Spotted Lanternfly Spread in the US

This project was my final project in my introduction to GIS course. We were tasked with making a poster for a spatial analysis that we designed and executed ourselves on a topic of our interest. I chose to look into the potential spread of the invasive Spotted Lanternfly (SLF) in the US under current climate conditions. I used point data from EDDMaps to find out where SLF are currently found. I downloaded a csv file of this data and cleaned it up for easier use before importing it to ArcGIS Pro and projecting the points from coordinate values. I used data from WorldClim to assign a range of temperature and precipitation values to the current location of SLF. I then used this climate data to predict where the species might be able to move based on only the temperature range, only the precipitation range, and both combined. My conclussion was that there is potential for expansion of the SLF habitat towards the western US under the current climate conditions.
