After the fall: Some leaf science

By Steve Roark

Tree leaves are most appreciated when they go through their fall color blitz that we enjoy every year. But they should also be appreciated for all they do throughout the year, including creating food and fiber through the miracle of photosynthesis, and through their death their provision of a raw materials needed for next year’s growth of new leaves. Going from dead leaves to nutrients that can be taken up by a tree requires an amazing recycling system.

A Deer’s Social Calendar

By Steve Roark

Socially, male and female white-tailed deer live separate lives except for a brief mating period in the fall. Bucks tend to hang in small groups amongst themselves, and does hang out with other females, along with their yearlings and fawns.

The Blue Skies of Autumn

I look forward to the skies of September and October and their intense blue every year. Autumn skies typically have a lot of big puffy cumulus clouds as well, highlighting the blue even more. Scanning the sky from overhead to the horizon will show that the brilliant blue overhead fades to a lighter blue near the horizon. Let us delve into some sky science and see what’s going on.

Roadkill

Animals killed by automobiles are a common in rural areas. Skunk, ‘possum, turtles, and more recently, armadillos, who have managed to work their way east to our area. I recently saw a squashed aardvark in front of the McDonalds in Tazewell. Skunks are so brazen due to their very effective odoriferous defense mechanism, that they meet their end thinking ...

Fall Colors and the Weather

The autumn coloration of trees is always looked forward to with anticipation, and is beginning to show in the higher elevations. The presence of a large number of tree species having brilliant fall foliage is more unusual than you think, as the only other places in the world with a similar abundance of foliage colorations are northern China, Korea, and Japan.

The hills are alive with the sound of nature

When appreciating the natural world, getting out and seeing it is mostly how it’s done. We go on vacations or road trips to see beautiful things like forests, mountains, rivers, oceans and canyons.
This makes sense, since we are wired to perceive the world mostly through the sense of sight. Thirty percent of the neurons in our brain’s cortex is devoted to vision. For comparison, eight percent is used for smell, and only two percent is used for hearing.

Katydids

It’s hard to spot Katydids because they are so well camouflaged. But anyone who sits on their porch on a late summer’s night has enjoyed hearing their “katy did….katy didn’t” song, along with their chirping cousin, the cricket.

Fall Tree Planting

While spring is the traditional season to plant trees and shrubs, fall may be better. The soil is still fairly warm on into December, and it gives the tree a chance to rest and get well settled into the soil before the spring growth spurt. The following are a few guidelines on choosing and planting trees.

Forestry is a big deal

Many consider forestry to only mean growing trees to cut for lumber, and in the old days that was true. But the forest is much more than a place to produce wood fiber and it has multiple uses it can be managed for. Many of these uses can be managed simultaneously with proper planning.
Here is a list of the major uses.

The House That Saved the South

Let me warn you that this story is not for the squeamish. Way back in 1908 the millionaire John D Rockefeller wanted to make still more money, but most of his markets were saturated, so he began looking at the southern United States as an untapped marketplace. But there was a problem…the South’s economy was lousy. The people were illiterate, dirt poor, and were perceived as lazy. Farms weren’t fully operational, and the economic engine seemed to be turned off.
