Résumé

Old-growth forests are often perceived as cathedral-like stands of large trees in coastal coniferous forests or eastern hardwoods. In most of the boreal region, however, this is not the case, as tree size is limited by cold climate and short growing seasons, while forest age is limited by frequent large natural disturbances. The boreal forest is a disturbance-driven system. Fire is omnipresent and, where it is less prevalent, other disturbances, such as insects and wind, drive forest dynamics. As such, many stands burn or are subject to other disturbances before they have the chance to attain old-growth status. The idea of old growth as a local equilibrium state (i.e., a forest structure that has reached a stable, self-maintaining state in equilibrium with climate and local abiotic conditions), largely developed for other forests, applies poorly to the boreal (chapters 7, 11, and 14). Even when considered over vast regional scales, the probability that a forest burns is not dependent on its age, as young forests have an equal probability of burning as do older ones. Because of the random nature of fire, forest stands of different ages are not equally represented over the landscape (Cumming et al. 1996). Boreal old growth is a dynamic condition that is manifest by varying forest structure (Kneeshaw and Gauthier 2003; Shorohova et al. 2011), stand size, and longevity across the boreal zone of North America. Despite the constraints on old growth in this biome, old growth plays a key role in the maintenance of biodiversity in the boreal forest (chapter 11). © 2018 Andrew M. Barton and William S. Keeton.
