A nationwide outbreak of foot and mouth disease; an invasion of a devastating wheat disease; our honeybees completely wiped out. These are just three possible disastrous scenarios facing Australia; they’re…
Stink bug. As names go it is a PR disaster, each of the words alone hardly endearing, and, in combination, wholly off-putting. Which is a shame because stink bugs have a perky charm, a distinctive style…

Invasive species colonize and spread widely in places where they are not normally found. Invasives often affect native species by eating them, out-competing them and introducing unfamiliar parasites and…
Canary grass is an invasive plant, but new varieties are still being developed for pasture.

Weeds cost Australian farmers around A$4 billion every year — and they are likely to do a similar amount of damage to the environment. In a new global survey published this week in Proceedings of the National…
During a speech in Parliament on October 17 1996 — 18 years ago today — then Liberal MP Richard Evans called for the “total eradication of domestic and feral cats from the Australian mainland and offshore…

The UK’s environment agency has confirmed quagga mussels, a fresh or brackish water mollusc, have been found in a reservoir near London. Quagga were previously identified as one of the single greatest…
Rabbit numbers have been considerably reduced by the introduction of two viruses - Rabbit calicivirus and myxoma.

Australia’s “ferals” — invasive alien plants, pests and diseases — are the largest bioeconomic threats to Australian agriculture. They also harm our natural ecosystems and biodiversity. Some, such as mosquitoes…

When you think of horses in the Australia high country, you might imagine noble brumbies galloping out from snowgums across grassy peaks, tails and manes trailing like streamers. But on a recent trip to…
Feral domestic cats are a global threat to biodiversity and were recently named as the biggest threat to endangered Australian mammals. But what about your pet cat, or the local stray? While any kind of…

Britain, like many countries, has already witnessed the establishment of many non-native species of plants and animals, and about 15% have become problematic and so termed “invasive”. Some were deliberately…

A plant called “the scourge of the South” has a new strike against it. Recent research shows that the impact of the invasive species in question, kudzu, is more troublesome than had been previously thought…

Almost a third of Australia’s mammals have become extinct or are facing extinction, largely thanks to introduced predators such as cats and foxes. But what is the best way to save the species still alive…
American wolves show us how important large predators are for conservation.

We know that introduced predators such as foxes and cats are one of the greatest threats to Australia’s wildlife, but what is the best way to control them? Many Australian ecologists argue dingoes are…

Prince Charles is among those repeating their calls for an organised cull of grey squirrels in Britain as a way of helping the declining native red squirrel. Despite being larger and stronger than their…
Carp have spread throughout Australia’s waterways - but CSIRO is hoping to bring a new genetic weapon to bear on them.

A genetic modification that creates male-only populations could give us a new weapon against invasive fish such as carp that plague our waterways. “Daughterless technology”, which works by removing females…
What to do about invasive species, which are having a growing and generally detrimental effect on Europe’s environment and economies, is the subject of discussion in both the European Parliament and UK…
Dingoes offer a way to conserve Australia’s wildlife, for free.

Introduced species pose one of the greatest threats to Australia’s fauna and flora, but expensive efforts to control them aren’t working. Instead of spending millions of dollars on culling, giving dingoes…
Not a new idea, as this map from 1885 shows, but no less controversial.

The Nicaraguan government has granted a concession to a mysterious Chinese company owned by Jing Wang, a little-known Hong-Kong based businessman, to build an inter-oceanic canal. This would provide an…

As Christmas and summer holidays approach, many of us are packing our bags, ready to drive off on holidays to see families and friends. Those long car trips are often to coastal towns, national parks and…
Cane Toads have wreaked havoc in Australia. Could we predict the next invasive species?

New research on invasive species has cast doubt on the prevailing theory developed by Charles Darwin, giving us a new way to predict and model species when they are introduced. Invasive animals such as…
