The Tallgrass Prairie Preserve is a remnant of what once covered over 142 million acres in parts of 14 states. Less than 10% of the original tallgrass prairie remains, with the only large unbroken tracts in the Flint Hills of Oklahoma and Kansas. The Nature Conservancy, a private, nonprofit conservation organization purchased the 29,000 acre Barnard Ranch in 1989 to establish the preserve. The preserve now consists of 38,700 acres which The Nature Conservancy owns or leases in Osage County, Oklahoma.
One of Oklahoma’s little-known treasures lies north of Pawhuska near the Kansas border.
