Mixed plantings vs monocultures for carbon

When planting forests to offset carbon emissions, is it best to go with monocultures or a mix of species? Kris Hulvey and colleagues compiled and analysed data from existing forest studies to compare carbon storage in mixed tree plantings to carbon storage in monoculture plantings. They found that mixtures of tree species stored at least as much carbon as monoculture […]

When to move species threatened by climate change

Introducing species to areas outside their historical range to secure their future under climate change is a controversial strategy for preventing extinction. While the debate over the wisdom of this strategy continues, such introductions are already taking place. Previous frameworks for analysing the decision to introduce have lacked a quantifiable management objective and mathematically rigorous problem formulation. Tracy Rout and colleagues […]

Koala search

Koala genetic connectivity is driven by the ghost of landscapes past.   Koala genetic connectivity is driven by the ghost of landscapes past (see page 10,11). Isn’t it amazing what researchers can reveal with a little data, a few good questions and a bit of maths? Koalas have been the feature of many past issues of Decision Point. In Decision […]

What’s ‘feasible’ in the Solomons?

Incorporating feasibility of conservation action into planning Some of us (including me) have spent the last few years talking about how social data should be integrated into conservation decisions. It makes sense, right? Effective conservation requires people to make choices about how they interact with the environment. It’s about choices on the amount of resources they extract and how […]

Koala gene flow across landscapes

Of ghosts, fragmentation and scale-mismatches Imagine being a koala trying to move about in southeast Queensland. You are faced with double-lane highways, urban sprawl and vast amounts of cleared land; not to mention a limited supply of nutritious eucalyptus leaves. What are the relative costs of these different obstacles for a koala on the move? How do these costs influence […]

The heart of the matter

Priority threat management of invasive plants in the Lake Eyre Basin Australia’s ‘heart’ and the river systems that feed it are under pressure from multiple sources. Something needs to be done quickly but, as is often the case, environmental managers are operating under severe time and resource limitations, and are attempting to make decisions surrounded by enormous uncertainty. In […]

Being climate smart means looking forward and backward

Cost-effective conservation in a time of climate change What is ‘climate smart’ when it comes to conservation planning in a time of climate change? Part of the answer is to take into account how climate change will impact areas where conservation activities are planned. For example, you don’t want to invest your limited budget in a wetland reserve when […]
