Message from the CEO<br />
One of the roles of zoos is to build awareness about conservation<br />
and wildlife, particularly the protection of biodiversity.<br />
2008 was the Year of the Frog, which was a global education<br />
campaign. In addition to the awareness programs at <strong>Perth</strong> <strong>Zoo</strong>,<br />
we commenced a research and breeding program for a local<br />
amphibian, the threatened White-bellied Frog (Geocrinia alba).<br />
For <strong>2009</strong> Year of the Gorilla we have worked with other zoos<br />
on a mobile phone recycling campaign.<br />
Now, to coincide with the birth of a critically endangered<br />
Sumatran Orangutan at the <strong>Zoo</strong>, we are increasing our effort<br />
with the Don’t Palm Us Off campaign, which highlights the<br />
loss of wildlife and habitat as a result of palm oil farming in<br />
South-east Asia.<br />
<strong>Perth</strong> <strong>Zoo</strong> has joined with <strong>Zoo</strong>s Victoria, <strong>Zoo</strong>s South Australia,<br />
Taronga Conservation Society of Australia and Auckland <strong>Zoo</strong> in<br />
this campaign to request that food stuffs which contain palm oil<br />
be labelled so that we can all be aware of a product’s content.<br />
The aims of the campaign are to increase public involvement in<br />
abating the threats to orangutan and other wildlife in South-east<br />
Asia; raise awareness about the impact of consumer decisions<br />
on the environment; and call for food producers to ensure they<br />
use sustainable sources.<br />
People can show their support for the campaign by registering<br />
their details on our website <br />
or by filling in a Don’t Palm Us Off postcard when they visit the<br />
<strong>Zoo</strong>. See the article in this edition of News Paws for more<br />
information about this campaign.<br />
Another article in this News Paws acknowledges one of <strong>Perth</strong><br />
<strong>Zoo</strong>’s much valued partners, the Water Corporation. With<br />
sustainable management of the earth’s resources a shared<br />
objective the Water Corporation and <strong>Perth</strong> <strong>Zoo</strong> have developed<br />
a strong relationship over many years. Their latest contribution,<br />
the <strong>Perth</strong> <strong>Zoo</strong> Conservation Calendar, in conjunction with print<br />
media sponsor The Sunday Times, is yet another great<br />
partnership project.<br />
We could not continue our work without long-term partners such<br />
as the Water Corporation and, on behalf of the whole <strong>Zoo</strong>, we<br />
sincerely appreciate their support.<br />

Ultrasounding<br />
<strong>Perth</strong> <strong>Zoo</strong>’s Botanic Heritage<br />
You’ve heard of ultrasounding<br />
pregnant women to make sure<br />
their unborn child is healthy,<br />
but have you heard of<br />
ultrasounding trees?<br />
<strong>Perth</strong> <strong>Zoo</strong> has kept many plant<br />
species which were originally planted<br />
under the guidance of the <strong>Zoo</strong>’s<br />
head gardener, Harry Steadman,<br />
from 1899–1929. In order to keep<br />
these and other trees healthy, a lot<br />
of work needs to be done by our<br />
present-day horticulturists.<br />
<strong>Perth</strong> <strong>Zoo</strong> horticulturists examine<br />
trees for signs of decay or distress<br />
such as poorly tapered branches,<br />
buckling, loose bark or cracks. This<br />
is especially important when you’re<br />
looking at trees that are over 100<br />
years old and have seen many<br />
seasons, storms and changes.<br />
Internal problems are obviously more<br />
difficult than external ones but that<br />
doesn’t mean they should be<br />
overlooked. This is where ultrasound<br />
comes in.<br />
The PiCus ® machine is just one of<br />
the tools that arborists – or tree<br />
surgeons – use to assess the tree’s<br />
health and whether there is any<br />
internal decay or damage.<br />
Likened to an ultrasound machine,<br />
it provides a non-invasive way to<br />
detect poor health in trees. Sound<br />
waves are transmitted through a<br />
degraded section of the branch or<br />
trunk and a sectioned image, or<br />
tomogram, is produced.<br />
The image is colour-coded and<br />
shows healthy, altered and decayed<br />
woods, allowing the arborist to<br />
determine whether the tree poses<br />
any risk. The limb or section of the<br />
tree is removed if necessary.<br />
“<strong>Perth</strong> <strong>Zoo</strong> is probably the healthiest<br />
park or plant collection I have ever<br />
come across in my 35 years in the<br />
industry,” says <strong>Perth</strong> <strong>Zoo</strong> Horticulture<br />
Curator Andrew Blake.<br />
“I can see two reasons for this: great<br />
plant diversity and the presence of<br />
animals. These are also the reasons<br />
for the good health found in<br />
undisturbed bush areas.<br />
“This means our botanic collection is<br />
in such good health that the trees<br />

machine. Right: Bowden Tree Consultant<br />

Consultancy.<br />
live longer than in many other parks<br />
and gardens. Just like elderly people<br />
or animals, old trees can have trouble<br />
with strength in their limbs or being<br />
affected by extremes such as storms<br />
and being knocked so they require<br />
careful management. Tomograms are<br />
another tool in helping us keep the<br />
<strong>Zoo</strong>’s botanic collection healthy.”<br />
If a branch needs to be removed,<br />
that doesn’t mean it’s no longer<br />
useful. <strong>Perth</strong> <strong>Zoo</strong> keepers are always<br />
on the hunt for branches that can be<br />
used in exhibits as behavioural<br />
enrichment, to help stimulate<br />
climbing, curiosity and other natural<br />
behaviours in their animals.<br />
“Whenever we’re pruning and have to<br />
remove a limb we need to be careful<br />
not to cut it up too quickly. The<br />
keepers are always looking for ‘exhibit<br />
furniture’ and often need a branch that<br />
is shaped ‘just so’,” says Mr Blake.<br />
So what is the result of our<br />
horticulturists’ hard work? The great<br />
ambiance and feeling of immersion<br />
you experience when you walk into<br />
one of the <strong>Zoo</strong>’s geographical zones<br />
and see plants that reflect the native<br />
vegetation of an African savannah,<br />
native Australian bushland or Asian<br />
rainforest, as well as some very<br />
healthy animals.<br />

