IT’S JUST AFTER lunchtime, the morning rains have finally cleared and the sun begins breaking through the clouds. Max Breckenridge, a captive release project officer with BirdLife Australia (BLA) is slowly walking along a dirt road that cuts through a patch of untouched spotted gum–ironbark forest in the Lower Hunter Valley in New South Wales.
There were expectations it would reveal much about the evolution of this continent’s largely unique mammal fauna, and it has. But to most scientists working in Australian wildlife conservation, it didn’t seem to have a lot of practical relevance.
Below the modern Brewarrina Weir in north-western New South Wales, a 2km bend holds the remains of this ancient structure, a complex of dry-stone walls and a site of engineering brilliance. Displaying advanced knowledge of river hydrology and fish ecology, the traps were designed to catch Murray cod, golden and silver perch and other fish, but allow breeding stock to pass through.
THAT FEBRUARY 2011 earthquake, which struck during the city’s lunch hour, was the most destructive in a series. It was the one that broke so many of the Central Business District’s verticals and horizontals – its buildings and the roads, sewers, water and gas pipes. It was shallow and ferocious. Its peak vertical ground acceleration of 2.2G (more than twice the acceleration of gravity) momentarily lifted parts of Christchurch to the sort of face-distorting speeds astronauts experience when they ascend into space.
IN 2004, THERE WAS no way David Williams, then an environmental science student at Deakin University, in Victoria, could have predicted the chain reaction a last-minute assignment submission would create. A paper he’d written outlined an environmental management plan that suggested using trained Maremma sheepdogs to protect little penguins from fox predation on Middle Island, off the coast of Warrnambool, in south-western Victoria.
