A global analysis of the impacts of urbanisation on bird and plant diversity

A newly published global analysis explores the impacts of urbanisation on birds (54 cities) and plants (110 cities). The density of species has declined substantially compared with non-urban estimates, but cities still retain endemic native species providing opportunities for regional and global biodiversity conservation, restoration and education. As urbanisation continues to expand, efforts directed towards the conservation of intact vegetation within urban landscapes could support higher concentrations of both bird and plant species.
