Multitasking Street Trees
By Sonja Dßmpelmann


March 31, 2020

Since their systematic planting throughout the nineteenth and twentieth centuries, street trees have fulfilled various purposes in our cities. They have been considered variously as aesthetic make-up and creators of space; as territorial markers and instruments of defense, emancipation, and empowerment; as sanitizers and air conditioners; as upholders of moral values; as economic engines, scientific instruments; and as ecological habitat. Although street trees are successful multitaskers, which at most times have simultaneously fulfilled various purposes, different functions have been considered particularly important at different times.

Appreciating the need for — and the beauty of — the urban forest

By Adrian Higgins 

The Washington Post, December 11, 2019

One thing seems certain: The need for street trees is only going to get greater. They shade, they cool, they grab carbon from the atmosphere. Oh, and they can be beautiful if spared the butchery of life with the aerial power line. A 2015 study confirmed what we might have already known — people who live in the shelter of mature trees are healthier than folks in neighborhoods that don’t have them.

Why trees aren’t just colorful fall features for our region’s neighborhoods

Washington is an appealing place to live and work in part because of its greenness, its preserved natural ecologies as well as its designed landscapes. Especially valuable are the millions of trees, and not just for their beauty and colorful tree canopy transformation in the fall. Trees greatly benefit environmental and economic health.

Trees throughout the city add real estate value as well as significant aesthetic and ecological value. Ask any real estate broker or developer, and they will tell you that properties with trees typically are worth more than those without trees. Homes on tree-lined streets sell for more than homes on treeless streets.
