Sentinel Ecology and Pyric Herbivory

The purpose of this study is to develop a Strategic Habitat Conservation program to restore heterogeneity of native plant and animal species based on the evolutionary grazing patterns associated with pyric-herbivory. To restore the totality of native species the focus of monitoring, management and research will be sentinel ecology; sentinel plants (the first to decline at both poles of natural processes) and their dependent food web-the sentinel animals and sentinel habitats associated with these plants. The study will include the UL Bend NWR, surrounding lands on the Charles M Russell NWR, and adjacent lands held by the American Prairie foundation. This study is a continuation of 2 years prior data collection on CMR by staff from the University. Objectives: 1.) Continue data collection and monitoring of patch burned sites to measure plant response to fire and grazing disturbances over time. 2.) Monitor animal movements and measure selectivity and habitat use of past burn areas over time. 3.) Monitor post burn areas and determine amount of use compared to recently burned areas. 4.) Prepare a series of scientific peer reviewed papers that other refuges in Great Plains can use to make management recommendations concerning treatments to promote heterogeneity of habitats.
