What is Tree ?

Osage Orange is the species of wood that produces the most heat when burned.

Street trees provide amenity to pedestrians

On hillsides or stream slopes, trees slow runoff and hold soil in place.

The world’s largest divided tree leaf to date was growing on a West African Raphia Palm. When measured, it was approximately 82 foot in length. Note: Only a very small percentage of tree species in the world have divided leaves.

Plants whose leaves die in autumn and fall off, such as elms, maples, and ashes, are called deciduous. In Utah nearly all evergreen woody plants have needle-like or scaly leaves and most deciduous woody plants have broad leaves. All vines commonly found in Utah have broad leaves and are deciduous.

The most recently discovered tree specie is the Wollemi Pine. It was discovered in September 1994, by, a New South Wales National Parks officer named David Noble in a secluded area in the Blue Mountains of the Wollemi National Park, approximately 124 miles west of Sydney Australia.

As a bonus, trees have a knack for soaking up soil pollutants, too. One sugar maple can remove 60 milligrams of cadmium, 140 mg of chromium and 5,200 mg of lead from the soil per year, and studies have shown farm runoff contains up to 88 percent less nitrate and 76 percent less phosphorus after flowing through a forest.

People are more likely to choose to walk along a street which has many street large trees

The tree specie with the largest undivided leaves is the Bigleaf Magnolia. The leaves are 7 to 12 inches wide and 12 to 32 inches long.

trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.

White Oak is the species of wood that is easiest to steam bend. With thin stock you can bend it, into an extremely small radius.

Trees help us breathe — and not just by producing oxygen.

Street trees provide a physical & psychological buffer between passing vehicles & pedestrians

The lightest American wood is Corkwood Florida. Its average weight/density/specific gravity is .21. It is native to the southeastern United States especially Florida.

Trees are the longest living organisms on Earth, and never die of old age. The Old List is a database of ancient trees that officially tracks old trees, their species, and location. Methuselah, from California’s White Mountains, comes in at over 4,800 years old.

Trees reduce UV-B exposure by about 50 percent, thus providing protection to children on school campuses and playgrounds - where children spend hours outdoors.

About half of all oxygen in the air comes from phytoplankton, but trees are a major source, too. Still, their relevance for humans' oxygen intake is a bit hazy. Various sources suggest a mature, leafy tree produces enough oxygen for two to 10 people per year, but others have countered with significantly lower estimates.

Street trees with large canopies give drivers the impression of narrower streets, which results in reduced speed & less associated traffic accidents & danger to pedestrians

The heaviest American wood is Lignum Vitae Holywood. Its average weight / density / specific gravity is 1.31. It is native to southern Florida.

Palm Sunday was named after the Palm tree because people took branches of Palm trees with them to greet Jesus Christ in Jerusalem.

Just like humans, trees need water to survive--and they drink a lot of it. In a single day, a large tree can consume 100 gallons of water out of the ground and discharge it into the air as oxygen and water vapor. Keep in mind that many conditions play a role such as the size of the tree, species of the tree, humidity, temperatures, sun exposure, etc.

Trees are Nature’s bounty. Trees are of many different kinds. There are flowering trees, which bear blossoms, and non-flowering ones, which do not bloom into flowers.

apple tree can yield up to 15-20 bushels of fruit per year and can be planted on the tiniest urban lot. Aside from fruit for humans, trees provide food for birds and wildlife.

Yet even without the oxygen, trees clearly offer plenty of other benefits, from food, medicine and raw materials to shade, windbreaks and flood control. And, as MNN's Matt Hickman reported in 2016, city trees are "one of the most cost-effective methods of curbing urban air pollution levels and combating the urban heat island effect." That's a big deal, since more than 3 million people die worldwide each year from illnesses linked to air pollution

The world’s tallest living uncut decorated Christmas tree is a Douglas Fir. It is approximately 160 foot tall, lighted with over 50,000 LED lights and is located in Blue River, Oregon USA.