In the Field<br />
<strong>Perth</strong> <strong>Zoo</strong> and its staff are committed to the conservation of species in their natural habitats. Field work is<br />
an important part of any conservation project working with animals in the wild. Here is a case file through<br />
the eyes of one of our staff members.<br />
Christmas Island<br />
Reptile Collection<br />
22 August to 5 September <strong>2009</strong><br />
Location: Christmas Island<br />
<strong>Perth</strong> <strong>Zoo</strong> Field Workers: Helen Robertson<br />
(Animal Health and Research Director),<br />
Simone Vitali (Senior Veterinarian) and<br />
Meagan McPharlin (Australian Fauna Supervisor).<br />
About Christmas Island<br />
Christmas Island is located off the coast of Java,<br />
Indonesia. It has been an external territory of the Australian<br />
Commonwealth since 1958. With its tropical climate, the<br />
temperature is 27–29°C during the day and 24°C at night,<br />
all year round.<br />
The majority of the island is a national park. Habitat<br />
destruction (due to land clearance from mining and other<br />
human activities) and introduced species have resulted in<br />
an ecological shift that has seen several species become<br />
extinct.<br />
Background<br />
A dramatic fall in native reptile numbers has occurred on<br />
Christmas Island. Five endemic species – Lister’s Gecko,<br />
the Blue-tailed Skink, the Forest Skink, the Giant Gecko<br />
and the Christmas Island Blind Snake – are found on the<br />
island. They compete for food and shelter with five<br />
introduced species: the Asian House Gecko, Barking<br />
House Gecko, Grass Skink, Flowerpot Blind Snake and<br />
Asian Wolf Snake.<br />
Blue-tailed Skinks (Cryptoblepharus egeriae) and Forest<br />
Skinks (Emoia nativitatus) were once commonly found<br />
across the island, however, both appear now highly to a<br />
small area on the island. Blue-tailed Skinks have gone from<br />
being one of the most conspicuous and abundant reptiles<br />
Blue-tailed Skink.<br />
on the island to being only found in very few locations and<br />
in small numbers.<br />
Similarly, Forest Skinks were also once more common on<br />
the island but now it is difficult to find more than one in<br />
each survey attempt.<br />
This dire state prompted the Australian Government to<br />
initiate a captive breeding program to ensure the survival of<br />
these two species. <strong>Perth</strong> <strong>Zoo</strong> was approached because of<br />
its experience and success in breeding Lancelin Island<br />
Skinks for release. In conjunction with the Western<br />
Australian Department of Environment and Conservation,<br />
152 of the critically endangered skinks were bred at the<br />
<strong>Zoo</strong> and released onto Favourite Island. The program is<br />
considered a success.<br />
With this background knowledge, <strong>Perth</strong> <strong>Zoo</strong> staff travelled<br />
to Christmas Island in August and September to work with<br />
Parks Australia staff on Christmas Island to collect the<br />
founder animals for the skink breeding programs. They<br />
also helped draft husbandry manuals for the skinks’ care.<br />
Goals<br />
The first goal was to work with Parks Australia staff to<br />
collect and house 40 Forest Skinks and 40 Blue-tailed<br />
Skinks. Due to the fall of numbers in the wild, it is hoped<br />
insurance populations will be established both on and off<br />
the island.<br />
Later, it is hoped the skinks will form part of a breed-forrelease<br />
program. At the moment, however, the focus is on<br />
establishing insurance populations, researching the skinks’<br />
biology and investigating and addressing threatening<br />
processes.<br />
Process<br />
Forest Skink.<br />
Working with park staff, one day Simone and Helen<br />
focused on the Blue-tailed Skink while I (Meagan) tried to<br />
locate Forest Skinks. We found two previously unknown<br />
locations in the area where park staff had previously been<br />
detecting and capturing skinks. These were found on
Rough terrain in which the field work was completed.<br />
pinnacle rocks, a skink favourite because of the rocks’<br />
hollow, labyrinth-like nature which give the skinks plenty of<br />
places to hide.<br />
We collected the skinks into carry packs containing soil<br />
and leaf litter in which they could hide. At the end of the<br />
day we trekked back to the vehicle then drove back to<br />
base camp with the skinks.<br />
All of the skinks were weighed, measured and checked<br />
for any physical abnormalities. Faecal samples were taken,<br />
if possible, to be later checked for parasites. All skinks<br />
collected so far appear to be in excellent health.<br />
For now skinks are being kept by park staff in enclosures<br />
designed and constructed by park staff inside a modified<br />
gazebo on Christmas Island until a long-term option can<br />
be established. Here the animals are exposed to natural<br />
sunlight and the humid, local climate. We also helped<br />
construct artificial habitats for the Forest Skinks to replicate<br />
their complex habitat within pinnacle rocks.<br />
During our trip we collected 17 Blue-tailed Skinks and one<br />
Forest Skink. Since returning to <strong>Perth</strong> <strong>Zoo</strong>, Christmas<br />
Island Park staff have collected a further 21 Blue-tailed<br />
Skinks and another Forest Skink. Finding so few Forest<br />
Skinks is of concern.<br />
Meagan and Helen collect data.<br />
Highlights<br />
I work very closely with<br />
reptiles at <strong>Perth</strong> <strong>Zoo</strong> so<br />
working with skinks in the<br />
wild was very rewarding.<br />
I was very excited when<br />
I found the two new<br />
locations for the Forest<br />
Skinks were found. I<br />
approached the challenge<br />
with the mentality of ‘If I was<br />
a skink, where would I be?’<br />
Challenges<br />
Sheltered facility to house the SKinks.<br />
Simone and Helen complete health<br />
checks on Skinks.<br />
The skinks are usually found in habitats with very rough<br />
terrain – pandanus vegetation with sharp pinnacle rock<br />
cliffs with a drop into the sea on one side. Pandanus has<br />
serrated leaves, so I had to tend to leg and arm scratches<br />
more than once. Also, the humidity meant that wherever<br />
we went we had to carry plenty of water and my clothes<br />
clung to me.<br />
Benefits<br />
I value being involved with in situ conservation, and<br />
providing knowledge and experience that will improve the<br />
success of the program. Contributing to the initial stages<br />
of planning, brainstorming and implementation meant I<br />
developed problem solving skills and applied the<br />
knowledge I’ve learnt at <strong>Perth</strong> <strong>Zoo</strong> to the wild. The<br />
husbandry for the skinks was developed using a<br />
combination of our and park staff knowledge of similar<br />
species because so little is known about the ecology of<br />
Christmas Island skinks. This meant a huge learning curve<br />
but I love learning new things.<br />
Working with Helen and Simone, who are experienced<br />
professionals, and being able to learn from their vast<br />
experience was also rewarding. I enjoyed the sensory<br />
overload: being in a new place, meeting new people,<br />
adjusting to new animals and the challenges of trekking<br />
through the habitat and adjusting to the climate.<br />

