The Green Army have been beating the heat this summer while completing fence upkeep and maintenance. INTRODUCTION Return to the desert for our new GM Exciting times ahead as we enter 2016 with a new General Manager by Kimberley Solly I t is our pleasure to announce that Dr Katherine Tuft will be leading Arid Recovery into a bright future as she takes up the position of General Manager. Katherine joins the Arid Recovery team from the Australian Wildlife Conservancy’s Mornington Wildlife Sanctuary. Katherine held the position of Regional Ecologist in the iconic Kimberley region and will bring great leadership experience from her time as a leader to field ecologists, interns and volunteers. With a background spanning across fields of conservation research, monitoring and management, feral fauna and flora control and engaging with traditional owners, Katherine is well suited to the dynamic role at Arid Recovery. Katherine obtained her PhD in 2010 from the University of Sydney, where she focussed on the foraging ecology of the threatened Brush-tailed Rock-wallaby. Katherine will be settling into the Roxby Downs community with her husband Hugh and two sons. Katherine and Hugh have both previously worked with Arid Recovery so are all too familiar with our vast dunes and furry friends. Katherine will take the helm from our interim General Manager KJ Kovac, who has been involved as a volunteer with Arid Recovery from the very beginning. KJ has made immense strides in her short time as our GM and is deserving of a huge rest after working for 17 years in various roles at Olympic Dam. We thank KJ for all her hard work and dedication to Arid Recovery. 1 Newsletter Issue 1, 2016 RESEARCH Quoll-ified Explorers in the AR Reserve The terrain of the Arid Recovery Reserve adds an extra challenge to radiotracking our quolls by dr rebecca west I n the final week before Christmas we trapped both of the female Western Quolls, Sepia and Koombana, that we introduced to the Reserve in May 2015. This was no small feat as both quolls continue to move and use new bettong warrens or bilby burrows, putting our team’s radiotracking skills to the test to track them down across the undulating dunes (which can block radio signals). Once located we then use internal burrow traps baited with stinky chicken necks (the older the better as far as the quolls are concerned). Both quolls were in excellent condition and kindly provided us with scats in the traps so we can continue to look at their diet. We fitted a lightweight GPS collar to each of the quolls late last year to collect information on their movements across the Reserve. It turns out that one of our quolls, Koombana, is much more of an explorer than the other! Map of movements of our two quolls while they wore the VHF with GPS collar. The circles indicate where the collar took GPS fixes at 9pm, 12 midnight and 3 am over a two week period. Koombana is using a larger home range, which (from shelter site locations as well) does not overlap with Sepia’s. Now we know why it has been so difficult to find Koombana! We also ran an experiment in November to see whether exposure to quolls has influenced the responses of stick-nest rats to predator odours. To run this experiment we had to design special feeding cages, known as ‘ratstaurants’, to stop the bettongs from interfering. We built ratstaurants close to 20 stick-nest rat nests and provided carrot slices with a piece of towel carrying the body scent of either cat, dingo, quoll, mulga snake, rabbit or blank (control). We used remote cameras to film rat behaviour for each trial and we are currently analysing the footage to see whether there are any differences in foraging and vigilance behaviours in rats that have and haven’t had exposure to quolls.

