As well as direct human impacts, Australia is seeing an increase in feral pest species that add to the pressure on our environment.

Deer management in Victoria

Sambar deer number over 1 million in Victoria. They are extremely destructive of stream sides, rainforests and understorey vegetation.
Comments on the Draft Deer Management Strategy

2nd November 2018

EEG represents 350 members and over 1000 supporters and has been active in the East Gippsland region for 35 years.

Our members have also witnessed a dramatic rise in deer numbers and have experienced the damage. We welcome a state strategy ...

Responses of invasive predators and native prey to a prescribed forest fire

Fire shapes biome distribution and community composition worldwide, and is extensively used as a management tool in flammable landscapes. There is growing concern, however, that fire could increase the vulnerability of native fauna to invasive predators.

We developed a conceptual model of the ways in which fire could influence predator–prey dynamics. Using a before–after, control–impact experiment, we then investigated the short-term effects of a prescribed fire on 2 ...

Feral cats now cover 99.8% of Australia

Feral population of up to 6.3 million, at a density of one cat for every 4 sq km ‘underlines how potent they are for wildlife’

Feral cat-free areas of Australia are limited to a few islands, of which 12 ...

The Moral Cost of Cats

A bird-loving scientist calls for an end to outdoor cats “once and for all” 

Pete Marra is haunted by cats. He sees them everywhere: slinking down alleys, crouched under porches, glaring at him out of wild, starved eyes.

People assume that Marra, head of the Smithsonian Migratory Bird Center and author of the recent book Cat Wars, hates cats. This is not the case. “I love cats,” he says, ...

Invasive predators are eating the world’s animals to extinction – and the worst is close to home

Invasive species are a threat to wildlife across the globe – and invasive, predatory mammals are particularly damaging.

Our research, recently published in Proceedings of the National Academy of Sciences, shows that these predators – cats, rats and foxes, but also house mice, possums and many others – have contributed to around 60% of bird, mammal and reptile extinctions. The worst offenders are feral cats, contributing to over 60 extinctions.

So how can we stop these mammals eating away at our threatened ...

Ending the reign of hard hooves

Getting cows, deer, horses, goats and pigs out of national parks is proving a very difficult exercise, even though the damage they do is abundantly clear, says Phil Ingamells.

When we were fighting licensed cattle grazing in the Alpine National Park, the cattlemen always asked why we weren’t arguing for control of horses and deer.

Feral species inquiry

In Victoria, a parliamentary enquiry has been set up to look at controlling invasive species on crown land. EEG is concerned there is too much focus on shooters and National Parks. Allowing shooting organisations to kill deer or foxes in the Alps or parks will hardly put a dint in their numbers (but will gain a few votes).

What’s needed is serious political will to fund research to progress ...

Ongoing unraveling of a continental fauna

Decline and extinction of Australian mammals since European settlement

The island continent of Australia harbors much of the world’s most distinctive biodiversity, but this review describes an extent of recent and ongoing loss of its mammal fauna that is exceptionally high and appreciably greater than previously recognized.

With the dwindling abundance, range, and diversity of so many species, we see now only a faint shadow of the richness and abundance of the Australian mammal fauna that existed at the time of European ...