An Otter Romance<br />
at <strong>Perth</strong> <strong>Zoo</strong><br />
The arrival of two Asian Small-clawed Otters has<br />
brought romance to <strong>Perth</strong> <strong>Zoo</strong> as they explore their<br />
new Asian Rainforest home together.<br />
The two otters are part of a regional breeding<br />
program which aims to maintain a sustainable<br />
captive population of this species. Their arrival<br />
coincided with the opening of the new otter exhibit.<br />
Eight-year-old male, Kiet (meaning honourable in Thai),<br />
came from Singapore <strong>Zoo</strong> while nine-year-old female,<br />
Tola (meaning October in Cambodian), came from<br />
Mogo <strong>Zoo</strong>, NSW.<br />
<strong>Perth</strong> <strong>Zoo</strong> Director of Life Sciences Maria Finnigan said<br />
their first introduction to each other went very well and<br />
they’ve been inseparable since.<br />
Visitors can enjoy watching the highly<br />
playful otters dive in and out of the water<br />
and use their highly dexterous front paws<br />
to play with pebbles and handle food.<br />
“It appears to be a promising start as they are getting on<br />
very well. Since their recent introduction they have been<br />
exploring their new home and establishing their territory<br />
together,” Ms Finnigan said.<br />
Staff are hoping that it won’t be long before they produce<br />
pups. It has been 15 years since otters were born at <strong>Perth</strong><br />
<strong>Zoo</strong>. Those three offspring – males Hari and Sook and<br />
female Tulia – are still at the <strong>Zoo</strong> today but, as they were<br />
siblings, were not part of a breeding program.<br />
“Otters usually give birth to two young although up to five<br />
is possible. The new exhibit is designed to house up to 16<br />
otters in total,” Ms Finnigan said.<br />
“Formerly housing Sulawesi Crested Macaques, the new<br />
otter exhibit has been redesigned and refurbished<br />
newspaw s | <strong>Summer</strong> <strong>2009</strong>/10<br />
especially for otters. <strong>Perth</strong> <strong>Zoo</strong> staff who work with this<br />
species have an intimate knowledge of what they require<br />
and the staff led and implemented the exhibit upgrade.<br />
Having these people involved in the design and<br />
construction of the exhibit means the animals are given the<br />
best home possible.”<br />
The result is a sun-dappled rainforest exhibit complete with<br />
lush undergrowth, shade, nooks and crannies, waterfalls<br />
and a pool that will keep the otters stimulated. Asian<br />
Small-clawed Otters are the most terrestrial (land-based) of<br />
the 13 otter species, although they are excellent swimmers<br />
and often catch their food while swimming.<br />
Visitors can enjoy watching the highly playful otters dive in<br />
and out of the water and use their highly dexterous front<br />
paws to play with pebbles and handle food.<br />
Otters in the wild are reliant on clean and healthy water<br />
bodies. Pesticides and other chemicals can flow into rivers<br />
and streams, affecting their food supply and water quality.<br />
The destruction of forests also affects the otters’ food<br />
supply and breeding grounds.<br />
Another feature of the exhibit is a nest box where visitors<br />
can see the otters rest after periods of activity or use to<br />
raise their young. Four life-sized otter sculptures are also<br />
included at the exhibit and provide a great photo<br />
opportunity for visitors.<br />
Tola and Kiet are now on display in the Asian Rainforest<br />
opposite the Nepalese Red Panda exhibit. The three<br />
sibling otters can still be seen in their usual exhibit with<br />
the underwater viewing bay.<br />
Did You Know?<br />
The female Asian Small-clawed Otter rules the roost<br />
and the male hunts for her and the pups as they<br />
develop.
New Quokka<br />
Breeding Program<br />
Quokkas are once again on display at <strong>Perth</strong> <strong>Zoo</strong> and<br />
they’re here as part of a new nationwide captive<br />
breeding population for the unique marsupial.<br />
<strong>Perth</strong> <strong>Zoo</strong> is leading a program to establish a new<br />
breeding population of Quokkas, working with the<br />
Rottnest Island Authority, Department of Environment and<br />
Conservation and four other Australian zoos. The intent of<br />
the program is to help guard against a decline in Quokka<br />
numbers in the event of disease introduction or natural<br />
disaster. The zoos will also gain valuable insight into the<br />
husbandry and reproductive biology of this species.<br />
So far 15 Quokkas have been moved to the mainland<br />
from Rottnest Island with eight settling into <strong>Perth</strong> <strong>Zoo</strong>.<br />
The Quokkas were selected based on their age, sex and<br />
health and were collected from a number of sites around<br />
the island. Prior to the Quokkas’ departure Aboriginal<br />
Elders performed a traditional smoking ceremony which<br />
farewelled the animals and demonstrated honour and<br />
respect to their ancestors.<br />
In total, 33 Quokkas (five males and 28 females) will help<br />
establish the new breeding population at <strong>Perth</strong> <strong>Zoo</strong>,<br />
Taronga <strong>Zoo</strong>, Melbourne <strong>Zoo</strong>, Gorge Wildlife Park and<br />
Adelaide <strong>Zoo</strong>.<br />
Classified as vulnerable, Quokkas were once abundant on<br />
the Australian mainland but with the arrival of foxes in the<br />
late 1800s their numbers were drastically reduced.<br />
The Quokkas on Rottnest Island are genetically distinct<br />
from the two other Quokka populations in Western<br />
Australia on Bald Island and in Bunbury. Their isolation<br />
means there is a risk of a disease or similar catastrophe<br />
on the island that could affect the population. Maintaining<br />
a captive population in Australian zoos will help guard<br />
against this.<br />

