Things are about to change. I typically walk or take a run through Reflection Riding daily and have noticed the forest seems to be in a transitional phase. There seems to be a lull hanging over the forest as if the trees have already acknowledged that the days are getting shorter and they are within just a few weeks from slipping into the splendor of fall. My favorite time of the year.
But summer hangs on. As Joyce Stanbery mentioned recently in her blog “Woods and Wildflowers” the Pilewort and Asters are still blooming and the humming birds frequent the Jewelweed in front of the caretaker’s cabin. But not for long. By mid to late October it all changes.
From Reflection Riding you will see a wave of colors drift down the slopes of Lookout Mountain until the whole valley shimmers in hues of gold, red, pink and orange. So why does this cycle occur? Keep in mind I’m just a casual observer but here is a brief interpretation of what I’ve read.
We’ve all heard of chlorophyll. Well apparently it not only assists the tree with photosynthesis but it also masks the true pigment of the leaf during the summer months and is the reason for their green color. Carotenoids and Anthocyanins, types of organelles in the plant cell, determines the color shift in the fall.
As the days shorten, the trees slowly stop producing chlorophyll to conserve energy for the winter. During the fall months, the golden yellow or copper colors are the result of carotenoid pigments in the leaves. Anthocyanin pigments are responsible for the pink, red, and purple leaves. These colors favor warm sunny days followed by cool nights. A cold snap or cloudy days near the peak of season reduces their brilliance causing them to turn brown and fall more quickly.
In my opinion, fall is one of Mother Nature’s premier events. And if you have a yard to rake, just consider the extra work the price for admission.
