Exposure to Urban Nature and Tree Planting Are Related to Pro

Pro-environmental behaviors (PEBs) may be associated with a personal relationship with nature. We conducted a quasi-experiment with 423 residents who had or had not actively participated in a tree-planting scheme and lived in 20 neighborhoods that differ in their greenness level. We tested whether exposure to nature (specified by the amount of vegetation cover in residents’ neighborhoods) and/or past PEB (specified by tree-planting participation) was associated with residents’ PEB and whether key psychological constructs would mediate these relationships. Structural equation mediation models revealed that the level of neighborhood vegetation and involvement in the planting scheme explained 46% of the variance in PEB, with connection to nature, the use of nature for psychological restoration, and environmental attitudes mediating the relationships. Connection to nature was more strongly associated with engagement in PEB than the use of nature for psychological restoration and environmental attitudes
