How to move without legs or wings: Helping trees migrate to new regions

The rapidly changing climate presents many challenges for the sustainability of forest ecosystems. Assisting the migration of trees is a tool to address these challenges.
Smouldering fire in a drained peatland near Fort McMurray, Alta. produces smoke from underground. These ecosystems are affected by rising temperatures, drought, wildfire and various human actions including drainage. (Leyland Cecco)

Up in smoke: Human activities are fuelling wildfires that burn essential carbon-sequestering peatlands

New research shows that northern peatlands may not help regulate our climate by the end of the century.
Fires are increasing in high mountain areas that rarely burned in the past. John McColgan, Bureau of Land Management, Alaska Fire Service

Fire danger in the high mountains is intensifying: That’s bad news for humans, treacherous for the environment

Fires here can affect meltwater timing and water quality, worsen erosion that triggers mudslides, and much more, as two scientists explain.
Roads require de-icing strategies in northern regions, but this practice has negative effects on aquatic biodiversity.

Freshwater ecosystems are becoming increasingly salty. Here’s why this is a concern

Although it has been considerably less studied than other environmental problems, salinization presents major challenges for biodiversity in freshwater and coastal areas.
Once abundant, woylies – or brush-tailed bettongs – are now critically endangered. John Gould

Species don’t live in isolation: what changing threats to 4 marsupials tell us about the future

To give native species their best chance of survival, we have to embrace ecosystem-based conservation – rather than trying to rescue individual species in isolation.

Good or bad? Some ‘invasive species’ can help native ecosystems thrive

Conservation practitioners and policymakers must organize and prioritize the management of habitats around whether species are more beneficial or harmful to biodiversity.

Do humans really need other species?

People wouldn’t last long without the countless other species we depend on for survival.
