Need Help Finding Books for a Unit on Ecosystems

I am doing a series of annotations of excellent books. I need at least 20 titles in the following 'genres': poetry/song, picture books, historical fiction/biography, traditional (folklore/myth) literature, & non-fiction.

Non-fiction and picture books were super-easy, of course. I am finding some naturalists' biographies to use. Poetry is harder - I am not a follower of the genre. Traditional literature is tricky as well. And I have just about given up on historical fiction.

The idea is that I find 20+ books, ideally 4 per genre listed above. I annotate the books (the bulk of the paper) and come up with 10 activities (briefly described) to do in a unit. This is a literature class, so the books have to be primo.

For bios I have: Sylvia Earle & Audubon. I am planning to find a focused bio on Thoreau (not about civil disobedience, but about his nature treks). I think I'll find a bio on Rachel Carson. These people study natural environments/ecosystems, document them, find problems and try to resolve them (not all at once!).

I thought the traditional texts could be about how people viewed ecosystems in the past. As in: all the sea creatures and water on earth erupted from a giant pumpkin (Puerto Rico). Sort of creation myths, but more focused on nature rather than humans.

The biggest problem I am having is getting diversity. There are very few ecologists/environmentalists of color. I was going to try to focus on Americans, but I may have to suck it up and move out to other countries. I even visited a website for a group called african-americans environmentalists (or something close to that). While it was an interesting site, I couldn't find what I needed.

I need: more diversity in my scientists or protagonists and more traditional tales. I'd love it if someone could recommend a historical fiction title.

Thanks!
