- Urbanization contributes to the loss of the world's biodiversity and the homogenization of its biota. However, comparative studies of urban biodiversity leading to robust generalities of the status and drivers of biodiversity in cities at the global scale are lacking. Here, we compiled the largest global dataset to date of two diverse taxa in cities: birds (54 cities) and plants (110 cities). We found that the majority of urban bird and plant species are native in the world's cities. Few plants and birds are cosmopolitan, the most common being Columba livia and Poa annua. The density of bird and plant species (the number of species per km2) has declined substantially: only 8% of native bird and 25% of native plant species are currently present compared with estimates of non-urban density of species. The current density of species in cities and the loss in density of species was best explained by anthropogenic features (landcover, city age) rather than by non-anthropogenic factors (geography, climate, topography). As urbanization continues to expand, efforts directed towards the conservation of intact vegetation within urban landscapes could support higher concentrations of both bird and plant species. Despite declines in the density of species, cities still retain endemic native species, thus providing opportunities for regional and global biodiversity conservation, restoration and education.

- Land use and land cover largely determine the ecosystem functions that can occur, where they occur, and the organisms that enable those. The composition and configuration patterns of land use and land cover will impact urban biodiversity; therefore how we recognize and understand those patterns is relevant towards planning to enhance biodiversity in urban ecosystems. This chapter addresses the past, present, and future of land use and land cover in urban areas by covering three main sections: The history of land use/land cover in urban areas, how biodiversity connects to land use/land cover under a landscape ecology framework, and how planning for sustainability and fulfilment of sustainable development goals can be done by addressing urban biodiversity at a landscape scale. Through concepts, examples, and tools, we expect readers to become immersed in the importance of land use/land cover configuration and composition for urban biodiversity and related ecological processes.
