**Protected nature reserves alone are insufficient for reversing biodiversity loss, researchers say**

Biodiversity is dwindling at a rapid pace across the globe. As one key remedy, we are protecting areas around the world, hoping that they will suffice to save what is left. While protected areas have undoubtedly contributed to slowing the overall biodiversity loss, it is unclear how well they work across multiple species concurrently. To explore this, researchers at the University of Helsinki examined changes in the occurrence of hundreds of species within and outside of protected areas.
