Ep. 73- On Milkweeds and Monarchs: The Search for a Smoking Gun

Monarchs have become the poster child for protecting, conserving, and restoring native flora. Over the last decade monarchs have witnessed massive declines in their numbers. This has led to a lot of speculation as to what might be causing such declines. It seems like a simple black and white issue, monarchs need milkweed and we have plowed over most of the milkweed on this continent. As straight forward as this may seem, students of ecology will note that nothing in nature is that simple. Monarch and milkweed conservation is a complex issue with a lot of causes and that is where people like Dr. Greg Spyreas come in. Using large scale datasets, Greg and his colleagues are painting a more nuanced picture of milkweed and monarch decline. It is an interesting story that you don't want to miss. This episode was produced in part by Gregory, Mark, and Bryan. See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
