It is the Sitka spruce (Paicea chitchensis), an exotic species originally from Alaskan trees.

Guinness calls the tree “unique” because its closest association is 250 km away in the Auckland Islands. Tree enthusiasts and scientists from all over the world travel there to see the spruce, which is just nine meters tall. It is oddly shaped, widely spread and not thin. According to the report, year after year, scientists have removed the top to serve as a Christmas tree. Wind also destroys wood in severe weather.

Giant flowers

Recently, this tree has become world news. Not because he is alone there, but because he is surrounded by colorful herbaceous flowers to rich flora and fauna (Megaherbs) to sea lions and albatrosses. No, researchers from New Zealand have found that this tree ‘can reveal the secrets of CO storage’.2 In the Southern Ocean”, etc Guardian reports .

The age of the tree has been established at over a hundred years, it was planted in 1900 by the then Governor of New Zealand, Lord Runfurly. That is why this tree is also known as Ranfurli tree.

How could that century-old lone tree on Campbell Island solve climate questions?

How could that century-old lone tree on Campbell Island solve climate questions? Very simply, Jocelyn Turnbull, an Antarctic scientist from New Zealand, says: “If you study growth rings, you can find out how much carbon is stored in them. Because the Southern Ocean is not just about CO2 Absorbs but gives back, this return can be read by taking a ‘core sample’ in the tree, with a deep hole in the trunk. That way you can understand the speed at which it happens.

‘Great Pleasure’

Another scientist, Australian biologist Jonathan Palmer, considers the tree “a historian, a chronicler of human involvement on Earth.” “Seeing the tree for the first time was a great feeling,” he says in an email.
