Research suggests there is no “safe number” of brumbies that will avoid harm to mountain ecosystems.
Failing to cull feral horses in Kosciuszko National Park may end up promoting environmental destruction while actually increasing the horses' suffering.
Gould’s goanna is commonly eaten in Indigenous communities, but can contain high levels of rat poison.

Rat baits are widely used to keep rodent pests at bay. But many Australian reptiles are resistant to the poison, potentially spreading these deadly compounds up the food chain.
Japanese knotweed in flower.

It's nearly impossible to kill, so we need to start working with Japanese knotweed to control it.
A massive wildfire on the Garden Route fuelled by invasive alien trees.
Invasive alien species that costs South Africa's economy billions can be eliminated.
An adult Halyomorpha.
An invasive insect native to Asia, Halyomorpha halys, has been detected in the US, Canada and southern Europe. It’s now made its debut in Paris.
Cane toads have been found from Perth to Sydney.
DEPARTMENT OF PARKS AND WILDLIFE/AAP
New cane toad traps that carefully imitate mating males successfully target breeding females. Males, meanwhile, will turn up for anything that sounds remotely like a toad.
The leaf-feeding beetle Zygogramma bicolorata is one of the most promising agents used against famine weed in South Africa.
Famine weed spreads rapidly and is devastatingly destructive. Biocontrol is one way of dealing with the problem.
The Cane Toad has caused irreversible change to cultural practices of certain communities in Australia.
In richer countries, the socio-economic impact of invasive species can be tackled through technology or adaptive behaviour. But this isn't the case in poor countries.
Dogs and cats spread their fleas to many other species.
Everywhere humans go, we take our pets. Fleas are along for the ride, spreading everything from typhus to bubonic plague.
Bed bugs make us shudder and cringe. So arm yourself with the courage to learn about the biology and successes of Cimex lectularius -- as well as the ways to get rid of it.
Life’s not such a beach for Galapagos native species these days.
More than 1,500 introduced species have been recorded on the Galapagos Islands, and most have arrived since the archipelago's tourism industry was expanded in the 1970s.
Wild horses, known as brumbies, in Australia.
From 30,000-year-old cave paintings to The Man From Snowy River, wild horses have always been part of human culture. As Australia debates what to do with 'brumbies' in mountain environments, it's time to reconsider their place.
Japanese vessel washed ashore on Long Beach, Washington being inspected by John Chapman.
As well as thousands of deaths and huge destruction, Japan's 2011 tsunami carried potentially invasive species _en masse_ across an entire ocean.
Bacteria cultured from a sample of air in a public building.
When jetting off on holiday, we rarely give a second thought to what microbes we might be taking with us. But humans spread trillions of bacteria around the globe, potentially harming ecosystems' balance.
Invasive pine trees in the Western Cape have affected lizards causing their numbers to drop significantly.
Invasive plants have an impact on native species and unless these factors are properly understood, it is difficult to predict what sort of impact invasive plants will have.
The aquatic weed water hyacinth is causing major problems in Ethiopia’s Lake Tana.
Lake Tana in Ethiopia has been massively affected by the invasive weed, water hyacinth. Control methods are available but there are challenges.
Guam’s trees are struggling without the birds that spread their seeds.
Guam's trees are in trouble, thanks to the accidental release of a snake species 70 years ago, which has killed off many of the bird species that are vital for the health of the island's forests.
Gene drives aim to deliberately spread bad genes when invasive species such as mice reproduce.

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
Feral pigs are found in every state and territory in Australia.
Swine brucellosis is spreading from Queensland into New South Wales. It's carried by feral pigs and poses a real risk the people and dogs that hunt them.
Invasive frogs can have a major impact on the environment. Some move continents by human trade or travel. But determining how to control them can lead to policies that limit their spread and effects.
