Exotic/Invasive Species Management

    Back to Research   


Since uncovering the link between feral pigs and the decline in foxes, I’ve conducted additional research into how invasive species impact our natural treasures. In conjunction with Dr. Mark Andersen and the USGS Center for Analysis of Spatial Ecology we examined how both exotic vertebrates and plants impacted Big Bend National Park.
