A surplus of dry dust and ash is kicked up as a herd of bison react to the presence of employees of the Nature Conservancy who, along with help from volunteers and neighbors, cull 110 yearling and two-year-old bison at the Niobrara Valley Preserve, which is located 16 miles north of Johnstown, Neb. Traditionally, the herd is culled in late October, but the recent fires in the area have destroyed more than half of the grazing land, which provides feed. The culled bison will be sold to a feedlot. | On assignment for the Omaha World-Herald
