Vegetation communities in Ozark National Scenic Riverways (ONSR) were mapped at two levels using a hybrid combination of statistical methods and photointerpretation. The primary mapping level is to the highly detailed association level of the USNVC. This map includes 49 cover classes. Twenty-four of these classes relate to USNVC vegetation associations. The remaining types include cultural features, non-vegetated features, and ruderal communities on abandoned agricultural lands. Overall map classification accuracy is 63 percent. The secondary mapping level combines communities with similar appearance and ecologically related communities into Community Types, which are subunits of even more broadly defined Ecological Systems. Ecological Systems and Community Types identified for this project aided mapping to a much greater extent than alliance-level mapping and are more relevant to resource management within the park. This map includes 33 classes and overall classification accuracy is 77 percent. The scale of both maps is 1:24000, and the grain of the raster-formatted vegetation map is 10 by 10 meter grid cells. Spatial accuracy is less than or equal to fifteen meters.
