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 />

using the PiCus ® . machine.<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 />

genetic diversity are maintained and a sustainable<br />

breeding population is formed.<br />

<strong>Perth</strong> <strong>Zoo</strong>’s Quokkas can be seen in the Australian<br />

Bushwalk.<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 />

Wetlands sees one of <strong>Perth</strong> <strong>Zoo</strong>’s biggest stars<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 />

family can reduce, reuse and recycle<br />

materials, contact REmida on<br />
