Operations at the Tallgrass Prairie National Preserve (Preserve) are coordinated between both the NPS and TNC. This means that the functioning of ranch and Preserve operations including the preservation of cultural and natural resources, are all provided through the combined efforts of this unique partnership. Some specific results of this collaborative approach to management include the establishment of over 41 miles of hiking trails, a catch and release fishing program on a number of Preserve ponds and creeks, patch burning and grazing management to provide a shifting mosaic of diverse prairie habitat, reintroduction of bison after a more than 150-year absence, establishment of native prairie on previously disturbed ground, and engagement in citizen science programs, such as an annual butterfly count. Visitor services include an on-site visitor information station, interpretive programs (e.g., guided house tours, bus tours, special interpretive programs along with ranger-guided hikes), and an extensive list of special events and activities throughout the year. TNC has re-acquired all mineral rights to the Preserve, forever protecting the historic landscape. TNC manages the cattle leases associated with the ranching operation.
