Ah, autumn. Time of crisp air, changing colors, and falling leaves... (I snapped this photo today in Rock Creek Park). What a great time to think about volunteering to help preserve and protect the trees you love!
A few organizations that I like are the Audubon Naturalist Society (with a sanctuary just a short bike ride from from my home) and the Sierra Club (with whom I volunteered in Vieques, Puerto Rico a few years ago).
What are your favorite tree-hugging charities?
