Street light versus autumn

Just spotted this. Those branches of the birch tree that are illuminated by the street light have almost all their leaves left, and even though you can't really see it in the picture, there's still some green in some of them. The rest of the branches have dropped almost all their leaves. The difference is actually bigger in reality than it looks in the picture.

Just so we're on the same page -- you're saying the light is creating a microclimate of sorts, right? That's pretty neat.

Yep, that's what it looks like to me. I guess either it's messing with the photoperiod perception of the leaves, or the lamp puts out a bunch of infrared that raises the temperature locally. It's very distinct.
