Middle and High Elevation Coniferous Forest Communities of the North Rim Region of Grand Canyon National Park, Arizona, USA

Résumé du livre

We examined the composition and structure of forest communities in a 3700 ha watershed in relation to environmental gradients and changes in land management practices. ... However, widespread regeneration of A. concolor following possible changes in the fire regime in the late 19th century is producing a more homogenous mixed-confier forest with greater horizontal and vertical continuity of fuel. This shift toward landscape homogeneity not only may adversely affect biodiversity, but also may be perpetuated as the probability of large, high-severity fires inceases with continued fire suppression.
