The population density in Australia beyond the coastline and major cities has been very low since the arrival of European settlers, and there are large tracts of land where it is very difficult for people to manage even large feral animals like camels, horses, donkeys and water buffalos.
This is a list of all major natural disasters in Australian European history. The natural disasters included here are all the notable events that resulted in significant loss of life or property due to natural, non-biological processes of the Earth within Australian territory. Due to inflation, the monetary damage estimates are not comparable.
However, if food supplies are good and there’s plenty of cover for hiding, you can have 10 or more chipmunks per acre! Only the eastern chipmunk ( Tamias striatus ) lives in the Southeast.
Chipmunks and squirrels are lovable creatures and fun to watch – but they can ruin your carefully tended landscape by digging holes in your yard and scattering mulch.
According to Tim Flannery (The Future Eaters), fire is one of the most important forces at work in the Australian environment.Some plants have evolved a variety of mechanisms to survive or even require bushfires (possessing epicormic shoots or lignotubers that sprout after a fire, or developing fire-resistant or fire-triggered seeds), or even encourage fire (eucalypts contain flammable oils in ...
Soil salinity affects 50,000 km 2 of Australia and is predominantly due to land clearance. The clearing of native vegetation is controlled by Federal laws (indirectly), State law and local planning instruments. The precise details of regulation of vegetation clearing differ according to the location where clearing is proposed.
Protected areas cover 895,288 km 2 of Australia's land area, or about 11.5% of the total land area. Of these, two-thirds are considered strictly protected (IUCN categories I to IV), and the rest is mostly managed resources protected area (IUCN category VI). There are also 200 marine protected areas, which cover a further 64.8 million hectares. [3]
The largest known area burnt was between 100–117 million hectares (250–290 million acres), impacting approximately 15 per cent of Australia's physical land mass, during the 1974–75 Australian bushfire season. [4] The highest number of homes destroyed was approximately 3,700 dwellings, attributed to Victoria's 1939 Black Friday bushfires. [5]
