You might find peak foliage to be a little later this year, by about a week. The trees are healthier, and the weather may permit them to stay greener longer. Use this map as a guide to plan your #Michigan color excursions, but check in for updates.

Most of the Upper Peninsula will peak between October 7th and October 15th this year.

This map has a two week window for each area. For a more accurate timeframe, reference the tail-end of the dates. The latter date is likely when that area will peak.

The Science Of It All

It all starts with photosynthesis. Leaves typically produce their vivid hues of green from spring through summer into early fall through the constant creation of Chlorophyll. As we all learned in 5th grade science, Chlorophyll is the key component in a plants ability to turn sunlight into glucose, which in turn feeds the trees. Many millions of these Chlorophyll cells saturate the leaves, ultimately making them appear green to the eye.

Did you know?Without the presence of Chlorophyll in the leaf, the bright golds, reds, yellows, and browns would be the natural colors seen year round.

The Changing Colors

Chlorophyll is not the only player in the fall leaf color game. Present in other leaves and trees are the compounds known as Carotenoids and Anthocyanins. As the Fall days begin to get shorter and shorter, the production of Chlorophyll slows to a hault, eventually giving way to the ‘true’ color of the leaf.

Beta-CaroteneBeta-Carotene is one of the most common carontenoids present in most leaves. Strongly absorbing blue and green light, it reflects yellow and red light from the sun, giving leaves their orange hue.

AnthocyaninsUnlike the carotenoids, anthocyanin production increases dramatically with autumn. This protects the leaf, prolonging it’s life on the tree through the Autumn season, and also provides the beautiful red color to the leaf.

FlavonolFlavonol, a part of the flavonoid protein family, is always present in leaves, and also contributes to the yellow color of egg yolks. While always present in leaves, it’s not seen until the production of Chlrophyll begins to slow.

Why do leaves fall?

The beauty of nature is sometimes found in the profound ‘intelligence’ it exudes. Perennials, which includes trees, must protect itself in order to get through the harsh, freezing temperatures of winter. If trees did not shed their leaves, their soft vegetation would certainly freeze during winter time, damaging and no doubt killing the tree.

In order to cope with the gruling winter temperatures, trees slowly close off the veins that carry water and nutrients to and from the leaves with a layer of new cells that form at the base of the leaf stem, protecting the limbs and body of the tree. Once the process of new cell creation is complete, water and nutrients no longer flow to and fro from the leaf – this enable the leaf to die and weaken at the stem, eventually falling gracefully to the ground.

What happens to the fallen leaves?

Earth, among other things, is fantastic at recycling. Whether through the water cycle, or the slow process of decomposing plants and trees back in to rich soil, the Earth wastes very little.

When leaves fall to the ground, they begin to break down and eventually create a rich humus on the forest floor that absorbs dew and rainfall. This nutrient rich ‘sponge’ acts as a continual source of nutrients and water for trees and plants, helping to promote life and plant health in the next spring season.

It is not difficult to conclude that while the falling of the leaves protects the trees through winter, it’s likely that trees would not survive as well without the rich layer of dead leaves through the warm spring and summer months. In this way, trees natural cycle provides health and sustainability for itself year after year.
