Home sweet home

Pretty Digital - Wednesday, August 13, 2014

Here at Arid Recovery, it’s pretty quiet during the day - you could almost be excused for thinking that we don’t have any animals inside the Reserve!  However, at night time the Reserve is alive with a range of critters darting across dunes and foraging through foliage.

Many of the animals that live in the arid zone are nocturnal. This means that they sleep during the day and are active during the night when the weather is much cooler. It is often mammal species that are nocturnal; however reptiles and amphibians may also become more active at night during the warmer months.

So now that we know the animals are only seen at night, where do they go during the day?

Each of our re-introduced species has a unique home that they can retire to after a long night. These homes keep the animals safe and cosy, and can house one or a large number of critters, depending on the animal and its home.



  • The Greater Stick-nest Rat builds its home out of sticks (above). The nest is generally built around a bush and can be over 1 metre in height. Sticks and branches are dragged to the site in the rat’s mouth, with larger branches gnawed down to a manageable size and added to the nest. The sleeping sites within the nest contain soft vegetation and grass, with tunnels built from the outside to reach these points. 
  • Burrowing Bettongs construct a burrow in deep loam or sandy areas, and are the only member of the macropod family to shelter underground. The burrows often form warrens, which have multiple entrances. The floor of the warren is lined with vegetation to create nests for sleeping. Complex warren systems can have 11 or 12 entrances. One warren system found on Barrow Island had 120 entrances with about 60 bettongs living in it!  
  • Bilbies are powerful diggers, constructing a spiralling burrow which may be 3 metres long and up to 1.8 metres deep. The entrance to a bilby burrow is often under a small shrub and at Arid Recovery is usually left open. At other locations bilbies often backfill their burrow entrance, possibly to protect it from predators or to regulate the burrow temperature. Bilbies frequently dig new burrows and occasionally return to their old ones.
  • The Western Barred Bandicoot (WBB) shelters during the daylight hours in a nest. It digs a shallow hollow in the ground, usually under a low shrub and fills the hollow with sticks and leaves. A single entrance and exit point is disguised from predators using leaves, and the WBB will make a quick exit if disturbed by predators. Some WBB’s will use the same nest repeatedly over the course of the week, while others will move to a new nest each night. If caught out in the open a bandicoot will use another animal’s burrows to shelter in until the threat has gone away.

Many other animals are known to live underground at Arid Recovery, including sand goannas, scorpions, spiders and the incredible Trilling frog.

Merry Xmas to all...

To all our members, supporters and volunteers,

Thank you all for another fantastic year. Your help throughout 2013 whether it be at the Reserve, at an event or just by reading our newsletter is invaluable and we thank you one and all.

Arid Recovery could not achieve what it does without your support and we hope that we will see and hear from each and every one of you in 2014.

I would like to say a very special thanks to all AR staff for their amazing efforts this year. For those of you who have not been keeping up to date with our bettong project the AR staff, through the great organisational efforts of Cat Lynch, have achieved a super human feat of moving over 1500 bettongs – a record number unheard of previously by anyone, anywhere! So to Cat, Anni, Craig, Tina, Hayley & Vanessa who have worked throughout the year to make AR what it is I say thanks.

A special mention should also go to AR’s part-timers, Marty Kittle & Katherine Moseby. Marty, who is now in his 10th year of checking the AR fence, continues to be a great support to myself and all AR staff with his knowledge and easy going ways. Katherine, now as AR’s research scientist, has recently started on an amazing new project that will see AR research & the Reserve go onto bigger and better things over the coming years.

Have a safe and happy festive season and as a special treat our fabulous volunteer Alix Palmer has written an AR Xmas carol. We hope you enjoy.

Flora fun

Pretty Digital - Wednesday, August 13, 2014

Arid Recovery is not just about the animals. In fact, if it wasn’t for our plants we wouldn’t have our cute bettongs and all the other animals. For this reason, it’s vital that we monitor the health of the vegetation inside the Reserve.

Flora monitoring at Arid Recovery was established right from the start, in 1997, with a range of techniques used to enable us to collect long-term data on vegetation condition, cover and species diversity inside and outside the Reserve. Now, with over 15 years of data, it gives us a great opportunity to begin analysing this data to see if we can determine trends in relation to the effects of our introduced and reintroduced herbivores, and to determine the strongest indicator species for monitoring grazing by herbivores to help trigger management actions when overgrazing occurs.

