Maybe some of the stronger, smarter creatures survived. The Uruks do not seem to be as controlled by Sauron's will like orcs, e.g. Ugluk seems rather independent. I think they could probably survive in places like Mirkwood, and that's why Celeborn and Thranduil got together and cleansed the wood once and for all.
