Holy cow! How Grazing Management Strategies Influence Lesser Prairie-Chicken Space Use and Demography
The lesser prairie-chicken (Tympanuchus pallidicinctus) requires large heterogeneous landscapes to fulfill its life history needs. During the past 150 years, the availability of large intact landscapes has diminished. Changes in land use have decreased the heterogeneity of vegetation composition and structure of the remaining patches. Combined, these alterations have resulted in a reduction of the species’ distribution to only 16% of its historical area. While most research has focused either on fine-scale vegetation requirements of various life history stages or broad-scale patterns of habitat selection, few have examined land management strategies that may affect lesser prairie-chicken space use and demography. We explore and summarize a body of recent work that focuses on the potential effects of domestic livestock grazing strategies designed to increase structural heterogeneity. We examine these strategies in the context of their effects on lesser prairie-chicken habitat requirements, space, and demography. Specifically, we evaluated how pyric-herbivory (i.e., patch-burn grazing) and rotational grazing systems (with extended deferment for specific pastures) could be used as management tools to meet lesser prairie-chicken habitat needs. Briefly, we found that both grazing management approaches had measurable effects on space use, and nest-site selection by females. However, demographic responses were mixed, but we are encouraged by these management strategies ability to influence space use. Perhaps more available habitat and greater vegetation heterogeneity on the landscape will create greater resiliency in the context of periodic drought and other factors affecting lesser prairie-chicken demography.
