A global assessment of the impact of individual protected areas on preventing forest loss.

Globally, the number and extent of terrestrial protected areas (PAs) are expanding rapidly. Nonetheless, their impacts on preventing forest loss and the factors influencing the impacts are not well understood, despite the critical roles of forests in biodiversity conservation, provision of ecosystem services, and achievement of the United Nations' Sustainable Development Goals. To address this important knowledge gap, we quantified the impacts of 54,792 PAs worldwide on preventing forest loss from 2000 to 2015, and assessed important landscape and management factors affecting the impacts of PAs.

Effectiveness of China's protected areas in reducing deforestation.

Protected areas (PAs) are considered a cornerstone of biodiversity conservation, and the number and extent of PAs are expanding rapidly worldwide. While designating more land as PAs is important, concerns about the degree to which existing PAs are effective in meeting conservation goals are growing. Unfortunately, conservation effectiveness of PAs and its underlying determinants are often unclear across large spatial scales.
