TREES FROM AROUND THE WORLD
(and their importance in general) And other interesting plants


Trees are a good symbol of dedication to a better quality of life for all. Trees are a source of life, and they provide a delicate balance to our ecosystem. Trees remove air pollution, filter out chemicals and agricultural waste in water, and they save communities across the country millions of dollars in stormwater management costs. Trees also help to improve community health by removing air and water pollution that can make you sick. Trees can also save you money at home by reducing energy costs for heating and cooling by anywhere from 10% to 50%. They help prevent soil erosion, as well as slowing down or putting a break on desertification

Plus trees even add value to your property!

FOR EVERY TREE YOU HAVE TO CUT DOWN, TRY TO PLANT TWO SOMEWHERE

Environmental Benefits of Trees

Trees alter the environment in which we live by moderating climate, improving air quality, conserving water, and harboring wildlife. Climate control is obtained by moderating the effects of sun, wind, and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter, we value the sun’s radiant energy. Therefore, we should plant only small or deciduous trees on the south side of homes.

Wind speed and direction can be affected by trees. The more compact the foliage on the tree or group of trees, the greater the influence of the windbreak. The downward fall of rain, sleet, and hail is initially absorbed or deflected by trees, which provides some protection for people, pets, and buildings. Trees intercept water, store some of it, and reduce storm runoff and the possibility of flooding.

Dew and frost are less common under trees because less radiant energy is released from the soil in those areas at night.

Temperature in the vicinity of trees is cooler than that away from trees. The larger the tree, the greater the cooling. By using trees in the cities, we are able to moderate the heat-island effect caused by pavement and buildings in commercial areas.

Air quality can be improved through the use of trees, shrubs, and turf. Leaves filter the air we breathe by removing dust and other particulates. Rain then washes the pollutants to the ground. Leaves absorb carbon dioxide from the air to form carbohydrates that are used in the plant’s structure and function. In this process, leaves also absorb other air pollutants—such as ozone, carbon monoxide, and sulfur dioxide—and give off oxygen.

By planting trees and shrubs, we return to a more natural, less artificial environment. Birds and other wildlife are attracted to the area. The natural cycles of plant growth, reproduction, and decomposition are again present, both above and below ground. Natural harmony is restored to the urban environment.

Trees Save Energy Strategically placed shade trees can reduce heating & cooling expenses by 10% to 50%. A single mature tree provides the cooling equivalent of five average air conditioners running 12 hours per day.
Trees reduce city temperatures 3 to 10 degrees.
Trees reduce glare on sunny days.
Trees are Good For Our Health
  • Shade trees provide protection from the harmful sun's rays.
  • Trees filter air contaminants, clean our air.
  • Trees provide privacy, promote healing & create a sense of relaxation and well-being.
  • Trees reduce noise pollution and soften harsh urban views.
  • Trees add beauty and natural character to our cities.
  • Trees absorb C02 and other dangerous gases while replenishing our atmosphere with oxygen.
  • Trees in good health can remove up to 50 pounds of carbon dioxide from the air every year.
  • A 32 ft tall Ash tree can provide 260Lbs of oxygen a year. Two trees are enough to supply the oxygen for each person every year.
  • 120 to 240 lbs of small particles and gases are absorbed by each mature tree a year.
Trees Conserve Water and Reduce Soil Erosion
  • Trees reduce surface water runoff from storms.
  • Trees reduce the amount of grease and oil transported to streams, a major source of ocean pollution.
  • Trees reduce soil erosion and sedimentation of streams.
  • Trees increase ground water recharging that is reduced by urban paving.
  • Trees shade other plants reducing their water requirements.

Jan went on her group walk, and someone knew about a sausage tree with enormous fruit that resemble sausages, in the park, only a few hundred yards from where we live. Its real name is Kigelia pinnata, and grows to to 15 metres in its native Africa.
The blood-red flowers of the tree bloom at night on long, ropelike stalks that hang down from the limbs of this tropical tree. The fragrant, nectar-rich blossoms are pollinated by bats, insects and sunbirds in their native habitat.
The mature fruits dangle from the long stalks like giant sausages. They may be up to 60cm long and weigh up to 6-8kg.

Mainly grown as a curiosity and ornamental, both for its beautiful red flowers and its strange fruit. There are also a range of traditional uses for the fruit, varying from topical treatments for skin afflictions, to treatment for intestinal worms. There are some steroid chemicals found in the sausage tree that are currently added to commercially available shampoos and facial cream.
The tree is a marginal tropical plant but can withstand light frosts.
It is very rare in Australia.


Robyn of Perth, wanted to tell us about the moving of a giant Boab tree:

The tree in question was estimated to be 750 years old and weighing 36 tonnes, is 14 metres high and its truck is 2.5 metres diameter You can read this interesting story
here
Western Australia is said to be the only place in the world where Boab trees are to be found. Every boab tree is unique. They have character and personality as you would expect of such an ancient creature. Some individual boab trees are 1500 years old and older, which makes them the oldest living beings in Australia, and puts them amongst the oldest in the world.
Aboriginals used the giants as shelter, food and medicine. For the white settlers they served as easily recognisable land marks and meeting points, and not to forget as impromptu prison cells.

