Report on the effectiveness of Wildlife Corridors

The idea of a wildlife corridor to aid conservation (or at least slow extinctions)  is not new, but how effective are they?   The New York Times recently carried a report on a new paper [*] in the Proceedings of the National Academy of Sciences, in which scientists have tried to quantify how a wildlife corridor strategy might be used to slow extinction rates in two biodiversity hot spots, the Atlantic Forest of Brazil and the Eastern Arc Mountains of Tanzania.

Clinton Jenkins, an ecologist at the Institute for Ecological Research in Brazil and a co-author of the study, said:

“We’ve known for a while that fragmentation elevates extinction rates and that these corridors can help, but we wanted to take that data and figure out what we’d actually gain by putting these forests back together.”

The Times has more detail on this story.


* Targeted habitat restoration can reduce extinction rates in fragmented forests.
