Good title for a western manga?

I know, I'm posting this on random and not manga, but normally the answers come more quickly here than anywhere else. I think anyone who's asked a question here will understand.

Anyway, I'm creating a slightly more western-style manga (as I'm from the US), and I can't think of a title. It's about a teenage girl who can talk to animals. Her name is Yoshikawa Natsumi, and she travels with three other people her age. Since she talks to animals, she's constantly visiting forests, caves, etc....

The antagonist is a person known only as Noboru, and his ultimate plot is to tear down all animal habitats and replace each one with something for him (a castle, a mansion, skyscrapers, etc.). Natsumi's goal is to protect the heart of all animal habitats, a gigantic forest (I might use the title for the name of the habitat, depending on the suggestions), while fighting to restore the rest of the habitats as well.

I may or may not use any of these suggestions, and might post a promo chapter on Fanpop eventually. Any ideas?