The largest water lily in the world is the Vitória Régia, a native of the Amazon River basin. Its round leaves attain 2 m in diameter and have a pronounced up turned edge. When floating on the water it can sustain heavy weights, such as rabbit sized animals. When it blooms, its petals are white, often slight pink, with red rims.
The Legend
In olden times, on the margins of the majestic Amazon river, the beautiful young women of an indian tribe gathered to sing and dream of life. They stayed for long hours staring at the beauty of the white moon, and the mystery of the stars, dreaming of being one of them.

As the aroma of the tropical night pulled at their dreams, the moon laid an intense light on the waters, making Naia, the youngest of the tribe and a dreamer, climb a tree to try to touch the moon. She didn't succeed. The next day, she and her friends climbed the distant hills to feel with their hands the smoothness of the moon, but again they failed. When they arrived there, the moon was so high that all of them returned to the longhouse feeling disappointed and sad. They believed that if they could touch the moon, or even the stars, they would transform themselves into one of them.

The following night, Naia left the longhouse hoping to fulfill her dream. She took the river trails to stare at the river's waters. There was the full moon, resplendent, immense, quietly reflecting its image on the water's surface. Naia, in her innocence, thought the moon had come to bathe itself in the river and allow her to touch it. Naia dove into the deep waters and there disappeared forever.

The moon, feeling pity for the young lost life, transformed Naia into a giant flower - the Vitória Régia - with an inebriating perfume and petals that spread on the water to receive the full light of the moon.

Sharon tells us that B.C.'s flower is the Pacific Dogwood,
their bird is the Steller's Jay,
and their tree is the
Western Red Cedar.
The motto for their province is "Splendour without diminishment"!
And, of course the national Tree of Canada is the Maple

Has anybody heard of the American chestnut tree? No? Do you know why?
Because it is all but extinct. A hundred years ago it was one of the most abundant and useful trees in the Eastern United States. Its story is a genuine tragedy. The sender was just reading about it in Bill Bryson's book "A Walk In The Woods" and have transcribed an excerpt for you that I think you might find interesting and informative...

With each passing year the character of the American woods changed perceptibly. But until quite recent times - painfully recent times - one thing remained in abundance that preserved the primeval super-Eden feel of the original forest: the massively graceful American Chestnut.

There has never been a tree like it. Rising a hundred feet from the forest floor, its soaring boughs spread out in a canopy of incomparable lushness, an acre of leaves per tree, a million or so in all. Though only half the height of the tallest eastern pines, the chestnut had a weight and mass and symmetry that put it in another league. At ground level, a full-sized tree would be ten feet through its bole, more than twenty feet around. I have seen a photograph, taken at the start of this century, of people picnicking in a grove of chestnuts. It is a happy Sunday party, all the picnickers in heavy clothes, the ladies with clasped parasols, the men with bowler hats and walrus moustaches, all hand- somely arrayed on a blanket in a clearing, against a backdrop of steeply slanting shafts of light and trees of unbelievable grandeur. The people are so tiny, so preposterously out of scale to the trees around them, as to make you wonder for a moment if the picture had been manipulated as a kind of joke. But this is simply the was it was--the way is was over tens of thousands of square miles of hill and cove, from the Carolinas to New England. And it is all gone now.

In 1904, a keeper at the Bronx Zoo in New York noticed that the zoo's handsome chestnuts had become covered in small orange cankers of an unfamiliar type. Within days they began to sicken and die. By the time scientists identified the source as an Asian fungus called Endothia parasitica, probably introduced with a shipment of trees or infected timber from the Orient, the chestnuts were dead and the fungus had escaped into the great sprawl of the Appalachians, where one tree in every four was a chestnut.

Seldom has a tree been more helpless against an invader than the American chestnut against Endothia parasitica. It enters the chestnut effortlessly, devours the cambium cells, and positions itself for attack on the next tree before the tree has the faintest idea, chemically speaking, what hit it. It spreads by means of spores, which are produced in the hundreds of millions in each canker. The mortality rate was 100 percent. In just over thirty-five years the American chestnut became a memory. The Appalachians alone lost four billion trees, a quarter of its cover, in a generation.

Quite a story, isn't it? The only thing standing in the way of the chestnut's complete extinction is The American Chest- nut Foundation. They are desperately trying to develop a blight-resistant breed of the chestnut to reintroduce into the Appalachians. If you'd like to do some research you can find a lot more information online. Fascinating stuff. I'm just sorry I may never get a chance to see an American chest- nut.

Scientists are baffled by sudden decline of Aspen in the Rockies.

There is something doleful about the whisperingof the white barked Aspen trees that carpet the slopes of the Rocky Mountains. It is a sound of sickness and death. Scientists believe that up and down the mountain chain, the Aspen trees are beginning to vanish. As many as 10% have died or are ailing in parts of Arizona, Colorado and Utah according to the surveys. In parts of Alberta Canada, about 30% of the trees have died in 5 years. The greatest problem is that they are not sure what is affecting the trees. Researchers are focusing on the unusual reproductive system of the Aspen. Instead of distributing seeds, the trees sit upon hugely complex root systems. As older trees die, the roots send up shoots which become saplings, and thes eshoots are not appearing in the areas where the treees are in trouble.

One possiblility could be the presence of a previously undetected fungus. Recent periods of drought in the American west, could be to blame, as well as the eating of the shoots by herds of elk, or human interference from forest fires. Caterpillars are also thought to be responsible.