All four re-introduced species have now been inside the reserve for more than 10 years and we were interested to see if they had retained the genetic diversity of the original founders. If genetic diversity has declined then plans may need to be made to add new genes through supplementary reintroduction of new animals. As many threatened species already have low diversity due to their small population size we were keen to ensure we maximized diversity to enable the species to adapt to future events and to reduce extinction risk. Arid Recovery Research Scientist, Katherine Moseby, partnered with PhD student Lauren White and geneticist Jeremy Austin from the University of Adelaide to apply for a grant to undertake this work. Arid Recovery collected new DNA samples from the animals currently inside the Reserve which were compared with DNA originally taken from animals reintroduced many years ago. Lauren White conducted the genetic analysis and interim results suggest that inbreeding is high, a result that is expected because bettongs now only survive in the wild on three DNA samples were taken from bettongs and bandicoots captured in the Reserve in cage traps. Credit: Kimberley Solly islands in Western Australia, thus all remaining animals in the species are closely related. Interestingly however, the Burrowing Bettongs appeared to have retained their genetic diversity over the last 10 years suggesting that we may not need to add new genetic material just yet. We are still awaiting results from the rest of the samples and from the Western Barred Bandicoots so stay tuned for more updates. Thanks to the Nature Foundation of South Australia for providing the much-needed funds to allow this work to be conducted. Snap! Snap! Snap! Can you guess what these two are doing out of bed during daylight? At the Arid Recovery Reserve we use remotely sensed cameras to assist with incursion monitoring. Each time we sit down to review the images we are surprised with what we find. On this occasion a Greater Stick-nest Rat and Burrowing Bettong were caught red handed during daylight outside their nest and burrow, respectively. It turns out they were slurping up water from recent rain off the branches of a dead acacia bush. 3 Newsletter Issue 1, 2016 REport A NN U A L TRAPPING We are gearing up for yet another year of annual trapping; the 17th of the past 18 years! WHY? Planigale gilesi after release. Credit: Aaron Fenner Giles Planigale found at Bon Bon Reserve This is the first record of a Planigale at Bon Bon Reserve by dr aARON FENNER O ver the past few months, two honours students from Flinders University and 15 very keen volunteers have been pitfall trapping small vertebrates on Bush Heritage Australia’s Bon Bon Reserve as part of Arid Recovery and Bush Heritage Australia’s South Australian Rangeland Alliance program. One project they are working on is investigating the effect that Buffel Grass (Cenchrus ciliaris), which has been a declared weed in South Australia since early 2015, has on small vertebrate assemblages. Buffel Grass is an aggressive coloniser and can rapidly alter the landscape by out competing native species and altering fire regimes. In fire sensitive systems such as South Australia’s mulga woodlands, its impact can be devastating turning mulga woodlands into single species grasslands. This project will provide valuable information on the effect Buffel Grass has on small vertebrate assemblages and also provide information on how these assemblages differ in 4 Newsletter Issue 1, 2016 areas which have buffel grass, have had Buffel Grass removed from them (through weed control programs conducted on Bon Bon), and areas where Buffel Grass has not ever been present. The project is still in its early stages and will continue into the new year with the next round of trapping set to happen in late January - early February 2016. To date, 20 lizard species, seven snake species and two mammal species have been captured during the study. Giles Planigale was caught in a pitfall trap while conducting the study. This is the first record of any Planigale on Bon Bon Reserve. Planigales are a carnivorous marsupial in the same family as the quolls, they will eat anything they can take on, including small mammals and lizards. They can be differentiated from the Narrow-nosed Planigale which overlaps in distribution (but yet to be recorded at Bon Bon Reserve) as the Giles Planigale has 2 premolars in each side of both the upper and lower jaw rather than 3. Trapping events occur each year as a way of documenting changes in relative abundances, species assemblages, health and reproductive condition, and longevity. These changes will be compared on either side of the Arid Recovery Reserve’s exclusion fence. who? Annual trapping targets small vertebrates, so our smaller mammals (plains rats and hopping mice) and reptiles. In 2014, 95 mammals and 262 reptiles were assessed. how? We use Elliot traps to catch our small mammlas and pitfall traps to catch reptiles. when? This year the event will be held from March 1st- 5th. If you are interested in volunteering at Arid Recovery for any of our trapping events contact info@aridrecovery.org.au This could be the year that we trap the Kultarr, a species that has been caught on the neighbouring mine lease