Popis: | Northern red oak (Quercus rubra L.) has been described as an opportunistic, pioneer species adapted to mesic sites, though its presence and site-specific occurrence in extreme soil-water conditions is not well understood. Fifty woodlots were investigated for the presence of Q. rubra on the Maumee lake plain of southeastern Michigan. Although it was found widespread geographically, Quercus rubra was observed only in dry-mesic to mesic ecosystems where adequate moisture remains throughout the growing season on sand, sand/clay, and clay lake plain landforms. Quercus rubra was absent in sand lake plain ecosystems of nutrient-poor, deep sand (>200 cm to clay), and from high sand ridges that were not adjacent to swampy depressions. Within the sand lake plain it was observed only on relatively mesic, well- to somewhat poorly-drained ecosystems. In all landforms, Q. rubra was absent in seasonally inundated depressions. Successful overstory recruitment of Q. rubra was very rare, with the exception of a si... |
