摘要: One of the most striking ecological features mountains eastern United States and adjacent Canada is high elevation forest dominated by needle-leaved, evergreen genera Picea (spruce) Abies (fir). Spruce-fir forests are found on upper slopes Adirondack Appalachian Mountains, over an area that extends from western North Carolina, USA (ca. 35°N), to central Quebec New Brunswick, 49°N). In addition these montane (Cogbill White 1991, Siccama 1974, Harries 1966) or subalpine (MacMahon Andersen 1982) forests, similar spruce-fir dominate some low sites, particularly in northern Canada. Although vary considerably across elevations, latitudes, red spruce (Picea rubens) a dominant tree throughout. fact, restricted Appalachians, Adirondacks, areas and, thus, serves as unifying element varying forests.
