The gray fox is Iowa’s other fox, a grizzled, tree-climbing animal that favors rough, wooded country over the open farmland the red fox handles so well. Iowa’s documented picture of it is thin: 12 records since 2000, and the most recent dates to January 2021. NatureServe ranks it vulnerable in the state, so every confirmed report carries real weight.

What geography the records do show points northeast. Allamakee County, in the rugged bluff country above the Mississippi River, holds more reports than anywhere else, with Effigy Mounds National Monument and Yellow River State Forest sitting in exactly the kind of steep, timbered terrain this fox prefers. A lighter scatter reaches Johnson, Cedar, and Muscatine counties in the east, plus a few western outliers along the Missouri side.

The timing is striking: nine of the twelve reports fall in January or December, the leafless months when a fox is easiest to spot and tracks read clearly in snow. That says more about when people notice a gray fox than when it’s active, since the species doesn’t hibernate. The state’s record is sparse enough that no county can fairly be called a hotspot; it can only be called better searched.
