Extinction of Survival?

Some people complain that the NEWS only reports bad things, and that can be depressing. But maybe that is the way we can learn how to improve things. If all we ever heard was that everything was wonderful, even though it truly wasn’t, how would we feel if we accidentally stumbled across a negative situation? Let’s consider the present global status of the wildlife with which we share this planet.

One of the pleasures of hiking in scenic vistas, such as our forests or National Parks, is to see the wildlife that call those places home. People want to see bears or wolves in Yellowstone. They are thrilled when they see Desert Bighorn Sheep in Arches or Zion. But the latest comprehensive report on biodiversity by the United Nations revealed some startling results. The report included over 1,000 pages compiled by more than 450 researchers who analyzed 15,000 scientific and government reports. And this summary had to be approved by representatives of all 109 nations.

The message is that nature is being threatened more now than any other time in human history. Literally, a million species of plants and animals are facing serious threats to their survival. And this is due to several harmful actions: Invasive species that crowd out native wildlife from their home habitats; the pollution of water and land by the dumping or runoff of toxic materials; overfishing the oceans; and permitting the continual burning of fossil fuels which alter the climate for some wild species. And, as a result of increasing human populations, many forests and grasslands are converted into farmland, cities, or business ventures. That reduction in the number of large plants and trees affects the Earth’s ability to reduce heat-trapping carbon dioxide.

Currently, over 1,200 mammal species, 1,500 bird species, and 2,300 fish species are threatened, endangered or extinct in the wild.

This indeed sounds dismal, but if we consider it as a warning there is still time left to alter this downward spiral. What can we do? Simple tasks, really: Replace lawns by planting trees, shrubs and flowers native to your area. This provides habitat as well as food for pollinators. Avoid using harmful pesticides and herbicides which can collect and wash down into streams and rivers, which then pollute that water as well as the ocean. Respect the privacy needed by wildlife by observing them from a distance. Never poach any species. Place birdfeeders and/or birdhouses in your area. Consider renewable energy sources for your home and community. Don’t allow your vehicle engines to idle. And encourage your community to preserve open, green spaces when new developments are proposed.

Life is easier if we decide to let others do the work that will benefit us all. But if everyone made some small improvements in their lifestyle we might be able to avoid future dismal reports.

In the book, The Hidden Life of Trees, Forester-Scientist Peter Wohlleben reveals some amazing characteristics that are generally unknown by the humans casually walking by the trees in a forest. This is part two highlighting this book and I highly recommend you consider searching for it in bookstores or online.

Wohlleben states that trees communicate with each other by using scents. It seems that various trees can release toxins into their leaves when being eaten by herbivores looking for a meal. But these trees also warned nearby relatives of the same species by releasing gases as a signal they were being invaded. Those neighboring trees quickly pumped those same toxins into their leaves to prevent an oncoming attack.

It was also learned that sometimes trees can identify the insects that are eating their leaves by tasting the saliva being secreted by those attackers. The trees can then release scent-based pheromones to warn neighbors that they are being assaulted, but also summon beneficial insects which then prey upon those original assailants. These new findings imply that trees can determine certain scents, and if they can interpret different insect saliva they must also have a sense of taste.

These warnings to neighboring trees aren’t always carried through the air. Consider days when there is no wind. They can also be sent using chemical signals sent through the fungi around their root tips. Serious problems can occur when trees lose these skills as well as their ability to defend themselves. This is one important reason to maintain undisturbed sections of old-growth forests. Wohlleben also cites a study in Australia when it was observed that the roots of grain seedlings oriented their root tips toward the origin of sound frequencies of 220 hertz. Can trees taste, smell, respond to electrical signals, and hear sounds? It seems incredible, but how much do we really know about trees?

Consider the many benefits trees provide for humanity and other life forms: Of course they can be used for building or fuel, but they can raise property values by as much as 15%; they take in Carbon Dioxide for growth and release Oxygen; they help moderate the climate; they purify the air of toxic substances; they produce fruit and nuts; they provide habitat for insect-eating birds; they provide cooling summer shade and reduce heat-islands in urban settings; they reduce noise levels and light pollution for scenic night skies; they provide soil stability to reduce erosion; and they provide scenic green-screens for privacy. Research has also shown that urban tree areas have lower crime rates, and hospitals report that recovery from physical or mental issues are improved and hastened by having trees in their landscape.

There is much more to learn from the book, The Hidden Life of Trees. And Fall and Spring are the ideal times to plant these quiet, scenic wonders.

Occasionally, we run across a piece of art, music, or literature that we want to share with others. That isn’t always the case with beautiful scenery. Sometimes we want to keep that place as a private haven of serenity. And for good reasons.

