A new study led by the British Trust for Ornithology (BTO) examines the benefit of well-managed protected areas for declining bird populations.

Nature is declining faster than at any time in human history, with an estimated one million species across the globe currently threatened with extinction due to human activities. In December 2022, a landmark agreement called the Kunming-Montreal Global Biodiversity Framework was established by world leaders from 196 nations, to halt nature loss and prevent ecosystem collapse. One of the Framework’s key targets, known as ‘30 by 30’, was to protect 30% of the world’s land, coastal waters, and oceans by 2030. This has led to a rapid expansion in land being designated as specially protected in recent years.