Did You Know?<br />
Rottnest Island got its name from the Quokkas that<br />
inhabit it. Dutch explorer Willem de Vlamingh visited<br />
the island in 1696 and upon seeing the plentiful<br />
Quokkas, which he described as ‘a kind of rat as big<br />
as a common cat’, named the island ‘Rotte Nest’<br />
meaning rat’s nest.<br />

Puteri’s Princess<br />
At 10:40 am on 20 October, <strong>Perth</strong> <strong>Zoo</strong> welcomed its<br />
27th Sumatran Orangutan, Teliti (Indonesian for to be<br />
careful and thorough) into the world as part of its worldrenowned<br />
breeding program.<br />
Weighing just 1.6 kg, female Teliti was born to 39-year-old<br />
female Puteri (Indonesian for princess) who was the first<br />
Sumatran Orangutan born at <strong>Perth</strong> <strong>Zoo</strong> in 1970. She is<br />
also the mother of Temara, the first zoo-born orangutan to<br />
be released into the wild in the protected Bukit Tigapuluh<br />
National Park in Indonesia as part of an orangutan<br />
reintroduction program.<br />
Teliti and Temara’s father is 34-year-old Hsing Hsing who<br />
has been at the <strong>Zoo</strong> for 26 years. He has fathered four<br />
orangutans since coming to <strong>Perth</strong> <strong>Zoo</strong> from Singapore in<br />
1983.<br />
As with the <strong>Zoo</strong>’s pregnant orangutans in the past, keepers<br />
use a standard human pregnancy kit to determine<br />
pregnancy. Puteri was confirmed pregnant in May this year<br />
and the birth has been eagerly anticipated ever since.<br />
<strong>Perth</strong> <strong>Zoo</strong> Exotic Mammals Curator Leif Cocks says the<br />
pregnancy went extremely well and the birth was very<br />
quick and hassle-free.<br />
“Puteri adores Teliti, cradling and feeding her when she is<br />
hungry or appears to need reassurance,”<br />
Mr Cocks said.<br />
“Teliti is hanging onto Puteri without assistance and<br />
is strong and alert which are all good indicators of a very<br />
healthy, young orangutan.”<br />
Teliti will start eating some solid foods, such as tropical<br />
fruit, at about five months of age but will continue to<br />
suckle for the next five to six years. She is the third<br />
orangutan born at the <strong>Zoo</strong> over the past five years.<br />
With the success of reintroducing Temara into the wild,<br />
<strong>Perth</strong> <strong>Zoo</strong> has had a positive<br />
response to the Don’t Palm Us Off<br />
advocacy campaign, however<br />
more signatures are needed.<br />
Don’t Palm Us Off aims to change<br />
food-labelling legislation in Australia<br />
and New Zealand, mandating the<br />
labelling of palm oil on all food<br />
products.<br />
But why is this an issue?<br />
Approximately 6,000 orangutans are<br />
killed each year, mostly due to the<br />
destruction of their habitat. The primary<br />
reason for this is the increasing<br />
demand for oil palm plantations which<br />
results in large-scale clearing of<br />
rainforests in Indonesia and Malaysia.<br />
Currently, palm oil can simply be<br />
labelled as vegetable oil and is found<br />

successful breeding programs like that at <strong>Perth</strong> <strong>Zoo</strong><br />
assists with the re-establishment of extinct populations<br />
of Sumatran Orangutans in protected areas.<br />
Teliti was named by nine-year-old Calvin den Boer in a<br />
competition run with .<br />
Come and see Puteri and her precious daughter in<br />
the Sumatran Orangutan exhibit, located in the<br />
Asian Rainforest.<br />
in a wide variety of products including<br />
chocolate, bread, detergents and<br />
cosmetics. This means you don’t<br />
know if you’re buying products that<br />
contain palm oil.<br />
Food Standards Australia New<br />
Zealand (FSANZ) has the power to<br />
change food-labelling legislation.<br />
However, in order to justify this change<br />
FSANZ needs to know that you want<br />
the right to choose. That’s why we<br />
want to hear from you.<br />
Once palm oil is clearly labelled, we<br />
can seek to have tighter regulation of<br />
the palm oil industry and drive the<br />
demand for sustainable palm oil which<br />
doesn’t lead to the destruction of<br />
rainforests, the deaths of orangutans<br />
and other animals or the exploitation<br />
of workers.<br />

with a new heated billabong and feeding platform<br />
with masses of plants and rock to replicate the<br />
Kimberley region of Western Australia.<br />
Since its opening on 26 September by Minister<br />
for the Environment Donna Faragher, the exhibit<br />
has proved to be very popular with visitors,<br />
especially during Croctober (the month formerly<br />
known as October). Visitors are able to watch<br />
Simmo from a 12 metre long glass viewing area.<br />
During the summer months, one of the most<br />
spectacular sights for visitors will be Simmo’s<br />
Sunday feed.<br />

