Which makes it all the more alarming that across the country, swathes of gum trees are dying without obvious cause. In forests from Western Australia to the island state of Tasmania, trees that should be living for more than 400 years are mysteriously dying before reaching their 100th birthday.he same is happening to the Tuart trees (Eucalyptus gomphocephala) in the Yalgorup National Park in Western Australia. Since fires were suppressed in 1976, the West Australian peppermint tree (Agonis Flexuosa) has flourished at the expense of the gums (Botanical Review, vol 75, p 191).
