Corridors Increase Plant Species Richness at Large Scales, Science
 









Excerpts: Habitat fragmentation is one of the largest threats to biodiversity.
Landscape corridors, which are hypothesized to reduce the negative consequences
of fragmentation, have become common features of ecological management plans
worldwide. Despite their popularity, there is little evidence documenting the
effectiveness of corridors in preserving biodiversity at large scales. Using a
large-scale replicated experiment, we showed that habitat patches connected by
corridors retain more native plant species than do isolated patches, that this
difference increases over time, and that corridors do not promote invasion by
exotic species