While standing on the new feeding platform, keepers can<br />
now feed Simmo in full view of visitors and watch as he<br />
propels his body out of the water to catch his meal.<br />
Crocodiles use this behaviour to launch a surprise attack<br />
on their prey.<br />
Taking advantage of our warm summer, Simmo can also<br />
be seen basking in the sunlight, which he used to do in an<br />
out-of-sight area. Crocodiles bask in the sun to heat and<br />
cool their bodies to maintain a steady temperature of<br />
30–32°C. The process, which is common to ectotherms<br />
(a group of animals that includes reptiles and amphibians),<br />
is known as thermoregulation.<br />
Simmo also thermoregulates in his new outdoor billabong.<br />
It holds 90,000 litres of water that is warmed to 28°C.<br />
It is 1.7 m deep at the lowest point and the water is<br />
exchanged and filtered every 24 hours to keep Simmo<br />
healthy and the pool clean.<br />
So how did the new exhibit come together,<br />
and what was involved?<br />
Building zoo exhibits takes into account everything from<br />
animal husbandry and welfare, visitor safety, occupational<br />
health and safety for staff and interpretation and education.<br />
This requires collaboration from many different areas<br />
across the <strong>Zoo</strong> including zoo keepers, horticulturalists,<br />
educators, graphic designers and maintenance staff. Of<br />
course, builders are also needed for the bigger works,<br />
such as pool construction and fencing.<br />
The main idea behind the look and feel of the exhibit is to<br />
replicate the Kimberley region, one of the Estuarine<br />
Crocodile’s natural habitats. To achieve this, a lot of<br />
planning went into the choice of plants and trees for<br />
the gardens by the <strong>Zoo</strong>’s horticulture team.<br />
<strong>Perth</strong> <strong>Zoo</strong> horticulturist Tanya Taylor says that the role<br />
of the horticulturist goes far beyond simply planting<br />
the flora species.<br />
“During the planning process for exhibits we have to<br />
research the plants endemic to the animal’s<br />
distribution in order to replicate their natural habitat,”<br />
Ms Taylor says.<br />
newspaw s | <strong>Summer</strong> <strong>2009</strong>/10<br />
“Often there is up to a year’s worth of preparation to<br />
grow and source stock that coordinates with the rest of<br />
the project, especially if you want the surrounding<br />
gardens to look more established.<br />
“It’s amazing working on such a huge project like this<br />
because it can involve anything from small seedlings to<br />
huge 200 litre trees. Though it’s hard work it’s very<br />
rewarding to see the finished product with everything<br />
working together.”<br />
Species planted include Pandanus Grasses (Pandanus<br />
spiralis), Gymaea Lilies (Doryanthus excelsa), Pennywort<br />
(Centella asiatica), several species of Melaleucas (also<br />
known as Paperbarks) and a selection of rushes, which<br />
resemble grasses.<br />
By seeing Simmo swimming and out in<br />
the open, visitors get a real understanding<br />
of this powerful and ancient predator.<br />
Another feature of the Kimberley region is the red rocky<br />
outcrops which feature so prominently in this part of<br />
Western Australia. Of course, we had to have the same<br />
at <strong>Perth</strong> <strong>Zoo</strong>. A rock escarpment backdrop was added to<br />
the back of the exhibit as well as along the footpath, and<br />
around the viewing window, billabong and feeding<br />
platform.<br />
Concept Design Management Studio (CDM) co-designed<br />
and completed this rock facade, using a mould of natural<br />
cliff faces. Mesh-covered steel frames in the shape of the<br />
Can you find the 25 Cane Toads and two very<br />
realistic Olive Python models hidden in the gardens<br />
surrounding Simmo’s new exhibit?<br />
Unfortunately Cane Toads are now starting to enter<br />
into northern Western Australia from the Northern<br />
Territory. Many people and organisations are working<br />
hard to stop them from becoming a major menace in<br />
Western Australia.
cliffs were placed around the exhibit. A cement mixture,<br />
which was pre-tinted with terracotta oxide and milled<br />
fibreglass for added strength, was then poured over the<br />
frames and allowed to dry. Rock-covered areas on the<br />
feeding platform, escarpment and around the billabong<br />
were rubberised to protect Simmo’s soft underbelly and<br />
snout.<br />
Other aspects of the project included where to put the<br />
billabong and how to shape it; installation of the viewing<br />
glass and fences; connecting electricity, sewerage and<br />
water; laying (and mowing) the grass; installing<br />
reticulation and putting down mulch; and writing,<br />
designing and installing interpretative panels.<br />
Australian Fauna Curator John Lemon says the finished<br />
exhibit not only showcases the apex predator of the<br />
Kimberley escarpment but it also enables visitors to delve<br />
into Simmo’s world.<br />
“Simmo came to <strong>Perth</strong> <strong>Zoo</strong> in 1998 from Darwin and has<br />
held a fascination for our visitors since, especially children,”<br />
Mr Lemon said.<br />
“The redevelopment affords visitors the opportunity to<br />
see Simmo’s distinct behaviours. By seeing Simmo<br />
swimming and out in the open, visitors get a real under -<br />
standing of this powerful and ancient predator; and I’m<br />
certain visitors will get a thrill seeing Simmo launching out<br />
of the water to grab his Sunday feed during summer.<br />
“Hopefully people will now trust us when we say, ‘Yes,<br />
he is real’.”<br />
Our crocodile’s statistics<br />
Age: Between 50 and 70 years old<br />
Length: 4.7 m<br />
Weight: About 500 kg<br />
Relationship status: Single. Simmo can’t be housed<br />
with female crocodiles as he’s killed two in the past<br />
before he came to <strong>Perth</strong> <strong>Zoo</strong><br />
…Now that’s a heavyweight!<br />
Spotlight on the Plants<br />
of the Kimberley<br />
Rushes and Sedges<br />
Rushes are small grass-like shrubs that are angiosperms<br />
(flowering plants). They are often found in dry conditions<br />
where there is little water or nutrients in the soil. Sedges<br />
are similar in appearance to rushes. Both types of plant<br />
serve as ground cover in the exhibit.<br />
Pandanus Grass Pandanus spiralis<br />
Also known as a Screw Spine this shrub can grow up to<br />
10 m high and is common in the far north of Australia. Its<br />
spined leaves form a spiral and can be used for weaving<br />
baskets and mats.<br />
Gymea Lily Doryanthus excelsa<br />
This stunning plant has clusters of crimson flowers that<br />
grow on stems reaching up to six metres high and long<br />
sword-like leaves.<br />
Gotu Kola or Pennywort Centella asiatica<br />
Known as Gotu Kola in Sri Lanka, this plant is native<br />
to the far north of Australia as well as India, Indonesia,<br />
Malaysia, Papua New Guinea and other parts of Asia. It<br />
has round, heart-shaped leaves similar to a native violet.<br />
Melaleucas or Paperbarks<br />
Melaleucas are small to large shrubs and trees that are<br />
quite hardy and well-adapted to saline-rich and nutrientdeficient<br />
soils. They have bright, attractive flowers that<br />
are usually white, yellow, pink or red.<br />

