When I was five, a tree was my best friend. An old peppercorn on Grandpa's little farm. I'd haul myself into its calloused arms and hide from the world in its foliage. Apart from the pleasure of looking down on unsuspecting adults, I could be Robin Hood in a one-tree Sherwood Forest or Johnny Weissmuller in his jungle. I fell out of my friend once while Tarzan-ing. Gashed a large chunk from a leg. Almost 70 years later, there's still a scar.

Later, in a different home, I befriended a eucalypt, using a resilient bough as a trampoline. Learning nothing from having plummeted from the peppercorn, I'd bounce happily in my haven in the heavens. I loved that tree - and fully understand why Heysen, Roberts, McCubbin and the rest devoted so much time and effort to painting arboreal portraits.

The old dead trees are the most fascinating - the countless trees lying in the gullies and up the hills that fell perhaps a century ago, pulling up their roots from the earth as they toppled. The great upheavals left rocks in their huge tentacles and, as they slowly rot, the trunks are home to populations of creatures, from goannas to wild pigs. As grey as tombstones in a cemetery they lie there, having outlasted generations of farmers, as they'll outlast me. In their own way they are as beautiful, more beautiful, than living trees.
