One of the most unique Green Army Projects in Australia

Admin Aridrecovery - Wednesday, January 11, 2017
Few young people (aged 17-24) in Australia have the opportunity to get so close to the running and management of a world class conservation, research and education facility such as the Arid Recovery Reserve (our Project Partner). The wisdom and inclusiveness of Arid Recovery staff and their allies over the past 20-weeks has provided experiences our Participants will be able to use and reflect on in both their professional and personal lives. The Green Army is an Australian Government initiative which provides opportunities for Participants to work on local community and conservation projects, while gaining skills and training that can help them enter the workforce or improve their career pathways.

The work we have carried out at the Reserve falls into two broad categories: infrastructure maintenance, and science and research. Fence upkeep is integral to the Reserve’s success and ‘feral-free’ mantra. A large focus of this Project was replacing footnetting in areas where the integrity of the original skirt was starting to fail (through rusting and chemical breakdown). In some cases we used reclaimed netting from decommissioned pastoral fences within the reserve, to reduce pressure on a stretched budget. We also foot-netted the western fenceline of the 2nd Expansion, an area which was once used as a control, but now supports burrowing residents from the surrounding exclosures. 

All in a days work - Fencing is an integral part of Arid Recovery. 

The last few weeks of our Project included conducting vegetation monitoring using a quadrat-based method to quantify the impact of particularly bettongs on vegetation species inside the Reserve (using a selection of sites outside the Reserve for comparison). This replicates adds to a study first conducted in 2013. Given that current bettong populations are considered a little on the high side, we expect a marked contrast in plant condition. 

My team has also enjoyed participating in community activities such as regular market days, the Arid Recovery Quiz night and Christmas pageant. Together with contributions to the online presence of the Reserve (through blog and photo submissions), this has provided an insight into the importance integrated community involvement in maintaining the regional profile of the Reserve. The team also had the chance to visit Bon Bon Reserve to assist with wombat warren monitoring and maintenance tasks. 

Having the opportunity to get up close and personal to the unique wildlife of Arid Recovery lists as another highlight, and we are grateful for the generosity of visiting (and resident) researchers in incorporating the Green Army with some of their catching and processing activities.

The team regularly assisted at community events and fundraisers.

Bilby Tails Part II: Trials, Tribulations, Traps and Transmitters

Admin Aridrecovery - Friday, November 20, 2015

If you are a regular visitor of the Arid Recovery blog, you might have read a bit about the ‘bilby business’ that has been happening at the Reserve over the last few months. With the latest experiments on our resident transmitter-equipped bilbies wrapping up at the beginning of November, the final task of retrieving the transmitters has been on the agenda of many of the staff, students and volunteers at Arid Recovery.

For UNSW PhD student Lisa Steindler, removing the remaining tail transmitters from the last 10 of her caught Greater Bilbies (Macrotis lagotis) is just as important as putting them on. Not only are tail transmitters expensive pieces of equipment (retailing at over $200 each), they can be turned off and reused for further research at a later date. Re-catching bilbies can also provide some interesting data on how their weight and body condition has changed over time.

You may be asking “Shouldn’t it be easy to re-catch a bilby, especially if you can track where it is?” Prior to undertaking this task, I would have replied “Sure, we’ll just put a trap in the bilby’s burrow entrance, he’ll waltz on in and gladly hand over his transmitter!” After (finally) retrieving the last transmitter earlier this week, I can safely say that recapturing bilbies is not as easy as one may think. Below I have provided some short explanations of the possible scenarios that I came across during our time recapturing 10 bilbies.

Scenario 1: The tail transmitter falls off.

Transmitters recovered from bilbies: 5 (Romeo, Boomer, Bob, Betsy and Bruno)

Difficulty of retrieval: Varies from pleasantly easy when the bilby conveniently sheds the transmitter above ground on a sand dune (see figure 1), to back-breakingly difficult when it is lost metres down a burrow (see figure 2).

