Want to preserve biodiversity? Go big, U-M researchers say

2025-03-12
ANN ARBOR—Large, undisturbed forests are better for harboring biodiversity than fragmented landscapes, according to University of Michigan research.  Ecologists agree that habitat loss and the fragmentation of forests reduces biodiversity in the remaining fragments. But ecologists don't agree whether it's better to focus on preserving many smaller, fragmented tracts of land or larger, continuous landscapes. The study, published in Nature and led by U-M ecologist Thiago Gonçalves-Souza, comes to a conclusion on the decades-long debate. "Fragmentation is bad," said study author Nate Sanders, U-M professor of ecology and evolutionary biology. ...
