More than a century of fire suppression in the Great Plains has altered fire regimes and led to a conversion of grasslands to woodlands, thereby resulting in loss of habitat for grassland-obligate fauna, particularly prairie-chickens (Tympanuchus spp). An additional consequence of fire regime changes has been an increase in the occurrence of large, catastrophic wildfires in the southern Great Plains over the past 30 years. While prescribed fire has been proposed as a fuels reduction treatment, fire alone may have limited utility in the region and would likely require annual treatment, resulting in further loss of biodiversity. Pyric herbivory, which allows for an interaction between fire and grazing, has been implemented in some parts of the region and resulted in increased biodiversity and livestock production. We sought to evaluate the potential for pyric herbivory to simultaneously benefit fuels reduction and prairie-chicken habitat conservation objectives. We established a large-scale experiment to compare prescribed fire treatments without grazing to those where grazing is allowed to interact through pyric herbivory across four sites throughout the southern Great Plains. We used fuels data collected in the field to customize fuel models in BehavePlus 5.0 and simulated fire behavior characteristics. We also collected vegetation community data for comparison to known prairie-chicken habitat requirements. We found that time since fire is the main driver of biomass accumulation, and the fire-grazing interaction can mediate the rate of accumulation. We also found differences between treatments in vegetation community characteristics key to prairie-chicken habitat. Our data indicate that pyric herbivory offers extended fuels reduction benefits compared to fire-only treatments. Pyric herbivory also maintains vegetative community structure and composition suitable to the various life stages of prairie-chickens. We suggest the implementation of pyric herbivory as a fuels management practice in the southern Great Plains, especially in areas where conservation of biodiversity is also a concern.
