According to IUCN Red List, there are approximately 2,000 mature Leadbeater’s possums today, 200 of which are found at Yellingbo. [2] They have an average body length of 33 cm (13 inches) with the tail included. Photo Ark is a multiyear effort to document every species living in wildlife sanctuaries and zoos. Once thought to be extinct, the Leadbeater's Possum was rediscovered in 1961. Due to the constant attacks, young females are forced to leave much earlier than their male brothers, which results in the extremely high male to female ratio of 3:1.[19]. What is a Leadbeater’s Possum? Leadbeater's possum (Gymnobelideus leadbeateri) is a critically endangered possum largely restricted to small pockets of alpine ash, mountain ash, and snow gum forests in the Central Highlands of Victoria,[3] Australia, north-east of Melbourne. [22], The only remaining population outside the Central Highlands is located at Yellingbo Nature Conservation Reserve. [16] From its peak in the 1980s, the Leadbeater's possum population was expected to further decline rapidly, by as much as 90%,[2] due to a habitat bottleneck. [40], Since 2004, the Friends of Leadbeater's Possum community group has been active in raising the animal's profile and lobbying for its conservation. Approximately 45% of their prime habitat and population was lost in these fires. The population has dropped sharply since 1996. P opulations of hollow-bearing trees, the key A wildfire in 1939 created suitable habitat for the Leadbeater’s Possum’s current range and led to a peak in population numbers, estimated to be about 7500 individuals in the early 1980s. Healesville Sanctuary's captive breeding program for Leadbeater's possums recommenced in May 2012 and now comprises 6 individuals from the genetically distinct Yellingbo population. "[35] These changes to the Sustainable Forests (Timber) Act 2004 will have implications not only for the Leadbeater's possum but to the biodiversity, carbon storage and water catchments of the forests. In 2013 it was proposed to create the "Great Forest National Park" to protect the mountain ash forest habitat. The entire Central Highlands population distribution is confined to a 70 by 80 kilometre area. [5] They also go by the common name of fairy possum. The population has dropped sharply since 1996. This particular marsupial resides at the Healesville Sanctuary in Australia. The Leadbeater’s Possum lives in forests close to Melbourne. 2009 Black Saturday bushfires destroy around 45% of reserved LbP habitat and population numbers in the wild are halved. Leadbeater's possums and their forest habitat have been the subject of the largest longitudinal study of any species in the world—conducted by David Lindenmayer, a professor at the Australian National University, and his research assistants since 1983. Particularly, the February 2009 Black Saturday bushfires destroyed 43% of Leadbeater’s possums’ habitat in the Central Highlands. As we are a not-for-profit organisation, all donations go towards our conservation efforts. Leadbeater’s Possums have very specific habitat requirements to survive and flourish. Formerly, Leadbeater's possums were moderately common within the very small areas they inhabited; their requirement for year-round food supplies and tree-holes to take refuge in during the day restricts them to mixed-age wet sclerophyll forest with a dense mid-story of Acacia. It lives in colonies of two to ten possums in the acacia and eucalyptus forests in Australia’s central Victoria. [citation needed], On 14 September 2017, National Geographic reported that the Leadbeater's possum was the 7,000th animal photographed for The Photo Ark by Joel Sartore. More than one million trees and shrubs were planted between 2014-2018. [30][31], In 2012 MyEnvironment challenged VicForests' operations in three planned coupes in the Toolangi forest in the supreme court. [27] Studies have shown that clear-felling operations, such as the logging run in state forest between the Yarra Ranges National Park and Mount Bullfight Conservation Reserve in February 2006, led to the deaths of most possums in the area—"Adult animals have a strong affinity with their home range and are reluctant to move". On 22 April 2015, Greg Hunt, the Minister for the Environment, announced that the Leadbeater's possum would be listed as a "critically endangered" species under the EPBC Act. [41][failed verification] The predation in early 2012 by a feral cat[citation needed] of the few Lake Mountain Leadbeater's possums remaining after the 2009 bushfire led to three remaining individuals being taken into captivity for their own protection. Leadbeater's Possum population crashes by two thirds in past 20 years: report. The basis of their claim being that "VicForests did not undertake adequate pre-logging surveys prior to logging in an area that we claim meets Leadbeater’s habitat and therefore should not have been logged. It is found in Australia. [12], By the time of the 1939 Black Friday fires, the species was thought to have been extinct. These two Lake Mountain animals are now on public display in the Nocturnal House as ambassadors for the species. [18] All members