Low became interested in reptiles as a teenager, and discovered several new species of lizard. The chain-backed dtella (Gehyra catenata) and the dwarf litter-skink (Menetia timlowi) were named after him. It was later renamed Pygmaeascincus timlowi . [1]
His report, Climate Change and Queensland Biodiversity, was announced in Queensland parliament by environment minister Kate Jones in June 2011. In that year, Low traveled to Europe and Alaska to study climate change under the Churchill Fellowship. Low also ran a workshop in Canberra, writing up a report titled Climate Change and Invasive Species. He has written journal articles that caution about the weed threats posed by biofuel crops, agroforestry trees, and pasture plants.
For two years (2013–2015), Low was co-editor of Wildlife Australia magazine. For twenty years, he wrote a column in Nature Australia. For two years, he wrote the Wild Journey blog for Australian Geographic magazine. He co-authored a 2023 report that reviewed the causes of Australia's modern extinctions. [2]
Low lives in Brisbane. He was appointed a Member of the Order of Australia in the 2024 King's Birthday Honours for "significant service to conservation, and environmental education and awareness". [3]
His seventh book, Where Song Began: Australia's Birds and How They Changed the World, tells the story of Australia as a land of aggressive birds that gave the world its songbirds and parrots. Published in Australia by Penguin and internationally by Yale University Press, it won the Australian Book Industry Awards prize for best General Non-Fiction in 2015 and People's Choice at the Victorian Premier's Literary Awards. It was also shortlisted for the NSW Premier's History Awards. [4]
The New Nature: Winners and Losers in Wild Australia (2002) explains that some native species benefit from human impacts, sometimes going on to cause environmental problems. It won the inaugural Westfield-Waverley literary award, now called The Nib and received a special mention at the Centre for Australian Cultural Studies National Awards. Because of this book, Low was invited to serve on the advisory committee (Biological Diversity Advisory Committee) of then-environment minister, Senator Ian Campbell.
Feral Future: The Untold Story of Australia's Exotic Invaders (1999) surveyed the problems caused by invasive species. It was republished by the University of Chicago Press. An extract was read out in the Australian Senate. Low appeared in a TV New Zealand episode of Assignment named after the book. Feral Future inspired the formation of an NGO, the Invasive Species Council. [5] Low had spoken about its formation at the 18th Global Biodiversity Forum in Mexico in 2001.
Biodiversity is the variety and variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa.
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide.
Brisbane Water National Park is a national park on the Central Coast of New South Wales, Australia. The national park is situated 70 kilometres (43 mi) north of Sydney and 12 kilometres (7.5 mi) southwest of Gosford. It consists the Brisbane Water and Mooney Mooney Creek waterways.
Goobang is a national park located in New South Wales, Australia, 296 kilometres (184 mi) northwest of Sydney. It protects the largest remnant forest and woodland in the central west region of the state, where interior and coastal New South Wales flora and fauna species overlap. Originally named Herveys Range by John Oxley in 1817, the area was reserved in 1897 as state forest because of its importance as a timber resource, and was designated a national park in 1995.
Eungella National Park is a protected area in Queensland, Australia. It is on the Clarke Range at the end of the Pioneer Valley 80 km west of Mackay, and 858 km northwest of Brisbane. Eungella is noted for the national park which surrounds it. It is considered to be the longest continual stretch of sub-tropical rainforest in Australia. The original inhabitants are the Wirri people. The park is covered by dense rainforest and is known for its platypuses.
Taunton National Park is situated near the town of Dingo approximately 135 km inland from Rockhampton in eastern Central Queensland, Australia. The park encompasses an area of 11,626 ha within the Northern Brigalow Belt bioregion of Queensland; a region widely recognised to contain considerable biodiversity.
A feral animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration.
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are new biota to their environment in terms of established biological network relationships. Neobiota can further be divided into neozoa and neophyta (plants).
Invasive species in Australia are a serious threat to the native biodiversity, and an ongoing cost to Australian agriculture. Numerous species arrived with European maritime exploration and colonisation of Australia and steadily since then. There is much ongoing debate about the potential benefits and detriments of introduced species; some experts believe that certain species, particularly megafauna such as deer, equids, bovids, and camels, may be more beneficial to Australia's ecosystems than they are detrimental, acting as replacements for extinct Australian megafauna.
Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution, climate change, and the illegal wildlife trade. The IUCN estimates that 42,100 species of the ones assessed are at risk for extinction. Expanding to all existing species, a 2019 UN report on biodiversity put this estimate even higher at a million species. It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife. Prominent conservation agreements include the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the 1992 Convention on Biological Diversity (CBD). There are also numerous nongovernmental organizations (NGO's) dedicated to conservation such as the Nature Conservancy, World Wildlife Fund, and Conservation International.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups, such as New Zealand and Hawaii, have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species.
A brumby is a free-roaming feral horse in Australia. Although found in many areas around the country, the best-known brumbies are found in the Australian Alps region. Today, most of them are found in the Northern Territory, with the second largest population in Queensland. A group of brumbies is known as a "mob" or "band".
Western Shield, managed by Western Australia's Department of Parks and Wildlife, is a nature conservation program safeguarding Western Australia's animals and protecting them from extinction. The program was set up in 1996 and as of 2009 was the largest and most successful wildlife conservation program ever undertaken in Australia.
The Paroo-Darling National Park is a protected national park that is located in the Far West region of New South Wales, in eastern Australia. The 178,053-hectare (439,980-acre) national park spans two distinct regions in the outback area. This region covers the arid catchments of the Paroo River and the Paroo-Darling confluence to the south.
Feral cats are an invasive species in Australia. Because they are not native to Australia and were only introduced by European colonists as pets in the early 1800s, native Australian animals did not co-evolve with them. As of 2016, some 3.8 million domestic cats and up to 6.3 million feral cats continue to live in Australia.
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction and land use intensification. Further problem areas are air and water pollution, over-exploitation, invasive species and climate change.
The Invasive Species Council is an Australian environmental non-governmental organisation founded in 2002 to provide a specialist policy and advocacy focus on reducing the threat of invasive species that threaten the environment.
An escaped plant is a cultivated plant that has escaped from agriculture, forestry or garden cultivation and has become naturalized in the wild. Usually not native to an area, escaped plants may become invasive. Therefore, escaped plants are the subject of research in invasion biology.
