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.
Higher street tree density was associated with a lower prevalence of childhood asthma even after adjustment for potential confounders (including sociodemographic characteristics, population density and proximity to pollution sources.
Learn about the five strategies to reduce the heat island effect: trees and vegetation, green roofs, cool roofs, cool pavements, and smart growth. Find out what state and local entities across the country are doing to reduce the urban heat island effect. Learn about how climate change and heat islands interact to exacerbate impacts. Learn how you can reduce the urban heat island effect in your community.
This initiative strengthens urban tree stewardship efforts by: creating and enhancing partnerships to achieve mutual urban forest management goals; assisting the urban forestry community in its assessment of the vulnerability of trees to potential threats; developing information, training materials, and tools to promote best management practices for the stewardship of trees; engaging corporations, community members and youth in urban forest management activities such as tree-planting, stewardship, and tree health monitoring; and conducting outreach to diverse audiences to raise public awareness about the importance of trees
This report develops a range of green infrastructure scenarios consistent with the constraints of a recently remediated brownfield that can be implemented within the framework of a 15- to 20-year development master plan. There are collections and descriptions of key findings during the exploration of this topic that can be applied to the Zidell site and other redevelopment projects of similar character. The conceptual design scenarios apply green infrastructure solutions that capitalize on infiltration and innovation for the remediated brownfield site with the goal of exceeding existing regulatory requirements for stormwater management and providing creative solutions with multiple community benefits.