but not inside the Arid Recovery Reserve! report Green Army getting it done The Roxby Downs Green Army Project must be one of the most unique Green Army Projects in Australia. by adrian friedel F ew 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. The last few weeks of our Project will include 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 and 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. Having the opportunity to get up close and personal to the unique wildlife of the Reserve 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 next Green Army round (20 week Project) starts on the 21st of March. i For more information or to apply, visit http://conservationvolunteers.com.au/green-army/ The Green Army team have been a wonderful help to Arid Recovery, confirming the old saying that many hands make light work! Credit: Adrian Friedel 5 Newsletter Issue 1, 2016 Insight Success for our Quiz Night Our biggest fundraiser for the year was a huge hit by letitia sikora and kimberley solly A rid Recovery hosted a Quiz Night at The Roxby Downs Community Club on Friday 20th November 2015. 116 people across 15 different teams packed out The Club to test their inner genius. We had six rounds including a local Roxby Downs/Arid Recovery round to test the attendee’s knowledge of their own backyard. We were super impressed to see how many locals knew our Big 4 and some even trickier questions about the Arid Recovery Reserve. The enormous turnout and support on the night meant we raised a whopping $1920.35 to go toward our Reserve upgrade. Of course, this fundraiser would not have been possible without the generosity of local businesses and residents who donated to our silent auction and prizes. The Roxby Downs Community Club went above and beyond by sponsoring us by hosting the event, supplying equipment and their hard work in setting up tables. The night was a great success, with very positive feedback. We can’t wait to do it all again! Arid Recovery would like to thank the following local businesses and residents for their generous donations: Aphelion Wine Co Arid Lands Botanic Gardens Auto Pro Bianco Bill Hagger Desert Scents Dublin Meats Laura Trotta Roxbylink Roxby Downs Community Club Roxby Hourglass Jewellers Smokemart Thirsty Camel/ Roxby Downs Tavern William Creek Hotel Winners are grinners. The Negative Nancies were the smartest on the night, taking out the event by half a point!

Held each month throughout the school year, Market Day has been a great way to get local children involved in the environment and Arid Recovery. We have been getting mucky by painting feathers, making nature wreaths, painting landscapes from photographs, decorating holiday cards, and making critters from natural items. A huge thank you to Charisse and Geoff Sanders, Ruth Shepherd, Bec West, the Green Army, Alice Taysom, Natalie Lioulios, David Hunter and Margaret Wyatt for volunteering their time to help out at Market Days. 6 Newsletter Issue 1, 2016 Decorating animal shapes with nature’s gifts.

Volunteers offer a range of skills and are involved in all aspects of Arid Recovery. We have volunteers who assist with administation, community events, feral control or research, and some that assist with all of those tasks! We have volunteer options for short and long-term visitors or residents, so why not come and lend a hand? i If you’d like to get involved and become a volunteer at Arid Recovery please contact info@aridrecovery.org.au Volunteer of the quarter Ruth Shepherd Although occupied for 40+ hours a week working on the ARC Project, Ruth still found time to assist with community outreach and education events. Ruth was an enormous help at Market Days, Buffel Buster working bees and school visits to the Arid Recovery Reserve. Ruth stayed with us for ten weeks and was a valuable volunteer. Our Reserve upgrade is well underway The buildings have been moved to the Reserve and are ready for a makeover by kimberley solly W ith steadily growing research and education visits along with tourism expansions on the horizon, the infrastructure at the Reserve is in need of an upgrade. Aspen Parks Myall Grove in Roxby Downs donated the two new transportable buildings, which includes a classroom, a new kitchen and more bedrooms. We are very thankful to the following businesses for all their help in getting the new buildings to the Reserve: Aspen Parks Myall Grove BSH Coates Hire Monadelphous Engineering Toll As for the future, we are working towards getting the buildings ready for the tour and education season. We will be seeking donations for paint, decking materials, lino, and bunk beds. Our fundraising for a new solar system and plumbing will continue throughout 2016. 7 Newsletter Issue 1, 2016 supporters What better way to contribute to Arid Recovery than sponsoring the fencline that protects our species Sponsor 100m of fenceline - a gift to save our species Your sponsorship includes: • Certificate of sponsorship • 12 month membership to Arid Recovery • Individualised plaque on your segment of fence • A warm and fuzzy feeling knowing that you are contributing to the ongoing work at Arid Recovery i Sponsor 100m of fenceline at www.aridrecovery.org.au/donate Donate Join Donate online or over the phone to assist the work of Arid Recovery.
