15.01.20. Under the Yum Yum Tree was a 1963 comedy film. But Tasmania, with accentuation on “mania”, likes to dedicate trees to living personalities. And climate activist Greta Thunberg has been chosen. Unlike the cornerstone of a church, or the keystone of a great bridge, or even a brass disc on a footpath outside the men’s toilet that people trip over, but a tree means the person identified was to be of fleeting importance. If memory serves, the large, Sydney department store, Anthony Hordern and Sons, was at one time the largest department store in the world, 52 acres of retail space. It was demolished in 1986. The company claimed a large Port Jackson fig tree on Razor-back Mountain near Camden NSW. After the demise of the Hordern dynasty vandals tried to poison the tree and in 2014 it is thought that lightning split the tree in two and blown over by the storm. And so died the Hordern motto,”While I live I’ll Grow!” I think I’d prefer a rose in dedication, “The Chaucer Bloom” might do! A giant eucalyptus tree in Tasmania has been named after teen sailing fan Greta Thunberg. It’s one of five mountain ash trees — also known as swamp or stringy gums, which measure up to 5.8m in diameter — in the Huon Valley dubbed by state conservation group Forestry Watch. The others: David Attenborough, Tim Flannery, Naomi Klein and Indian environmentalist Sunita Narain, Who?
