This assessment focuses on the environmental and socioeconomic impacts from the urban tree canopy (UTC) within the Urban Development Boundary of Miami-Dade County, as defined by the Miami-Dade County MPO (Figure 1). The area (intracoastal water areas excluded) encompasses approximately 1150 km 2 (444 mi 2). A combination of remote sensing and publicly available vector data was used to classify the following land cover classes: tree canopy/shrubs, grass, bare ground, wetland, water, building, street/railroad, other impervious surfaces, and cropland.
