Endowment funding from ACTEW is helping one researcher extend his tree-ring study in Australia’s alpine regions. The end result could be a comprehensive climate record stretching back hundreds of years - with some sobering lessons for the future. BY SIMON COUPER

Humans have been keeping comprehensive scientific climate records for a few hundred years now, at most.

The availability and reliability of meteorological information from the past is a geographic game, depending on where you are in the world and who has been paying attention.

If you want to find hard data about things like average annual rainfall in Australia prior to the late 18th century – when Europeans arrived with their equipment and log books – then you need to think laterally. Or saw laterally, as is sometimes the case for Dr Matthew Brookhouse.

Brookhouse is a scientist and lecturer in the Fenner School of Environment and Society at ANU. He’s also a woodsman.

See the picture it shows the dead trees killed by 2003 fires. Amazing to see 1000's of hectares of dead trees (a wood burner paradise) but quite sad and spooky are these silent forests.

Its been so hot n low rain fall up in them Victorian hills since 2003 that tree recovery has been very slow. Not the post fire green wave of regrowth we are know for. The 2009 fires in Vic were the same years of dry n hot then the fire killed all and recovery has been slow. I got 60 acres in tough rock country that seems will take many more years to regrow. To our joy 2010 has rained above average, yippie and things seem to be turning around.