<strong>Perth</strong> <strong>Zoo</strong>’s Puggles<br />
<strong>Perth</strong> <strong>Zoo</strong> has had another successful year of echidna<br />
breeding with the birth of two puggles in August.<br />
Moa, meaning ‘three’, and Kain, meaning ‘one’, are the<br />
fourth and fifth puggles bred since 2007. Moa is the third<br />
offspring for female Kiltah and male Wilgi, while Kain is the<br />
first for female Elyan and male Wilki.<br />
<strong>Perth</strong> <strong>Zoo</strong> Australian Fauna supervisor Arthur Ferguson<br />
says both puggles are developing very well under the care<br />
of their mothers in the nursery burrows and are expected<br />
to emerge in February.<br />
Only 13 echidnas have been born in captivity in Australia<br />
and <strong>Perth</strong> <strong>Zoo</strong> is proud to have produced five of them.<br />
Echidnas have typically been difficult to breed in captivity<br />
but <strong>Perth</strong> <strong>Zoo</strong>’s investigation of their breeding habits has<br />
led to a greater understanding of echidna reproduction.<br />
Research indicates that temperature plays an important<br />
role in many stages of the breeding cycles, from<br />
producing the egg and incubating it, to keeping the<br />
puggle safe and developing well in the burrow.<br />
It is very difficult to determine the sex of young echidnas<br />
and so <strong>Perth</strong> <strong>Zoo</strong> has approached Dr Frank Grützner, an<br />
Australian Research Council Research Fellow and geneticist<br />
from the University of Adelaide, for his assistance.<br />
newspaw s | <strong>Summer</strong> <strong>2009</strong>/10<br />
Using a small hair sample from three of the echidnas born<br />
at the <strong>Zoo</strong> (Jilba, born 2007, and Mila and Chindi, born<br />
2008), it is hoped Dr Grützner will be able to determine<br />
their sex.<br />
Dr Grützner investigates the amazingly complex sex<br />
chromosomes of platypuses and echidnas. Dr Grützner’s<br />
research team has identified DNA that occurs only in male<br />
echidnas. Very sensitive genetic tests will be carried out<br />
on Jilba, Mila and Chindi’s DNA in the hair samples to see<br />
if they carry the male-specific DNA.<br />
Moa and Kain must wait until they are eight months old<br />
before they can be sexed using this technique.<br />
Determining the sex of the <strong>Zoo</strong>-born echidnas will help<br />
<strong>Perth</strong> <strong>Zoo</strong> decide who is to be paired with whom in the<br />
breeding season to come. <strong>Perth</strong> <strong>Zoo</strong> hopes to produce a<br />
second generation of captive born echidnas, something<br />
that has never been achieved previously. <strong>Perth</strong> <strong>Zoo</strong> staff<br />
are eagerly awaiting Dr Grützner’s results but until then<br />
they are enjoying watching the two new puggles grow.<br />

A Day in the Life of…<br />
Cassandra Bynder, Native Species Breeding Program Cadet<br />
Cassandra started working at <strong>Perth</strong><br />
<strong>Zoo</strong> as an Indigenous cadet in<br />
February <strong>2009</strong> to help find her<br />
calling in animal conservation.<br />
First starting in the Education section,<br />
Cassandra found it useful to learn<br />
how to educate and communicate<br />
conservation messages to people.<br />
She started with some of <strong>Perth</strong> <strong>Zoo</strong>’s<br />
learning experiences and worked side<br />
by side with other members of the<br />
<strong>Zoo</strong> Education team.<br />
In September, Cassandra moved to<br />
the <strong>Zoo</strong>’s Native Species Breeding<br />
Program (NSBP), which works with<br />
some of Western Australia’s most<br />
threatened species.<br />
“The switch was hard at first but only<br />
because I had to adjust my working<br />
hours to arrive at 7:30 am. I also had<br />
A Day in Cassandra’s Diary<br />
7:30 am Arrive at the <strong>Zoo</strong> and join the NSBP staff for their<br />
morning stretches. They are designed to keep you limber<br />
and help with the day’s activities. It’s also the time to find out<br />
what’s going on with the animals. I then wait to hear which<br />
keeper has the busiest day so I can help them. The Western<br />
Swamp Tortoise round is usually the busiest.<br />
8:30 am We check on the Western Swamp Tortoise<br />
hatchlings in the off-display holding ponds to make sure they<br />
are healthy. We have to keep an eye out for any females that<br />
look as if they are about to lay their eggs throughout the day<br />
so we can monitor them.<br />
8:45 am We walk down to the Australian Wetlands exhibit<br />
to check the water temperature because Western Swamp<br />
Tortoises need a temperature of 14–30°C. We also clean the<br />
glass and remove any excrement or uneaten food from the<br />
tank.<br />
9:00 am We go back to the Western Swamp Tortoise area<br />
and clean the hatchling ponds, while also giving them a feed<br />
of brine shrimp and blood worms.<br />
9:30 am Any weighing and monitoring is done. We also check<br />
the health of the tortoises to make sure there isn’t anything<br />
out of the ordinary.<br />
10:00 am Break for morning tea.<br />
10:30 am I complete odd jobs around the off-display<br />
hatchling and adult holding ponds such as cutting the grass<br />
in the ponds or cleaning out yesterday’s uneaten food.<br />
12:30 pm Lunch.<br />
1:00 pm I go and do some ‘termite harvesting’ for the<br />
Numbats in residence. Basically, I have to separate the<br />
termites from the wood by knocking them into a tray.<br />
This can be very time consuming because adult Numbats<br />
eat 20,000 of these little critters per day.<br />
to acclimatise to a work day where<br />
I’m always on the move but it’s great<br />
because I’m honing a different set of<br />
skills,” says Cassandra.<br />
“I get to be around Numbats,<br />
Western Swamp Tortoises, Dibblers,<br />
Woylies and native frogs all day,<br />
which is great. I provide support to<br />
the keepers, following whoever has<br />
the most to do on that day and doing<br />
food preparation for the animals,<br />
cleaning exhibits, weighing animals<br />
and anything else they need.<br />
“Watching the first Western Swamp<br />
Tortoises egg-laying for the season<br />
(October–November) was amazing.<br />
We know when they are about to lay<br />
because they tend to circle around<br />
sanded areas. If they start to dig a<br />
hole, then we know it’s going to<br />
happen really soon.”<br />
Undertaking the cadetship has<br />
allowed Cassandra to gain insight into<br />
career opportunities.<br />
“When I first started looking into doing<br />
a cadetship at <strong>Perth</strong> <strong>Zoo</strong>, all I knew<br />
was that I wanted to help with<br />
conservation. Working in different<br />
parts of the <strong>Zoo</strong> has allowed me to<br />
gain practical experience for my<br />
Environmental Science course at<br />
Central TAFE and see what is on offer<br />
in this field.<br />
“I’m fascinated by how the different<br />
sections operate and what a day’s<br />
work in each consists of. I’m lucky to<br />
have the opportunity to work in a<br />
variety of positions in a dynamic work<br />
environment, which broadens my<br />
horizons.”<br />
1:30 pm I prepare the food for the juvenile and adult Western<br />
Swamp Tortoises, cutting their ‘pudding’ (an assortment of<br />
beef heart, rat, fish and marron) according to how many<br />
individuals are in each of the 42 ponds.<br />
2:30 pm The tortoises are fed and we head back to the<br />
Australian Wetlands exhibit to give the tortoises their food.<br />
We also check the temperature again.<br />
3:15 pm Wind up for the day: make sure everything is done,<br />
wash up food preparation materials and clean, and check the<br />
temperatures in the holding ponds again. I also help write the<br />
daily report including the temperatures that we’ve taken, the<br />
results of weighing the tortoises, notes regarding their heath<br />
and any important information needed for the next day’s<br />
keeper.<br />
4:00 pm Time to go home and study.<br />

