Areas of derelict infrastructure, e.g. railway lines, that are transformed into linear parks play an important role in urban green infrastructure networks and help to re-nature cities. Also regeneration along waterways and rivers often results in linear interconnecting parks.

Role of Nature / Mode of Action: 
Transition areas between biomes are called ecotones, green corridors with their linear natural elements can be seen as ecotones that connect neighbouring areas as well as distant areas. Ecotones are often rich in biodiversity because they are connected to two (or more) different biotopes.
Technical & Design Parameters: 
When green corridors are based on derelict infrastructure the location and the network properties are more or less fixed. For new developments green corridors can be designed as connecting elements.
Conditions for Implementation: 
Abandoned traffic infrastructure may be the most convenient way to establish linear parks and green corridors. The lack of care and sustained neglect of the area leads to an automatic development of the natural features in the space. For new urban developments linear elements can also be designed and build.
Benefits & Limitations: 
Benefits: Linear elements are very important for GI connectivity, the re-use of old grey infrastructure opens up a great potential for creating an interconnected system. Potential limitations/disservices: Depending on the previous use the green corridor may need a high level of maintenance (e.g. bridges).
