In many places where martens live, trees are harvested for wood products, leaving martens with an environment very different from the forested one they prefer. When tree harvesting occurs, the marten’s habitat is broken up, large patches of open land are created, and the forest environment remains only in little patches or fragments. The scientists in this study, wanted to know if marten populations are shrinking because of forest fragmentation.
