The Effects of Climate Change on Australian Tropical

Rainforests

About Australia’s Tropical Rainforests

The tropical rainforests of Australia are beautiful tourist attractions, boasting

many rare plants and animals found in no other Australian ecosystems. Australian

tropical rainforests receive at least 1.3m of rain per year, an incredible amount. This is

why they are so lush and green and are able to support many species of animals that temperate rainforests can’t. The Daintree rainforest is Australia’s main

tropical rainforest.

Flora Found in Australian Tropical Rainforests

Australian tropical rainforests are home to many amazing and unique plants; in fact, the Daintree rainforest contains 12 of the

19 primitive plant families found on Earth. In Australia’s tropical rainforests, you can

find:• 65% of Australia’s ferns

• 21% of Australia’s cycads• 37% of Australia’s conifers

• 30% of Australia’s orchid species.

Fauna found in Australian Tropical Rainforests

The range of animals found in Australia’s tropical rainforests is incredibly huge. In

these rainforests, you can find: • 36% of Australia’s mammals• 30% of Australia’s marsupials• 60% of Australia’s butterflies

• 48% of Australia’s bird species• 25% of Australia’s frogs and reptiles

• 37% of Australia’s freshwater fish• 50% of Australia’s bat species

Australian tropical rainforests are home to many species of endangered frogs.

Impact of Climate Change

Climate change has impacted greatly on many ecosystems around the

world, including Australian tropical rainforests. If nothing is done to

combat climate change, the numbers of plants and animals found in these rainforests will fall even faster than

they already are.

There are many animals that rely greatly on plants for survival. These animals use the plants for food and

habitat purposes. Unless something is done about climate change, these

already endangered plants will soon become extinct, leaving these animals

stranded. In Australian tropical rainforests there are lots of

endangered animals including many species of frogs. If the world’s

temperature continues to rise at the same rate it is, we will lose many

precious species of animals.

Rising sea levels are also a problem. Because of climate change, sea levels will rise at a frightening rate, causing coastal erosion and threatening parts

of Australia’s tropical rainforests. If temperatures rise by 0.8°C, we could

lose at least 50% of many, many special and unique species. We need to do something about climate change so that the next generation will get a

chance to see these precious species.

What Needs to be Done?

Ultimately, to reduce the impact of climate change on Australian tropical rainforests, we need to severely cut down our greenhouse gas emissions.

Now, this may seem impossible for one average person, but we can all do little things to help reduce global

greenhouse gas emissions.

Some little things that the average person can do to help reduce greenhouse gas

emissions include:• Turning off lights when you leave a room• Turning off appliances when not in use

• Fixing all dripping taps• Turning off appliances at the wall

• Switching to natural energy sources• Using public transport/walking/riding a

bike
