Gamba Grass is altering fire regimes in the Top End, threatening human life and property, natural assets including Kakadu and Litchfield National Parks, and compromising savanna burning programs.
One of the Australian government's new research priorities is "environmental change". But can be hard to know how to tackle such huge and interlinked issues as climate change and species extinctions.
Grey squirrels hate these reclusive, cat-sized predators.
If genetics are not considered when translocating lions, their evolutionary line could be affected.
Genetics need to be considered when relocating lion populations because they a play a role in the animals' evolutionary line.
This furry critter could help save plenty of others, if given the chance.

If we brought devils back to the mainland, they could play a similar role to dingoes - keeping foxes and cats under control and potentially boosting the conservation prospects of Australia's small mammals.
People in the Ruaha landscape lose their livestock as a result of predator attacks.
Human and wildlife conflict in Tanzania's Ruaha region is extremely tense. There are many projects underway to alleviate this tension.
No trophy hunters that way … or that way.
The latest trophy hunting furore should at least raise the profile of Africa’s forgotten megafauna.
Cute – but not actually endangered.
The UK has few endemic and endangered species. Wildlife protection is easier and more important elsewhere.
The killing of Cecil the lion which generated a huge uproar globally presents Zimbabwean an opportune moment to look harder at who benefits from wildlife.
The shooting of Cecil shines light on Zimbabwe's new elite land politics which excludes the wider population and exposes the racial dimensions of the relationship between wildlife, land and hunting.
We know a lot about what climate change will do, but ‘when’ is a tougher question.
What we think we know, don't know and things that might surprise us about climate change and the environment.
There’s nothing feral about this Australian wildcat.

There's been a lot of talk about killing feral cats, with the government's recently announced war on cats, with a goal to kill two million by 2020. But let's embrace cats as part of Australia's environment.
The pilot whale hunt is still largely unchanged for hundreds of years.
It's difficult to talk about whaling without emotions getting in the way. But we must.
Humpback whale populations have leapt on both Australia’s east and west coasts.

Chalk it up as a rare conservation win: humpback whales have bounced back so strongly since the whaling era that there is no longer a need to include them on Australia's official threatened species list.
Feral cats are thought to be responsible for the decline of many Australian species.
Feral cats are highly adaptable and highly variable, hence we must continue to search for their Achilles Heel and invest in a wide range of control methods.
Bison are roaming free in Germany – so why not Scotland?
Restoring natural ecosystems doesn't have to mean looking back to the past.
The basic problem facing endangered species? Too many humans.
Each new human on the planet makes extinctions more likely, yet birth control still isn't seen as a big environmental issue.
The critically endangered Leadbeater’s Possums is just one of Australia’s animals threatened by habitat loss.
Three recent reports make clear that we should be saving habitat in order to save species. It is pretty simple. Destroy a species' habitat and you destroy its home.
The government has convened 16 experts to help deliver its plan to save the Great Barrier Reef.

The government's plan to save the Great Barrier Reef hinges on hitting a series of pollution and conservation targets within just a few years. A new expert panel will advise on how best to get there.
Go with the flow: scarce water has allowed Outback species to persist for millennia, where otherwise they might have died out.
The Outback covers 70% of Australia, and its water is precious and scarce. Yet there is no joined-up plan to monitor and manage Outback water, despite the wealth of species and communities that depend on it.
Mustela erminea), feral cats ( Felis catus), red foxes ( Vulpes vulpes) and black rats ( Rattus rattus) are invasive predators in different parts of the world.

Research published this week shows saving wildlife is much more complicated than killing introduced predators. Killing predators often doesn't work, and is sometimes actually worse for native wildlife.
What do collections of dead butterflies do for their still-living counterparts?
Andrew D Warren
The dead animal specimens that comprise natural history collections contribute a lot toward scientific understanding of their still-living counterparts – and those that have gone extinct.
