Out
in the Bush

Ever
seen those people driving around in National Parks and
Reserves? Wonder what they are doing? This morning, I
am out with Tanya Leary from the National Parks and Wildlife
Services of NSW and Nick, a fellow volunteer. Tanya is
involved with conducting plant and animal surveys to provide
information about what we have in our parks, and also
to provide advice for the management of our reserves in
Sydney.

We
are up nice and early for trip out to Mulgoa, at the foot
of the Blue Mountains. We arrive there near on 6am, after
a 4:30am wake up call. Tanya greets us enthusiastically
for someone who has had to get up this early for the past
month. We hop into the big ute, and off we go. First we
stop to check a couple of the small mammal traps left
out over night. "I see it!” calls Nick.

Who
are you looking at? |
We
trudge towards the base of the tree, where the cage sits.
It ispitch black. "Nup, nothing" calls Tanya,
whilst we investigate a nearby tree. Nick spots something
– a bearded dragon about 25cm long. We all crowd around
the tree, eyeing this reptile whose claws are dug firmly
into the bark. Tanya gently picks it up. We gather around.
So here are a few lunatics, at 6am, peering at this puzzled
creature in the middle of nowhere. The lizard is very
cold. Lizards, like snakes and other reptiles, cannot
make their own body heat. They are ectotherms. They must
sit in the sun, or on hot rocks, to get their body temperature
up. At the moment, it is too cold to move.

After
a while of photographing, the lizard squirms. It is scaly
and dry – much like sandpaper. “He’s getting warmed up
in my hands… and annoyed,” comments Tanya. “I better let
him go.”
The
sun is rising quickly. The next thing we have to do is
check the Eliot traps. These small rectangular metal traps
are used to catch small mammals as well as lizards. We
have to get any animals out of the trap
quickly before they cook in the sun.

blue tongue lizard. My tongue is longer than yours! |
"Something
I should warn you two," says Tanya. "One of
you might have to get on your hands and knees to reach
the traps." Nick and I point at each other. After
a short talk, I volunteer.
We
jump out of the ute and head toward the dense bush. Tanya
gives me a briefing, handing me several hessian bags and
some bait. “The traps are every ten metres, where the
pink tape is. There’ll be twenty straight ahead, then
turn right and head for another 100 metres. I’ll meet
you in the clearing. Good luck!”
So
here I am, facing the unusual green of the Australian
bush. It is chilly, the sun is just behind me, and the
ground is wet from last night’s rain. Every ten metres,
I stop and check a trap. It does not take long to get
something – ah, only a mouse. Mice have a tendency to
pee... It's not a nice smell to say the least! Well, I
drop him into the sack and move to the next one. The bush
here is very thick, and I creep slowly down a steep wet
hill that is covered in plants and shrubs. I catch a few
more mice. After a while all I smell is mouse pee and
peanut butter from the bait!
Somehow,
I lose the trail of the flagging tape I should be following.
I trudge up a small slope. I hear a rustling, and then
a loud THUMP. “Nick?” No reply. THUMP... THUMP... I can
see no one... And then I realise what is making those
noises – A swamp wallaby. Eventually, I finish checking
all the traps and turn to head back. Which way is it?
I have taken longer than normal, and Tanya and Nick are
getting anxious. And so am I. “ALAN?” I hear Nick call.
Sounds like he is miles away. He calls again. I swear
it came from the opposite direction this time!
“YEAH?”
I yell. They don't hear me. I start jogging while I remember
which way the call came from. After a few minutes, I find
them. Safe! We have a break for a cup of coffee and some
fruit cake. Ah, it is nice to rest your feet.
On
the way to the next spot, we check another small mammal
trap. We find a large blue-tongue lizard. Tanya lifts
it up carefully. Its beautiful body is smooth underneath
and quite smooth on top. It does not seem to mind, probably
because it has found a nice warm object to sit on. But
do not try this at home. Most blue tongues will bite when
annoyed, and they do not let go very easily. They can
hold on for over half an hour, much to your discomfort.
If that is not enough, their tails can fall off. Tanya
places the blue-tongue back into the bushes, and we head
off.
It
is getting toward noon, and we had better do the Reptile
search. What we are doing here is counting all the different
types of reptiles we see – snakes (didn’t see one!), lizards,
skinks. There is nothing much out today. It is too cold,
and clouds cover the sun. Our search loses enthusiasm.
We walk through the bush, admiring the beauty of nature.
We pass the small nests of green ants who defend their
nest with their huge orange mouthparts. We spot the old
nest of a male Bowerbird. The males build an elaborate
nest on the ground, and litter it with items of a particular
colour to attract a female. This bird seemed to like blue
objects - the ground was littered with blue berries, feathers,
and plastic.
At
1 o’clock, this field trip comes to an end, and we all
head back to civilisation. It is great to get out to the
bush, away from the bustling world of people. Australia's
natural world is unique, amazing, and inspiring. I hope
in years to come, I can still do what I have done on this
day without hearing the roar of cars and smelling the
fumes of the city. If I can't, then we have lost a special
part of Australia that we can never get back.
