Reading desert sands – Indigenous wildlife tracking skills underpin vast monitoring project

Footprints, droppings, diggings and other signs left behind by animals reveal a lot to a skilled observer. Indigenous knowledge feeds into one of Australia’s largest wildlife monitoring endeavours.
Not all introduced species are a problem. The introduced Siberian Elm is an example of an “invasive” species which adapts well to its new ecosystem, providing benefits at the same time. (Shutterstock)

Climate change means we may have to learn to live with invasive species

Invasive species are not always harmful; some can even provide key benefits to native habitats in an era of climate change. Canadian conservation efforts should embrace the movement of species.

Invasive species are reshaping aquatic ecosystems, one lake at a time

Freshwater ecosystems in Canada, and around the world, are more fragile than they look and vulnerable to invasive species. Canada’s lakes and rivers require constant vigilance to protect from invasion.

A window of opportunity for climate and biodiversity

The United Nations Framework Convention on Climate Change and its Convention on Biological Diversity are separate platforms, but climate change and biodiversity loss urgently require a joint approach.
Land clearing in Queensland. Martin Taylor
