Regardless, not only are the Ents immense, powerful, and vengeful, but most (and when I say most I'm being generous) of the Uruks are dead. There are less than a thousand of them left, and they don't have the ability to make more. Also, the Rohirrim (who took a blow but are still very much alive and riding) would have undoubtedly hunted down any Uruks they could find.