Figure 1: A tail transmitter left on a sand dune by Romeo. The most difficult part of retrieving this transmitter was bending down and picking it up. Credit: Lisa Steindler

Figure 2: Finding a transmitter in a burrow involves 3 steps. 1) Using the radio tracker, find the strongest signal emitting from the ground. 2) Dig, dig and dig some more. 3) Repeat as necessary until the transmitter is found. This process can take as little as 5 minutes or as long as 5 hours. Credit: Lisa Steindler

Scenario 2: The bilby is caught using a trap.

Transmitters recovered from bilbies: 4 (Bellamy, Brian, Bolt, Bullet and Bruce)

Difficulty of retrieval: Depends. The initial set-up of a pen trap can be labour intensive (figure 3), but if a bilby goes into one of the set traps on the first night, all that hard work pays off. On the other hand, trying to catch a bilby hiding in a bettong warren can prove difficult when the only animals you catch for 2 nights are Burrowing Bettongs (Bettongia leuser) and a goanna (Varanus gouldii). Once the bilby’s neighbours have been moved, trapping can be successfully achieved (see figure 4).

Figure 3:  A completed pen trap. Constructing a pen trap involves identifying the number of entrances in the warren, building a fence, complete with footnetting around said warren and wiring traps around and inside the fence. Thankfully, with the help of the Green Army, many hands make light work! Credit: Lisa Steindler

Figure 4: When a pen trap is set up around a warren, it is common to trap a neighbour or two instead of the target bilby. In this case, a Sand Goanna is being coaxed out of a trap by Green Army member Jesse. Credit: Adrian Friedel

Scenario 3: Volunteers are led along a 3-week chase by Bill, a cunning escape artist bilby.

Transmitters recovered from bilbies: 1 (Bill)

Difficulty of retrieval: I wouldn’t recommend this scenario to anyone. After 5 days of pen trapping (figure 5), over a week of rain delays, a further 3 days of failed burrow trapping (figure 6) and 1 mornings worth of digging, Bill was finally re-caught the same way he was caught (figure 7). In a net.

Figure 5: Some may think that 6 traps for one bilby might be too much. In this case, it proved to be not enough, with Bill the bilby escaping under the fence from this pen. Credit: Lisa Steindler

Figure 6: Trying a different tact. After residing in a few single-entrance burrows, we thought Bill might fall for a well-baited trap. As you can see, we were wrong. He burrowed straight under instead. Photo Credit: Sam Fischer

Figure 7: Success! After escaping a pen trap, and burrowing around several burrow traps, Bill was caught by digging behind his burrow, flushing him out and into a net. Credit: Bec West

Now, as the last removed tail transmitter is turned off, I’ve had a moment to reflect on the past few weeks. Having the opportunity to work with (arguably) one of Australia’s most iconic endangered animals has been one of the many highlights during my time volunteering with Arid Recovery. The excitement of seeing those distinctive big ears, and the satisfaction of removing the transmitter after weeks of collecting data far outweighs the many early starts, hours behind the shovel, and patience-testing moments.

Green Army ‘fights’ for Arid Recovery values

Kimberley Solly - Friday, November 13, 2015

“It’s going to be a hotter-than-average summer”. I don’t know how many times I’ve heard that sentiment over the last few months, and judging by the conditions of last few weeks (and the swathes of meteorological and oceanographic data relating to El Nino) it’s a fact that’s hard to dispute.  For a Project like the Arid Recovery Reserve, this means the heat reflecting off those polished red rocks, and the hot sand that pours into your boots on the ascent of every dune, will be harder to bear than ever.  But I’m not deterred.  The necessity for vigilance regarding the maintenance and welfare of the Reserve’s infrastructure, and its many furry inhabitants is something that doesn’t go away just because it’s hotter than usual.  A team of motivated and dedicated ‘warriors’ is required, and that is something I will be proud to contribute this summer in my role as Supervisor for the Roxby Downs Green Army Project.

The Green Army is an Australian Government initiative open to young people aged 17-24, who are looking to develop skills, undertake training and gain experience in the delivery of conservation projects.  Through the Green Army programme, participants enhance their opportunities for careers and further training in conservation. The Roxby Downs Green Army Project works in partnership with the Arid Recovery Reserve to achieve goals relating to species conservation in the arid zone. My team is only small (three people) but we work diligently to complete a range of objectives including fence maintenance, pest and weed surveys and vegetation monitoring.

