Koalas are stressed out by a range of pressures, from habitat loss to dog attacks.
Ever feel so stressed you can't carry on? You're not alone - koalas have a similar problem, and hundreds are being rescued by veterinarians each year.
This quenda seems to have been a victim of land clearing.
More than 50 million birds, mammals and reptiles are thought to be killed each year in New South Wales and Queensland by the removal of native vegetation, and planning laws are failing to protect them.
Are we in the middle of a mass extinction caused by Homo sapiens? Past events can help us to understand the current crisis.
Land reform is thought to have caused the cheetah numbers to fall by 85% in Zimbabwe.
The land reform programme in Zimbabwe has come at the cost of wildlife and opens up the debate on people versus nature. But there is a way forward.
The birds commonly seen in urban backyards of Australia are increasingly introduced species like this house sparrow, sharing a birdbath with a native red-browed finch.
We all know how vital it is for our native bird species to thrive. But what if the only birds that visit your garden are introduced "pest" species? Many people feel these birds deserve some love too.
When species are pushed to the top of the mountain, where else is left to go?
From luxuries like champagne to the very livelihoods of fishing communities in the developing world – the climate-driven shifts in species will affect us all.
The human footprint on Australia’s environment is evident in areas such as land use change.
Ryan Francis/State of the Environment 2016
The State of the Environment 2016 report shows that the main drivers of environmental change in Australia are land-use change, habitat destruction, invasive species and climate change.
The Simien mountains in Ethiopia are one of the world’s most threatened natural heritage sites.

You'd hope we wouldn't flatten the pyramids to build a highway. But that's exactly what's happening to the world's natural heritage sites.
Cleared habitat in Niassa Reserve, Mozambique.
Since 1992, an area of land two-thirds the size of Australia has been converted to human use.
Sea turtles have been around for 150 million years, but today’s pace of climate change represents an existential challenge.
Climate change and tourism development in Mexico are altering the country's shoreline, endangering the habitat of sea turtles. But tourists prefer pristine, natural beaches, too.
Cheetahs have extraordinarily low genetic diversity, placing them at risk.

Wildlife in wilderness areas have more genetic diversity, which is better for their survival.
As temperatures rise, will species have enough habitat to move to suitable ground?
Animals and plants will need escape hatches to move to cooler climes as the planet warms, but few parts of the U.S. have the natural habitat available for these migrations.
New research explains why habitat loss means male willow warblers now outnumber females – and that's bad news for the species.
Koalas face many threats, and our conservation efforts are failing them.

Koalas are under threat from a range of factors, from urban expansion to climate change. Unfortunately there is no quick fix, and it may be that not all populations can be saved.
Worth crowing about? Birds that can problem-solve do best in cities.
Why are our cities full of crows, ravens and rainbow lorikeets, while other species decline? The answer comes down to street smarts, adaptability, and sometimes plain bullying.
Frogs in the Western Cape area of South Africa are susceptible to climate change.
Climate change may threaten the survival of the Cape frog. The solution could lie in creating corridors for them to move to new habitats and more suitable climate spaces.
Species lost from the eastern forests of the U.S. – from left to right: Ivory-billed Woodpecker, Passenger Pigeon, Carolina Parakeet and Bachman’s Warbler.

The extinction threat you haven't heard of: several South American birds teeter on the brink of existence due to habitat loss. And history is not the best guide for how to save them.
Clinging on: Carnaby’s black cockatoo has already lost much of its habitat.
Plans for managing Perth's rapid urban growth have been touted as green. But they still look like robbing the iconic Carnaby's black cockatoo of yet more crucial habitat.
The core habitat of the notorious chacma baboon is becoming smaller due to human takeover.
The iconic southern African Chacma baboon is in danger. The species is facing a population decline.
Squirrel gliders aren’t at risk, and hands-on conservation can keep them that way.

We're familiar with the idea of releasing almost-extinct species into new areas. By doing the same with common animals, we can help stop their population numbers getting into the same perilous state.
