Abstract or Description

We created three maps using Arc GIS and projected them using the USA Contiguous Albers Equal Area Conic projected coordinate system. The first depicts the spread of the hemlock woolly adelgid since its introduction to the United States. The second shows areas that are most at risk to future spread according to a model we created. The final map serves to test our model for predicting future spread.
