Residential green zones as additional habitats for mammals in a mountainous area around Beijing, China

ABSTRACT

Habitat loss and land use changes resulting from urbanization in residential communities are among the greatest threats to wild mammals. Identifying anthropogenic factors determining mammal diversity and composition can help coordinate socio-economic development with ecological conservation. In this study, we used transect surveys to compare the mammal assemblages near human-disturbed communities with those in the natural off-community area around Beijing, a major metropolis. We assessed the variables affecting the mammals’ presence using 19 environmental indicators. Of the twelve mammal species detected in the area, three vulnerable species have obtained legislative protection. In 58% of the observations, mammals were discovered around communities closer to croplands and located at slightly higher elevations with less vegetation, and these are the main environmental variables contributing to more mammals’ presences in the disturbed near-community area. The selection of croplands for the mammals in the suburb should be a trade-off between feeding benefits and predation risks, and with the rise of protection willingness, green zones near residential communities can serve as additional habitats for mammals facing the expansion of urbanization.
