Conserve intact forest landscapes to maximize biodiversity, reduce extinction risk

“We have seen declines in species in landscapes that have already lost a massive amount of habitat,” said Matthew Betts, lead author and professor in the College of Forestry at Oregon State University. “But we found much more support for what we call the initial intrusion hypothesis. It’s the initial hit caused by roads going into tropical forests and the human activities that follow that is most substantial. These are also the spots with the greatest sheer numbers of species.”
