Protected areas are hugely important for conservation.

Over the last 20 years, there's been a massive growth in a number of protected areas,

both in the marine realm and the terrestrial realm.

James Watson, with the Wildlife Conservation Society's Global Conservation Program and the University

of Queensland in Australia.

But what we're noticing is that these protected areas aren't well placed.

They don't really stop biodiversity loss in many places because they're not where important

areas of biodiversity is.

We also notice that protected areas aren't well managed and therefore often protected areas

don't actually lead to any significant conservation outcome. To address these issues, Watson and

colleagues published a blueprint describing how the scientific community can actually really help

national governments and protected area managers place protected areas that really

prioritise important biodiversity areas and achieve ecological representation. Their report is in the

journal Conservation Biology. Protected areas aren't the only tool in the toolbox and we've got to

make sure that other efforts actually work together holistically with protected

areas. So scientists can help identify metrics that help allow us to assess this. In these three
