Building models for better decisions

Models are basic to good decision making. System models are representations of the dynamics of an ecological system, a conceptual map of how the system works. They enable us to specify our thinking on how the system responds to management. Without them in our decision frame it’s unlikely our choices will be well founded. What’s more, and just as important, without a system model the potential to learn is limited.

Making big predictions using small data

Managing threats to communities of declining species with incomplete information Key messages: By combining models of responses to threats with network analyses of species co-occurrence, we developed an approach to predict how an ecological community restructures under threat management Information from a few species on co-occurrence and expected responses to alternative threat management actions can […]

Conservation and the Village Forest

Do community forests reduce deforestation? Community forest management has been identified as a win-win option for reducing rates of deforestation while also improving the welfare of rural communities in developing countries. But is it delivering the hoped for benefits? Despite considerable investment around the world in community forestry, there is a lack of systematic evaluation […]

One dog’s fun is another bird’s terror. Repeated disturbance by dogs can stress and even kill shorebirds. (Photo by Kiran Dhanjal-Adams)

Using maths to decide when to put dogs on leashes

Reducing the threat to our endangered migratory shorebirds Key messages: We sought the most cost-effective allocation of patrol effort among sites with a limited budget to help manage disturbances to migratory shorebirds We demonstrate a straightforward objective method for allocating enforcement effort while accounting for diminishing returns on investment over multiple visits to the same […]

The money or the trees

What drives landholders’ participation in biodiverse carbon plantings? Key messages: We developed a Bayesian Belief Network that predicts landholder participation rate for any type of carbon-farming scheme We found that program characteristics are more influential at driving participation than financial incentives Biodiversity co-benefits of carbon planting is another important factor Many believe that biodiverse carbon […]

Sustainable development in the Daly Catchment

Getting the balance right Key messages: For economic development to be sustainable it needs to respect the different values people have for the region We developed a conservation plan for the Daly Catchment using a novel scenario-planning approach coupled with optimal land-use design We found that scenarios involving 10% clearing are most aligned with stakeholder […]