Recent analysis of this data showed that, while we have an excellent dataset, there are modifications to our monitoring that we can employ in order to get even more out of the data we collect. Over the past few months, Arid Recovery’s Ecologist, Cat Lynch, has been working with our Research Scientist and Craig Baulderstone, who previously worked at South Australia’s Pastoral Board, to further develop Arid Recovery’s flora monitoring program.

It was determined that a number of small quadrats should be set up at each of our sites to provide data on cover of flora species; data which was generally not being picked up through other methods. Craig was recently kind enough to visit Arid Recovery for a week to assist Cat with setting up the new quadrats and collecting data. With his two kids, Mick and Tom, in tow, Craig very enthusiastically trudged the dunes and swales in very hot weather to measure all the saltbush, blue bush, ruby saltbush and other weird and wonderful flora that makes Arid Recovery and the arid zone so unique.

The monitoring event was very successful, with a range of data collected that will assist us with determining the effect that our reintroduced herbivores (i.e. bettongs and stick-nest rats) have on vegetation inside the reserve, as well as the effect that introduced herbivores (i.e. rabbits) have on vegetation outside the Reserve.

We thank Craig very much for volunteering his time to assist Arid Recovery with our flora monitoring program.

Roxby Downs Chirstmas Cavalcade

Pretty Digital - Wednesday, August 13, 2014

Christmas is fast approaching, and what better way to join the Christmas cheer than attending the Roxby Downs Christmas Pageant! On Saturday evening the Roxby Downs community left the cool comfort of their air-conditioned houses and lined the main street in the scorching sun eager to catch a glimpse of Santa as the procession went past.

Arid Recovery entered a float into the pageant, teaming up again with local school St Barbara’s Parish to present ‘Alice in Arid Lands’ with the students wearing their school musical costumes based on the classic adventure story Alice in Wonderland. The children were dressed as different characters from the story, and were led by none other than Macca the Bilby, who had left his burrow early to ensure that he didn’t miss out on any of the fun!

Macca was certainly a highlight for children and adults alike, with the streets coming alive with shrieks of laughter as Macca wiggled his tail and blew kisses to the crowd. Macca even managed to do a few dance moves on the back of Rhino, entertaining the crowd and surprising the Arid Recovery staff that hadn’t seen Macca Bilby that active in a long time.

As the parade finished, Macca returned back to his friends at the Arid Recovery Reserve whilst the rest of us kicked back on the grass at Richardson Place and enjoyed the festivities.

Arid Recovery would like to say a big thank you to the students of St Barbs for decorating the float beautifully in tinsel and beads, and for taking part in the pageant during the evening.  

 

Museum Madness

Pretty Digital - Wednesday, August 13, 2014

The South Australian Museum carefully wrapped specimens and put exhibits in boxes as they headed on the road for the last of their ‘Out of the Glass Case’ roadshow for the year 2013. Roxby Downs was the final destination for the travelling roadshow, and how lucky we were to have these special visitors.

Bringing with them a range of staff with expert knowledge on all areas including birds, spiders, fossils, and geology, the Roxby Downs community was treated to a night of discovery and wonder as the Area School library doors opened to the public for a Twilight Event. Arid Recovery was fortunate to be invited to participate in the Twilight Event, which enabled community members to see educational displays and participate in hands-on learning in a fun environment.

A regular at expos and events, Arid Recovery’s skins and skulls display proved again to be a hit, with many bidding scientists amazed at how light weight an emu’s skull is and how small a cat’s head must be! Visitors to the stall also had the opportunity to touch a range of furs, and distinguished between native and introduced animals by looking at the patterns and colourations on the animal’s coat.

The Arid Recovery office pet, Bruce the juvenile bearded dragon also came along for the evening. Bruce was extremely popular with the children, and his presence made every small child want to share their story about how they saw a lizard in their backyard in Roxby!


Local kids examine the skins and skulls display 

“Opportunities like the Community Twilight Event don’t come by Roxby Downs very often. It was fantastic to see so many members of the local community embracing the evening and bringing the kids down to learn something new and exciting,” explained Anni Walsh, Education and Community Officer. “Visiting these educational displays encourages children to use their imagination, and open their eyes to appreciate the natural wonders of our world.”

Highlights of the evening included blowing into the conical shell ‘trumpet’, witnessing fossils found in the Flinders Ranges region billions of years ago, seeing the egg castings of baby trap door spiders, touching a 10 foot python and of course the 'emu news' puppet show!
