Invasive plants represent a profound threat to native ecosystems that is expected to increase with continued land use and climate change. In the work I will present, I developed maps based on remote sensing to identify presence and absence of the invasive plant cheatgrass (Bromus tectorum) in the western U.S. I then used geographical analysis to determine the relationship between cheatgrass, land use, and climate. I will show how species distributions can be used to assess risk of invasion due to land use at the landscape scale, and to predict potential future risk of invasion under climate change scenarios at the regional scale. Applying a biogeographical approach to problems of ecosystem conservation provides a framework for land management and land use planning in light of global change. Bio: Bethany Bradley is a post-doctoral research associate in the Woodrow Wilson School at Princeton University. She received a PhD in Geological Sciences from Brown University in 2006. She is interested in the applications of remote sensing and spatial analysis for understanding and projecting terrestrial ecosystem change.
