A handful of rare Wollemi pine saplings, propagated from a secret population in the Blue Mountains, are being auctioned off to mark 30 years since the species’ discovery. The pine’s last wild community consists of just 46 adult and 43 juvenile trees in a secluded rainforest canyon in a World Heritage-listed area north-west of Sydney. According to fossil records, the critically endangered “dinosaur tree” dates back more than 90 million years, and was presumed to have gone extinct around 2 million years ago, until a remnant grove was stumbled upon in 1994. The auction is the first time saplings that are each genetically distinct will be released to the public. …There’s no estimate on how much the saplings will sell for, but saplings at previous auctions have sold for hundreds to thousands of dollars.