The values of the Arid Recovery Reserve stand for a lot of things. Among them is the demonstration that a lot of hard-work and dedication towards a particular cause can eventually pay off.  I like to think that my team is following in the footsteps of Reserve ‘pioneers’, who have dedicated much time and energy in building and maintaining this unique facility. One of the major drivers in achieving this is ‘passion’, and ‘passion’ is something I find reflected in all of my team members, whether it be a desire to learn more about local flora and fauna or just the willingness to work hard on a task for the satisfaction of seeing a result take effect.  Each set of eyes on the Reserve improves the ability to detect unusual diggings or evidence of species that may (or may not) supposed to be there, and contributes towards the ever-expanding record of opportunistic sightings and phenomena.

The opportunity to get up close and personal with some of the Reserve’s furry (and sometimes scaly) critters is a fantastic reward and definitely something my team looks forward to. When a visiting researcher sticks their hand up looking for assistance, we are quick to jump at the opportunity.  Constructing little pens to trap burrowing animals is a job that requires multiple sets of eventually blistered and calloused hands, but the 5am starts and the hordes of flies are soon forgotten when given the opportunity to handle and process a captured bettong or a bilby. We are very lucky.

I want my team members to come away from this Project, at the end of February, seeing this unique environment through different eyes, and knowing that they have contributed towards important conservation goals.  We are currently looking for an additional team member for the summer and the next Green Army Project begins in February (and will run for around 22 weeks). Anyone who is interested or has any questions is invited to contact me by emailing me at

Kimberley Solly - Wednesday, November 04, 2015

Lisa Steindler is not like many other PhD students. Not many PhD students can say that they travel over 1,820 km from Sydney to be up close and personal with the Australian outback, but also a mammal that has faced great challenges. Like so many other Australian mammals, the Greater Bilby (Macrotis lagotis) has faced rapid population decline and severe range contraction associated with predation by cats and foxes. Believe it or not, but the Greater Bilby is actually the lucky one. Lucky in that the other species of bilby, the Lesser Bilby along with 29 other mammal species have gone extinct since European settlement around 250 years ago.

Lisa’s research is part of a much larger project occurring at Arid Recovery, which is the Australian Research Council Linkage project with the University of NSW that we’ve mentioned herehere and here. Titled ‘Tackling prey naïveté’, the research project is investigating the reasons for the extinction of our threatened species and why their re-introductions fail. It is believed that these failures may be because our threatened species might not have the correct anti-predator responses to introduced predators. While fenced reserves are providing much needed reprieve from cats and foxes, this protection may actually be hindering the restoration of threatened species in the long run. Isolation from predators may lead to more naïve populations that are unable to cope with predators (Blumstein 2006).

Beauty and naivety are a dangerous combination. We already know that the bilby is beautiful; Lisa’s task is to determine the degree of naïveté of the Greater Bilby. Lisa is investigating different behavioural characteristics of the bilby such as their vigilance behaviour when foraging (how often they look up to check for danger) and how they respond to the smell and sight of predators.

Thankfully Lisa is well versed in life in the semi-arid and arid zone, with stints as an intern, volunteer, and employee across reserves/sanctuaries such as Scotia Wildlife Sanctuary and Newhaven Sanctuary to name a few. While at Arid Recovery, Lisa has undertaken a number of different experiments, which all require a variety of skills. This year’s research kicked off with catching 30 bilbies across the Main expansion, First expansion and Red Lake expansion and fitting them with radio-transmitters attached to their tails. The ARC project and Arid Recovery intern Ruth Shepherd wrote an excellent summary on how to catch a bilby here.

We know that predators deposit urine and faeces throughout their home range, so Lisa is mimicking this to see how bilbies respond. Lisa tracks each bilby to their burrow (using their radiotransmitter) and then places scat from a cat, dog, rabbit or nothing (control) outside their burrow. Lisa has had to ask the Roxby Downs and Port Augusta locals for lots of cat and dog scats and has had help in collecting rabbit scats from outside the dunes by a whole heap of dedicated volunteers! The burrow entrance is then filmed using infrared motion detector cameras to see how the bilby responds when it emerges from its burrow.

