The Black Mountains are named for the spruce-fir forest in the southern Appalachian Mountains that are an eco region of what sort of biome?
Black Mountains (North Carolina) The Black Mountains are a mountain range in western North Carolina, in the southeastern United States. They are part of the Blue Ridge Province of the Southern Appalachian Mountains. The Blacks are the highest mountains in the Eastern United States. The range takes its name from the dark appearance of the red spruce and Fraser fir trees that form a spruce-fir forest on the upper slopes which contrasts with the brown (during winter) or lighter green (during the growing season) appearance of the deciduous trees at lower elevations. The Eastern Continental Divide, which runs along the eastern Blue Ridge crest, intersects the southern tip of the Black Mountain range.
North American Prairies Province The North American Prairies Province is a large grassland floristic province within the North American Atlantic Region, a floristic region within the Holarctic Kingdom. It lies between the Appalachian Province and the Rocky Mountains and includes the prairies of the Great Plains. It is bounded by the Canadian coniferous forests on the north and the arid semideserts to the southwest. The province itself is occupied by temperate grasslands, savannas, and shrublands (including such ecoregions as the Flint Hills tall grasslands, Sand Hills, High Plains). Endemism is rather limited in this province, and its boundaries are vague. During the Pleistocene much of the province was glaciated.
