Decision science & conservation at Zealandia Dr Danielle Shanahan is Manager of Conservation & Research at Zealandia, a 225 ha wildlife sanctuary that lies in the centre of New Zealand’s capital city of Wellington. It’s not a zoo or a museum but a world-first experiment on how to combine effective restoration and threatened species management […]

Guidelines need to look beyond species traits for good outcomes Key messages: Fire-management guidelines are often based on the traits of individual species We studied the association between the recent fire regime and the plant community in three common vegetation types of coastal SE Australia Guidelines considering different vegetation types as separate management units may […]
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 […]
Richard Hobbs, Leonie Valentine and colleagues believe we should be paying increased attention to species movement in response to environmental change (Hobbs et al, 2017). In particular we need to consider changes in species distributions and altered biological assemblages. Such changes are well known from paleoecological studies, but have accelerated with ongoing pervasive human influence. […]
Fire regimes and environmental gradients shape the distribution of forest wildlife KEY MESSAGES: Important insights can be gained by modeling how fire regimes, not just fire events, influence biota in forests Management of fire regimes needs to be complemented by an understanding of the underlying environmental gradients and key elements of habitat structure that influence […]
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 […]
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.
