A Corridor to Where?

By Carina Wyborn

Connectivity conservation has been framed as a positive contribution that individuals can make in the face of the dual crisis of biodiversity loss and climate change. What is it and why should we pay attention?

To Monitor or Not to Monitor

By Eve-McDonald-Madden

At its heart, good environmental monitoring needs a clear justification for acquiring information in the first place. What we strive to know should be driven by what we need to know.

Dr Eve Macdonald-Madden is a Key Researcher with the National Environmental Research Program Environmental Decisions Hub (NERP ED). NERP is funded by the Australian Government. NERP ED forms part of the Environmental Decisions Group.

Efficiency vs Sufficiency in Conservation

By Hugh Possingham

Comparing how much money is needed to ensure a conservation outcome with how to deliver the biggest outcome for a fixed investment are two sides of the same coin.

A World of Difference?

By Hugh Possingham

Conservation science, management and policy confront the same problems around the world. Claiming that Australia is different is not a valid excuse for not getting on with the job.

Having recently returned from a whirlwind trip through Asia, I am prompted to ask: just how much difference is there in conservation issues around the world? Before I left I would have predicted that Asia, given cultural and language differences, would be far more different than North America or Europe. I was wrong.

The first obvious difference travelling from Australia to Asia is crossing Wallace’s Line. Suddenly the species change a lot: honeyeaters become sunbirds, marsupials become placentals, and eucalypts essentially disappear (except for the ones that have been planted).

Evidence-based Conservation Could Be NICE

By Hugh Possingham

Conservationists need to take some cues from evidence-based medicine to determine the most appropriate strategies.

Evidence-based conservation, like evidence-based medicine, sounds like a no-brainer – of course our conservation actions should be based on evidence of what actually works. But just because an action is demonstrated to work it doesn’t mean it is the most appropriate management option for a particular species or place. For evidence-based conservation to better inform management it needs to factor in cost.

Species vs Landscape: A False Dichotomy

By Hugh Possingham

It’s not a question of focusing on landscape or species, because they’re inseparable. You can’t conserve the landscape without accounting for what’s happening at the species level.

Recent events might lead us to believe that single species conservation is dead, and that landscapes rule. A move to landscape-scale conservation is driven by the supposed failure of single-species conservation.
