About Paper:

Urban green spaces are essential for maintaining biodiversity as they provide habitat for pollinators in city landscapes. However, these green spaces vary significantly in their level of urbanization. This study examines how different levels of urbanization affect the abundance and diversity of pollinators in Nanchong, a city in the Sichuan province of southwest China. Nanchong is a city of over two million people surrounded by a rich and diverse ecosystem, including hundreds of species of pollinators. We examined the differences of pollinator interaction between areas of high urbanization (urban parks) and relatively low urbanization (temple areas and farmlands). For this study, we placed six one-meter by one-meter quadrants over different flowering plants in each of our chosen study sites. We observed pollinator sightings and interactions with the plants over 10-minute periods, recording the types of plants and pollinators present. Our findings indicate similar levels of pollinator abundance, but a higher level of interaction and pollinator diversity in areas with less urbanization. Especially in China, where population density and urbanization are high, it is helpful to understand what types of urban green spaces are most conducive to pollinator interactions and biodiversity, therefore
