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.

Raleigh, NC (July 23, 2014) — New research from North Carolina State University shows that urban “heat islands” are slowly killing red maples in the southeastern United States. One factor is that researchers have found warmer temperatures increase the number of young produced by the gloomy scale insect–a significant tree pest–by 300 percent, which in turn leads to 200 times more adult gloomy scales on urban trees.

Berkeley, CA (March 2, 2014) — From green roofs in Chicago to the High Line in Manhattan, U.S. cities have been making high-profile investments in green space. But could there be a downside to urban greening? A growing body of academic literature examines a paradox: Low-income communities tend to suffer from various kinds of environmental injustice, including shortage of green space. But when these concerns are addressed–the power plant closes, a park opens–the neighborhood becomes more desirable, often kickstarting a process of “environmental gentrification.”

France (July 1, 2014) — New research from France finds strangers are more helpful if they’ve just strolled through a natural environment. Research has consistently found exposure to a natural environment to be associated with health and psychological well-being. However, the effect of such an environment on social behavior and relationships remains in question.

July 9, 2014 — Recent research published in the journal Nature, looks at the affect of background climate on urban heat islands (UHI). The UHI, a common phenomenon in which surface temperatures are higher in urban areas than in surrounding rural areas, represents one of the most significant human-induced changes to Earth’s surface climate.
Dallas, TX (July 21, 2014) — The cities where we live are heating up, but trees and green infrastructure can help them stay cool. In late May, the Texas Trees Foundation hosted a regional conference, Grey to Green: Creating “Cool” Cities. They’ve just released a wrap-up report from the symposium which featured keynote speaker Dr. Brian Stone, an expert on urban environmental planning at the Georgia Tech.
Arlington, VA, and Knoxville, TN (May 23, 2014) — A new report released by the University of Tennessee Institute of Agriculture and The Nature Conservancy compiles the latest data and analyses on the introduction, spread, and costs of non-native invasive tree pests and diseases. Fading Forests III is the third study on invasive forest pests produced by the authors over a 20-year period.

College Station, TX (June 30, 2014) — A new life cycle assessment shows positive economic, environmental benefits of trees in landscapes. Why is it important to understand a tree’s carbon footprint? The authors of a new study say this vital information can help consumers appreciate the true benefits of planting trees in landscapes, and can also help differentiate horticultural products in the marketplace.

Madison, WI (April 11, 2014)- If you start feeling better as spring begins pushing up its tender shoots, you might be living proof of a trend discovered in data from the Survey of the Health of Wisconsin: The more green space in the neighborhood, the happier people reported feeling.

Gent, Belgium (August 2014) — Research discusses how a non-deep tree belt along a road can be an interesting solution to achieve road traffic noise reduction.
