site index Natural History Series page 39,000 ACRES OF ELBOW ROOM! Our first Natural History series trip for 2002 took us to the Nature Conservancy's Tallgrass Prairie Preserve near Pawhuska, Oklahoma on May 21. It is the world's largest single tract of tallgrass prairie not in private ownership. Eventually, most of this property will become open bison range. Right now, about half of it is still stocked seasonally with cattle, as it was for decades during its prior existence as the Chapman/Barnard Ranch. The other half is home to nearly 2,000 bison!
Recent rains produced a delightful variety of wildflowers, including spider milkweed, antelopehorn milkweed, pale poppy mallow, larkspur, daisy fleabane, violet oxalis, rose verbena and marbleseed. The flower-finding was so rich, we hated to leave! But, we hit the road again and made our way down to Pawhuska for lunch and a look at the historic downtown area. After lunch, we drove up to the Preserve. Public roads enter the property from the north, west and south. Signs next to the cattle guard crossings advise visitors to remain in their car when entering the bison range. As we drove along, we watched for the bison herd, and spotted several hundred of them on a ridge about 1/4 mile west of the road. Unfortunately, that was our best view of the bison on the trip!
The path back led us through a valley with cross-timbers oak forest. Huge bur and chinquipin oaks made an impressive canopy. The forest floor had a quality assortment of understory plants also.
We spent the night in Independence and got an early start the next day. We drove out to Elk City Lake to hike part of the 15 mile nature trail on its north shore. This trail can be accessed at either end or in the middle. We opted to start in the middle and walk east. The trail largely stays on contour, winding among huge hunks of the limestone ledge which makes the caprock on the north side of the lake. Columbines grew from crevices in the sides of these blocks, making for an interesting hanging garden. A summer tanager and a late flock of cedar waxwings livened up the canopy overhead.
