... characteristics required by tiger quolls. There is reasonably compelling evidence that 1080 poison baiting can cause substantial reductions in tiger quoll populations and poison baiting is likely to be at least partly responsible for the species' decline. There are no data to support competition or predation...

... A clearly-articulated paradigm is described that guides much current research-based conservation effort. This paradigm, which uses a reductionist approach, provides a method for unambiguously identifying threats to biodiversity, such as causes of species' declines, and a method...

... In Queensland since 1978, seven species of frogs have disappeared and populations of another four have seriously declined. All the declines have occurred in upland rainforest and all the species live along or breed in streams. We ask the question “what is wrong with upland rainforest streams...

... We reviewed published, quantitative studies examining the effects of exotic plants in native vegetation on the species richness and abundance of birds and mammals. We asked whether the incursion of exotic plants into native vegetation has led to consistent declines, increases or no changes...

... The Northern Territory has 36 species of bats including three fruit-bats. For each species we provide a distribution map as well as descriptions of their ecology that is relevant to their conservation and management. With one exception ( Hipposideros diadema inornatus ), all bat species have...

... regionally extinct and another 60 species continue to decline in abundance and or distribution. The critical requirement is to put back substantial amounts of appropriate habitat. Current revegetation efforts, however, are inadequate. The vast majority of revegetation effort produces patches of new...

... In the mid to late 19th century, New South Wales passed laws protecting from over-hunting just a few native bird and mammal species, despite scientists having documented the disappearance and decline of once-common species. As public concern grew over the decline of useful or commercially...

... Wales, numerical declines at regularly-visited camps, continuing loss of habitat, and culling. Listing the Grey-headed Flying-fox as a Vulnerable species triggers the need for preparation of a Recovery Plan. By having regard to the biological, social and economic consequences of making the plan...

... of abundance were not recorded over the entire period of the study, there was an apparent decline in the number of stream frogs, while the numbers of most species that breed in ponds and ephemeral situations appear to have remained unchanged. To understand the causes of the disappearances and declines...

.... We review species-based studies and conclude that assessments of demographic trends are more effective than surveys in determining impacts, and providing early warning of declines because they highlight threatening processes. Furthermore, risk analysis, when critical aspects of the biology...

... In Australia, invasive terrestrial pest species have been implicated in the decline of a number of threatened species. Under the NSW Threatened Species Conservation Act 1995 , pest threats can be listed as Key Threatening Processes which require the preparation of Threat Abatement Plans...
