A small army of specialist volunteers rose early at your Boolcoomatta Reserve this April, to discover which creatures had wandered its dunes and saltbush plains through the night.
As children across the
country opened their Easter eggs earlier this year, a team of dedicated Bush
Heritage scientists, partners and volunteers were already hard at work on Boolcoomatta Reserve in South Australia. Up since the crack of dawn, they were
busy trapping, counting and recording the creatures that had traversed the open
grasslands and desert outcrops overnight.
Boolcoomatta's unique animals
Listed as vulnerable in South Australia, the dusky hopping-mouse is about twice the size of a common house mouse and is characterised by its long feet, a long tufted tail and big ears.
These furry little Australian marsupials have a dark stripe between their ears on top of the snout, which stretches to their nose. Their sharp-pointed molars indicate they have a different diet from rodents.
This nocturnal rodent has olive-brown fur and a white belly and inhabits the arid and semi-arid areas of Western Australia, South Australia and New South Wales. It is distinguishable from the common house mouse by its larger ears, longer back feet and docile nature.

This was the first major survey to have been conducted on
the reserve in five years.
"The enthusiasm was tremendous," says Graham Medlin,
the survey coordinator. "You could hardly hear yourself at night in the
shearer's mess, with everyone talking excitedly about the day's events."
Corellas call at breakfast
The team, comprised of 33 adults, three teenagers
and one child, rose in silence with the sun each morning for four days. They
listened to the occasional raucous squawks of the corellas as they travelled in
4WDs to ten different capture sites set around the 63,000-hectare reserve.
"Boolcoomatta is such a delightful place," says
Graham, an Honorary Research Associate and sub-fossil expert at the South
Australian Museum, and member of the South Australian Field Naturalists
Society. "It's one of the best-managed reserves in which I've carried out
Hard work and great results
Prior to Bush Heritage purchasing the property in
2006, Boolcoomatta was an outback sheep station.
Since then, volunteers and
supporters like you have helped to reduce populations of feral animals, upgrade
Boolcoomatta's facilities to enable volunteers and contractors to stay and work
at the reserve (including on surveys like this one) and erect exclusion plots
to monitor and manage the effect of kangaroos and rabbits on the land.
"The health of the area's vegetation is a credit to
Bush Heritage and its supporters," Graham says.

pleased as he reached into the pitfall traps and carefully pulled out the
lively and sometimes ferocious creatures that had wandered into the traps
overnight. (The animals remain unharmed and are returned to their homes after

"We found several different rodents and marsupials,
as well as a large number of skinks, dragons and geckos," says Sandy. "There
were dusky hopping-mice, the Bolam's mouse and stripe-faced dunnarts."
A haven for wildlife
These creatures have found a haven at Boolcoomatta
that is difficult to find elsewhere. South Australia has the highest rate of
mammal extinctions of any state in the country, and Australia has the highest
rate of any country in the world.
But on Boolcoomatta, life looks prosperous. A
2010 bird survey showed significant increases in bird populations on the
reserve such as redthroats and white-winged fairy wrens.

exciting," says Sandy. "But we haven't reached the end of the story by any
means." With your ongoing support Boolcoomatta will continue to flourish.
Boolcoomatta Reserve was acquired in 2006
with the assistance of the Australian Government's National Reserve System
program and the Nature Foundation SA. We gratefully acknowledge The Native Vegetation
Council for their support of conservation activities on Boolcoomatt.
