Urban forests provide provisioning, regulating, cultural, and supporting ecosystem services. ES provided by urban forests are moderated by canopy cover and tree structure. ES are dependent on the intrinsic and temporal characteristics of different species. Not all species guarantee improved ecosystem function - some have disservices or undesirable outcomes. Non-native species numbers increase in cities and non-native species may reduce ES. Average 20% of trees in an urban forest were of the same species - low diversity overall even though there is high potential for diversity. Role of tree species diversity in ES provision is poorly understood.
