Study confirms PAs boost wildlife, but only if actively & effectively managed
Campaigns to protect the natural world are getting more and more ambitious. The popular “30x30” movement, for example, seeks to protect 30% of Earth’s surface by the year 2030. But although there is convincing evidence that protected areas such as national parks prevent habitat loss, proof that they actually benefit wildlife is surprisingly scanty. Now, the first large study of its kind shows nature reserves can increase waterbird populations, but typically only if humans take an active role in their management.
