Why is biodiversity high in cities?

“Cities are often very rich in biodiversity, and that is because they were located in very rich areas, in floodplains and in low areas with high fertility,” says Elmqvist. “So naturally, you would have very high diversity of plants and animals. Now, cities need to learn how to co-exist with that biodiversity.”
