Evaluating Air Quality Effects of Urban Trees - NUCFAC Application
An example application submitted to NUCFAC for the 1995 grant process.
A previous NUCFAC cost-share project has determined that there is a significant potential for developing credits within State Implementation Plans, based on ozone reduction due to urban forests,which can be used to fund future long-term urban forest management. Before these credits can be developed, the U.S. Environmental Protection Agency (EPA) needs evidence that the approach isdirectionally sound. This project proposes to produce evidence that will aid in the development of directionally sound programs for state ozone attainment goals, thereby facilitating the development of these credits. In addition, this project will quantify the effects of urban trees on numerous other air pollutants. Results of this project will have nationwide impacts, potentially affecting urban forest funding in many urban areas that have poor air quality.
Detailed analysis of urban forest cover, structure (i.e., species composition, tree size and condition) and air quality effects will be conducted for seven cities: Baltimore, MD; Baton Rouge, LA;Boston, MA; New York City, NY; Jersey City, NJ; Philadelphia, PA; and Camden, NJ. Urban forest structural information is necessary to quantify the air quality effects and will also provide good management information for the cities. Air quality effects will focus on pollution removal and volatile organic emissions by trees. Carbon sequestration by trees will also be calculated. The main focus of the project will be on the overall effects of trees on ozone in cities. Current and next generation state-of-the-science photochemical models will be used to quantitatively evaluate this overall effect. Model results will aid in developing directionally sound ozone programs, thereby creating cost-effective ozone control strategies using urban vegetation.
