The SRS Corridor Project

The most popular conservation technique to mitigate the effects of habitat fragmentation is the restoration of landscape connectivity with corridors. Yet, if and how corridors (and landscape connectivity, generally) influence biodiversity has remained unclear due to a lack of long-term, controlled experimental tests. We work within one of the world’s largest habitat fragmentation experiments – and the largest and best replicated experimental test of corridors – to understand the long-term effects of corridor connectivity for the longleaf pine ecosystem. Using a combination of demographic monitoring, plant community surveys, and plant-animal interaction experiments, we seek a mechanistic understanding of the long-term impacts fragmentation and corridors have on plant communities and populations.
