Air temperature in North America is projected to increase by 1.5 °C by 2050 and this increase will be most pronounced in cities due to the urban heat island effect. In the urbanized northeast United States, midsized regional cities (pop. 35,000 - 250,000) have similar populations, when combined, to major cities such as Boston but have received little research attention. In addition, mid-sized cities do not have similar resources available which limit their capacity to respond to climate change. The urban forests in midsized cities are an important component of green infrastructure because they provide myriad environmental services to residents, including the reduction of the surface urban heat island effect through evapotranspiration and shading of impervious surfaces. To justify municipal investments in tree planting programs, the impact of urban forest canopy on land surface temperature in the heterogeneous urban landscape is an increasingly important area of study. Energy reduction savings during the peak hours of the day through the reduction of temperatures depends on the stewardship of public and private trees by multiple stakeholders, including residents, non-profits and businesses. Effective governance of urban forests relies on coordination across organizational scales from individual residents focused on caring for their property to city workers providing maintenance of public infrastructure. Increased understanding of the impact of stewardship regimes can be achieved through a mixed-methods approach using resident interviews with empirical tree health data to link stewardship regimes with tree survivorship. This research uses the Greening the Gateway Cities Program (GGCP) as a case study to examine how reconceptualizing the urban forest can lead to increased stewardship and improve the potential of urban forests for reducing urban heat island effect. The objectives of this dissertation are to analyze the GGCP through three different frames: (1) the spatial distribution of extreme heat in environmental justice communities during a heat wave in eastern Massachusetts; (2) residents' role in governance of the urban forest; and (3) the impact of resident stewardship regimes on the tree health of juvenile trees planted in the last five years. Chapter 2 examines the spatial distribution of extreme heat in Massachusetts using an environmental justice framework. Extreme heat is found in 85% of environmental justice neighborhoods but places where multiple environmental justice factors are present are significantly hotter. Neighborhoods can be categorized according to their socioeconomic, vegetation, and extreme heat characteristics to help the state work with local communities to implement tree planting and other cooling strategies. Chapter 3 uses resident, non-profit, and municipal interviews to understand the residents' role in governance of a tree planting program. Residents who are Active Participants are those that communicate and negotiate with the tree planting program. These residents are motivated by a variety of discourses, demonstrated consistent stewardship, and had very high tree survivorship. Tree planting programs should purposefully identify these Active Participants to increase the reach and success of the program. Chapter 4 examines residential trees in Chicopee, a Gateway City, to understand the important factors impacting tree survivorship. The analysis uses interviews to show how residents' aesthetic preferences significantly impact tree survivorship. This dissertation demonstrates that residential tree planting in dense urban neighborhoods is necessary and possible to mitigate impacts of the urban heat island and address longstanding environmental justice concerns.
