Many people enjoy Autumn as their favorite season of the year. Temperatures are comfortable, most pesky insects are absent, animal migrations are evident, and beautiful Fall colors on the trees and shrubs are stunning. But why do these deciduous plants change color? Consider daylight, temperature, and chemistry.

Spring and summer growth and leaf production are due to photosynthesis, a process where plants use light to synthesize the cell’s chlorophyll into transforming carbon dioxide and water to carbohydrates such as sugars and starch. The cells containing chlorophyll also give the plant its green color. But there are other pigments, besides green, within the leaves all year. Xanthophyll produces orange and yellow colors, anthocyanin develops shades of red. When daylight decreases and temperatures drop in the North, the leaves stop their food-making and the green chlorophyll breaks down, leaving the other pigments to dominate the new Autumn colors.

Soon after these vivid colors appear, the tree develops special cells where leaves are attached. Those cells allow the stems to break away from the tree, due to gravity or the wind, and creates a small leaf scar. Although we may not appreciate bare limbs all winter, heavy snows collected by leaves could cause massive breaking of branches due to the additional weight.

In Southern climates, some broad-leaf trees may keep their leaves and only experience changes during wet and dry seasons. Many stay green all year. And, of course, conifers like spruce, pines and firs, retain their needle-like leaves all year.

Now picture yourself in your favorite, quiet, outdoor setting in the Fall as I read a section from the beautiful writings of Aldo Leopold, found in his book “A Sand County Almanac”. It is titled November – If I Were the Wind.

The wind that makes music in November corn is in a hurry. The stalks hum, the loose husks whisk skyward in half-playful swirls, and the wind hurries on.

In the marsh, long windy waves surge across the grassy sloughs, beat against the far willows. A tree tries to argue, bare limbs waving, but there is no detaining the wind.

On the sandbar there is only wind, and the river sliding seaward. Every wisp of grass is drawing circles on the sand. I wander over the bar to a driftwood log, where I sit and listen to the universal roar, and to the tinkle of wavelets on the shore. The river is lifeless: not a duck, heron, marsh-hawk or gull but has sought refuge from the wind.

Out of the clouds I hear a faint bark, as of a far-away dog. It is strange how the world cocks its ears at that sound, wondering. Soon it is louder: the honk of geese, invisible, but coming on.

The flock emerges from the low clouds, a tattered banner of birds, dipping and rising, blown up and blown down, blown together and blown apart, but advancing, the wind wrestling lovingly with each winnowing wing. When the flock is a blur in the far sky I hear the last honk, sounding taps for summer.

It is warm behind the driftwood now, for the wind has gone with the geese.
So would I—if I were the wind.

Most people appreciate viewing impressive forms of wildlife, such as Desert Bighorn Sheep in Zion, or Wolves and Grizzlies in Yellowstone, but they may not completely understand the quiet contributions that are being made to earth’s ecosystems every day by the small creatures around our own neighborhoods. These little ones help us in many unseen ways.

It is estimated that one third of the food that humans eat has been provided by small pollinators such as Hummingbirds, Butterflies, and Bees. Having these creatures in our own yards can produce hours of entertainment, and education, as we observe them working feverishly among our flowers, shrubs and trees.

Many citizens, and cities, are diligent in providing beautiful landscaped areas for these pollinators to gain nourishment as they work to increase the production of flowers and fruits.

A couple of quick tips as you decide to help these workaholic animals:
You can make your own hummingbird food by mixing one cup of sugar to four cups of water. Never put food coloring in hummingbird feeders. It can be harmful to them, and the red color of the feeder will automatically attract them. You should also use native, fertile plants in your landscaping design. And, unless you have a severe allergic reaction to bee stings, be assured that they are far more interested in gathering pollen than sacrificing their life to sting someone. Most people can work right alongside bees in their flower gardens. Wasps are another story.

So, as you design, or alter, your property to be more usable by pollinators and songbirds you can be rewarded by the National Wildlife Federation through their Wildlife Habitat Certification program. If you provide food, water, shelter and a place to raise young…you are eligible to have your yard certified. Remember, we’re not talking about Mountain Lions and Elk, just pollinators and songbirds. If you have a birdfeeder, birdbath, and shrubs or trees you qualify.

Nobody inspects your property. Go to their website at (www.nwf.org) and complete the simple application listed under Garden for Wildlife and, for a one-time fee of only $20, they will send you a personal certificate for your home, and a one year subscription to the National Wildlife magazine. They also have metal signs that you can post to show others that you care about wildlife. Once you see the value in this, encourage neighbors to do the same. In fact, you can have portions of your entire community certified as wildlife habitat as did Nibley City in Cache County. They were the first city in Utah to do so by certifying 100 properties, and they are ready to help others around the State to join them in this rewarding effort.

Next time you’re in the grocery store, or harvesting from your own garden, remember that a lot of that food would not exist without our diligent pollinators.

