Host: Dr. Madhusudan Katti
Guests: Chris Clarke.

Topic: You may recognize this iconic tree of California and Arizona deserts the Joshua Tree. Perhaps because you’ve seen images, perhaps because you’re familiar with that rock album, or perhaps you’ve even seen these strange beautiful trees in person. But how well do you know Joshua Trees? Not as well as our guest Chris Clarke, a prolific writer and environment editor at KCET TV, who is also at work on a book about Joshua Trees.
