Measure effects of cattle space use intensity on vegetative structure and composition within multiple grazing systems
Assess effects of cattle space use and subsequent vegetation response on lesser prairie-chicken space-use and home ranges during key life stages
Investigate characteristics of female lesser prairie-chicken dispersal routes to determine what features affect dispersal at the landscape scale
Progress and Results:
Historically, Great Plains grasslands were shaped by a constant flux of disturbances and stochastic events such as fire, rainfall, and grazing by large herbivores. This natural continuum created a patchwork of habitat types that are used by grassland obligate species of conservation concern, such as the lesser prairie-chicken. European expansion has permanently changed and fragmented these landscapes, but modern land management strategies can mimic historical patterns to conserve habitat for lesser prairie-chickens. This project investigates the influence that landscape management and configuration have on lesser prairie-chicken movement patterns. We will determine how two contemporary management regimes, patch-burn grazing and rotational grazing, influence the spatial arrangement of GPS-collared cattle within pastures. We will then determine how GPS-marked female lesser prairie-chickens use different areas of cattle grazing intensity during different life stages, such as nesting, brooding, and non-breeding. We will also assess female lesser prairie-chicken movement at landscape scales, to determine how landscape configuration and anthropogenic features influence female dispersal. This will inform management aimed at increasing genetic connectivity between lesser prairie-chicken subpopulations.
We found that patch-burn grazed pastures have greater fob and bare ground cover than rotationally grazed pastures. Additionally, patch-burn grazed treatments have greater variation in vegetative structure and composition across gradients of high, moderate, and low cattle grazing intensity within pastures. This increased variation could correspond to a greater variety of habitat types used by lesser prairie-chickens during different seasons.
