This graphic by Kevin Hall displays the quantity of ash by county across the northeastern and north central United States. With a quick glance, the readers establish a high concentration of ash in Minnesota, New York, and Maine.
While the graphic makes it appear Minnesota has the highest concentration, this is only because of the larger counties (St. Louis County is one of the largest in the nation). Maine has the largest concentration of ash trees in the United States.
The small grey lines show the general quarantine of the Twin Cities, which is now a general infestestion.
