A 2003 study by the Trust for Public Land reinforced that urban forestry and community gardens are good partners. Largely basing this assertion on a University of Illinois study, they concluded that trees help to foster an environment of reduced stress and a better aware community.
Gardens create community, by giving residents an active role in the neighborhood and a sense of control over an important aspect of their lives. Neighbors come together in gardens both to work the land and to socialize. A University of Illinois study concluded that inner-city residents living near common spaces with trees know one another and socialize more with neighbors, believe they can call on a neighbor for support, and feel safer than residents living in barren areas.
