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 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.
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 360ft or 110m.
The world’s oldest trees are 4,600 year old Bristlecone pines in the USA.
Trees are the longest living organisms on earth.
Trees and other plants make their food through a process called photosynthesis.
Britains oldest tree is probably the Forthingall Yew in Tayside, which is believed to be over 3000 years old.
A fully-grown Oak in the UK grows, and sheds 250,000 leaves every year and produces around 50,000 acorns in good year.
Britain is thought to have the largest population of ‘ancient trees’ in Europe.
Tree rings can provide precise information about environmental events.
The world’s rarest trees are endemics of remote islands, some only known from single wild specimens, such as the St Helena Olive. Britains own endemic trees include Bristol Whitebeam which only grows naturally in the Avon Gorge.
Yew leaves may help in treatment of cancer. A drug called Taxol can be produced from them.
The height above sea-level at which trees cannot grow is called the treeline. This changes with latitude and in the Alps is approximately 7000ft, whilst in North Wales it is 1820ft.
The largest individual in the world is the Giant Redwood called the ‘General Sherman’, which has a height of about 275ft, a girth of 25ft and a volume of 52,500 cubic feet.
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.
