Biodiversity and Green Roof Retrofit
Green roof retrofits have the potential to increase urban biodiversity by providing animal habitats. Many municipalities explicitly list ‘benefits to biodiversity’ as part of the rationale for building or retrofitting green roofs. But do green roofs increase animal biodiversity? Although green roofs can provide food sources for bats and birds, there is little evidence that green roofs increase bird or bat populations; in at least one case, green roofs appear to act as an ecological trap, attracting birds to build nests in habitats that cannot support their offspring. In contrast, green roofs support a wide variety of invertebrate species, but at levels that are usually below those of other urban green spaces such as parks or bushland fragments. Nevertheless, green roofs may play a role in urban conservation by creating corridors, connecting otherwise isolated populations. Future retrofits can increase invertebrate biodiversity by providing structurally complex habitats, providing a mixture of pollen and nectar‐producing plants and using diverse substrates.
