So have the trees, apparently.
Don't get me wrong... most of the trees are as green as ever. Still, just a few trees... trees in unusually wet or dry environments, or trees that are otherwise stressed by their environment... are starting to show a few vivid colorful leaves.
I've only been through three Vermont autumns, so I often find myself wondering when and how each tree species will respond to the changing weather. It's been more than just a casual question, lately, because I've been mapping a lot of natural communities at work, and in many cases vivid fall foliage is available in photos! I see a rainbow of colors across the landscape, but often wonder what exactly I am looking at.

The red trees above are probably red maples; the yellow ones perhaps black ash. It's hard to say though (Which ash species again was it that turns purple? White ash?).
To answer these questions, I started a fun citizen science project on iNaturalist.
