Integrated studies of tree effects on air pollution reveal that management of urban tree canopy cover could be a viable strategy to improve air quality and help meet clean air standards. A modeling study using hourly meteorological and pollution concentration data from across the coterminous United States demonstrates that urban trees remove large amounts of air pollution that consequently improve urban air quality.
Among preschool children from low-income families, neighborhood homicide rate was associated with more obesity and street tree density was associated with less obesity.
A centerpiece of the i-Tree suite of tools, Landscape calculates the multiple benefits delivered by a community’s trees — from stormwater reduction, improved air quality, heat island abatement, student performance and public health. Users can overlay demographic indicators to determine where adding tree canopy can provide the most benefit to neighborhoods that need it most.
A searchable database of research projects published by the US Forest Service, many dealing with urban forestry. Other relevant issues touch on insects, disease and invasives.
EPA maintains a series of web guides to all aspects of green infrastructure, from planning to funding and long-term maintenance. Especially useful to determine where and how green infrastructure and urban forestry can meet federal and state rules for stormwater management. Includes many case studies, tools and calculators.
With a variety of data layers, and more added frequently, Community Commons offers non-GIS users the opportunity to create multi-level maps that can pinpoint areas of poverty, pollution and opportunities to redress environmental inequity. Also covers health, education, income, housing, food deserts and a host of other topics. Free and Easy to Use Mapping Tool.
This guide is intended to help engineers, planners, developers, architects, arborists, and public officials understand how trees perform and interact in a stormwater management system, and the new technologies that are being used to increase the stormwater utility function of the urban forest, even in the densest urban environments. The presence of trees in a streetscape, neighborhood, and community can decrease the amount of stormwater runoff and pollutants that reach local waters.
This document provides approaches that local government officials and municipal program managers in small to midsize communities can use to incorporate green infrastructure components into work they are doing in public spaces. The document presents examples and case studies of how integrating green infrastructure methods can enhance retrofits and maintenance projects and provide other multiple community benefits.
Existing trees save utilities about three-quarters of a billion dollars a year!
EnviroAtlas is a relatively new open-access geospatial tool. It combines a series of indicator data available for the contiguous United States that is to be updated as new foundational data is released. Indicator data are organized into seven categories which include clean air, climate, clean water and biodiversity. EnviroAtlas also includes reference data on demographics, land cover, political boundaries, watershed boundaries, NPDES permit status, and impaired and listed waters.
