Greening the Gateway Cities Program (GGCP) The goal of the GGCP is to increase tree canopy cover in Massachusetts’ Gateway Cities to increase energy efficiency in urban residential areas. Target Areas: Low tree canopy ● ● Old Housing Stock High Wind Speeds ● Large Renter Population ● ● Environmental Justice Neighborhoods 5
What is a “Gateway City”? Industrial urban centers ● Populations between 35,00 to 250,000 ● ● Median household income and educational attainment below state average Leominster Pittsfield Google 2017 Google 2018 6 Park Square, Pittsfield Center Monument Square, Leominster Center

Research Questions What are the biophysical factors and the social networks that influence tree health in the GGC program? How does tree health in 2019 compare to previous HERO results? Tree Survey: y: Inter ervi views: What is the survivorship of the trees How do actors communicate amongst each • • planted in Leominster and Pittsfield? other? How does tree health compare across • How is tree stewardship approached and • the two cities? implemented? By genus • What are the discourses associated with • By location • the program? By tree characteristics • 11
