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.

I was reading an article by Kathleen Wolf, a social scientist whose “work is based on principles of environmental psychology and focuses on the human dimensions of urban forests and ecosystems.”

The following words struck me: “Interviewees say that merely looking at trees tends to reduce mental and physical stress. A walkable green environment is also thought to increase life satisfaction in later life and even longevity.” Hmm.

So to borrow some words from local honcho H.D. Thoreau, “I went to the woods to see if I could live” longer.

Photos include the Hapgood Wright Town Forest, Joe Pye Weed, an Eastern Tiger Swallowtail, a log like a scaly snake, and various fungi indicating mysteries beneath the surface.
