HyperionTallest Redwood • 600 years old • 379.1 ft. tall • Volume:18,600 cu. Ft.
Redwood uses • Coast Redwood lumber is highly valued for its beauty, light weight, and resistance to decay. It is also resistant to fire since it does not burn well due to its lack of resin. • Because of its impressive resistance to decay, redwood was extensively used for railroad ties and trestles. Redwood burls are used in the production of table tops, veneers, and turned goods.
Largest TreeThe General Sherman • Sequoia Nation Park • 2,200 years old • Diameter: 36.5 ft. • Circumference: 102.6 ft • Volume: 52,500 cu. Ft • Height: 291 ft. • 119.3 miles of 1x12 boards • Could be cut from this tree.
Baobab tree in Africa • The amazing baobab (Adansonia) or monkey bread tree can grow up to nearly 100 feet (30 m) tall and 35 feet (11 m) wide. Their defining characteristic: their swollen trunk are actually water storage - the baobab tree can store as much as 31,700 gallon (120,000 l) of water to endure harsh drought conditions.
Baobab • Baobab trees are used as restrooms, churches, prisons and homes.
Baobab trees • Can be up to 400 years old
Kauri trees • Agathis australis, commonly known as the kauri, is a coniferous tree found in the northern districts of New Zealand’s North island. It is the largest (by volume) but not tallest species of tree in the country, standing up to 50m tall in the emergent layer above the forest's main canopy.
Kauri trees • Agathis australis can attain heights of 40 to 50 metres and trunk diameters big enough to rival Californian Sequoias at over 5 meters. The largest kauris do not attain as much height or girth at ground level but contain more timber in their cylindrical trunks than a comparable Sequoia with its tapering stem. • The largest specimen of which there is any known record grew on the mountains at the head of the Tararu Creek. This tree was known as The Great Ghost. this tree was 8.54 metres in diameter, and 26.83 metres in girth.
Kauri trees • Trees can normally live longer than 600 years. Probably many individuals exceed 1000 years. • as they gain in height, the lowest branches are shed, preventing epiphytes from climbing. • The flaking bark defends it from parasitic plants, and accumulates around the base of the trunk. On large trees it may pile up to a height of 2 m or more.
Kauri timber • Use is restricted, in the past the size and strength of kauri timber made it a popular wood for construction and ship building, particularly for masts of sailing ships due to its parallel grain and the absence of branches extending for much of its height. Kauri crown and stump wood was sought after for ornamental wood paneling as well as high-end furniture.
Eucalyptus spp. • Several eucalypts are among the tallest trees in the world. Eucalyptus regnans, the Australian Mountain Ash, is the tallest of all flowering plants. The tallest measured specimen is 97 metres tall. There are only two taller tree species: the Coast redwood and the Douglas – fir. a Eucalyptus regnans tree in Australia is believed to have measured 143 m (470 ft); another Australian eucalyptus almost certainly had been over 150 m (492 ft) tall.Neither of these trees is still standing. • 700 species of Eucalyptus
Eucalyptus uses • Used as timber, firewood and pulpwood. • Fast growth also makes eucalypts suitable as windbreaks. • Eucalypts draw a tremendous amount of water from the soil through transpiration. They have been planted in some places to lower the water table and reduce soil salination. • Eucalypts have also been used as a way of reducing malaria by draining the soil.
Eucalyptus uses • Eucalyptus oil is readily steam distilled from the leaves and can be used for cleaning, deodorising, and in very small quantities in food supplements; especially sweets, cough drops and decongestants. Eucalyptus oil has insect repellent properties and is an active ingredient in some commercial mosquito repellents.
Circus Trees • As a hobby, bean farmer Axel Erlandson shaped trees - he pruned, bent, and grafted trees into fantastic shapes and called them “Circus trees." For example, to make this "Basket Tree" arborsculpture, Erlandson planted six sycamore trees in a circle and then grafted them together to form the diamond patterns.

Aspen trees • Pando or the Trembling Giant in Utah is actually a colony of a single Quaking Aspen (Populus tremuloides) tree. All of the trees (technically, "stems") in this colony are genetically identical (meaning, they’re exact clones of one another). In fact, they are all a part of a single living organism with an enormous underground root system. • Pando, which is Latin for "I Spread," is composed of about 47,000 stems spread throughout 107 acres of land. It estimated to weigh 6,600 tons, making it the heaviest known organism. Although the average age of the individual stems are 130 years, the entire organism is estimated to be about 80,000 years old!
Montezuma Cypress • ("The Tule Tree") is an especially large Montezuma cypress (Taxodium mucronatum) near the city of Oaxaca, Mexico. This tree has the largest trunk girth at 190 feet (58 m) and trunk diameter at 37 feet (11.3 m). For a while, detractors argued that it was actually three trees masquerading as one - however, careful DNA analysis confirmed that it is indeed one magnificent tree.
Banyan tree • The Banyan tree is named after "banians" or Hindu traders who carry out their business under the tree. Even if you have never heard of a Banyan tree (it was the tree used by Robinson Crusoe for his treehouse), you’d still recognize it. The shape of the giant tree is unmistakable: it has a majestic canopy with aerial roots running from the branches to the ground.
