I’ve mentioned before that John is active on the Arlington Tree Committee. He’s been behind a major push to inventory the town’s trees, aided by local government support and the legwork of many residents.

Other members of the committee have been using Facebook to link to interesting research on the value of trees to communities.

Science Daily, for example, reported on a study by Adam Dale et al. of the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) suggesting the best ways to keep trees healthy and sustain their economic value.

“Heat from city sidewalks, streets, and parking lots, along with insect pests, can damage trees planted in urban landscapes. Thus, it is critical to plant trees in the right places so they will do well in harsh urban environments, a University of Florida Institute of Food and Agricultural Sciences researcher says.

“More than half the world’s people and 80 percent of the U.S. population live in urban areas. Trees benefit these residents by filtering the air, reducing temperatures and beautifying landscapes. According to a new study led by Adam Dale, a UF/IFAS assistant professor of entomology, these benefits are reduced when trees are planted in unsuitable urban landscapes. However, guidelines can be developed to lead urban tree- planting decisions in a more sustainable direction.” Check out the researchers’ “Pace to Plant” technique here.

At the Toronto Star,

“Using data from Toronto, a team of researchers has found that having 10 more trees on your block has self-reported health benefits akin to a $10,000 salary raise or moving to a neighbourhood with a $10,000 higher median income or being seven years younger.

“By comparing satellite imagery of Toronto, an inventory of trees on public land and general health surveys, the team, led by University of Chicago psychologist Marc Berman, found that people who live on a tree-lined block are less likely to report conditions such as high blood pressure, obesity, heart disease or diabetes.

‘Their findings appeared [in 2015] in the open-access journal Scientific Reports.” More at the Star here.

And I’d be remiss if I didn’t mention that research social scientist Kathleen L. Wolf has written extensively on the value of trees: for example, in this Communities & Banking article on how “the urban forest” benefits local businesses.

Numerous studies show trees improve health and quality of life in communities and make shopping at local businesses more appealing.

John (founder of www.mistersmartyplants.com) is a member of Arlington Tree Committee. He figured out a way to use Google Maps to identify heritage trees in town and got a sign made to encourage residents to adopt a thirsty tree.

Now that so many urban and suburban areas have taken down their trees to make construction projects easier, people are realizing what they’re missing.

Many have noted that trees play a role in residents’ mental and physical health.

University of Washington research social scientist Kathy Wolf has studied the health aspects and also has economic arguments. She has shown that an “urban canopy”  makes local shopping more agreeable for customers and lends vitality to downtown business districts. Read what she has learned, here.

Chris Mooney at the Washington Post notes other research. “In a new paper published Thursday, a team of researchers present a compelling case for why urban neighborhoods filled with trees are better for your physical health. The research appeared in the open access journal Scientific Reports.

“The large study builds on a body of prior research showing the cognitive and psychological benefits of nature scenery — but also goes farther in actually beginning to quantify just how much an addition of trees in a neighborhood enhances health outcomes. The researchers, led by psychologist Omid Kardan of the University of Chicago, were able to do so because they were working with a vast dataset of public, urban trees kept by the city of Toronto — some 530,000 of them, categorized by species, location, and tree diameter — supplemented by satellite measurements of non-public green space (for instance, trees in a person’s back yard). …

“Controlling for income, age and education, we found a significant independent effect of trees on the street on health,” said Marc Berman, a co-author of the study and also a psychologist at the University of Chicago. “It seemed like the effect was strongest for the public [trees]. Not to say the other trees don’t have an impact, but we found stronger effects for the trees on the street.”

Thank you to my high school classmate, Susie from Cleveland, for putting the Washington Post article on Facebook.
