Sammendrag

Increasing urbanisation results in changes to the landscape and causes fragmentation of habitats as well as habitat loss. As a result of the global decline of pollinators, there is increased interest in attempting to improve the habitat and environment for pollinator species and the fundamental ecological services that they provide. Literature on pollinator species in urban environments was examined and a number of general recommendations for the implementation of a pollinator stepping-stone corridor linking Sognsvann and Nøkkelvann resulted from the literature review.

The literature review utilised Web of Science and Google Scholar to gather information focusing on pollinator species in the urban landscape. It was found that the urban environment is a fragmented landscape consisting of a mosaic of patches that contain numerous features, such as forage and nesting sites, which various pollinator species may utilise. Additionally the urban environment was found to have a high pollinator species diversity. The finding that the urban matrix is not inhospitable to pollinator species suggests that a pollinator stepping-stone corridor may assist in improving connectivity between green patches in the urban environment as well as the natural forest habitat surrounding Oslo. Additional research would be required to determine the usage of such a stepping-stone corridor by pollinators and adjust its design accordingly.
