Achieving the targets of global conventions

A special issue of Conservation Letters In December 2016, Conservation Letters released its first special issue with the theme of ‘Achieving the targets of global biodiversity conventions’. The issue was spearheaded by members of CEED and the Centre for Biodiversity and Conservation Science (CBCS), specifically Moreno Di Marco, James Watson, Oscar Venter, and Hugh Possingham […]

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 […]

Learning about past restoration effort

The case of the grey-crowned babbler KEY MESSAGES Understanding the value of restoration requires measuring change through time Measure response variables that are meaningful Counterfactuals are necessary: Compared to what? Many resources are spent on restoring habitat to counter the impacts of land clearing and habitat degradation on wildlife populations. But individual projects involving restoration […]

Which birds are ‘woodland birds’? It depends on who
you ask. These are black-faced woodswallows, classified as a woodland bird in 37.5% of lists. (Photo by Eric  Vanderuys)

What’s in a name?

The consequences of inconsistently classifying woodland birds (and other terms) Key messages woodland birds are inconsistently classified this inconsistency has a significant impact on research involving woodland birds inconsistencies in other areas of conservation science are likely having similar impact Woodland birds are bird species which depend on native woodlands. They are sometimes called woodland-dependent […]

Clearing of mulga in central Australia. Conservation activities in heavily cleared landscapes focus on keeping the remaining large patches intact, often disregarding the increasingly important role of smaller patches in conserving biodiversity. (Photo by Michelle Venter)

Small patches need greater protection

Small patches of native vegetation are critically important to biodiversity conservation and need greater protection from clearing according to a new analysis undertaken by Ayesha Tulloch and colleagues. Just because a patch of native vegetation might be small, doesn’t mean we can afford to lose it. The researchers examined historical and current patch-size distributions to […]

Sleepers in the grass

In many far flung paddocks on private land in south east NSW stand star posts marking the location of a collection of rail sleepers, sheets of corrugated tin and roof tiles. These are survey stations set up by Geoff Kay and David Lindenmayer from the ANU. These little islands of artificial habitat are magnets for […]

What’s the point?

How much native habitat is enough? The question for farm and landscape planning is: ‘How much intensive production can take place without excluding most native species from the landscape?’ Roughly speaking, if any land use that largely excludes native biodiversity (eg, crops, plantations, fertilised pastures) covers less than one-third of the landscape, it is unlikely […]