In a different set of experiments Lisa has also been testing whether bilbies recognise a cat as a predator by placing a taxidermy model of a cat, rabbit or bucket (control) outside their burrows. If the bilbies recognise these odours or models as a predator threat they should show fear which can be measured by how vigilant they are. When Lisa gets back to Sydney she will watch the videos and score how long each bilby spends relaxed or vigilant and compare this to the scat or model that was outside their burrow.

Lisa has been flat out for three months and is deserving of a big rest, in between her casual role as an Australian fauna keeper at Taronga Zoo. Lisa's final task was to retrieve the radio-transmitters by using burrow and pen traps to re-trap bilbies and she leaves us with some wise words:

“If you want to work with digging animals, you’re going to have to learn to like digging holes”

Retrieving radio-transmitters is no easy feat! Credit: Lisa Steindler

Keep your eyes peeled for buffel grass

Kimberley Solly - Thursday, October 22, 2015

The Buffel Busters are a volunteer group that have worked tirelessly over the past three years to eradicate buffel grass (Cenchrus ciliaris) from the Roxby Downs region. Buffel grass is the most invasive weed that arid Australia has experienced. It grows quickly to form a dense monoculture, which is far more fire-loving and flammable than native plant species in the arid zone. Buffel grass can outcompete all native understorey plants and invasion of an ecosystem can significantly increase the frequency and intensity of fires, which can eliminate fire sensitive plants such as the long-lived Western Myall, Mulga and native pine trees which you see around Roxby downs. The long term efforts of Buffel Buster volunteers such as Reece Pedler means that the Roxby region has a fighting chance to nip buffel grass in the bud.


“We’re trying to protect our long-lived trees, and other plants and animals that are vulnerable to intense fires” said Reece Pedler.


We’ve talked about buffel grass before on the Arid Recovery blog (here and here), but we haven’t focussed on what you can do at home to identify buffel grass and make sure you’re not harbouring this declared weed in your garden. We've made a handy poster to help you identify buffel grass at home! Check it out now. 

Buffel grass has two key defining features which separate it from other grass species.


First defining feature: Remove an individual seed from the fluffy seed head. If the seed has 9 or more bristles coming from the base of the seed, it is buffel grass.


Many bristles come from the base of the individual seed. Credit: Cara Edwards

Second defining feature: After seeds are removed from the stem the stem is rough and wiggly.

Other features important for identifying buffel grass include one seed head per stem and the fluffy purple-straw coloured seed head. Some grass species which may be confused with buffel grass do not have the rough and wiggly stem and have less bristles that usually come from the middle or top of the seed burr.

It is particularly important to look out for buffel grass after rain events. Small infestations can be removed by digging out plants, ensuring the deep, tough root system is removed. If you would like more information or would like to join the Buffel Busters on their next working bee please contact Arid Recovery on (08) 8671 2402 or like us on Facebook!

Getting hands-on at Science Alive!

Admin Aridrecovery - Wednesday, August 26, 2015

With national science week wrapping up for another year, what better time to look back on the fun that was Science Alive! 


Bigger and better than ever, 2015 marked the event’s tenth anniversary, with a bustling crowd of 26,000 science enthusiasts over a massive three days. Hosting over 50 science-related organisations, you can’t help but be entranced by some of Australia’s hottest science and technology. Keen to get in on the action, Arid Recovery was surely never going to miss the chance to enviro-talk their way through the masses.

Watched over by Wodger the wedge-tailed eagle and bobby the burrowing bettong, the cosy stall was our most interactive yet. With few Australians (and even fewer children!) getting the chance to experience our vast arid interior, we brought the red sands and their stories down with us. Do you think you could guess what animals we share our lives with at Arid Recovery from just one touch? That is exactly what thousands of intrigued minds had the chance to try as they got hands-on with our fury friends. Hidden inside six boxes where the furs of an echidna, rabbit, greater stick-nest rat, cat, kangaroo, and dingo. With a few hints, many brave young scientists guessed correctly and learnt about some of the animals we help protect.  

