What do you do when you outgrow your cage? Fences are a key strategy in the conservation of threatened native species, particularly in Australia and New Zealand. Australia has more than 37 large conservation fences, enclosing 27 species of bird, marsupial and reptile in more than 35 thousand hectares of predator-free habitat. On the Australian […]
Are two fences better than one?
Adding value when communicating data and analysis As a scientist I spend a reasonable amount of time making graphics (figures, plots, diagrams and so forth) for publication and talks. It’s a part of my job I enjoy. I use these pictures to explain how models work, demonstrate experimental design, and show results. Through this experience […]
Predicting and preventing future species invasions Invasive species cost hundreds of billions of dollars a year to the global economy, and are a major threat to native species and ecosystems. As global travel and trade accelerate, so does the transport (intentional and inadvertent) of species to new locations. Most newly-introduced species will not become invasive; […]
Multiple-actor conservation and the need for explicit coordination Systematic conservation planning is the absolute best-practice approach to conserving biodiversity in a large landscape. We create maps that highlight the distribution of our favourite conservation features – be they threatened species, vulnerable habitats, ecosystem services, or all of the above – and then we use these […]
Modeling local implementation and regional conservation planning in Fiji: In a perfect world, conservation planning would be systematic. Decisions on where to set up (and how to manage) reserves would be undertaken considering the natural values of that reserve together with how these values combine with other reserves (complementarity) and how different reserves are connected […]
Comparing the value of coordinated fisheries management Fisheries management rarely coordinates different fishing activities for different species. That’s in part because it’s a challenging and costly thing to do. But this is compounded by the difficulty of assessing whether it’s worth the effort in the first place. Comparing the value of coordinated management with uncoordinated […]
Trade-offs around extinction At current levels of funding, it is not possible to save all threatened species in Australia from extinction. You might not like that (we definitely don’t) but it is a fact of life. Indeed, to secure all species, the increase in funding might need to be tenfold (see for example McCarthy et […]
