The Niobrara Valley supports exceptional biological diversity within its narrow confines, where elements of the following ecosystems exist in the same area or very close to each other: northern boreal forest, ponderosa pine forest and savanna, eastern deciduous forest, tallgrass prairie, mixed-grass prairie, and sandhills prairie. Approximately 160 species of plants and animals found in the Niobrara Valley are at the edge of their range. Some plant and animal species are state or federally listed as rare, threatened, endangered, or candidate species.
