Orangutans (and science) in trouble

Will the orangutan be saved? KEY MESSAGES: For many threatened species the rate and drivers of population decline are difficult to assess accurately We applied novel methods for integrating field and interview survey data for the Critically Endangered Bornean orangutan Our analysis revealed that Bornean orangutan populations have declined at a rate of 25% over […]

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 […]

Should we protect highly threatened habitats or safe habitats?

Risk it or play it safe? KEY MESSAGES: There is a bias towards placing MPAs in areas that are least threatened We found that conservation targets in our study area could not be met solely by avoiding high threat areas A threat selection strategy should be part of the management toolbox Cost-effectiveness in spatial conservation […]

Tracking seabirds for conservation

Seabirds are arguably the most threatened group of birds on the planet and conservation scientists all around the planet are working to understand how we can better protect this group of animals. Many studies involve tracking the movements of these highly mobile birds using a suite of tracking technology (telemetry). CEED recently joined forces with […]

How often, how far, how risky and how biased?

Movement behaviour mediates the impacts of habitat fragmentation at multiple scales KEY MESSAGES Different scales of fragmentation have lethal consequences for animals with certain movement traits For at-risk species, the impact of fine-scale fragmentation was accentuated when fragmentation also occurred at the coarse scale The land use to target with conservation actions to reduce fragmentation […]

On target to save more species

Targets such as a species’ minimum viable population size or the optimum proportion of land that should be protected (Decision point #83) are important for translating the complexities of biodiversity conservation into clear, generalizable rules. However, setting the same high-aspirational target across different species and landscapes may not be very efficient. To begin with, it is unlikely that different species will respond in exactly the same way to the same conservation target. This could result in unequal levels of protection, and eventually lead to an overestimation in the amount of conservation actually achieved.