The Lonely Tree of Ténéré • The Tree of Ténéré or L’Abre du Ténéré was the world’s most isolated tree - the solitary acacia, which grew in the Sahara desert in Niger, Africa, was the only tree within more than 250 miles (400 km) around. • The tree was the last surviving member of a group of acacias that grew when the desert wasn’t as dry. When scientists dug a hole near the tree, they found its roots went down as deep as 120 feet (36 m) below to the water table! • Apparently, being the only tree in that part of the wide-open desert (remember: there wasn’t another tree for 250 miles around), wasn’t enough to stop a drunk Libyan truck driver from driving his truck into it, knocking it down and killing it!
Bristlecone pine • The oldest living tree in the world is a White Mountains, California, bristlecone pine (Pinus longaeva) named Methuselah after the Biblical figure who lived to 969 years old. The Methuselah tree, found at 11,000 feet above sea level, is 4,838 years old - it is not only the oldest tree but also the oldest living non-clonal organism in the world.Before Methuselah was identified as the world’s oldest tree by Edmund Schulman in 1957, people thought that the Giant Sequoias were the world’s oldest trees at about 2,000 years old. Schulman used a borer to obtain a core sample to count the growth rings of various bristlecone pines, and found over a dozen trees over 4,000 years old. The story of Prometheus is even more interesting: in 1964, Donald R. Currey then a graduate student, was taking core samples from a tree named Prometheus. His boring tool broke inside the tree, so he asked for permission from the US Forest Service to cut it down and examine the full cross section of the wood. Surprisingly the Forest Service agreed! When they examined the tree, Prometheus turned out to be about 5,000 years old, which would have made it the world’s oldest tree when the scientist unwittingly killed it!
Prometheus stump • Today, to protect the trees from the inquisitive traveler, the authorities are keeping their location secret (indeed, there are no photos identifying Methuselah for fear of vandalism).
Tree communication 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.
Tree superstitions • Knocking on wood for good luck originated from primitive tree worship when rapping on trees was believed to summon protective spirits in the trees.
Tree superstitions • Green man – Pagan fertility or nature spirit. The motif is used in architecture.
Trees cool the land • 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.
Trees and global warming • A mature tree removes 48 pounds of carbon dioxide (C02) per year from the air (roughly 10 tons per acre). • The amount of carbon stored annually by an acre of trees is approximately equal to the amount released by burning 1,000 gallons of gasoline. • A tree that provides shade and wind protection to buildings can indirectly cause, via energy conservation, reductions in carbon dioxide emissions equal to 15 times the amount of carbon dioxide the tree will absorb.
Trees and global warming • One acre of trees annually consumes the amount of carbon dioxide equivalent to that produced by driving an average car for 26,000 miles. That same acre of trees also produces enough oxygen for 18 people to breathe for a year. • A deciduous tree, like the American beech, that is 80-100 years old has about 1,600 square yards of leaf surface area to which dust particles can adhere. • A healthy tree stores about 13 lbs. of carbon each year, and a healthy acre of trees can store 2.6 tons of carbon a year.
Per capita wood consumption • It takes the wood from a 100-foot tree to keep the average American supplied for a year with newspaper, books, magazines, tissues, paper towels, housing materials, furniture, desks, fences, boxes and other assorted wood products. On the average that use amounts to: • 613 lbs. of paper products • 200 square feet of 1" thick lumber • 87 square feet of plywood • 59 square feet of insulation board, particle board and hardboard
Vital statistics for that 100-foot tree: • 18" in diameter at the base • 100 feet tall with a 60-70 foot crown spread 0 weighs about 4,100 lbs. at harvest • grew 200,000 leaves @ 120 lbs. per year or 3,600 lbs. over its lifetime • 1,300 lbs. of roots (an additional 2,000 lbs. were grown and discarded) • 100 lbs. of nutrients retained in the wood (twice that amount were returned to the soil) • took up over 5,000,000 gallons of water from the soil and transpired it into the air; 350 gallons of water (2,900 lbs.) were retained • 6,000 lbs. of oxygen given off 80 ft. tree
Trees effect on air quality • For every pound of wood produced by a tree, it also provides a pound of oxygen and uses almost 1.5 pounds of carbon dioxide. Or an acre of trees uses 5,880 pounds of carbon dioxide and gives us 4,280 pounds of oxygen each year.
Trees effect on air quality • Trees are nature's air conditioners. A single tree can transpire 100 gallons of water from its leaves in a single day. The cooling provided by this single tree is equivalent to five average room air conditioners running 20 hours per day. An acre of urban forest or park will transpire more than 1,600 gallons of water per day.
A large tree may have 200,000 to 400,000 leaves, which act like a continuous air filter. An acre of trees may remove as much as 13 tons of dust each year. Streets with trees have 3,000 particles per liter of air, compared with 10,000 to 12,000 in streets without trees. Trees also remove heavy metals. One study in Connecticut estimated that a single sugar maple tree, 1 foot in diameter, removes in one growing season 60 mg of cadmium, 140 mg of chromium, 820 mg of nickel and 5,200 mg of lead. Trees serve as moderate filters of some gaseous pollutants such as sulfur dioxide and carbon monoxide.
