Western PA Phenology

“Phenology” is the study of the times when natural phenomena recur.  Chuck Tague and I built this list in 2008-2009, including links to his online material. Chuck’s website was discontinued a few years after he passed away in June 2016. His links are broken now; it is taking me a while to remove them.

This phenology was written in 2008-2009 before climate change moved some events as much two weeks earlier. What changes do you see? Leave a comment.