sleep together in a nest made out of shredded bark in a tree hollow, anywhere from 6 to 30 metres above ground level and roughly in the centre of a territory of 3 hectares, which they defend actively. These possums rely on tree hollows, in which small colonies of up to 12 will sleep together. [34], On 27 June 2013 the Napthine led State government passed legislative changes to allow VicForests access to Victoria's forests for the next 25 years and to be self monitoring (this follows the success of other recent cases preventing logging of remaining possum habitat). The case was lost by MyEnvironment due to inconsistencies in the wording of the Leadbeater's Possum Action Statement (10 years out of date) and the forestry prescriptions adhered to by VicForests. Particularly, the February 2009 Black Saturday bushfires destroyed 43% of Leadbeater’s possums’ habitat in the Central Highlands. There are now thought to be only about 1,500 Leadbeater’s possums left in the wild. There is also a small population at Yellingbo, about 50 km east of Melbourne. [4] Clearfell logging and salvage logging (after bushfires) have been proven by the researchers to have been the greatest threat to the possums' conservation in the wild over the last three decades of the 20th century. It weighs 120 grams – about the weight of an iPhone. The forestry industry and Barnaby Joyce advocate for the Leadbeater's possum to be taken off the critically endangered list. Births are usually timed for the beginning of winter (May and June) or late spring (October and November). As of May 2015,[update] they are housed as pairs in large enclosures off display, but are yet to breed. In May 2006, the last Australian specimen at the time, held at Healesville Sanctuary, died. Only about six inches long, not including the tail, and weighing about a quarter of a pound, the Leadbeater’s possum (Gymnobelideus leadbeateri) may be tiny, but it is fast and feisty. ). Now, after the fires, there are estimated to be less than 1,000. Department of Environment, Land, Water and Planning. We are applying emergency recovery measures for the last lowland population that now contains fewer than 40 … Harley has estimated this population to be fewer than 50. [4] It is primitive, relict, and non-gliding, and, as the only species in the petaurid genus Gymnobelideus, represents an ancestral form. Photo Ark: Leadbeater’s Possum Photo Ark: Leadbeater’s Possum Small but feisty, the Leadbeater’s possum (Gymnobelideus leadbeateri) depends on a mix of old and young trees for food and shelter. Post-fire estimates are sitting around 1,500. Federally, Leadbeater’s Possum is listed under the Environment Protection & Biodiversity Conservation (EPBC) Act 1999 as endangered. The then minister for the environment, Tony Burke, agreed with the nomination and forwarded the application to the scientific committee of the EPBC Act requesting urgent consideration. Mating occurs only once a year, with a maximum of two joeys being born to each pair. Their diet is omnivorous: feeding on a range of wattle saps and exudates, lerps, and a high proportion of arthropods which they find under the loose bark of eucalypts, including spiders, crickets, termites and beetles. It is now considered that cats may be a more significant threat to possum populations, particularly in areas already disturbed by logging or bushfires. Numbers last updated November 2018 The Leadbeater’s Possum is a priority for Zoos Victoria. 2009). The species is found only in Victoria, and lives primarily in the ash forests and sub-alpine woodlands of Victoria's central highlands, with a small lowland population to the east of Melbourne.

Mount Baw Baw, Lake Mountain, and Mount Bullfight). Learn about its special habitat and why this tiny mammal is disappearing. The Leadbeater's Possum Advisory Group has now been assembled to foster this struggling species. [citation needed], Des Hackett is credited as the first person to successfully breed the Leadbeater's possum in captivity. Healesville Sanctuary have set up special enclosures with infrared cameras to monitor the possum’s behaviour and are Protecting the Leadbeater’s Possum. As of 2013,[update] Leadbeater's possums are found in three habitat types: lowland swamp gum, of Yellingbo Nature Conservation Reserve; montane ash forest, wet sclerophyll forest dominated by mountain ash, shining gum and alpine ash with a dense mid-story of acacia species; sub-alpine woodlands of Mount Baw Baw, Lake Mountain and Mount Bullfight. Leadbeaters Possums Victoria's Magical Little Emblem - Leadbeaters Possums The Leadbeater's Possum is Victoria's State Faunal emblem. [33] During the case, film was recorded of a Leadbeater's possum in the contested coupe area. The appeal was lost. … The genetic data in this collection were derived from two sources (1) genotypes for a panel of 15-20 highly resolving microsatellite markers, and (2) 30 unique mitochondrial D-loop sequences (haplotypes). It is listed as Critically Endangered in The Action Plan for Australian Mammals (Woinarski et al., 2014, CSIRO). The possum was long thought to be extinct until in 1961 when scientists rediscovered. The IUCN (International