Here’s what’s happening in Chicago nature, right now!
Enjoy the Fall Colors: The Prairies Are Colorful. The Woodlands Are In Various States.
We’re now four weeks into autumn and the transition of tree color is moving very slowly. While the prairies are donning their fall colors, the tree foliage is either still green, transforming into a faded hue, or turning brown and dropping off. It all depends on the preserve. Just get out there in the fresh autumn air and enjoy yourself. The prairies are the first habitats to display autumn color in the foliage. It is a beautiful mosaic of colors and textures. In one small patch of prairie, it’s common to see more color than any autumn woodland in the region: oranges, golds, reds, maroons, cyans, browns, and tans. Visit the prairie to experience towering waves of red-stemmed grasses and tawny, fluffy spikes of gayfeather that glow in the sunlight. Here’s a list of prairies (and savannas) that are looking really nice and that you can visit throughout the fall season:Prairies to visit this fall:

Fall Colors to Look Forward to:

At Spears Woods, with the warm evening light falling on this October prairie, the tubular tops of blazing star burned with a golden glow; but not two months earlier, they blazed with purple passion. Autumn transformed the cylindrical inflorescence of hundreds of feathery purple flowers into a column of invisible seeds—invisible because what we see is not the seed but the achene, a dry fruit with a single seed hidden inside. On this plant, also known as gayfeather, each achene, by design, forms a downy tan plume that takes to the air to be scattered by the wind.*

In the fall at Illinois Beach Nature Preserve, don’t just stare up at the trees. Look down. There’s a bounty of color at your feet. Here, a black oak leaf landed amidst a bed of pasture rose with leaves more vibrant than any tree in this savanna.*

In the fall at Black Partridge Woods, I head to the high vantage point of these bluffs to immerse myself in the intoxicating colors and textures of the tiered foliage. Down below, the creek bed is dry. But when the flow returns, fallen leaves will ride the colorful currents that reflect the radiant dome.*

Compared to the golden maples of autumn, oaks can be a bit understated. Here at Bluff Spring Fen, this bur oak, when placed in the spotlight, certainly puts on a show.*

As you hike the boardwalk and the narrow sections of the Cowles Bog Trail, you may find yourself glancing down to watch your step. But in the fall, remember to raise your eyes to view the scenery in the skies.*
