Inventory and Monitoring Networks of the National Park Service are charged with collecting and reporting data related to the status and trends of key natural resources. We have analyzed a suite of grazing data from 1995- 2016, fire history data from 1998-2015, and vegetation community data from 2002-2014 to better understand trends as they relate to management strategies at the preserve over time. We found that cattle stocking rates declined and fires became less frequent over the latter half of the record. Similarly, bare ground declined, woody species increased slightly, and the floristic quality index was relatively stable with a decline in 2014. Although it is difficult to directly infer cause and effect from our monitoring design, the data are valuable for helping park managers evaluate their goals and develop future action plans.
