Corridors in Conservation

Hundreds of corridors and connectivity projects are currently in use or being implemented around the world. They range from small-scale experiments or crossings to large, multinational habitat linkages.  They may be utilized by any living organism, regardless of size or mobility.

Man-made Linkages

Linkages created by humans are often associated with roads, railroads, or other linear infrastructure, which is a major source of habitat fragmentation.  These linkages act to mitigate the loss of connectivity by providing connectivity between remaining patches.

Wildlife overpasses or underpasses are key examples of human-created linkages. Other connectivity projects through urban areas such as greenways or riparian buffers may also act as man-made linkages.

Large-scale Networks

Large-scale networks connect habitats on a regional or international scale. They typically connect large blocks of wildlands or other protected areas, and may be preserved through conservation agendas or as part of large-scale restoration.

Corridor Experiments

Corridor experiments are used to evaluate corridor effectiveness. Many experiments are the size of grassland or forest plots, on the scale of meters to hundreds of meters, although there are examples of corridor examples at every scale.

Natural Corridors

Natural corridors typically follow geographic features, like mountain ranges or rivers.  These act as natural routes for dispersal or migration, but are often threatened by human encroachment or habitat fragmentation.
