ENO Environment Online is a global network for sustainable development and peace on the planet. Schools around the world are studying environmental issues, share knowledge and learning outcomes and make concrete agreements to achieve balance with the planet. It is coordinated by the ENO based in Joensuu, Finland. It has numerous partner organizations and networks, including the United Nations Environment Programme.

Why Trees Are Valuable and Important




TREES...


Trees are important, valuable and necessary to our very existence. It's not too hard to believe that, without trees we humans would not exist on this beautiful planet. In fact, some claim can be made that our mother's and father's ancestors climbed trees - another debate for another site.
We prefer planting Mangroves...

Still, trees are essential to life as we know it and are the ground troops on an environmental frontline. Our existing forest and the trees we plant work in tandem to make a better world.


1. Trees Produce Oxygen
Let's face it, we could not exist as we do if there were no trees. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year. What many people don't realize is the forest also acts as a giant filter that cleans the air we breath.


2. Trees Clean the Soil
The term phytoremediation is a fancy word for the absorption of dangerous chemicals and other pollutants that have entered the soil. Trees can either store harmful pollutants or actually change the pollutant into less harmful forms. Trees filter sewage and farm chemicals, reduce the effects of animal wastes, clean roadside spills and clean water runoff into streams.


3. Trees Control Noise Pollution
Trees muffle urban noise almost as effectively as stone walls. Trees, planted at strategic points in a neighborhood or around your house, can abate major noises from freeways and airports.


4. Trees Slow Storm Water Runoff
Flash flooding can be dramatically reduced by a forest or by planting trees. One Colorado blue spruce, either planted or growing wild, can intercept more than 1000 gallons of water annually when fully grown. Underground water-holding aquifers are recharged with this slowing down of water runoff.


5. Trees Are Carbon Sinks
To produce its food, a tree absorbs and locks away carbon dioxide in the wood, roots and leaves. Carbon dioxide is a global warming suspect. A forest is a carbon storage area or a "sink" that can lock up as much carbon as it produces. This locking-up process "stores" carbon as wood and not as an available "greenhouse" gas.


6. Trees Clean the Air
Trees help cleanse the air by intercepting airborne particles, reducing heat, and absorbing such pollutants as carbon monoxide, sulfur dioxide, and nitrogen dioxide. Trees remove this air pollution by lowering air temperature, through respiration, and by retaining particulates.


7. Trees Shade and Cool
Shade resulting in cooling is what a tree is best known for. Shade from trees reduces the need for air conditioning in summer. In winter, trees break the force of winter winds, lowering heating costs. Studies have shown that parts of cities without cooling shade from trees can literally be "heat islands" with temperatures as much as 12 degrees Fahrenheit higher than surrounding areas.

8. Trees Act as Windbreaks
During windy and cold seasons, trees located on the windward side act as windbreaks. A windbreak can lower home heating bills up to 30% and have a significant effect on reducing snow drifts. A reduction in wind can also reduce the drying effect on soil and vegetation behind the windbreak and help keep precious topsoil in place.


9. Trees Fight Soil Erosion
Erosion control has always started with tree and grass planting projects. Tree roots bind the soil and their leaves break the force of wind and rain on soil. Trees fight soil erosion, conserve rainwater and reduce water runoff and sediment deposit after storms.


10. Trees Increase Property Values
Real estate values increase when trees beautify a property or neighborhood. Trees can increase the property value of your home by 15% or more.

The Most Popular Trees


We've reviewed the popular literature for you, polled my About Forestry forum and the Internet for the most popular trees and compiled these frequently requested trees to use as a starting place. By further studying the commercial appeal of each of these individual species and taking into account horticulturists' praise I selected my ten best.


One other criterion we set is, the tree has to be native to North America with large ranges and do well in and around those ranges. Exotics tend to have two-edged problems: they either express later health problems (insects, disease, brittle) or quickly become a green scourge that threatens native trees and plants. Sometimes they have both problems. These trees become very large and needs a large yard or landscape.

Our Best Tree Picks


All of the trees selected here have been screened to make a great yard tree within the limits of their potential habit and growth constraints. we think you will be pleased and satisfied when planting each and every one of these trees:

•"Red Maple"
•"Yellow Poplar or Tuliptree"
•"Red and White Oak"
•"Flowering Dogwood"
•"Sycamore"
•"American Elm"
•"River Birch"
•"American Holly"
•"Redbud"
•"Conifers"

No Tree Is Perfect


Remember, all yard trees have good and bad characteristics. It is a rare tree that will satisfy your needs throughout its entire life span. A tree can outgrow its original purpose very quickly or grow into its intended purpose very slowly. Understanding this concept is the key to proper tree planting in your yard.

It is extremely important you understand that your tree needs early attention after planting and correct care and attention as it matures. You can permanently harm your tree by incorrect placement and improper care.
