section describes climatic amplitude of redcedar, its occurrence within biogeoclimatic units, edaphic amplitude, and associated tree species. The silviculture section includes management- related topics such as growth and yield, regeneration strategies, and intensive silviculture options.--Document.
