Benefits
As well as noise control, traffic control, and glare and reflection control.

Urban wildlife
Urban forestry provides potential habitat for urban wildlife. In addition, it creates great opportunities for observing wildlife to the general public.

Social impact
Urban forest related events such as planting festivals can significantly reduce social isolation problems, enhance people's experience and raise environmental awareness.

Nanjing
Nanjing Vertical Forest Project designed by Stefano Boeri Architetti is currently under construction. 600 tall trees, 200 medium-sized trees and 2,500 cascading plants and shrubs will be planted on the building facades. It is expected to absorb 18 tonnes of CO2 while providing 16,5 tonnes of Oxygen annually.

Shanghai
A 99 km long and 100 m wide forest belt surrounding the city was completed in 2003. The heat island issue has been significantly reduced.

Another pilot project by Shanghai Municipal Agricultural Commission aims to convert 35% of the total area of Shanghai to urban forest. A forest network of two rings, eight lines, five zones, multi-corridors, multi-grids, and one chain was introduced in the project, which means planting two ring-shaped forests, an inner ring 500 m wide by 97 km in length surrounding the central district, and an outer ring 180 km long in suburban land, eight longitudinal forest belts 1000 m wide along expressways and major rivers, five large forest parks about 30 km2 each in area scattered in the suburbs, multiple green corridors 25 to 500 m, grids of forests along the seashore and in industrial areas, and one chain linking various habitats.

Preferred tree species
Native species usually provide more multilayered green space. Field surveys are recommended in order to make better use of these species. Monocultured forests should be avoided since they are susceptible to diseases and lacking biodiversity.
