Ahead of the global meeting of the Conference of the Parties in Montréal, Canada, which decides new targets for nature, the first-ever study of its kind outlines an urgent need for larger numbers and better-supported protected area staff to ensure the health of life on Earth. In a new scientific paper published today in the journal “Nature Sustainability”, an international team of scientists – including two members of the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Berlin – argue that there are not enough rangers and other staff to manage even the current protected areas around the world.
