Two New Tools for Planning a Healthy Urban Canopy

Trees are a vital part of urban communities, providing social, environmental and economic benefits. However, the urban environment is a difficult one for most trees. The U.S. Forest Service has developed two new tools to help plan for and manage a healthy urban forest: one that guides designers and tree managers to select tree species likely to survive in the built environment, and another to monitor tree health to ensure trees become an asset instead of a liability.

When It Comes to Walkability, Mexico City Is Miles Ahead

Mexico City is a city of wide sidewalks and integrated bike lanes, lush parks and cool street tree canopies, and dense, mixed-use urban neighborhoods. As a matter of fact, nearly every neighborhood within Mexico City’s giant ring road—the Circuito Interior—has a walkscore above 95. Many major U.S. cities lack even one neighborhood with such a high score. Even on the outer fringe of Mexico’s sprawling Distrito Federal, neighborhoods often have walkscores upwards of 70, qualifying as “very walkable.” What makes... Read more

Research Shows Trees in Bioswales Provide Significant Stormwater Benefits

When we talk about the value of urban trees and soils as a stormwater management tool, the contribution of the trees is often considered secondary. Soil will, of course, store significant amounts of runoff all on its own. However, new research at the Morton Arboretum in Lisle, IL, has found that trees actually provided the largest proportion of their bioswales’ stormwater benefits, and trees also provide many other benefits soil alone does not.

In the City of Trees, a new ordinance will put more bite in tree protection. The Sacramento City Council gave unanimous approval to an ordinance that will better protect Sacramento’s existing trees and foster expansion of the urban forest. The ordinance provides new rules for safeguarding, maintaining and removing trees on both private and public land. Read more... Read more

Scientists Have Discovered that Living Near Trees is Good for Your Health

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 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.

Climate Adaptation: What Trees Are Suitable For Urban Heat Management?

​Research out of Georgia Tech examines the effect of hardiness zone shifts on tree distribution in the U.S., and the subsequent effect on trees as a strategy for cooling urban environments. Vegetative enhancement in the form of tree planting is a highly effective strategy for cooling urban environments, yet as cities continue to warm, the suitability of urban environments for some tree species is changing with shifting hardiness zones.

Does Tree Planting Pay Us Back? Lessons From Sacramento, CA

sacramento_streettrees
​Political support for urban greening has been fueled by research that quantifies the ecosystem services of planting initiatives. Major cities have been launching “million tree” campaigns, hoping that those trees pay us back. But do they? Only if the trees are properly selected, planted, and cared for. Read more... Read more
