I'm not sure if this article was posted to the list last year, but I could
not see it in the archives. This fascinating 3-part series captures the
complexities of ecosystems and the importance of seed collection.
The Iconic, Vanishing Joshua Tree: Species Collapse - Evolution, climate

*Editor's Note: This is Part 1 of a three-part series about the precarious
survival of the Southwest's iconic Joshua trees, which are threatened by
climate change and urban sprawl. **Click here for Part 2

and urban sprawl is challenging the survival of this idiosyncratic species.
