This review, based on information from 169 references, analyzes the problem presented by logging slash, and its importance. It discusses eight factors which affect the slash hazard, and describes nine methods to abate it. Legislation governing the treatment of slash in Canada, and part of the United States, is presented. Some of the silvicultural effects of slash, and of different methods of its disposal, are discussed. Costs of some slash disposal operations are given. Present research efforts to provide a better understanding of the problem, and how to combat it, are described. The general conclusion is that the slash problem, and its solution, deserve much greater attention than they now receive, particularly in eastern Canada.
