... One important elemment of "urban ecology" is the role of tre in providin a wide ees ng variety of environmenta benefits, suc as al ch  seque estering of carb bon, thus conntributing direc to climate change mitigation; ctly e  reduction of air pol llution through direct deposition of pollu utants and thro ough cooling effects that reduce the formation of ozone; s t  shadin of building which can lower energy demand for a conditioning; ng gs, y air  reduction of urban heat island (UUHI) effects;  interception of water runoff, thus buffering loc waterways from pollutio and helpin s cal s on ng ntrol stormwat overflow problems; to con ter p  provis sion of vital ha abitat for wild dlife; and  access to nature.

... :  current capabilities to characterize and quantify the benefits ("ecosystem services") provided by trees and forest canopy cover within a metropolitan area, which may include benefits to public health and well-being;  key gaps in our understanding and our ability to model, measure, and monitor such services, and improvements that may be needed to allow tree planting to be sanctioned as a "creditable" strategy in official regulatory control programs (i.e., for air quality, water quality, and climate change response)

... Thus there is growing interest in an important, multifaceted area for research that reaches across many disciplines of physical, biological, and social sciences. A major goal of this research is to be able to provide clear, compelling scientific guidance that can help cities grow and sustain forest canopy cover in a way that maximizes and sustains benefits and minimizes costs and potential unintended consequences (such as increased pollen load, risk of fire and storm damages, and greater requirements for water resources)

... The committee hopes that this report will provide a useful resource to the wide array of urban forestry stakeholders (e.g., researchers and program managers in agencies such as the USFS and the EPA, academic researchers, and foundations and non-governmental organizations that support community forestry issues) , in particular to help shape their support for future research.

... . Cultural ecosystem services: Nonmaterial benefits people obtain from ecosystems, such as cultural diversity, spiritual and religious values, knowledge systems, educational values, inspiration, aesthetic values, social relations, sense of place, cultural heritage values, recreation and ecotourism.
