Cities around the world are pursuing tree planting, motivated by the broad range of documented ecological, economic, and social benefits urban forests deliver. While large-scale urban tree planting campaigns have historically been undertaken in cities of the Global North, they are emerging in other cities, including Kenya’s capital, Nairobi, the location of this proposed research. Despite ambitious tree planting goals, there has not been a comprehensive effort to survey the current state of Nairobi’s urban forests. I will study Nairobi’s urban forest with a focus on the ecological structure of street tree communities. Specifically, the study asks whether the abundance, size class, diversity, and composition of street tree communities differs across three neighborhoods of varying incomes levels in Nairobi. This observational study aims to address a knowledge gap on Nairobi’s street trees, and in doing so, inform tree planting campaigns in favor of an equitable distribution of tree canopy and associated benefits.
