Chloe Mattilio's research while a PhD candidate at the University of Wyoming was partially funded by YRLSP grant money. Her work for the YRLSP included the design and creation of two mapping applications that will be contributing to the control of leafy spurge across the entire Yampa River Basin. Chloe's remote sensing mapping application promises to accurately detect existing leafy spurge infestations using high spatial resolution, multispectral satellite imagery. Her invasive risk modelling application also facilitates monitoring potential habitats for the arrival of new leafy spurge infestations.
