Australia has around 230 species of frog but no native salamanders (newts), though salamanders have been available as pets for many years. Well, now it seems pet salamanders have broken out with the discovery of many specimens of the European or smooth newt (Lissotriton vulgaris) living wild in the outer suburbs of Melbourne. And that could have dire consequences for Australia’s aquatic biodiversity.

Late in 2013 the NSW Government adopted a version of ‘conservation triage’ that is based on our cost effectiveness approach – the Project Prioritisation Protocol or PPP. The NSW Government called their program Saving our Species and it provides a coherent framework for the conservation of threatened species.
A NERP Workshop (University of Melbourne, May 2014) By Carly Cook (MU), Kelly Hunt de Bie (UoM), and Prue Addison (UoM) Managing natural environments involves difficult decisions about when to intervene to prevent undesirable changes. Intervening too early may result in unnecessary management actions, while intervening too late may lead to much greater costs or […]
Picture your ideal city park. Perhaps it has benches, well-maintained jogging paths, plenty of green lawn space to spread out a picnic blanket. Perhaps it has a ‘wilder’ feel to it, with dense pockets of native bush and narrow dirt footpaths that allow for uninterrupted bird-watching and respite from the city bustle. Now what if no human ever visited it? Perhaps the very ‘wildness’ that appealed to you has the local residents worried about homeless folks in the bushes, and they’d rather drive to the parky-park that’s several kilometers away. But maybe they cannot go to that parky-park because they only have one car for their large family and it can’t be spared for recreation. What service does that unvisited park provide to the local residents then? What services could or should it provide?
50 years and still counting The world’s most comprehensive information source on the global conservation status of animal, fungi and plant species – the IUCN Red List – has turned 50! The Red List has proved to be a powerful tool to inform and catalyse action for biodiversity conservation. It provides information on population size […]
Knowing there is a problem and doing something about it can sometimes be entirely different things. Koalas, while much beloved by the Australian public, have been in steady decline for at least the last decade. A combination of threats like habitat loss and modification, car collisions and dog attacks, led to the koala being listed under the EPBC Act in 2012. Increasingly, more councils (and Local Government Areas) are drafting and implementing local koala management plans and developing strategies to combat losses and aid in population recovery. However, in order for these conservation goals to be effective, members of the general public must be willing to adopt the suggested actions and incorporate them into their everyday routine. How feasible is this when such a large gap exists between peoples’ intent to conserve and their actual conservation behavior? What might influence those decisions?
Technology companies have a reputation for innovation in the design of their working environments. Google, for example, is famed for outfitting its headquarters with coffee shops, slides, masseuses, funky couches, and for the 20% time policy (employees are encouraged to take one day a week to work on anything they want). The games company Valve takes this a step further by allowing their employees to be effectively autonomous (Valve 2012). Each person joins whatever project they want to join and can initiate any project of their own (the theory is that good ideas attract other people and are more likely to succeed, bad ideas die from neglect).
Conserving migratory animals has always been a challenge because they face a range of threats at different parts of their migration, often separated by vast geographical distances (consider the threat to migratory birds from the loss of tidal flats in Asia, see p8). Addressing threats to population viability of migratory animals therefore requires integrating information of how individuals move, survive and reproduce throughout their annual cycle
Who speaks for the tidal flat? There are many voices for the mangrove forest, the coral reef and the seagrass meadow, but the chorus for the mud, sand and silt flats that sit hidden under shallow water for most of the tidal cycle is often silent. Not only do hundreds of species of migratory bird depend on them for their existence, this coastal ecosystem also protects large chunks of humanity and provide ecosystem services to hundreds of millions of people around the world.
In 1907 a ‘pet’ fox jumped ship, abandoning the crew of a fishing vessel as it passed Phillip Island, and swam ashore. Lying at the entrance of Western Port, Phillip Island is home to extensive colonies of breeding seabirds including short-tailed shearwaters and little penguins. It’s also a refuge for threatened shorebirds such as hooded plovers. What a paradise this must have been for that enterprising fox! The following year there was evidence that the fox had caused the death of many short-tailed shearwaters.
