area -- regeneration after fire -- mature stands

Аннотация: In August 1940 a 16-square-mile area on the Little Pabos River limits of the Gaspesia Pulp and Paper Company was burned over. The fire ran through recently cut-over areas, some 10- to 20-year-old stands, and some mature stands. 20 years later the burn was obviously restocking so slowly that production in the area would be greatly reduced for at least one rotation. The study of forest development after the 1940 Little Pabos fire is the subject of this paper. Stocking, distribution, growth, age and the establishment of balsam fir, spruce, and white birch after fire are described and discussed
