Fragmentation of the world’s forests has become so severe that 70 percent of remaining woodlands are now within 1 kilometer of a road or other form of development, according to a new study. Using the world’s first high-resolution satellite map of tree cover, as well as an analysis of seven long-term fragmentation studies, researchers showed that the ongoing destruction of global forests is decreasing biodiversity by as much as 75 percent in some areas and adversely affecting the ability of forests to store carbon and produce clean water. The study, published in the journal Science Advances, found that 20 percent of the world’s forests are just 100 meters from a human-created “edge.” Even many parks and protected areas have undergone fragmentation, the study said. The few remaining large, virgin tracts of forest are found in parts of the Amazon, Siberia, Congo, and Papua New Guinea.