Union for the Conservation of Nature) Red List of Threatened Animals 1994 lists Leadbeater’s Possum as endangered. This population estimate is predicted to undergo a 90% reduction by 2025. Project Possum has targeted two forest types: montane ash forest (i.e. This Fact Sheet provides key information on Leadbeater’s Possum and the threats to its habitat. [9] It was not discovered until 1867 and was originally known only through five specimens, the last one collected in 1909. The lowland floodplain forest habitat used by Leadbeater’s Possum at Yellingbo covers approximately 181 ha, however less than 20 hectares of this area currently provides suitable habitat conditions (D. Harley 2014, pers. [citation needed]. [26], Despite a joint federal and state government plan to save it, since the 1980s, the Leadbeater's possum population halved to around 2000[citation needed] even before the Black Saturday fires. In addition there is a small isolated, genetically distinct, population protected within the Yellingbo Nature Conservation Reserve. [43][failed verification] There are no plans to release the remaining two animals despite a further two colonies of Leadbeater's possums having recently been located at Lake Mountain in remnant gully vegetation. Conservation Status The animal’s vulnerability to fire makes climate change a severe danger. P opulations of hollow-bearing trees, the key At the time she was the last captive Leadbeater’s Possum … [39] The park would protect the area between Kinglake, Baw Baw and Eildon national parks, which is also important for Melbourne's drinking water and as a carbon sink. [6] On 2 March 1971, the State of Victoria made the Leadbeater's possum its faunal emblem. [21] Consequently, in December 2012, David Lindenmayer and Zoos Victoria's threatened species biologist, Dan Harley, submitted an application to the federal government for a revision of the species status, providing evidence that it should be relisted as critically endangered. [15] Extensive searches since then have found the existing population in the highlands. [2] This lowland habitat consist primarily of Sedge-rich Eucalyptus camphora Swamp. Its distribution and numbers have varied over time, with episodic severe declines associated with extensive wildfire, notably in 1939 and 2009. Leadbeater’s Possum was first described in 1867 but by 1909 was thought to be extinct. [12], David Lindenmayer (Australian National University) has argued that the need for nest boxes indicates that logging practices are not ecologically sustainable for conserving hollow-dependent species like the Leadbeater's possum. On the eve of an ABC 4 Corner episode on "Extinction" (24 June 2019) the then Environment Minister, Sussan Ley announced that it would be re-listed as "critically endangered". In January 2010, Kasia, at the time the last captive Leadbeater's possum worldwide, died at Toronto Zoo. From its peak in the 1980s, the Leadbeater’s possum population was expected to further decline rapidly, by as much as 90%, due to a habitat bottleneck. To make matters worse, bushfires tore through Victoria in 2009, destroying about 40% of the possums’ habitat and halving the possum’s wild population. Leadbeater's Possum confirmed colonies within Central Highlands RFA The Leadbeater's Possum Advisory Group (LBPAG) established in 2013, was tasked with developing recommendations (actions) to support the recovery of Leadbeater's Possum (LBP) while maintaining a sustainable timber industry (LBPAG Recommendations Report, January 2014). A guide to all 27 species of Australia's possums and gliders In 2013, the independent Leadbeater's Possum Advisory Group made recommendations to support the recovery of the possum… [10][11] From that time on, the fear that it might be extinct gradually grew into near-certainty after the swamps and wetlands in Australia around Bass River in south-west Gippsland were drained for farming in the early 1900s. Healesville Sanctuary currently holds a number of possums and is attempting to breed them. Sept. 14, 2017 - This critically endangered Leadbeater’s possum is the 7,000th species to have its portrait taken by Joel Sartore as part of National Geographic’s Photo Ark project. Leadbeater’s Possum is a small marsupial restricted to an area of about 3000 km2 in the Victorian Central Highlands and a lowland swamp forest at Yellingbo. Leadbeater’s Possum is listed under the Victorian Flora and Fauna Guarantee Act 1988 as threatened. We are also working with our partners to restore their habitat. 