Charles Darwin's Best-Kept Secret

Posted by samzenpus on from the garden-of-darwin dept.

beschra writes "BBC writes of 'terra-forming' Ascension Island, one of the islands Charles Darwin visited. He and a friend encouraged the Royal Navy to import boatloads of trees and plants in an attempt to capture the little bit of water that fell on the island. They were quite successful. The island even has a cloud forest now. From the article: '[British ecologist] Wilkinson thinks that the principles that emerge from that experiment could be used to transform future colonies on Mars. In other words, rather than trying to improve an environment by force, the best approach might be to work with life to help it "find its own way."'"

    According to this AscensionIsland government press release :
    http://www.ascension-island.gov.ac/files/Anogramma%20press%20release_%20With%20images_%20Kew%20changes%2009%20June%202010.pdf

    "Goats were released onto Ascension by Portuguese explorers in the 1500s, and ate their way voraciously
    through the island’s greenery for 350 years before the flora was even described to science. By this stage, there wasn’t much left, and the introduction of rabbits, sheep, rats and donkeys, together with over 200 species of invasive plants, further squeezed out the island’s original plant inhabitants. With the rediscovery of Anogramma ascensionis the island’s surviving six endemic plant species are now boosted to a magnificent seven."

    "Something like the grand canyon, without any plant or animal life at all, is worthy of being preserved."

    Well it depends, for those lazy people who just pay for a helicopter tour over the top maybe, but as someone whose walked down it, some of the greatest memories I have are not simply the canyon itself, but witnessing life managing to thrive there. For example, having to stop for a family of deer to cross our path as the stag stood guarding the path, catching a magnificent picture of a Raven perched on a rock mid-squawk with a good shot of the canyon in the background, seeing the beautiful purple hue on some Opuntia species and their blooms, turning around on the way back up to see sheep with the biggest horns I've ever seen staring at me from the cliff side.

    Sure the likes of the Grand Canyon may look impressive without life, but it's far better with.
