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.

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.
