Restoring Urban Ecosystems with Trees: Cleaning and greening
February 11, 2015, 2015

Ronald S. Zalesny Jr., USDA Forest Service
Richard A. Hallett, USDA Forest Service

Trees can be used to clean contaminated soil and water and create forests in our urban areas. This helps meet the global need for technologies that simultaneously enhance ecological restoration and increase green space in our communities. In this webinar, we present examples of phytoremediation (using plants to clean soil and water) and afforestation (creating forests) projects designed to provide ecosystem services across a variety of urban sites, from brownfields to parks. Ron Zalesny will describe phytoremediation, a class of phytotechnologies that uses the natural filtering ability of trees to remove pollutants from liability lands while moving from ecosystem degradation to restoration. Rich Hallett will introduce the concept of anthropogenic succession to support the creation of forests in cities. The speakers will highlight the potential for using phytoremediation plant selection techniques to select species and varieties that are uniquely adapted to specific urban afforestation sites. Combining these concepts could lead to hyper-performing urban afforestation projects that will have reduced recurring maintenance costs coupled with the ability to take up harmful compounds in tree tissues.
