Fun Facts about Trees

General

  • Trees keep our air supply fresh by absorbing carbon dioxide and producing oxygen.
  • In one year, an acre of trees can absorb as much carbon as is produced by a car driven up to 8700 miles.
  • Trees provide shade and shelter, reducing yearly heating and cooling costs by 2.1 billion dollars.
  • Trees lower air temperature by evaporating water in their leaves.
  • The average tree in metropolitan area survives only about 8 years!
  • A tree does not reach its most productive stage of carbon storage for about 10 years.
  • Trees cut down noise pollution by acting as sound barriers.
  • Tree roots stabilize the soil and prevent erosion.
  • Trees improve water quality by slowing and filtering rain water as well as protecting aquifers and watersheds.
  • Trees provide protection from downward fall of rain, sleet, and hail as well as reduce storm run-off and the possibility of flooding,
  • Trees provide food and shelter for wildlife.
  • Trees located along streets act as a glare and reflection control.
  • The death of one 70-year old tree would return over three tons of carbon to the atmosphere.

Tree Biology

  • Trees are the longest living organisms on earth.
  • Trees and other plants make their food through a process called photosynthesis.
  • The inside of a tree is made of cork, phloem, cambium, and xylem.
  • The xylem of a tree carries water from the roots to the leaves.

Trees and the Environment

  • Trees renew our air supply by absorbing carbon dioxide and producing oxygen.
  • The amount of oxygen produced by an acre of trees per year equals the amount consumed by 18 people annually. One tree produces nearly 260 pounds of oxygen each year.
  • One acre of trees removes up to 2.6 tons of carbon dioxide each year.
  • Shade trees can make buildings up to 20 degrees cooler in the summer.
  • Trees lower air temperature by evaporating water in their leaves.
  • Tree roots stabilize soil and prevent erosion.
  • Trees improve water quality by slowing and filtering rain water, as well as protecting aquifers and watersheds.
  • The cottonwood tree seed is the seed that stays in flight the longest. The tiny seed is surrounded by ultra-light, white fluff hairs that can carry it on the air for several days.

Record-setting Trees

  • One of the tallest soft wood trees is the General Sherman, a giant redwood sequoia of California. General Sherman is about 275 ft or 84 m high with a girth of 25 ft or 8 m.
  • The 236 ft or 72 m high Ada Tree of Australia has a 50 ft or 15.4 m girth and a root system that takes up more than an acre.
  • The world’s tallest tree is a coast redwood in California, measuring more than 360 ft or 110 m.
  • The world’s oldest trees are 4,600 year old Bristlecone pines in the USA.

Trees and Science

  • Dendrochronology is the science of calculating a tree’s age by its rings.
  • Tree rings provide precise information about environmental events, including volcanic eruptions.
  • A mature birch tree can produce up to 1 million seeds per year.
  • Moon trees were grown from seeds taken to the moon by Stuart Roosa, Command Module pilot of the Apollo 14 mission of January 31, 1971. The effort included 400-500 seeds, which orbited the moon on the first few days of February 1971. NASA and the USFS wanted to see if being in space and in the moon’s orbit would cause the seeds to grow differently than other seeds.

More Tree Facts

A single edition of a daily newspaper uses the wood from approximately 5,000 trees to make the paper.One tonne of recycled paper saves approximately 15 trees and their habitat.
The average tree will drink approximately 2,000 litres of water each year.
Tree Facts That Make You Stop and Think!

  1. Trees receive an estimated 90% of their nutrition from the atmosphere and only 10% from the soil.
  2. Trees grow from the top, not from the bottom as is commonly believed. A branch’s location on a tree will only move up the trunk a few inches in 1000 years.
  3. No tree dies of old age. They are generally killed by insects, disease or by people. California Bristlecone Pines and Giant Sequoias are regarded as the oldest trees and have been known to live 4,000 to 5,000 years.
  4. There are about 20,000 tree species in the world. The United States has one of the largest tree treasuries second only to India.
  5. The largest area of forest in the tropics remains the Amazon Basin, amounting to 81.5 million acres.
  6. Arbor Day was first observed in Nebraska in 1872. That state is now home to one of the world’s largest forests planted by people – over 200,000 acres of trees.
  7. Some trees can “talk” to each other. When willows are attacked by webworms and caterpillars, they emit a chemical that alerts nearby willow of the danger. The neighboring trees then respond by pumping more tannin into their leaves making it difficult for the insects to digest the leaves.
  8. Knocking on wood for good luck originated from primitive tree worship when rapping on trees was believed to summon protective spirits in the trees.
  9. Trees can induce rainfall by cooling the land and transpiring water into the sky from their leaves. An acre of maple trees can put as much as 20,000 gallons of water into the air each day.
  10. The most massive living thing on earth is the Giant Sequoia in the Redwood Forest of California. It stands nearly 30 stories tall and 82.3 feet in circumference. Its weight is estimated at 2,756 tons.
  11. In Arnold, California, a tree still stands with a legible inscription carved into it in 1849 by pioneers blazing paths to California during the Gold Rush. The inscription reads “49 Road.”

