Just one out of a possible 775 development approvals was refused on the basis that it would harm the southern black-throated finch, despite this endangered species being protected by federal law.
Woolly monkeys are hard to miss in Colombia’s jungles. Now, they face extinction.
Colombian researchers hope to revive an endangered species by rehabilitating monkeys confiscated from smugglers. The captive animals' struggles show that survival is not guaranteed.
A kangaroo finds refuge in a small patch of vegetation surrounded by a new housing estate.
Expanding cities and farmland have created many small, often isolated patches of vegetation. Long seen as having limited ecological value, a new study shows these are vital for endangered species.
The burrowing owl was once a common sight on the prairies. Now Saskatchewan and Alberta have fewer than 1,000 breeding pairs.
Carving up ecosystems or opening them to development puts the survival of species at risk.
Like many migratory songbirds, tree swallows are experiencing population declines in parts of their breeding range.
Effective conservation of migratory songbirds requires an understanding of how populations are connected between seasons. The challenge is being able to track individuals throughout the entire year.
Eyes in the sky: drone footage is becoming a vital tool for monitoring ecosystems.

Ecology is in the midst of a technological revolution. From tiny sensors that can be fitted to animals, to swarms of remotely-piloted drones, researchers have a host of new ways to study the natural world.
Tundra swans, which nest in the Arctic and migrate south in fall, alight at Mattamuskeet National Wildlife Refuge in North Carolina.
The Interior Department is narrowing protection for migratory birds to cover only deliberate harm such as hunting, but not threats like development or pollution that kill millions of birds yearly.
Sudden droughts are bad news for political stability worldwide.
A new international report makes for bleak reading on the state of the world's soils. It predicts that land degradation will displace up to 700 million people worldwide by mid-century.
A giant swallowtail butterfly feeds from the flower of an alternate-leaved dogwood.
We're in the middle of an Insectageddon. But a garden of native plants can help insects, as well as birds and other wildlife.
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.
