Forest botanist shares favorite memories of a cool breeze, sights and smells of autumn from the Tetons

Visitors to the the North Fork Indian Creek, Palisades District can find Greene’s mountain ash (Sorbus scopulina) and thimbleberry (Rubus parviflorus) ablaze in the fall on the Caribou-Targhee National Forest as shown in this September 2005 image. (U.S. Forest Service)

The Caribou-Targhee National Forest stretches the length of the eastern edge of Idaho and includes the western backbone of the Teton Range in Wyoming.

As the days turn cooler, the perennial treat of fall’s panorama of spectacular colors offers many opportunities to enjoy the pageantry on the Nantahala and Pisgah National Forests in North Carolina.

 

 

 

 

Change in seasons brings fall color to Boise National Forest

Sometime after Labor Day when the kids go back to school, I begin to notice subtle signs of fall. This can be a welcome relief after a particularly hot summer with temperatures reaching north of 100 degrees. But the days are getting markedly shorter, and I miss the lazy summer evenings spent outdoors, listening to the sounds of nature.

 

 

 

Fall colors on Alaska’s national forests offer beautiful vistas

Black cottonwood and birch accentuate the fall season along Alpine Meadows Drive in Girdwood, Alaska near the Chugach National Forest.

Ever think about fall colors in Alaska? Now’s the time with autumn foliage colors peaking from late August to early October in Alaska’s Tongass and Chugach National Forests. However, since the national forests are in the temperate part of Alaska and are dominated by coniferous trees, the colors are generally not as spectacular as the brilliant colors of interior Alaskan trees and shrubs.

 

 

 

Kids and kids at heart can enjoy making and sharing a digital leaf press

Here’s a leaf you may find on your adventure. This beautiful collection of leaves on the branch of a blackjack oak (Quercus marilandica) shows how the red coloration is revealed as the sugars of the green chlorophyll is absorbed into the tree as it prepares for the cold of winter.

This time of year brings back fond childhood memories. Fall’s increasing chill and leaf-covered ground take me back to elementary school, where nature and the changing seasons served as learning material. A favorite lesson I learned was how to create a book of pressed leaves.

 

 

 

 

Share the joy of a botanist’s annual pilgrimage to the Darlingtonia Fens of the eastern Klamath Mountains

Sedges line the clear headwaters of Deadfall Creek in the Eddys, high peaks in the Eastern Klamath Ranges of northwestern California.

I dreaded October as a child. Growing up on the Oregon coast, October promised rain and more rain—rain on my birthday, rain on Halloween, rainy rain rain.

What a difference 300 miles and the rain shadow of a mountain range makes! October here in far northern California on the Shasta-Trinity National Forest brings me nothing but pleasure.

 

 

Forest Service wants you to get in where you fit in!

A layer of green, yellow and red leaves surround a road that winds past the birch and Sawtooth Mountains on the Superior National Forest.

Every fall, nature puts on a dazzling show across America’s great outdoors for all of us to see. Whether you’re an adventurist or someone who just likes a good road trip, national forests are the places to be this time of year.

 



Fall colors the muskeg on Alaska’s Tongass National Forest

Muskegs, a colloquial term for peat bogs, blanket 10 percent of the Tongass National Forest. These wetlands range in size from a few square feet to many acres. Over the ages, muskegs formed as Sphagnum mosses, rushes and sedges grew and built up spongy carpets in these very wet, almost treeless areas.

 

 

 

 

Maple syrup flow threatened

Forest Service research indicates that climate change will affect habitat suitability for maple trees, threatening the multimillion dollar maple syrup industry.

 

 

 

 

Consider the alpine larch in the northern Rocky Mountains

Subalpine larch is one of the last trees to be found before entering an alpine ecosystem. This landscape is dominated by subalpine larch on Temple Ridge with Prusik Peak in the background on the Okanogan-Wenatchee National Forest.

Do you think that all evergreen conifers are always evergreen? In general, that’s true but the forested landscapes of the northern Rocky Mountains offer an amazing colorful exception to this each fall with the spectacular shows of the Alpine larch (Larix lyallii).

 

 

 

Fall wildflowers are part of the fall colors parade in the east and south-central United States

Amongst the falling leaves, you might discover the frost flowers of dittany (Cunila origanoides). Its former light blue flowers have come and gone, its seed cast to the wind, but from the base of their stems you may be lucky enough to see what looks like curling ribbons of ice, one last gem of their blooming glory, a frost flower.

Fall is a wonderful time to find an amazing array of wildflowers on your national forests and grasslands. But before you venture out, take a moment for a sneak preview on the U.S. Forest Service’s Fall Colors 2013 web site for a few ideas to plan your visit.
