“Urban ecology research is changing how we view the biological value and ecological importance of cities,” write a group of international, multidisciplinary scientists in Conservation Biology. Cities can be wildlife refuges and can be managed to support biodiversity and ecology.
“In a rapidly urbanizing world, transforming how environmental managers view the city can improve citizen engagement while exploring more sustainable practices of urbanization,” writes Jeff Ollerton, University of Northampton, on his Biodiversity Blog.
Ten years of research on wild Urs in cities shows that cities can be pollinator biodiversity hot spots. The loss of habitat and homogenization of agricultural lands and increased use of a variety of pesticides everywhere has affected wild pollinators. In the past, conservationists and the public have excluded cities with the attitude that they must be devoid of wildlife.
Small actions can yield big results they write. How? Forage (flowers) on vacant lots and residential land. Decisions made by individuals on how to manage land matter. Work done so far shows that residential plantings in low-income, low-density city neighborhoods have greater bee diversity than higher-income neighborhoods. Likely that’s due to more vacant lots, abandoned buildings and less pesticide use.
