Pothole Ecosystems
Potholes on the Colorado Plateau are depressions primarily in the sandstone, unassociated with any drainage, that are home to ephemeral pools of water. These potholes provide shelter for life in a hostile environment and many species have survived to the modern day only because these rain filled pools are available. We speak with biologist/ecologist Tim Graham about the types of organisms that have adapted to live in these ephemeral pools and why humans should try to avoid these fragile ecosystems.
