Urban Tree Canopy assessment and goal setting: Case study from Baltimore
Co-Authors: J. Morgan Grove and Jarlath P.M. O'Neil-Dunne
Abstract: In December 03, the Chesapeake Bay Executive Council signed Directive 03-01. Among other things, this expanded the riparian buffer directive "...recognizes that urban tree canopy cover offers stormwater control and water quality benefits for municipalities in the Chesapeake Bay watershed and can extend many riparian forest buffer functions to urban settings." And commits to, among others, the following goals: 1) By 2010, work with atleast 5 local jurisdictions and communities in each state to complete an assessment of urban forests, adopt a local goal to increase urban tree canopy cover and encourage measures to attain the established goals in order to enhance and extend forest buffer functions in urban areas; and, 2) Encourage increases in the amount of tree canopy in all urban and suburban areas by promoting the adoption of tree canopy goals as a tool for communities in watershed planning. Baltimore City became the first community in the Bay watershed to assess existing UTC (20%) and adopt a goal for UTC enhancement (40% in 30 years). The assessment and goal were enabled by combining remote sensing data and GIS data to quantify existing and potential UTC at the parcel level.
