Résumé : | Lodgepole pine (Pinus contorta Loud.) is a major asset of the United States and Canada. Where other tree species do not prosper, this species is thrifty in spaced even-age stands. When grown to diameters 25 cm or to tree ages 80 years, lodgepole pine is at risk of mortality from beetle attack and wildfire. Stands are best maintained by precommercial cleaning of regeneration, intermediate commercial thinning, commercial and clear-cut harvesting before 80 years. In stands so managed, water yields and quality, forage yields, and recreational values need not be more at risk than from insect-caused mortality and subsequent wildfire. Wildlife is affected by both natural and man-caused perturbations. |
