Conservation in Australia is an issue of state and federal policy. Australia is one of the most biologically diverse countries in the world, [1] with a large portion of species endemic to Australia. Preserving this wealth of biodiversity is important for future generations. 25% of Australia is managed for conservation. [2]
Animal habitats like reefs and forests must be preserved in order to preserve the population and diversity of animal species. Conservation is vital for future study and for field research to be taken, and because biological richness is an unmeasurable aesthetic that may be developed into commercial recreational attractions.
According to Janine Benyus, the potential for advances in biomimicry in Australia is great because the extreme weather and conditions found here provide an excellent evolutionary incubator. Research on natural processes can only occur if the habitat is preserved and organisms continue to thrive.
Federal and State governments manage protected areas and national parks; a number of non-governmental organizations are also involved in conservation.
A key conservation issue is the preservation of biodiversity, especially by protecting the remaining rainforests. The destruction of habitat by human activities, including land clearing, remains the major cause of biodiversity loss in Australia. The importance of the Australian rainforests to the conservation movement is very high. [3] Australia is the only western country to have large areas of rainforest intact. [4] Forests provide timber, drugs, and food and should be managed to maximize the possible uses. Currently, there are a number of environmental movements and campaigners advocating for action on saving the environment, one such campaign is the Big Switch. [5]
Land management issues including clearance of native vegetation, reafforestation of once-cleared areas, control of exotic weeds and pests, expansion of dryland salinity, and changed fire regimes. Intensification of resource use in sectors such as forestry, fisheries, and agriculture are widely reported to contribute to biodiversity loss in Australia. Habitat fragmentation is one of the most important factors affecting the persistence of species. [2] Coastal and marine environments also have reduced biodiversity from reduced water quality caused by pollution and sediments arising from human settlements and agriculture. In central New South Wales where there are large plains of grassland, problems have arisen from—unusual to say—lack of land clearing.
Shark culling (the killing of sharks) currently occurs in New South Wales and Queensland (in government "shark control" programs). [6] These programs have damaged the marine ecosystem. [6] Roughly 50,000 sharks have been killed by Queensland authorities since 1962, including in the Great Barrier Reef. [7] [8] Queensland's "shark control" program has been called "outdated, cruel and ineffective". [8] The "shark control" programs in New South Wales and Queensland have killed thousands of animals, such as turtles and dolphins. [6] [9] In 2018, the Humane Society International filed a lawsuit against the government of Queensland to stop shark culling in the Great Barrier Reef. [8]
The protection of the iconic Wollemi Pine is an important conservation issue because the tree is one of the rarest in the world. [10] There are only 46 mature individual trees remaining in the wild. [10] The small grove of unusual conifers in a remote canyon are threatened due to its highly restricted distribution, extremely small population size, the ongoing impacts from exotic pathogens, inappropriate fire regimes, unauthorized site visitation and climate change. [10]
Specific issues:
Conservation of the natural environment in Australia is derived from five different sources of law, namely international law, federal law, State law and local government law as well as the application of the common law.

There are numerous protected areas in all States and Territories that have been created to protect and preserve Australia's unique ecosystems. Protected areas include national parks and other reserves, as well as 64 wetlands which are registered under the Ramsar Convention and 16 World Heritage Sites. As of 2002 [update] , 10.8% (774,619.51 km2 or 299,082.26 sq mi) of the total land area of Australia is within a protected area. [11] Protected marine zones have been created in many areas to preserve marine biodiversity; as of 2002 they cover about 7% (646,000 km2 or 249,000 sq mi) of Australia's marine jurisdiction. [12] In Australia forest cover is around 17% of the total land area, equivalent to 134,005,100 hectares (ha) of forest in 2020, up from 133,882,200 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 131,614,800 hectares (ha) and planted forest covered 2,390,300 hectares (ha). Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 18% of the forest area was found within protected areas. For the year 2015, 67% of the forest area was reported to be under public ownership, 32% private ownership and 1% with ownership listed as other or unknown. [13] [14]
Protected areas of include those managed by the federal Department of the Environment and Energy, and national parks and other protected areas managed by the states, Agencies responsible for protected areas include:
A number of governmental and non-governmental organisations work in the conservation and restoration of the Australian environment.
Protected areas of Australia include Commonwealth and off-shore protected areas managed by the Australian government, as well as protected areas within each of the six states of Australia and two self-governing territories, the Australian Capital Territory and the Northern Territory, which are managed by the eight state and territory governments.
The Great Barrier Reef is the world's largest coral reef system, composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 160 kilometres (100 mi) wide in places and over 61 metres (200 ft) deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the Seven Natural Wonders of the World in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006.
Protected areas of South Australia, consisting of protected areas located within South Australia and its immediate onshore waters and which are managed by South Australian Government agencies. As of 2018, South Australia contained 359 separate protected areas declared under the National Parks and Wildlife Act 1972, the Crown Land Management Act 2009 and the Wilderness Protection Act 1992. Together, they cover a total land area of 211,387.48 km2 (81,617.16 sq mi) or 21.5% of the state's area.
The Border Ranges National Park is a protected national park that is located in the Northern Rivers region of New South Wales, Australia. A small portion of the national park is also located in South East Queensland. The 31,729-hectare (78,400-acre) park is situated approximately 150 kilometres (93 mi) south of Brisbane, north of Kyogle.
