Urban Forest Landscape

Urban Forest Landscape Priority (FIGURE 1b-7) The Urban Forest Landscape Priority map complements the Maintaining Viable Urban Forests map (FIGURE 1b-5) by adding layers from these maps that have an urban component: Conserving Working Forestlands (FIGURE 1b-2), Protecting Forests and Communities from Wildfire Risk (FIGURE 1b-3), and Forest Health Priority (FIGURE 1b-4). Wildland-urban interface areas have inherent urban components, and many of these areas need intervention to reduce wildfire risk. Improving water quality is a commonly cited reason for maintaining urban tree canopy. Forest insects and diseases spread regardless of what is urban forest and what is rural; indeed, many invasive pests become established first in urban areas due to the easy movement afforded by dense transportation networks. Much of the forestland delineated as priority in this map are tracts of less than 14 acres. Parcelization and fragmentation are issues that must be addressed to effectively manage these forests.
