Once considered the antithesis of a verdant ecosystem, cities are being hailed as efficient social ecological systems. Emerging from the streets of the post-industrial city are well-tended community gardens, reforestation areas, and other viable habitats capable of supporting native flora and fauna. At the forefront of this transformation are the residents themselves. Research by a Forest Service scientist at the agency’s Norther Research Station and her collaborators resulted in “Urban Environmental Stewardship and Civic Engagement: How planting trees strengthens the roots of democracy,” a book that discusses how people engage in stewardship and what civic participation in the environment means for democracy. The rResearchers interviewed MillionTreesNYC volunteers and found that that the simple act of planting a tree at a volunteer event was so transformative for first-time tree planters that it led them to become more civically involved in their community. As governments are investing in green infrastructure campaigns to change the urban landscape, this book sheds light on the social importance of these initiatives and shows how individuals’ efforts to reshape their cities serve to strengthen democracy.
