Every fact cited
Lawrence County is not on South Dakota’s current EAB quarantine list. For Spearfish, home to Black Hills State University and set at the mouth of Spearfish Canyon, that means monitoring rather than urgency — but the Black Hills region’s mix of native and ornamental ash still makes it worth knowing the signs ahead of time rather than after the fact.
