Hundreds of large old trees were removed when the Hume Highway was widened.
When the Hume Highway was widened, hundreds of nest boxes were installed to replace habitat for three threatened species. Four years of monitoring has concluded the program is entirely unsuccessful.
Dingoes can help manage devastating red fox and feral cat numbers, but only if we let enough of them live in key areas.
Dingoes and wolves can help control destructive smaller predators, new research shows, but only if we encourage them across wide areas.

The impact of plant disease may be reduced if people are made aware of the many pathways for plant-killing microbes -- and why preventing their spread matters to us all.
Biodiversity keeps declining despite lots of accumulated knowledge and numerous international and national commitments to act.

Using the army to fight illegal resource exploitation aggravates conflict.

Primate populations are declining around the world. The great apes are in danger of disappearing, and that bears a great risk for humanity itself.
Bald eagles are the best-known example of a successful recovery under the Endangered Species Act.
Critics say the Endangered Species Act does not work because only about 1 percent of protected species have officially "recovered." Two biologists explain why recovery is so hard to define.
The region faces some of the world's highest rates of habitat loss, as well as direct over-exploitation of species.
Cities today are flooded with light and we seldom think of its harmful impacts on the natural world.
Urban greening programs need to consider the harmful impacts of artificial lighting on ecosystems. Fortunately, we can do a lot to create more biosensitive lighting.
There might have been as many as 160,000 types of dinosaur, give or take.

Some animals love living in the urban jungle – but they are a small minority, compared to those we risk losing to urbanisation.
Researchers have found that dragonflies have become on average lighter-colored over the past half-century in response to higher temperatures.
Study shows the footprint of climate change is already vast and that species are trying to adapt to rising temperatures.
Rainforests sustain stunning numbers of insect species, such as this Horny Devil Katydid from Ecuador.

The organisms that we're now discovering are often more hidden and more difficult to catch than ever before.
Not your average starling.
Metallic starlings – not the kind that live in your roof – breed in huge colonies that draw thousands of animals.
