More than two-fifths of the protected land in a global biodiversity hotspot in southwest China is under intense human pressure

Habitat loss is the main threat to global biodiversity in the Anthropocene. To prevent this, protected areas are the most effective means for safeguarding biodiversity. However, extensive habitat protection under human pressure can undermine its effectiveness. Using the Hengduan Mountains, a global biodiversity hotspot in southwest China as an indicator, we assessed the extent and intensity of human pressure to highlight how these pressures have changed over time. We found that most ecoregions had high levels of intact habitat loss relative to areal protection by national nature reserves (NNRs). More than two-fifths of protected land is under intense human pressure, and lower elevation or smaller NNRs were subject to higher pressure. These increases have predominantly occurred in lower elevation NNRs, showing that elevation gradients correlate with increasing pressure. While protected areas are increasingly established, they are experiencing intense human pressure. Our findings provide useful insights for assessing resilience of protected areas and to prioritize areas where future conservation plans and actions should be focused in a changing world.