2010 Kasia died peacefully in her sleep at just over 10 years of age at Metro Zoo, Toronto Canada. Of its ash forest habitat, about 30% is protected, while the rest is allocated to logging. Leadbeater's Possum fact sheet - (PDF) Zoos Victoria's is fighting to save the Lowland population of the Leadbeater's Possum from extinction. [3] It is primitive, relict, and non-gliding, and, as the only species in the petaurid genus Gymnobelideus, represents an ancestral form. As a primary predator of tree-dwelling insects, the possum limits the insect influence in the ecosystem (Smith, 1995). [citation needed], Through a joint community/government program, "Project Possum" has installed approximately 200 plastic nest boxes in the wild. [19] In addition, female Leadbeater's possums are more aggressive in nature, often engaging in frequent fights with other females, including their own daughters. the required habitat for Leadbeater’s Possum for the next 150 years. The population has dropped sharply since 1996. Leadbeater’s Possum and its primary forest habitat, the Mountain Ash forests of the Central Highlands of Victoria, are both Critically Endangered. Leadbeater’s Possum is an arboreal (tree-residing) marsupial. He emphasised the need to relaunch a breeding program. After carefully considering the advice of the independent Threatened Species Scientific Committee and submissions from experts and the community, Minister Hunt decided in April 2015 to uplist the Leadbeater’s Possum to critically endangered. The species was named in 1867 after John Leadbeater, the then taxidermist at the Museum Victoria. The logging in 1993 of "much of the possum's habitat, known as zone one" a five hectare reserve east of Powelltown, followed a "mapping error". From its peak in the 1980s, biologists expected the Leadbeater’s possum population to further decline rapidly, by as much as 90%, due to a habitat bottleneck. Twenty years of monitoring across 175 sites in the Mountain Ash Forests has shown that the Leadbeater’s Possum has declined by almost two thirds over the last twenty years, while the Greater Glider population has halved within the region in the last ten years. Discover more about local conservation events and join the growing number of wild activists taking action for local wildlife. Plant exudates make up 80% of their energy intake, but the protein provided by the arthropods is essential for successful breeding.[16]. Colonies have one monogamous breeding pair, that may produce up to two young each year. As a result, Leadbeater’s possum is classified as Critically Endangered (CR) species on the IUCN Red List. Zoos Victoria's is fighting to save the Lowland population of the Leadbeater's Possum from extinction. [citation needed], Previously feral cats had only been considered a peripheral threat to Leadbeater's possums, but recent research has found video evidence of cats preying on possums leaving nesting boxes, and of possum remains in stomach contents of trapped feral cats. 8:06 AM. In Victoria, Leadbeater's Possum is listed as a threatened taxon on Schedule 2 of the Flora and Fauna Guarantee Act1988. The species is found only in Victoria, and lives primarily in the ash forests and sub-alpine woodlands of Victoria's central highlands, with a small lowland population to the east of Melbourne. The nest boxes are routinely checked for habitation every one or two years. comm. Leadbeater's possum (Gymnobelideus leadbeateri) is an endangered species of Australian possum.They need food all year round, and trees with holes where they can hide during the day. Most litters are of one or two young, which stay in the pouch for 80 to 90 days, and first emerge from the nest following this. The evolution of leadbeater possum had begun 20 million years ago. Microsatellites were cloned and optimised during this study (Hansen et al. They live in mixed-age wet sclerophyll forest with plenty of Acacia.. [42] One animal has since died. It is a non-gliding possum. An additional 50 nest boxes are due for installation in 2015–16. 2,3 Colonies of up to 12 animals spend about 75% of their lives nesting inside large trees that are 150-400 years old. Since then it has been recorded at approximately 300 localities, over an are… Nest boxes located in the sub-alpine woodland tend to have a high uptake, while those located in montane ash forest have very limited uptake. [4], The combination of 40-year-old regrowth (for food) and large dead trees left still standing after the fires (for shelter and nesting) allowed the Leadbeater's possum population to expand to an estimated peak of about 7500 in the early 1980s. [36][37], On 22 April 2015, Greg Hunt, the Minister for the Environment, announced that the Leadbeater's possum would be listed as a "critically endangered" species under the EPBC Act.[22]. Leadbeater's Possum inhabits dead and decaying trees, many of which are filled with abundant insect populations. Current Species Status: Endangered (Schedule 1, Endangered Species Protection Act 1992, IUCN Red List of Threatened Animals 1994, ANZECC 1991, CNR 1995). Young, newly independent Leadbeater's possums are very vulnerable to owls. That may not sound that exciting at first, but this possum, a Leadbeater’s possum, was supposed to be extinct. Many more were killed early in 2007 when the government-backed enterprise company, VicForests, bulldozed large firebreaks through Leadbeater's monitoring stations following the Christmas fires – firebreaks and clear-felling also prevent breeding with nearby colonies. It was first described by western scientists in 1867, and they even […] This number has now risen to over 600 new colonies. Leadbeater’s Possums use their club-shaped tails to carry bark to build their nests. From its peak in the 1980s, biologists expected the Leadbeater’s possum population to further decline rapidly, by as much as 90%, due to a habitat bottleneck. This figure includes those colonies that were detected between 1998 - 2014 and those that have been found in targeted surveys since 2014. 