Chaparral Australia

Climate of the Australian Chaparral

  • Average rainfall is 10-18 inches per year
  • Temperatures fall as low as 30 degrees or as high as 100 degrees on average
  • The Australian Chaparral, also know as Mallee Scrub, has a Mediterranean climate. This means they have long, dry summers with mild, wet winters. It receives sunlight year round with hot days, yet at night, the temperatures drop greatly.

Net Primary Productivity

The Australian Chaparral is not extremely diverse due to it's challenging climate. In order to live in this biome, plants and animals must be adaptable for extreme temperatures can occur and weather can be unpredictable. This lack of diversity is a reason for the Chaparrals low Net Primary Productivity for they don't have many plants to create energy., unlike a tropical rain forest which is rich in plants to create energy. The Chaparral can be found between 30 to 40 degrees North and 30 to 40 degrees South. It makes up 21% of Earth's land surface, which is makes it not the largest, yet not the smallest either.

Soil Quality

The Australian Chaparral's soil has a very low amount of nutrients, which causes it to easily erode. When erosion occurs due to wind or rain, bare rock is usually exposed. This soil quality makes it difficult for farming, for only drought tolerant plants can survive in this type of soil.

Invasive and Endangered

Invasive Cane Toad:

The cane toad was originally from Hawaii, yet was purposefully introduced to Australia in an attempt to control the native grey-backed cane beetle.

Invasive European Rabbit:

The European rabbit was introduced to Australia when Europeans first settled in Australia as a source of meat. They've now become a serious pest and have caused great damage to crops.

Endangered Malleefowl:

The Malleefowl is endangered because they are vulnerable to foxes due to being ground dwellers (I in HIPPCO), climate change is causing more droughts to occur and they do not breed during extreme droughts (C in HIPPCO), and loss of habitat due to land clearings (H in HIPPCO).

Endangered Mallee Emu-Wren:

The amount of Emu-Wren in the Mallee region have greatly shrunk over the past few years due to fires destroying their limited habitat (H in HIPPCO).

Animals in Australian Chaparral

The puma will kill and eat any small to medium sized animal. In the Chaparral this is useful for they can adapt and eat plenty of insects, birds, or mice.

When winter comes around and temperatures drop, the Jackal grows a thick coat of hair to stay warm. However, when temperatures are extremely high, the Jackal stays cool with a thin coat.

The Jackrabbits huge ears regulate its body heat by increasing and decreasing the blood flow through its ears. This allows it to survive the extreme heat and cold nights.

Plants in the Australian Chaparral

The common sagebrush survives in the Chaparral's dry environments by using it's deep roots to find water and absorbs water with shallow roots when it does rain.

The Torrey Pine has wood that does not burn very easily, which allows it to survive any heat fires that may occur from the scorching weather.

The Fairy Duster flower is made up of four pairs of 1/4 inch leaves, which allows it to survive the warm summers with very little water for they store it in their thick leaves.
