The 2,000-years-old Giant sequoia is making current headlines with researchers finding it to be growing faster with age.

Recently we have heard news of Giant Sequoias becoming the second biggest tree in the world but experts are now noticing that aging giant sequoia trees are growing faster than ever with few of the oldest and tallest trees producing more wood averagely in their old age than they did when they were younger.

Mr. Steve Sillett, a professor at Humboldt State University in California has recently conducted a research on the big trees. He has noticed that most of the long-lived trees like coast redwoods and Australia's Eucalyptus regnans along with the Giant Sequoias have increased in their wood production during old age.

The above findings were revealed in an article Sillett that was published in the journal Forest Ecology and Management.

Explaining about the phenomenon that is behind the increase in the wood production, Mr. Sillett said that due to longer life span, a tree's leaf area increases with the expansion of its crown, which further allows leaves to produce more sugars through photosynthesis. It is actually these sugars that build wood across a growing cambium.

"What we're finding," Sillett said, "is that the rate of wood production in some species doesn't slow down until a tree gets to the end of its lifetime."