Today, I will describe something that has opened my eyes to a world that few people know about. I refer to the research revealed in a book titled “The Hidden Life of Trees”, an International Bestseller, by Peter Wohlleben. He is a Forester-Scientist in Germany who has connected with others in his profession for over 20 years to reveal things about trees that most of us would never have expected. Here is Part One:

You may recall the basic photosynthesis functions related to the lives of trees. Roots carry water and minerals from the soil through the xylem tissues of the trunk up to the leaves. The leaves, with the help of chlorophyll, capture Sunlight Energy and Carbon Dioxide from the atmosphere, and release Oxygen into the air. Sugars are also produced and go downward through the phloem tissues to the trunk and roots. The way I remembered this process in biology classes was that the X in xylem has its upper lines reaching skyward, and things Flow downhill.

The scientists knew that most individual trees of the same species growing in the same forest stand are connected to each other through their root systems. Nutrient exchanges revealed that forests are superorganisms with interconnections much like ant colonies. This indicated a sort of social system where trees will share food with their own species and sometimes even nourish their competitors. Why are they considered social beings? Because there are advantages in working together.

It seems that single trees, much like hermits, have greater difficulties in having a successful life. It can be done, but it’s tough. A single tree cannot establish a consistent local climate and must battle weather conditions. Whereas a forest often creates an ecosystem that can somewhat modify extreme temperatures, store a lot of water, and generate a lot of humidity. These kind of living conditions can provide trees with great longevity. But for this success the forest must remain intact. Tree removal, or fatalities, would result in gaps in the tree canopy, which would then allow for greater deviations in temperatures, make trees more vulnerable to uprooting from storms, and allow greater summer heat to dry out the forest floor. Every tree would then suffer.

Wohlleben continues to say that social connections can also be seen in the forest canopy. Most trees grow their branches out until they encounter the branch tips of a neighboring tree of the same height. Growth usually stops there because the air and better light in that space is already being used, and the trees don’t want to take anything away from each other.

But, as a rule, those planted in forests can live much like single wild trees and react by suffering from isolation. And remember that he is writing about forests, not single trees planted in a well-kept yard or for landscaping.

I’ll continue referencing “The Hidden Life of Trees” in future shows and talk about Why Forests are Green; How they act as a Water Pump, and are Carbon Dioxide Vacuums.

If you have ever been to a museum you have witnessed historical items that may be hundreds, or thousands of years old. When we look outdoors at the natural geology of our planet earth, we may be witnessing things that are hundreds of thousands, or even millions of years old.

I realize that there are some people who disagree with the aging with which some scientists label various mountains and canyons, so let’s just settle on the fact that some of these places are very, very old.

There is only one place in the United States where a person can put his feet and hands in four different States at the same time, and that place is called The Four Corners. The story behind this incredible area deals with the formation of what is known as the Colorado Plateau. This area covers 130,000 square miles in Utah, Colorado, New Mexico, and Arizona. If you have ever been to any of Utah’s Mighty Five National Parks you are on the Colorado Plateau, but it’s much more than that. There are 3 national recreation areas, 10 national parks, and 16 national monuments all included in that amazing geologic formation.

Scientists say that millions of years ago tropical seas covered the Plateau region where layers of limestone, sandstone, silt and shale were continually deposited. When upheavals began to lift the plateau, and mountain-building events occurred, volcanic eruptions also accented the western area. Eras of various rivers, lakes, and inland seas continued to leave sediment deposits known as the Chinle, Moenave and Kayenta layers. Later, a huge desert formed the Navajo, Temple-Cap and Carmel formations.

Tectonic activity began to uplift the Plateau nearly two miles high and slightly tilt it to the west. Rivers and streams responded with increased downcutting and erosion which revealed scenic wonders from narrow slot-canyons to huge cuts in the earth’s surface. Perhaps you have heard the term “Grand Staircase” which describes the descent in altitude from Bryce Canyon down to Zion Canyon and further down to the Grand Canyon in Arizona. About ninety percent of the area is drained by just a few rivers including the Colorado, Green, San Juan, Little Colorado and the Rio Grand.

Why emphasize the geology? Besides climate, think how the soil and rock formations determine water retention and flow directions. How water and soil then determines the plant life in an area. And finally, how all three of those components determine what wildlife will exist in that same area.

So the next time you visit Utah’s Mighty Five: Arches, Bryce Canyon. Canyonlands, Capitol Reef, or Zion Canyon, try to picture yourself atop a huge natural table-top with incomparable scenery.
