Since European occupation of Australia, human activities have caused the dramatic decline and sometimes extinction many continent’s unique species. Here we provide a comprehensive review threats to species listed as threatened under Australia’s Environment Protection Biodiversity Conservation Act 1999. Following accepted global categories threat, find that invasive affect largest number (1257 species, or 82% all species); ecosystem modifications (e.g. fire) (74% species) agricultural...
Land clearing threatens biodiversity, impairs the functioning of terrestrial, freshwater, and marine ecosystems, is a key contributor to human-induced climate change. The rates land in State Queensland, Australia, are at globally significant levels, have been subject intense polarised political debate. In 2016, legislative bill that aimed restore stronger controls over failed pass Queensland Parliament, despite clear scientific basis for policy reform. Here, we provide short history recent...
Abstract Australia is in the midst of an extinction crisis, having already lost 10% terrestrial mammal fauna since European settlement and with hundreds other species at high risk extinction. The decline nation's biota a result array threatening processes; however, comprehensive taxon‐specific understanding threats their relative impacts remains undocumented nationally. Using expert consultation, we compile first complete, validated, consistent threat impact dataset for all nationally listed...
Questions: Does species richness and abundance accumulate with grazing protection in low productivity ecosystems a short evolutionary history of grazing, as predicted by emerging theory? How do responses to inform degradation history? Location: Mulga (Acacia aneura) dry forest, eastern Australia, generally considered chronically degraded livestock grazing. Methods: Three paired exclosures (ungrazed, macropod-grazed) were compared open-grazed areas after 25 years using quadrats located on...

Even when no baseline data are available, the impacts of 150 years livestock grazing on natural grasslands can be assessed using a combined approach manipulation and regional‐scale assessment flora. Here, we demonstrate efficacy this method across 18 sites in semidesert Mitchell northeastern Australia. Fifteen‐year‐old exclosures (ungrazed macropod grazed) revealed that dominant perennial grasses genus Astrebla do not respond negatively to disturbance typical commercial pastoralism. Neutral,...
A chief tool in plant conservation is the augmenting or establishment of threatened populations by translocating individuals grown ex-situ. As translocations become an increasingly common practise and land management, various techniques to increase survival persistence have established as standard. Here we use a large historical database evaluate evidence for management enhance translocation performance. We found that most important factors associated with maximising size translocated were...
The prevalence and imperative of translocations for the conservation plant species is increasing in response to habitat loss degradation, diseases, projected climate change. However, intentional movement nurture increase their range and/or abundance has been practiced millennia, encompassing with food, medicinal, narcotic, ceremonial values. While it well documented that Australian Aboriginal people altered composition structure vegetation communities through regular burning engaged complex...
Gypseous substrates are well-recognised as supporting distinctive and unique flora assemblages, including numerous gypsum endemic (gypsophile) species. Along with these, others also frequent although their presence is not restricted to gypsum; they show a clear preference for them (gypsocline). While this phenomenon (gypsophily) has been studied regionally, various hypotheses put forward explain it, there little global synthesis. We present preliminary check-list on the gypsophile gypsocline...
Lack of basic data to assess plant species against IUCN Red List criteria is a major impediment assigning accurate conservation status throughout large areas the world. Erroneous assessments will be most prevalent in vast poorly surveyed where herbarium collections are sparse. In arid environments, further confounded by extreme temporal variability and poor understanding nature magnitude threats. We systematically re-assess an arid-zone flora. The all 1781 vascular occurring across 635 300...
Threatened species lists are used at global, national and regional scales to identify risk of extinction. Many listed due restricted population size or geographic distribution, decline is often inferred rather than quantified. Vascular plants comprise over 70% nationally threatened species, but there an incomplete picture which most extinction, where these occur the factors behind their declines. We compiled published information best available field knowledge including 125 expert interviews...
Groundwater springs are significant landscape features for humans and the biota that occupies their habitat. Many become inactive where groundwater exploitation by has lowered water table or artesian pressure. In order to assess this impact, it is important identify locate active, with more difficulty, springs. Using a variety of archival, environmental field-based data, study presents protocol determination location status across Great Artesian Basin Australia. This underpins database...
South-western Queensland supports a suite of threatened native species, including Night Parrots. We investigated why this species has persisted in the region and discovered low prevalence typical factors that are thought to explain fauna attrition elsewhere central Australia. Foxes appear be completely absent. Feral cats were recorded relatively infrequently showed significant preference for habitats less commonly used by Parrots, partition may driven presence dogs detected twice as...
Ethnohistoric accounts indicate that the people of Australia's Channel Country engaged in activities rarely recorded elsewhere on continent, including food storage, aquaculture and possible cultivation, yet there has been little archaeological fieldwork to verify these accounts. Here, authors report a collaborative research project initiated by Mithaka addressing this lack investigation. The results show substantial diverse record, numerous large stone quarries, multiple ritual structures...
Herbivore exclusion is implemented globally to recover ecosystems from grazing by introduced and native herbivores, but evidence for large-scale biodiversity benefits inconsistent in arid ecosystems. We examined the effects of livestock on dryland plant richness reproductive capacity. collected data species seeding (reproductive capacity), rainfall, vegetation productivity cover, soil strength herbivore intensity 68 sites across 6500 km2 Georgina gidgee (Acacia georginae) woodlands central...
Abstract The nocturnal, cryptic and geographically remote nature of night parrots, combined with their apparent rapid decline, means that very little is known biology or ecology. discovery a resident population in south‐western Queensland 2013 provides the first opportunity to undertake detailed studies on this most enigmatic birds. We attached radio tag bird for 20 days April 2015 GPS another 5 May 2016 study movement patterns habitat use. Both birds displayed similar behaviour but ‐tagging...
Translocation of plants is used globally as a conservation action to bolster existing or establish new populations threatened species and usually communicated in academic publications case studies. also mitigate offset impacts urbanization development but less often publicly published. Irrespective the motivation, mitigation, on ground actions are driven by overriding global goals, applied local national legislation. This paper deconstructs legislative framework which guides translocation...
Many global and national conservation initiatives have objectives relating to reducing or reversing the rate of biodiversity decline but few specific targets. In 2015, Australian Government implemented a Threatened Species Strategy that aimed improve population trajectory set 71 species (20 mammals, 21 birds 30 plants) by 2020, relative before 2015. To assess extent which this objective had been achieved, because there was no limited monitoring for many species, we used structured expert...
Context Understanding historical distributions of species informs their ecology and response to threats, which can support management surviving translocated populations. Like many critical weight-range mammals in Australia, the greater bilby (Macrotis lagotis) has experienced major declines since European colonisation. The past distribution bilbies eastern Australia remains uncertain owing rapidity decline, cryptic nocturnal nature, paucity specimen records. Aims We aimed systematically...
