The title of this ASLA blog post says it all…

“Everyday exposure to trees enhances your health now and promotes health across your entire lifespan,” said Dr. William Sullivan, Ph.D., a professor of landscape architecture at the University of Illinois, Urbana-Champaign, at a conference on the Washington, D.C. region’s urban tree canopy organized by Casey Trees. Some 150 urban forestry policymakers, experts, and designers heard Sullivan make the striking argument that the social and psychological benefits of trees and other greenery may even eclipse their ecological benefits. Research, based in real data, is now clearly demonstrating that exposure to trees brings people together, reduces crime, and lowers stress. Furthermore, trees are even a matter of life and death — their presence is a predictor of death rates for many.
Given that social ties are a predictor of our health and well-being, we need healthy, strong ties across our lifetimes. “Social ties are what glues us together. And people with stronger social ties have better health outcomes.” Sullivan outlined how social support buffers stress hormones, reduces blood pressure, increases chances of adopting healthy patterns, all of which lead to reduced mortality and morbidity rates and healthier lives.
In case the audience didn’t understand what he meant by social ties, Sullivan laid it all out. Social ties involves people getting together to see each other. There’s a progression in human relations. At first, there’s nodding, then smiling, then chatting. “Some people you chat with become friends.” Strong social ties involve those people we rely on. Weak social ties though are also hugely important. But social tie formation isn’t just dependent on how social you are, your environment also plays a large role. Sullivan pointed to a standard example of a sprawled out bedroom community and explained how these places reduce social tie formation, while green landscapes, streets improve these crucial ties.
