There have been flashes of red on maples for almost 2 weeks, something that is normal. The maples that shut down photosynthesis first are the deep burgundy ones, then the odd flamer shows. It's the yellow leaf part of the forest that seems early to me.
Poor trees are probably confused with all the rain and cool weather.
I think it's going to be a long autumn, but colours may come on earlier than the last couple of years. That will make moose hunters happy. The leaves may be down by the time they are in the bush.
