The middle Niobrara River Valley of north-central Nebraska is of significant biogeographic importance due to the interaction of geologic and hydrologic features which provide habitat for species of eastern, western, and boreal affinities. Vegetation data collected from 10 herbaceous and 13 woody sites within the Niobrara Valley Preserve and adjacent areas were ordinated using BCORD. Results corroborate a previous literature review and TWINSPAN classification analysis which described seven major community types for this region: Sandhill, Mixed Prairie, Tallgrass Meadow, Upland Pine, Juniper, Hardwood, and Streambank Communities.
