Adding Trees to the Cropping Equation
Down in the depths of the Pye Laboratory, at the Black Mountain home of CSIRO Land and Water, plant physiologist Dr Richard Stirzaker is conducting an experiment that would send a chill through any tree-liberationist. Side by side, under blazing...
A Model of Versatility
Management options for lowering groundwater tables and making productive use of saline land have been tossed about by scientists, governments and landholders for decades. Technical reports by the hundred, perhaps thousand, chronicle countless means...
A Wizard with Wavelengths
Philip Kofoed follows the trail of an environmental troubleshooter whose investigative techniques reveal more than the eye can see. Songs and stories from our past often mention the coolabah tree, its generous shade providing welcome relief for many...
By Nature, Agriculture Has Its Limits
David Cudmore answers my question with conviction. `What we need is a high-yielding perennial wheat, and a good summer pasture grass that grows underwater in hot conditions.' Cudmore, his wife, Wendy, and sons Sandy and Charles, have a property...
Concern Surrounds the Secret Life of Sea Lions

Fatal Fungus Linked to Frog Declines

Greening the Nation by Cutting Red Tape
Bob, a Narrogin farmer, has been thinking ... `We should fence that bit of scrub down in the back paddock; save it for the honeyeaters,' he says to his wife, Anne. `But it'll cost a packet.' `No problem,' Anne says. `Just call this number. The...
Living with Saline Land
In many of Australia's salt-affected regions there will be extensive areas where salinisation processes cannot be reversed. Revegetation with salt-tolerant species, for functional, aesthetic and productive purposes, will be a key component of management...
Pine Ridge: A Catchment in Good Hands
On an overcast day in April, CSIRO technician Peter Richardson bids hello to a curious companion' a green tree frog, living most contentedly down an observation well, beside a road called Cattle Lane. Richardson unplugs the frog, dubbed Froggo,...
Rising Salt: A Test of Tactics and Techniques
In many parts of Australia, farming is a risky business. The country's capricious climate has always made a gamble of decisions such as when to sow crops or sell livestock. More recently, trends in world commodity markets have caused scrambled shifts...
Seeking Clues to Watertight Cropping
Dr Hamish Cresswell and his colleagues must have harvested enough fodder in the past three years to fatten all the domestic livestock in Australia. At least they would have if all their crops and pastures had been grown in paddocks rather than computers....
Small Signs of Fire in the Buttongrass
For many types of Australian habitats, the effect of bushfires on vertebrate fauna is fairly well understood. The effect of fires on invertebrate species, however, is still largely a mystery. Penny Greenslade, a researcher with CSIRO Entomology,...
Sugar's Bitter Sweet Dilemma
Brad Collis outlines efforts by the cane-growing industry to lessen its impact on the Great Barrier Reef. Tony Palmas has fished the reefs and estuaries along the coast near his 145-hectare cane farm at Ingham all his life. So did his father, and...
Turtles Moonlight in Safety
During their summer breeding season since time immemorial, green and loggerhead turtle hatchlings have popped out of the sand on the islands and beaches of north-west Western Australia. The little battlers take one blink and belt for the ocean to...
