Australia's Biggest, Tallest and Oldest Trees

There are many hobbies that one can choose. Stamp collecting, gardening, climbing tall trees. REALLY tall trees.

Former ISAAC Australian Tree Climbing Champion and international representative, Tom Greenwood, does exactly that. He travels around south-eastern Australia, with assistance from Brett Mifsud, in search of Australia's tallest trees. When he finds them, he measures them. Not all that unusual, you say. Not until you realise he does it with a tape measure, from the top of the tree!

Tom has measured many tall trees and has graciously agreed to publish the tallest of the tall and the biggest of the big on our website. Thanks Tom.

The tallest reliably documented tree ever measured was the Thorpdale Tree, a Mountain Ash (Eucalyptus regnans) growing at Thorpdale in Victoria, Australia. The tree was measured at 112.8m (370 feet) standing and 114.3m (375 feet) on the ground after it was felled in 1884. As you can see below, this is just a little taller than the living record holder; however, the Coast Redwoods are still growing and it is likely that some will eventually surpass this height. To see some of Australia's giant trees, have a look here http://www.nre.vic.gov.au/virtualexhibition/trees. The five tallest known trees in Australia are all in the Styx Valley, Tasmania.

For the desperately patriotic Aussie, there is still hope. Several strong but unverified reports of Mountain Ash were recorded at over 122m (400 feet) during the nineteenth century. As most were felled at the time, it is almost certain that no such tall trees currently exist. We can hope, however, that if we preserve enough of our forested areas that one day these tallest of the tall will once more grace our planet.

Australia's Tallest Living Trees

Tom measures the trees from the topmost leaf to the average point where the base of the tree intersects the ground. As of July 2004, these are the ten tallest living trees recorded in Australia.

Australia's Biggest Living Trees

Being tall is one thing, but being big is about volume. The biggest trees are not necessarily the tallest, but the ones with the largest volume. Typically these trees are still very tall, but have a larger average diameter than the very tallest.

El Grande Eucalyptus regnans Mountain Ash 80m 18.75m 380-410 Tasmania

The World's Tallest, Biggest and Oldest Trees

Tallest
The tallest living trees are Coast Redwoods (Sequoia sempervirens) growing in California, USA. These trees regularly exceed 100m and the tallest is the Stratosphere Giant, currently 112.6m (369 feet, 4.8in) (http://www.guinnessworldrecords.com).

NEW - Stratosphere giant surpassed by Hyperion, a Coast Redwood (Sequoia sempervirens) 379.1 feet (115.5 metres) (Planet Ark)

Biggest
The most massive trees are the Sierra Redwoods or Big Trees (Sequoiadendron giganteum), also growing in California. The largest, the General Sherman, is estimated at 2,000 tons (http://www.guinnessworldrecords.com).

Oldest
The USA also boasts the oldest living trees currently verified, Bristlecone Pine (Pinus longaeva). The largest recorded ring count for a Bristlecone Pine is 4,867 (http://www.guinnessworldrecords.com).

Australia can claim a little bit of glory in the age stakes in having the oldest genetically identical stand of trees. While no individual in this stand of Huon Pine (Lagarostrobos franklinii) in Tasmania is especially old by world standards, clones of the original tree have stood on the site for at least 10,500 years (http://www.dpiwe.tas.gov.au/inter.nsf/WebPages/BHAN-5494LA?open).

Huon Pines can be 2,000 years old and are Australia's oldest living trees.

Australia may be set to claim the world's oldest tree record, as two specimens of the world's rarest eucalypt, the Mongarlowe Mallee (Eucalyptus recurva), which grow 40 metres apart, may be part of the same original tree. If so, they are estimated to be 13,000 years old! If not, the individuals themselves may be 3,000 years old, making them Australia's oldest trees (http://www.nationalparks.nsw.gov.au/npws.nsf/Content/Eucalyptus+recurva+a+mallee+draft+recovery+plan).

We also may have the oldest living plant, King's Holly (Lomatia tasmanica), with a clonal colony possibly up to 43,000 years old (http://www.parks.tas.gov.au/veg/lomatia/lomatia.html).
