Tree Research

To help local tree advocates make the case for trees in their communities, ACTrees has compiled Benefits of Trees and Urban Forests: A Research List.  This research listing includes over 150 tree benefits and facts, ranging from the national to the hyper-local level, and all with complete scientific citations. This information tells the story of trees in dollars and cents, in pounds and percents, with compelling data about why maintaining and growing a healthy urban forest is a smart, sustainable investment.
