ABSTRACT
Urban green corridors form a key part of urban green infrastructure. In the 1980s the urban ecological work led by Sukopp in Berlin began to be put into practice in preparation of a future Species Protection Plan for the city. The term ‘corridor’ in the context of urban design and planning has been used in extremely diverse ways leading to multiple possible definitions of meaning. Radio frequency identification technology equipped transceivers have been used to describe the energetics, cognitive abilities, and presence/absence of hummingbirds at feeders in urban gardens. The DNA sampling has made a major contribution to establishing possible gene flow in urban areas. Streams and rivers do form potential wildlife corridors through urban areas, but the small first and second order stream routes, in particular, often become the site of rubbish dumping, both in the stream and on valley sides.