New Ghostly Arrivals<br />
Born on 27 October and 2<br />
November, two Ghost Bat pups<br />
have joined the colony in the<br />
Nocturnal House.<br />
<strong>Perth</strong> <strong>Zoo</strong> received its first Ghost<br />
Bats in 1977 from the isolated Pilbara<br />
population, making <strong>Perth</strong> <strong>Zoo</strong> the<br />
only institution to hold bats of this<br />
origin. Ghost Bats inhabit northern<br />
Western Australia, Northern Territory<br />
and Queensland.<br />
This breeding season, <strong>Perth</strong> <strong>Zoo</strong> staff<br />
discovered something new. The<br />
gestation period for the Ghost Bat is<br />
actually a lot longer than previously<br />
documented, being at least 99–105<br />
days rather than 77–84 days. This<br />
allowed staff to increase the diet of<br />
the pregnant female to accommodate<br />
the young, and closly observe her<br />
toward the end of gestation.<br />
<strong>Perth</strong> <strong>Zoo</strong> staff worked hard to<br />
provide the right conditions for<br />
breeding, which includes an ideal<br />
cave temperature of 27–29°C and<br />
ensuring male and female bats are<br />
paired in time for the breeding<br />
season between May and August.<br />
Once they have mated, the sexes are<br />
separated into two exhibits.<br />
“They are a territorial species and it’s<br />
important to provide an area for the<br />
weaned infants so they can gain<br />
independence and avoid competition<br />
between older males while they are<br />
still maturing,” says Australian Fauna<br />
keeper Michael Cranley.<br />
“It’s the first time in many years that<br />
we’ve had two offspring in one<br />
breeding season. Next year, cameras<br />
will be set up to more accurately<br />
pinpoint their mating habits. Maybe<br />
we’ll even capture a birth on film.”<br />
At the moment the sex of the two<br />
Ghost Bat pups cannot be easily<br />
determined. It is not until they reach<br />
about two years of age that it<br />
becomes easier to tell male and<br />
female Ghost Bats apart. The pups<br />
will start flying at seven weeks of age<br />
and will be weaned at about five<br />
months of age.<br />
Ghost Bats are named for their pale<br />
appearance and the ghost-like<br />
silhouette they make against the<br />
moon as they fly. Large colonies of<br />
bats, once numbering more than a<br />
thousand, inhabit the sandstone cliffs,<br />
abandoned mines and deep limestone<br />
caves of northern Australia. Now the<br />
largest colonies only include about<br />
200 Ghost Bats.<br />
Classified as a vulnerable species,<br />
there are only about 5,000 Ghost Bats<br />
left in the wild due to changes in<br />
habitat and the destruction of the<br />
caves and mine shafts in which the<br />
bats live.<br />
You can make a home for bats by<br />
building or buying a bat box and<br />
installing it on your property. Australia<br />
is home to over 90 bat species and<br />
many have adapted to urban living by<br />
roosting in human-made structures<br />
such as buildings, garages and sheds.<br />
If you don’t mind having a resident bat<br />
in your garage or shed, ensure there is<br />
a clear flight path by removing any<br />
overhanging branches or wire. Visit<br />
<br />
for more information on how to make<br />
your garden bat-friendly.<br />
Did You Know?<br />
The Ghost Bat is Australia’s only carnivorous bat and, like other bats, uses<br />
echolocation to hunt insects, small mammals, birds, reptiles and even<br />
other bats. By making high-pitched sounds and using the length of time<br />
the sound takes to echo back, the bat determines how far away its prey<br />
is and in which direction it is moving.<br />

