As the initial step in a study of forest fire cycles in the boreal forest of northwestern Ontario, four burned areas of different ages were briefly examined. This Report describes the present condition of the areas visited in terms of both forest cover and vegetation. Tentative hypotheses on the role of fire in this region of the boreal forest are put forward and several questions raised about the interactions among the main tree species. Apparently, in most cases the same dominant tree species return immediately after fire, implying that cycling by fire rather than succession is the basic mechanism in this forest. Proposed further work to complete this study is described and the hope expressed that similar studies will eventually be undertaken in other parts of Canada.
