| The Sheyenne National Grassland, in southeastern North Dakota, supports sandhill prairie vegetation that is interspersed with native woodlands. Woodland ecosystems are located on the bottomlands of the Sheyenne River and are also established as upland groves. The objectives of this study were to classify native woodlands into habitat types and to provide descriptions of topography, soils, and vegetation. An interpretation of patterns and resemblances among macroplots, aided by the statistical tools of nonmetric multidimensional scaling ordination and flexible-beta cluster analysis, differentiated habitat types. Native woodlands in/near the Sheyenne National Grassland were classified into seven habitat types: Tilia americana/Celtis occidentalis, Fraxinus pennsylvanica/Celtis occidentalis, Acer negundo /Vitis riparia, Populus tremuloides/Prunus virginiana, Quercus macrocarpa/Symphoricarpos occidentalis, Populus deltoides/Symphoricarpos occidentalis, and Salix amygdaloides/Symphoricarpos occidentalis. |