Facts

  • Trees help us breath by taking carbon dioxide out of the air and producing oxygen. Carbon dioxide, produced from burning fossil fuels, is the greenhouse gas most blamed for trapping heat in the atmosphere and linked to global climate change. One acre of trees produces enough oxygen for 18 people to breathe each day and eliminates as much carbon dioxide from the air as is produced from driving a car 26,000 miles.
  • Tree leaves help trap and remove tiny particles of soot and dust which otherwise damages human lungs.
  • Tree root networks filter contaminants in soils producing clean water.
  • Trees prevent erosion by trapping soil that would otherwise become silt. Silt destroys fish eggs and other aquatic wildlife and makes rivers and streams shallower, causing more frequent and more severe flooding. Trees along streams also hold stream banks in place to protect against flooding.
  • In the Chamblee area, the loss of 44% of its tree cover has resulted in storm water runoff problems costing $129 million.
  • To meet state sewer standards, the City of Atlanta is spending $240 million to counter effects associated with the loss of tree canopy.
  • By creating shade, trees moderate temperatures both globally and in the micro-climates of cities and counties.
  • Tree loss in Atlanta and neighboring counties has resulted in urban “heat islands” with temperatures 3-10 degrees above the surrounding countryside. The hot weather dome over the Atlanta area has changed local weather patterns including reducing rain in some areas and increasing the intensity of thunderstorms in others.
  • “Heat islands,” created by tree loss, also exponentially increase air pollutants. When pollutant chemicals are superheated by high air temperatures, they become more volatile and interact with each other to create ground level ozone which would not happen at lower temperatures. That is why Atlanta’s most dangerous levels of air pollution occur in the summer.
  • Planting 30 trees each year offsets greenhouse gases from your car and home.
  • Three trees located strategically around your house can cut air conditioning bills in half. On a larger scale, the cooling effects of trees can save millions of energy dollars.
  • Trees create a sense of privacy in urban environments.
  • Trees create buffers to reduce noise.
  • The presence of trees in urban neighborhoods has been linked to less crime.
  • Almost all woodpeckers can dig out holes for nests only in standing dead trees or the dead stubs on live trees and many other wildlife species depend on dead wood for nesting.
  • Dead and decaying trees on the ground replenish soils by returning important nutrients, and provide food resources for many types of wildlife.
  • Trees provide substances with medicinal values such as the active ingredients used in asthma medications and cough remedies. Aspirin is derived from the bark of a willow tree.
  • Trees provide green scenery that has been shown to speed up patient recovery in hospitals and reduce stress.
  • Property values of homes with trees in the landscape are 5 – 20% higher than equivalent properties without trees.
  • 60% of Atlanta’s natural tree cover has been removed over the last 20 years.
  • Metro Atlanta is loosing trees at the rate of 50 acres a day according to NASA.
  • The “State of Our Urban Forests” study recommended that healthy cities aim for a 40% tree cover (equivalent of 20 large trees per acre) to ensure their ecological, economic, and social sustainability.
  • Atlanta has an average tree cover of 27%, Boston has tree cover of 21.2, Austin 34%, Baltimore 31%, Milwaukee 18%, Chicago 11 percent, and New York City has 16.6 percent.
  • A recent survey by University of Georgia and Valdosta State University researchers shows that 85% percent of Georgians said they would approve some limits on private property rights if they were necessary to protect the environment.

  3. सगळे ठीक आहे. वाचायला बरे वाटते. अमेरीकेत वॄक्ष संवर्धन अतिशय चांगल्या पद्दतीने होते. मला वाटते की जो पर्यंत तिथली कही माणसे आपल्याकडे येऊन आपल्या राजकारणी व इतर so-called उच्च पतिष्ठित कॉरपॉरेट क्षेत्रातील व्यक्तींची या वद्दल कान उघाडणी केल्याशिवाय जाग येणार नाही. सर्वात जास्त वॄक्षांची हानी ही रस्त्ता रूदीकरण व नागरी वसाहतींचे मोठे प्रोजेक्स्ट्स अंमलात आणताना होतात. सिंहगड रोडवरचे मोठमोठे वॄक्षांचे काय झाले. त्याची नुकसान भरपाई कोणत्या स्वरूपात झाली. पवईचे डोंगर कोणी पोखरले. करणारे आणि त्यांना सरक्षण देणारे हे हातात हात घालून एकत्र फिरतात. तुमचे उद्दिष्ट खूपच चांगले आहे. परंतु जो पर्यंत पर्यावरणाची हानी करणार्‍यांना जरब बसत नाही तो पर्यंत असेच चालायचेच. तुमचा प्रयत्न एक एकक मानला तर पर्यावरणाची हानी करणार्‍यांची ताकद लक्ष एकक आहे. येऊरच्या डोंगरावर पर्यावरणाची हानी करून बंगले बांधणार्‍यांचे बंगले राष्ट्रीय संपत्ती म्हणून संवर्धन करणारे नेते जेथे आहेत तेथे त्यांच्या चेल्यांकदून काय अपेक्षा करणार. जनतेला जागरूक करायचे आणि नेत्यांना त्यांना हवे ते करायला मुभा द्यायची यांनी केलेल्या श्रमाचे चीज होत नाही

  4. WooW!
    This site has got much information abt trees which helped me in my project.

  5. an excellent collection of tree facts. valuable and motivating facts will surely have an impact on the readers. great job.

  6. cutting a tree is a double blow to the environment. you have lost a tree which acted like a carbon sink. By burning it or by letting it to slowly decay you release the stored Co2 back to the atmosphere
