Pollinator biodiversity and abundance is an ecosystem service vital for humans, provisioning a range of essential goods including food, fibre and medicines. Despite this, pollinators are under threat and are experiencing global declines. Habitat loss is a driving force behind such declines and, as such, the potential to provision more pollinator habitat is of interest. Currently, urban areas host abundant unused space in the forms of roofs and walls, which could be utilized to provision some pollinators with additional forage, and possibly nesting sites, without compromising human use of the land. While several studies exist regarding the habitat potential of living roofs, the impact of living walls on biodiversity is little studied. This paper sets out a theoretical approach on whether living walls could be used to host pollinator habitat by surveying living wall manufacturers regarding the physical properties of the living wall systems they use and their plant choice.