6mins 19secs Leadbeater's Possum population crashes by two thirds in past 20 years: report 12mins 10secs Maggie Beer on using food to fight Alzheimer's . Their findings show that the availability of suitable habitat is critical: forest must be neither too old nor too young, with conservation efforts for Leadbeater's possums involving protection of remaining old-growth stands, and maintenance of younger stands that are allowed to attain hollow-bearing age. within the range of Leadbeater’s Possum, the majority of which is ash forest (96%), with only 4% Snow Gum woodland. A colony usually consists of a single breeding pair and young or adult offspring that have not With 43% of its known Central Highlands habitat[20] destroyed in the bushfires of February 2009 – large areas of forest around Toolangi, Marysville, Narbethong, Cambarville and Healesville – the species' status is currently in doubt. [8][13] Then, on 3 April 1961, a member of the species was rediscovered by naturalist Eric Wilkinson in the forests near Cambarville, and the first specimen in more than 50 years was captured later in the month. Zoos Victoria is working to establish a captive insurance population that can support reintroduction to the wild. [12] Particularly, the February 2009 Black Saturday bushfires destroyed 43% of Leadbeater's possums' habitat in the Central Highlands, halving the wild population to 1,500. The Leadbeater’s Possum is a charismatic and iconic Australian possum and the faunal emblem of Victoria. Solitary Leadbeater's possums have difficulty surviving: when young males disperse at about 15 months of age, they tend either to join another colony as a supernumerary member, or to gather together into bachelor groups while they wait to find a mate. Leadbeater's Possum population numbers There are 688 known Leadbeater's Possum colonies protected in Victoria's State Forests. Denning groups of Leadbeater’s Possum (often referred to as ‘colonies’) typically consists of two or three individuals (Leadbeater’s Possum Advisory Group 2014), although larger colonies have been recorded in the past (up to 12 individuals). [17], Leadbeater's possums are rarely seen as they are nocturnal, fast-moving, and occupy the upper storey of some of the tallest forest trees in the world. Maggie Beer on using food to fight Alzheimer's. DKP Harley , MA Worley and TK Harley 27(1) pp.7 - 15 Number left in the wild: Fewer than 40 of the Lowland population. On 22 April 2015, it was decided to relist the species as critically endangered. The endangered Leadbeater's Possum is Victoria’s faunal emblem. The Leadbeater possum (Gymnobelideus leadbeateri) is one of the rarest subspecies. [28], Salvage logging since the fires has posed a further risk to this extremely diminished population[29] with clear-felling also approved by VicForests in the few remaining unburnt areas, such as the Kalatha Creek area of Toolangi State Forest in 2010, a move opposed by the Yarra Ranges Shire Council. [18] They live in small family colonies of up to 12 individuals,[11] including one monogamous breeding pair. However, the availability of suitable habitat is critical: forest must be neither too old nor too young, with conservation efforts for Leadbeater's possum involving protection of remaining old-growth stands, and maintenance of younger stands that are allowed to attain hollow-bearing age. The endangered Leadbeater's Possum is Victoria’s faunal emblem. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Highland populations of Leadbeater’s possums are found further east, in the tall, wet forests of Victoria’s Central Highlands. [23], As the species is endangered and occupies a restricted range,[24] logging continues to pose a critical threat to the Leadbeater's possum. We are applying emergency recovery measures for the last lowland population that now contains fewer than 40 individuals and is at very high risk of extinction. Mt Ritchie, Dowey Spur, Ben Cairn) and sub-alpine woodland (i.e. The Leadbeater's population, before the fires of 2009, numbered between 2,000 and 2,500 individuals. First found in Gippsland, Leadbeater’s Possum is now restricted to Mountain Ash or sub alpine woodland in Victoria’s Central Highlands. The loss of hollow-bearing trees is the possums' biggest threat. The Leadbeater’s Possum Advisory Group and has provided recommendations to the Victorian Government on ways to support the recovery of the Leadbeater’s Possum while maintaining a sustainable timber industry. Hollows can take 150 years to develop in living trees, and old trees with suitable hollows have decreased due to logging and bushfires. The distribution and abundance of Leadbeater's possum Gymnobelideus leadbeateri in lowland swamp forest at Yellingbo Nature Conservation Reserve. Donate if you can. [7][8], Leadbeater's possum is thought to have evolved about 20 million years ago. Population Trend: Decreasing. The Leadbeater’s Possum is a priority for Zoos Victoria.