Not to be outdone by some of the other innovative stalls at the expo, our digital 3D landscape gave everyone the chance to explore the home of our reintroduced burrowing bettongs. By clicking on the screen, visitors could try to find the warrens (burrows) of the native rabbit-sized kangaroo. This computer reconstruction of the arid landscape is part of new research into the ecology of Arid Recovery, but also helps us engage the public with their environment. So if you just can’t get enough of science, make sure to take your family to Science Alive 2016, or even better visit us for a tour

Flocking pigeons

Developer 2 (MM) - Wednesday, August 13, 2014

Over the past few months a group of volunteers have been watching the amazing site of thousands of Flock Bronzewings swarming across the arid landscape north of the Arid Recovery Reserve.

AR's resident cinematography, Travis Hague, has put together some footage of the phenomena.

Supporting Our Supporters

On World Environment Day we say thank you to the many wonderful people and organisations that support the work that we do in arid zone restoration.

On World Environment Day, June 5, Arid Recovery hosted a Supporter’s Night to say thank you to all the businesses and organisations that support the work of Arid Recovery. Recent rain prevented the event from being held at the Arid Recovery Reserve, so the Olympic Dam Football Club kindly donated their clubrooms for the night.

The outdoor entertaining area was transformed to create an ‘Arid Recovery experience’, with a temporary floppy-top fence bought in, skins, furs, maps and posters on show. Our resident bilby ‘Charlie’ as well as his taxidermy friends the stick nest rat, bettong and a bearded dragon were gathered from their usual home at the local Visitor Information Centre and proudly put on display to show some of the threatened and local fauna that have established populations inside the Reserve.

“Arid Recovery relies heavily on donations from individuals, groups, businesses and corporations, with every kind of donation, be it money, equipment, materials or labour all highly appreciated” explains Community and Education Assistant Sam Secker. “By hosting the Supporter’s Night we had the opportunity to show our gratitude and give a little bit back to the generous people and businesses that support our work.”

About 45 guests braved the wintry conditions to come along to the event.  As the spots of rain eased, guests gathered under the stars to be entertained by local musicians ‘Who’s on First’ and to meet with other locals and businesses. Hungry bellies were satisfied and wintry blues warmed with homemade pumpkin soup, gourmet kangaroo sausage and rocket rolls, and lamb cutlets with native herbs and spices, impressing all that attended. Guests came from far and wide, including local businesses from down the road, and some special guests in from as far as Adelaide for the night. Arid Recovery board members Garry Winter and Professor Bob Hill, the new AR Board representative from the University of Adelaide, also made the trip to Roxby Downs to show their appreciation for the support that we receive.

“It was great to have all our supporters in one place and give us the opportunity to mingle with one another,” grinned Sam. “I would especially like to say thanks to the people that made the night possible, Greyhound, Roxby Motor Inn, Alliance Airlines, ‘Who’s On First’, Woolworths, the Olympic Dam Football Club and of course the fabulous Arid Recovery staff.”

From the ocean to the outback – a visit from Port Lincoln High School

Developer 2 (MM) - Wednesday, August 13, 2014

Arid Recovery was abuzz with excitement as a group of students from Port Lincoln High School ventured from the sea-side fishing town to the outback to experience first-hand the wonders of the Reserve. Spending three nights camping at the field station, the seven students gained some hands on experience to complement the current studies they are undertaking in a Certificate II in Conservation and Land Management. The students participated in a range of monitoring activities including a native tracks workshop, where the students identified tracks of reintroduced species and then drew them in the sand, and a nocturnal spotlight walk through the sand dunes to catch a glimpse of some of the cute and furry critters.

Arid Recovery staff where fortunate enough to have the students assist with maintaining the predator proof fence, finishing 100m of footnetting in record time under the desert sun. The students were extremely proud of their efforts.

An opportunity to see some of the animals up close required the students to start super early with alarms set for 4:00am! The students learnt about trapping, processing and animal handling techniques, and successfully trapped 43 bettongs and one Western Barred Bandicoot. The animals were then released down warrens just as the sun was coming up to paint a beautiful desert sky.

A visit by Muso Magic topped off the week. They filmed the fencing efforts and interviewed the students for their upcoming TV show ‘Outback Tracks’ capturing the enthusiasm of the kids as they proudly discussed what they had learnt about conservation and the Arid zone.
