 Global forest fragmentation has been increasing since 2000 with the tropics experiencing the highest levels of fragmentation. However, there have been some improvements in the more temperate and subtropical regions, such as northern Eurasia and south China. The study identified eight distinct types of forest fragmentation, which can be used to assess the health of individual forests. This information will help inform policymakers about how best to protect and restore forests. This article was authored by Zhen Ma, Zhou Wei Li, Wen Ben Wu, and others.
