Population drops by more than 80pc since mid 1980s
The Leadbeater's possum, Victoria's faunal emblem, has been declared critically endangered by Federal Environment Minister Greg Hunt, with the population plunging by 80 per cent over the past 30 years.
Professor David Lindenmayer, who has been researching the animal for more than 30 years, said the main threat to the possum's habitat was logging and fire.

Australian cities can keep their precious koalas from ending up as road kill – if they plan their roads properly, environmental scientists say.
A new study at the ARC Centre of Excellence for Environmental Decisions (CEED) reveals that expanding existing highways, instead of building new roads, is the best way to minimise the impact of increasing traffic and growing cities on koalas.
“The impact of roads on wildlife is growing rapidly as we continue to expand our cities,” says Dr Jonathan Rhodes from CEED and The University of Queensland (UQ). “Animals worldwide, including mammals, birds, reptiles and frogs, are increasingly threatened by high traffic volumes.”
International scientists have urged the three nations who share the Asian island of Borneo to collaborate more closely to save their endangered wildlife and meet development goals.
By coordinating conservation and development efforts as well as reforming land-use, Malaysia, Indonesia and Brunei could retain up to half of the land of Borneo as forests, protect elephant and orangutan habitats, reduce carbon dioxide emissions by 50 per cent, and possibly significantly reduce the opportunity costs by billions of dollars.
The study, published in the scientific journal Nature Communications, is led by researchers at the ARC Centre of Excellence for Environmental Decisions (CEED).
“Borneo is the world’s third largest island – it harbours over 14,000 plant species and 1,600 land animals,” says lead author Ms Rebecca Runting of CEED and The University of Queensland (UQ). “These tropical forests regulate regional and global climate and provide food and income to millions of people.”
Ms Runting explains that the high rates of forest conversion and degradation over previous decades have prompted the three nations to pledge to protect their natural resources, including maintaining between 45 and 75 per cent of the land area of Borneo as forests. At the same time, Malaysia and Indonesia have planned to greatly expand the area of oil palm and timber plantations.
The study reveals that the governments’ current land-use plans are inadequate, and will fall significantly short of meeting their conservation goals.

Preventing Australia's biodiversity from collapsing needs long-term science-based programs which are more complex than just culling cats and foxes, says environmental scientist Professor David Lindenmayer, from the Australian National University (ANU).
Chris Pash from Business Insider Australia writes about Professor Lindenmayer' recent commentary in the latest PNAS journal where he states that short term programs could sometimes be ineffective or even detrimental to endangered species.
A simple test of the amount of fish living on a coral reef can be used as a guide to restore degraded reefs and fishers' livelihoods, according to a paper published in the scientific journal Nature.
An international team of marine scientists, including CEED's Dr Joseph Maina, surveyed over 800 coral reefs worldwide, developing a mathematical model to test the health of a reef and the time it would take to recover.
They found that reefs being fished without any fishing restrictions are in deep trouble, with the vast majority of them missing more than half their total fish biomass.

To address the global extinction crisis, both efficient use of existing conservation funding and new sources of funding are vital. Private sponsorship of charismatic ‘flagship’ species conservation represents an important source of new funding, but has been criticized as being biased and inefficient. In this study, we clearly show that private funding for flagships can often result in additional species saved from extinction, via conservation actions that are shared among species. By integrating sponsorship for flagships into more objective approaches that maximize shared benefits, and by using flagships to generate additional resources, more species can be saved from extinction.

The world may need to allow controlled trophy hunting of elephants, lions and other animals if it wants to keep its endangered wildlife, an environmental scientist says.
Dr Duan Biggs of the ARC Centre of Excellence for Environmental Decisions (CEED) and The University of Queensland (UQ) argues that trophy hunting of elephants and lions – managed well – is critical for the well-being of local communities in low income countries, and the successful conservation of the animals and their habitats in turn.
Dr Biggs says managed hunting means that only carefully selected animals such as old or dying animals are hunted to ensure sustainability, and only allowing the export and import of trophies from operators that follow best practices.
Without this, he warns, poaching and illegal trade in wildlife products will thrive, as impoverished local communities have no incentive to protect the animals, and may even be driven to poach them or join the illicit trade.

SAVING CRITICALLY ENDANGERED VERTEBRATES IS POSSIBLE, BUT REQUIRES URGENCY AND INVESTMENT
A paper published today in Current Biology concluded that immediate conservation action and an investment of an estimated US$1.3 million per species will significantly increase the chances of survival for vertebrates on the brink of extinction.
The paper was published by a multi‐disciplinary research team led by Dr Dalia A Conde and Prof John E Fa from Imperial College London (formerly at Durrell Wildlife Conservation Trust), along with Prof Hugh Possingham from CEED and the University of Queensland, and scientists from the Max‐Planck Odense Center at the University of Southern Denmark, Texas A&M University, American Bird Conservancy, IUCN SSC Conservation Breeding Specialist Group, International Species Information System and World Association of Zoos and Aquariums.

Poaching, in particular of big, charasmatic game such as Rhino and Elephant a major threat to the existance of these species.
In this YouTube video, CEED Researcher Dr Duan Biggs and Jacob Phelps (Center for International Forestry Research - CIFOR) discuss contentious policy responses to the booming illegal trade in wild plants and animals. When are sustainable use and captive breeding viable options, and what are their limitations?
The world needs to rethink its approach to conservation if it is to save nature from a looming wave of extinctions.Researchers from the ARC Centre of Excellence for Environmental Decisions (CEED) say the focus on 'threat hotspots', a strategy used by many countries and conservation bodies, can be expensive, inadequate and may even push threatened species closer to the brink.
In a review published in the journal Frontiers of Ecology and the Environment headed up by Dr Ayesha Tulloch, the researchers propose a new framework that helps identify conservation actions that are both affordable and achieve have the greatest benefit for imperilled animals and plants.
