the

The Australian Outback: A Documentary

Australia a country full of aquatic and

terrestrial life it is home to a variety

of plants and animals that have adapted

to the different conditions over 80% of

the animals are unique to Australia and

cannot be found anywhere else in the

world Australia's most iconic biome is

the desert ecosystem known for its

kangaroos and dingoes the desert biome

is a system of plants and animals that

have adapted to the harsh conditions of

the outback

the Australian outback in the Northern

Territory has two different climates the

Darwin climate is tropical with high

humidity and a wet season from October

to April and a dry season from May to

September the central region climate is

a desert requirement with very little

rainfall and the hottest months from

October to March soil erosion is a large

problem in the Northern Territory of

Australia due to topsoil being washed

away by water this causes a loss of

vegetation and increase in the turbidity

of waterways and a decrease in soil

fertility the soil is rocky low in

nutrients and slightly acidic so it

doesn't have the capabilities of

agricultural development

some of the animals that live in the

Northern Territory are Dingles

freshwater and saltwater crocodiles

kangaroos wombats billa bees insects and

various types of snakes and lizards the

producers in the Northern Territory are

small shrubs and short desert grasses

water is not always available in the

outback

so herbivores have adapted to the

situation by being able to survive long

periods of time without water red

kangaroos eat early in the morning when

there's dew on the plants as a source of

water wombats get the water they need by

storing their food in burrows where the

air is humid the food absorbs the humid

air so that when the wombats eat their

food they get water as well a keystone

species in the outback is a dingo

dingoes are wild dogs that either live

alone or hunt in packs they hunt small

game such as wombats kangaroos birds and

lizards and they also eat fruits and

plants because they eat so many

different kinds of animals they have

many different roles in the food chains

Dingles have also evolved to survive in

this region the fur of the dingoes coat

is largely determined by where it lives

a standard coat color is ginger with

white feet but in the desert areas their

fur is golden yellow desert dingoes are

also smaller and more compact and their

coats are double layered with a thick

undercoat to insulate them from both

extreme heat and cold weather their

bottle shaped tails help them to balance

and their large heads and narrow chest

and shoulders and proportionate body

make them successful hunters

human contributions to global warning

have greatly changed the habitats for

animals in kakadu park over the past 50

years saltwater intrusion has caused the

tidal range of creeks to move 400

kilometers inland to the East Alligator

River catchment which resulted in an

increase of saline mud flats that killed

two thirds of the Molalla kueh forests

this forest was an important resting

spot for many water birds and used to be

used for spawning by aquatic animals

another environmental problem caused by

humans is the introduction of the cane

toad in June 1935 the toad was brought

from Hawaii by the Bureau of sugar

experiment stations because it was

intended to control the native cane

beetle which was harmful to the

sugarcane plantations in Australia this

told population rapidly increased and

spread from Queensland to New South

Wales and to the Northern Territory the

population is now estimated to be over

200 million and these toads migrated

about 25 miles per year these poisonous

toads have decreased the biodiversity in

Northern Territory ecosystems in local

areas the population of the Verena span

hopes decreased by 90% once it was

invaded by the cane toads there has also

been a decline in the populations of the

northern Quall clearing land for

agricultural purposes is also a cause

for the decreased biodiversity in the

Northern Territory 17 million hectares

of land have been cleared since 1973

urban development also serves as an

aspect of the country that will further

increase the clearing of natural

environments

the northern koala is an endangered

northern native cat

it is a carnivorous marsupial that is

now only found in the Northern Territory

and Cape York Australia the cane toad

population is blamed for the reduction

of this animals population because they

compete for the koalas food and shelter

the calls also die from the toads fatal

poison when they try to eat them

scientists at the University of Sydney

are trying to teach calls not to eat the

toads by putting a chemical into the

toads that make the calls feel nauseated

thus discouraging them from eating the

toad the Tasmanian Devil is another

endangered carnivorous marsupial it has

the most powerful bite of any animal in

the world measured by the power of the

bite per unit of body mass in 1941 there

was a law to protect these animals from

hunters but the Tasmanian Devil

population is threatened by the devil

facial tumour disease this disease is a

genetic trait that causes tumors to grow

around the animals mouth and hipot the

animals ability to eat the starving the

animal to death devil facial tumour

disease has affected between 50 to 90%

of the Tasmanian Devil population

here are some animals in the Australian

outback food web dingoes are carnivorous

scavengers they eat red kangaroos

wombats bilbies and lizards wedge-tailed

Eagles eat small kangaroos wombats

abilities and lizards frill-necked

lizard and Phil V's eat bulldog ants

bulldog ants eat wood white butterflies

desert plants are producers and are

eaten by kangaroos wombats bilbies

butterflies and Bulldog ant the

Australian outback is a biome that is

home to a diversity of plants and

animals many of the plants and animals

are unique to Australia and it is

important that we protect them from

becoming extinct