Pando is Dying

Pando, a sprawling aspen colony and the world’s largest discovered organism, is dying. On the lip of Fish Lake in Central Utah, Pando germinated from a seed the size of a grain of sand thousands of years ago. Now he sprawls over a hundred acres with approximately 47,000 trunks. The combination of the trunks and the extensive root system has Pando weighing in at around 13 million pounds. This giant male, which might be one of the oldest living organisms on the planet, is also prone to disease, wanted by humans to burn in stoves, and targeted by ungulates as a food source. And although Pando consists of literally tons of mature, geriatric trees, there aren’t many young volunteers replacing old trees that die.

Dr. Paul Rogers, a Utah State University scientist who’s trying to save Pando, explained the problem to me while we searched for new growth and deer scat on Pando. He said it would be like depending on a room filled with 90-year-olds to repopulate and save the human race—it’s possible, but not likely.

The age of the current mature trees that make up Pando is about 110-120 years. These ages are gleaned from a tree coring device called a borer. This information combined with others findings show that Pando took a turn for the worse about when Anglo-Americans showed up in central Utah. As they hunted apex predators like bears, wolves and mountain lions, populations of ungulates such as deer and elk increased. White settlers also added other ungulates—sheep, cows, and horses—to the ecosystem. Both domestic and wild ungulates feast on young, nutrient-filled Aspen trees. Which makes it so Pando can’t recolonize himself.

I asked Rogers if the reason he wanted to save Pando was because it was the superlative organism—the oldest and biggest on the globe, and he was quick to correct me. He questions the accuracy of age estimates for Pando based on current available science. And he believes there may even be larger aspen colonies, but we just haven’t found them yet. We know about Pando partially because a paved road goes right over his spine and partially because he almost touches Fish Lake. Rogers says he’s interested in saving Pando because the existence of this huge organism supports many dependent species and it likely holds lessons for sustainable cohabitation of this planet. As an afterthought he added, “If the colony dies on our watch, we’re doing something majorly wrong.”

There is hope for Pando. Aspen do two things really well: die and repopulate. In recent years, efforts have been implemented to preserve Pando. Paradoxically, some sections have been clear cut or burned to stimulate growth. Both techniques have produced positive results, but not enough. It seems the simplest solution to this problem might be the best—protect it from foraging ungulates. Eight-foot deer fences now encircle parts of Pando. Outside the fences, there are no new trees. Inside, however, green shoots can be seen pushing up from the dry ground.

The next time you take a walk in the deep woods or even a stroll through a local park, listen closely. You may hear the trees ‘whispering in the wind.’ We use this familiar phrase to describe the soothing sounds of a gentle breeze through the forest canopy; but it may delight and surprise many to know that this figure of speech is now a proven scientific fact. The trees are talking.

They don’t talk like you and I talk, of course. The spoken word is foregone by the plant kingdom, for now. Theirs is a much subtler form of communication. ‘The Wood Wide Web’, as the scientific journal Nature once dubbed it, is the woodland social network. Within it, trees send electric signals coursing through their roots in order to relay important messages to their neighbors.

Travelling at the speed of about a third of an inch every minute, these timber telegrams take quite a while to accomplish such a task; but what this system lacks in speed, it makes up for with complexity. A tree’s roots will often expand through the soil to an area twice the width of its crown, resulting in the ability of a single tree to grasp the roots of and pass messages to multiple far-away friends at once.

In undisturbed soils, these messages can be expedited symbiotically. Subsoil fungal networks, which intertwine with the roots of trees for nourishment sake, can relay messages much more quickly by connecting otherwise distant, unconnected trees to one another. This becomes quite important when the message pertains to danger: an invasion of damaging pests, for instance.

Usually, though, if a tree needs to get a warning out to its neighbors more quickly, it will do so by other means. When trees are attacked, they emit scent compounds through their leaves. These arboreal aromas can be registered by distant parts of the same tree, far-flung trees in the same grove, or, amazingly, even members of the animal kingdom, which trees will summon to their defense. Even more astonishing is that each scent is custom-catered. Trees will identify their attacker by its saliva and emit a corresponding pheromone meant to attract that attacker’s natural predators. Once they are warned of an invading pest, other trees in the grove may respond similarly.

The usefulness of a tree’s ability to communicate with its neighbors goes beyond emergency warnings or the spreading of other important information. Trees have developed a sophisticated redistribution system in which the strongest trees compensate for weaker ones by sharing their surpluses of sugar. In fact, this system is so efficient that, in the end, each individual tree is nourished at the same rate of photosynthesis. This means that every tree in a grove receives the same amount of sugar per leaf in its crown as every other tree, regardless of its own ability to photosynthesize. As it turns out, trees are highly sociable beings. They take responsibility for friends and family members and see to it that their loved ones are well cared for.

Not all groves are created equal, though. These natural behaviors can be inhibited by intensive thinning of wild groves or absent altogether in planted, monocultural forests. However, when granted enough space and time to be itself, even the most artificial forest can ‘return to its roots.’

So, whenever you find yourself following that wooded path into the forest, think of what secret messages might be coursing through the soil or floating invisibly upon the airwaves? Consider these possibilities, and your walks may now be a little more mysterious.
