Correct, this is a photo taken in Nebraska in a suburban less than quarter acre backyard. I have a call out to the extension office to verify the range of poison sumac hasn't migrated to my area.
Extension returned call quickly. There are no reports of poison sumac in the state. They suggest fighting the battle with Triclopyr to stop the spread of rhizomes. I will do that (not a chemical person unless there is a serious problem.) Cut stem to 4 inches and immediately brush chemical on open wound.
