There is the old forest outside of Hobbiton. I'm afraid I don't have a copy of FotR with me to look up the name. But it was "alive" in the sentient sense enough for even the hobbits to notice. It clearly remembered what had happened in the past as well, when the hobbits drove it back.
Also Caradhras at least seemed actively malevelent. Forgive me if I mixed up any of that info, it's been too long since I last read the books. I've always taken Legolas literally on that part. I hadn't realized it could be thought of another way. Interesting.