The Springbrook National Park is a protected national park that is located in the Gold Coast hinterland of Queensland, Australia. The 6,197-hectare (15,310-acre) park is situated on the McPherson Range, near Springbrook, approximately 100 kilometres (62 mi) south of Brisbane. The park is part of the Shield Volcano Group of the UNESCO World Heritage–listed Gondwana Rainforests of Australia.
The Gondwana Rainforests of Australia, formerly known as the Central Eastern Rainforest Reserves, are the most extensive area of subtropical rainforest in the world. Collectively, the rainforests are a World Heritage Site with fifty separate reserves totalling 366,500 hectares from Newcastle to Brisbane.
The Queensland Parks and Wildlife Service (QPWS) is a business division of the Department of Environment and Science within the Government of Queensland. The division’s primary concern is with the management and maintenance of protected areas within Queensland, to protect and manage Queensland’s parks, forests and the Great Barrier Reef for current and future generations.
The Australian Marine Conservation Society (AMCS) is an Australian environmental not-for-profit organisation. It was founded in 1965 as the Queensland Littoral Society before changing its name to the Australian Littoral Society and then finally in 1995 to its current title. It works on protecting the health and vitality of Australia's coasts and oceans.
The Wildlife Preservation Society of Queensland based in Queensland, Australia is a not-for-profit organisation which aims to engage communities to deliver conservation outcomes.
The Australian environment ranges from virtually pristine Antarctic territory and rainforests to degraded industrial areas of major cities. Forty distinct ecoregions have been identified across the Australian mainland and islands. Central Australia has a very dry climate. The interior has a number of deserts while most of the coastal areas are populated. Northern Australia experiences tropical cyclones while much of the country is prone to periodic drought. This dry and warm environment and exposure to cyclones, makes Australia particularly vulnerable to climate change -- with some areas already experiencing increases in wildfires and fragile ecosystems.
Since declaring independence in 1981, Belize has enacted many environmental protection laws aimed at the preservation of the country's natural and cultural heritage, as well as its wealth of natural resources. These acts have established a number of different types of protected areas, with each category having its own set of regulations dictating public access, resource extraction, land use and ownership.
Land clearing in Australia describes the removal of native vegetation and deforestation in Australia. Land clearing involves the removal of native vegetation and habitats, including the bulldozing of native bushlands, forests, savannah, woodlands and native grasslands and the draining of natural wetlands for replacement with agriculture, urban and other land uses.
The Moreton Bay Marine Park was established in 1993 to protect ecologically significant habitats in Moreton Bay. The marine park extends from Caloundra south to the southern tip of South Stradbroke Island. The marine park's border extends up to the highest tidal mark and covers a total of 3,400 km2.
Earthwatch Institute is an international environmental charity. It was founded in 1971 as Educational Expeditions International by Bob Citron and Clarence Truesdale. Earthwatch Institute supports Ph.D. researchers internationally and conducts over 100,000 hours of research annually using the Citizen Science methodology. Earthwatch's mission statement states that the organization "connects people with scientists worldwide to conduct environmental research and empowers them with the knowledge they need to conserve the planet." As such, it is one of the global underwriters of scientific field research in climate change, archaeology, paleontology, marine life, biodiversity, ecosystems and wildlife. For over fifty years, Earthwatch has raised funds to recruit individuals, students, teachers, and corporate fellows to participate in field research to understand nature's response to accelerating global change.
A drum line is an unmanned aquatic trap used to lure and capture large sharks using baited hooks. They are typically deployed near popular swimming beaches with the intention of reducing the number of sharks in the vicinity and therefore the probability of shark attack. Drum lines are often used in association with shark nets, which results in shark mortality. However SMART drum lines can be used to move sharks, which greatly reduces shark and bycatch mortality. The use of drum lines has been successful in reducing shark attacks in the areas where they are installed. The topic of shark culling became an international controversy and sparked public demonstrations and vocal opposition, particularly from environmentalists, animal welfare advocates and ocean activists.
Shark culling is the deliberate killing of sharks by government authorities, usually in response to one or more shark attacks. The term "shark control" is often used by governments when referring to culls. Shark culling has been criticized by environmentalists, conservationists and animal welfare advocates—they say killing sharks harms the marine ecosystem and is unethical. Government officials often cite public safety as a reason for culling. The impact of culling is also minor compared to bycatch with 50 million sharks caught each year by the commercial fishing industry.
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Western Australian government department responsible for managing lands and waters described in the Conservation and Land Management Act 1984, the Rottnest Island Authority Act 1987, the Swan and Canning Rivers Management Act 2006, the Botanic Gardens and Parks Authority Act 1998, and the Zoological Parks Authority Act 2001, and implementing the state's conservation and environment legislation and regulations. The Department reports to the Minister for Environment and the Minister for Tourism.
The Windsor Tablelands are a series of plateaus located in Far North Queensland, Australia. The Windsor Tableland and surrounding rainforest area are contained as part of the Wet Tropics of Queensland, sitting between the Daintree Rainforest and Mount Lewis National Park. Additionally, the region is contained in the state electorate of Cook and situated in the greater Tablelands Region of North Queensland. The Tablelands hug the mountain ranges of the Great Dividing Range with the nearest town being Wujal Wujal. The Tableland area is a larger part of the Mount Windsor Forest Reserve which represents 44,000 hectares of land in the Wet Tropic region and is a conserved nature area, as proclaimed by the Government of Queensland in 2005. Predominately the majority of the Mount Windsor Tableland is closed off for any form of public use and access to the area is often only given on request. There is currently no residential population in the Mount Windsor Tableland region as a majority of the area is national park.
