Application of silvicultural systems in the B-19 foothills region of Alberta. Lees, John Crawford

Abstract

The application of silvicultural systems in the B-19 Foothills, region of Alberta was examined in the light of current problems in management, silviculture, and utilisation. Following a regional description, in which a classification of site is developed, certain silvicultural systems were examined and recommended for the dominant stand types which occur on three major site groups, viz:- 1. Dry Upland 2. Moist Transition 3. Wet Consideration was given in each case to clearcutting, shelterwood and selection systems. Recommendations were based on the information presented in the preceding chapters and that available in those references cited in the bibliography. It has been pointed out in conclusion that there are three main phases in the development of control of the silviculture and management of the region. These are:- 1. The preparation of management plans for sustained yield. 2. The selection of silvicultural systems to, bring silvicultural control into the framework of sustained yield management. 3. The development and application of cultural treatments through research to improve local conditions and to help solve particular regeneration problems. The importance of the hypothesis presented in Chapter III is finally re-stressed with reference to the above mentioned development phases. That is - That there are already available to the practising forest management planner, silvicultural systems which are applicable, with or without further adaptation, to the forest stands of the region and to the sites described. Certain fields of research have been suggested throughout the text and these were summarised in a final recommendation.