Silvery Gibbon<br />
Hylobates moloch<br />
Red List Status: Endangered<br />
One of 16 species of gibbon found<br />
across South-east Asia, Silvery<br />
Gibbons are only found on the<br />
tropical Indonesian island of Java.<br />
Gibbons are arboreal, or treedwelling,<br />
and use their long arms to<br />
swing through the tree canopies<br />
faster than most other animals, with<br />
an arm stride of up to three metres.<br />
They are capable of swinging a<br />
distance of up to 15 metres.<br />
Silvery Gibbons are social and live<br />
as an adult pair with up to three<br />
offspring. They are active during the<br />
day, when they forage for wild fruits,<br />
young leaves, flowers and<br />
occasionally small birds and lizards.<br />
Their day starts at dawn with a loud<br />
call that carries several kilometres<br />
and signals their territory to other<br />
gibbons. Females also call when they<br />
are alarmed and the males survey the<br />
area for threats and intruders.<br />
The Silvery Gibbon’s pregnancy lasts<br />
about seven months. The infant is<br />
very dependent on its mother and<br />
clings tightly to its mother’s hair,<br />
rarely leaving her during its first year.<br />
Silvery Gibbons are facing possible<br />
extinction in the wild because humans<br />
have encroached upon their habitat.<br />
A staggering 98% of their habitat has<br />
been lost by human colonisation and<br />
remaining gibbon populations are<br />
highly fragmented, totalling<br />
some where between 400 and<br />
4000 individuals.<br />
Although illegal, young gibbons are<br />
poached from the wild and taken as<br />
pets. Often the mother is killed to<br />
capture the infant.<br />
The remaining Silvery Gibbons in<br />
Java now live in forest habitats<br />
toward the top of mountain ranges<br />
because humans occupy the valleys.<br />
The populations are fragmented and<br />
there is little movement between<br />
populations, resulting in a smaller<br />
genetic pool.<br />
newspaw s | <strong>Summer</strong> <strong>2009</strong>/10<br />
How Can You Help?<br />
If you travel to South-east Asian<br />
countries, avoid having your<br />
picture taken with pet gibbons.<br />
This only strengthens the market<br />
for the illegal pet trade.<br />
Avoid buying furniture made<br />
from Indonesian timber that<br />
is unsustainably harvested.<br />
Donate to <strong>Perth</strong> <strong>Zoo</strong>’s Wildlife<br />
Conservation Action, which<br />
supports the conservation of<br />
Silvery Gibbons in the wild.<br />
<strong>Perth</strong> <strong>Zoo</strong> has a family of four Silvery<br />
Gibbons. Adult female Hecla and<br />
male Jury have produced six offspring,<br />
some of which have moved to other<br />
zoos around the world to form<br />
breeding pairs. The most recent birth<br />
at <strong>Perth</strong> <strong>Zoo</strong> was a female named<br />
Cahaya, who was born in May 2008.<br />
She joins brother Nakula in their<br />
Asian Rainforest exhibit.<br />

Taking a Step for<br />
Sustainability: REmida<br />
Following on from the ‘reduce,<br />
reuse, recycle’ theme of this<br />
segment in the last issue of News<br />
Paws, <strong>Perth</strong> <strong>Zoo</strong> would like to<br />
introduce you to REmida, <strong>Perth</strong>’s<br />
Creative Reuse Centre.<br />
REmida is a non-profit organisation<br />
that first began in Reggio Emilia, Italy,<br />
in 1996. Citizens wanted to provide<br />
opportunities for people to utilise<br />
refuse for creative projects. They<br />
invited local manufacturers to donate<br />
their unused bi-products to REmida,<br />
saving them from landfill and<br />
regenerating them into a creative<br />
resource.<br />
“The name was developed from the<br />
mythological figure of King Midas,<br />
who turned everything he touched<br />
into gold,” says Stephanie Backhouse,<br />
REmida Administrator and Public<br />
Relations Officer. “REmida fosters a<br />
golden perspective on discarded<br />
materials.”<br />
Entering REmida’s offices in East<br />
<strong>Perth</strong>, your eyes are drawn to the<br />
many artistic creations that adorn<br />
the walls, tables and other surfaces.<br />
Taking a closer look, you can see the<br />
carefully created pieces are comprised<br />
of usually understated materials.<br />
REmida challenges the perspective<br />
that industrial off-cuts such as<br />
plastics, wood, metal and ceramics<br />
are unusable or worthless. Instead,<br />
REmida embraces their potential as<br />
vibrant, interesting and dynamic<br />
materials for sculptures, puppets<br />
and other creative uses.<br />
Members pay an annual fee which<br />

allows them to collect unlimited<br />
materials for the duration of their<br />
membership. A range of workshops<br />
and events are offered to students,<br />
teachers and the community.<br />
A workshop on the last Thursday of<br />
every month combats the thrall of<br />
plastic shopping bags by making<br />
bags out of recycled materials. Called<br />
Guerilla Bagging, the bags are then<br />
handed out to the public as a<br />
statement about reducing plastic<br />
bag consumption and for use.<br />
On Saturday afternoons in the Art<br />
Discovery Series, people experiment<br />
and develop new skills by creating<br />
pieces of artwork with recycled<br />
products. These specialised programs<br />
see participants create mechanical<br />
toys, make light catchers and prints.<br />
REmida recently presented a creative workshop for the <strong>Perth</strong> <strong>Zoo</strong><br />
education team and our Docents who assist with education<br />
programs.<br />
After hearing about the REmida philosophy, staff and Docents<br />
familiarised themselves with the nature, properties and potential<br />
uses of the industrial off-cuts. They then created unreal animals<br />
using the materials while exercising their imaginations to develop<br />
a story about their animal – its habitat, behaviours, social<br />
structure and conservation status.<br />
Everyone enjoyed the challenge set by REmida and <strong>Perth</strong> <strong>Zoo</strong><br />
will promote REmida’s philosophy and programs through its own<br />
education experiences.<br />
Schools can visit the REmida Centre<br />
for workshops in puppet-making,<br />
collage, mechanics, art and storytelling<br />
or education officers can visit<br />
them. REmida also offers teacher<br />
professional development on how to<br />
use recycled materials in the<br />
classroom.<br />
School workshops run for two hours<br />
or there are whole-day workshops<br />
for one or two classes available on<br />
Monday, Wednesday and Friday.<br />
School holiday programs are also<br />
available.<br />

engaging ways that you and your<br />
