Description
he primary thing that triggers the changing of colors in leaves is the length of day. However, moisture and temperature play a role as well. For instance, an extreme drought in the summer can delay somewhat the changing of the colors in fall. Why this is the case is not wholly understood, but it is possibly from the tree not being able to make as much food to store up for the winter, in the case of the drought, so it might be trying to push the envelope a little in terms of making food for a couple more weeks before needing to shed the leaves.
Temperature also plays a part in the ultimate vividness of the color. However, as far as the timing goes, seems to play a very small role given that trees of the same species at very high elevations, where it is colder, will have their leaves change color at nearly the exact same time as those of the same species at lower elevations on the same latitude line.
Primarily though, as the length of day shortens, at a certain point which varies by species, some mechanism in the tree will trigger it to begin the process of closing up the veins to the leaves and eventually shedding them, lest they freeze while the veins are still open which can potentially harm the tree.
I had a hard time with this image. The sky was very pink when I captured this early in the morning. However it looked fake, so I whitened it up. Not sure I like this any better, but I love the fog and how it transforms the lake!

Excellent capture and colors, Elizabeth. I'm a fan of fog, probably because we don't get it often around here. I love the mood of this beauty and the fall colors behind the fog take it over the top. f/l

I just love it too. We don't get it a whole let either, mainly in fall. Thanks Karen!
