Corridors in Conservation
Hundreds of corridors are currently in use in the United States and around the world. They range from small experimental plots to large, multinational habitat links. Here are a few examples of how corridors are being implemented in conservation:
Corridors created by humans are typically associated with roads, that are major sources of habitat fragmentation. Wildlife overpasses or underpasses are key examples of human-created corridors. Other corridors through urban areas such as greenways or riparian buffers may also constitute man-made corridors.
Large-scale corridors connect habitats regionally to internationally. These typically connect large blocks of wildlands or other protected areas. These corridors are either preserved through conservation or are part of active restoration.
Experimental corridors are used to evaluate corridor effectiveness. Most experimental corridors are the size of grassland or forest plots, on the scale of meters to hundreds of meters. Some experimental corridors are even smaller, and my consist of patches of mosses or wetlands contained in vials.
Natural corridors typically follow geographic features, like mountain ranges or rivers.
