John Swales

Today, we'll  focuses on butterfly species in Washtenaw County. There are more than you might think, and these delicate creatures can be a good indicator as to the health of the local environment.

This week's guest is John Swales,  the North American Butterfly Association  population survey coordinator for Washtenaw County and U-M Professor Emeritus of Linguistics. We'll be discussing his long-standing participation with the NABA butterfly counts, and what the surveys tell us about the status of different butterfly species in Washtenaw County.
