In the 1990s, many cities changed their sustainability policies. The shift was a response to an environmental crisis arising from urban mitigation, technological change, economic liberalism and global warming (Haase, D et al., 2017,64). Since the 1990s, policy agendas for the built environment have advocated for denser, more compact developments with a mix of uses. Biodiversity narratives range from an emphasis on vertical and horizontal artificial surfaces that can provide a range of habitats to narratives based on habitat loss and extinct and endangered species. While the circumstances of urban density are well-documented, the biological approach to greening is somewhat ideological and encompasses a much broader set of goals and outcomes, which means it is often difficult to evaluate or establish targets (Mackenzie, A, 2020). Narratives of loss often raise questions about the biodiversity that urban spaces can provide and about how narratives inform design. During the design stage, narratives about biodiversity provoke or inspire the planners and designers. Later on, the narratives arouse the interest of local people and make them care enough to make changes, or simply make them comprehend and act appropriately when ecologists predict a new mass extinction (Meyer, A, 2009, 6; Rosenzweig, S, 2003, 194).
