Potential dispersal ranges of invasive Winter Moths in NE USA
A simple interactive map showing the potential dispersal ranges of invasive Winter Moths (Operophtera brumata) in the Northeastern United States. Winter moth observations were collected from 2020 and 2021 in northeastern states. A layer of USA Forest Types was downloaded from ESRI and Winter moth observations were extracted from the forest type cells to determine which were most at risk. After extracting, all non-occupied forest types were omitted, the remaining forests primarily included mixed hardwood forests, maple, and oak forests (shown in grey). Dispersal ranges were estimated to be ~7.4 km annually by Elkinton et al. (2015); therefore a 7.4 km buffer was created around each observation point as a potential 1-year dispersal range (shown in red) and a second buffer an additional 7.4 km from that representing a 2-year potential dispersal range (shown in orange) References Elkinton, J., Boettner, G., Liebhold, A., & Gwiazdowski, R.
