Baltimore would likely be a healthier city if it had more trees, and there’s plenty of research to support that claim. In addition to their role in human wellness, trees suck up storm water and provide awesome curb appeal to homes in city neighborhoods. Jill Jonnes, an accomplished author, is a champion of urban trees and the founder of the Baltimore Tree Trust, established in 2009 to promote tree plantings in the city, particularly in neighborhoods that have not seen healthy trees in years. Her latest book is “Urban Forests: A Natural History of Trees and People in the American Cityscape,” published by Viking.Links:http://jilljonnes.com/bio/http://baltimoretreetrust.org/our-mission-and-historyhttp://jilljonnes.com/
