Tree canopy’s density indicates wealth of D.C. neighborhoods

There’s a surprisingly telling barometer of income disparity in the Washington region that rarely arises in conversations about the haves and have-nots.

Trees.

Comparing tree-cover with income levels

In country’s most affluent region, numbers of poor on the rise

Newly released census statistics show that poverty rates rose last year in the Washington suburbs.

Seven of the nation’s 10 wealthiest counties are in the D.C. region, according to census numbers.

Local areas were singled out as being among the most diverse places in the country.

A clear fault line that begins at upper 16th Street in Northwest and follows the Potomac River south of the city separates leafy neighborhoods from communities with fewer trees, data on the region’s tree canopy compiled by the University of Vermont’s Spatial Analysis Laboratory and analyzed by The Washington Post show.

To the west of the line, in the affluent Northwest quadrant of the city and similarly well-heeled Virginia and Montgomery County suburbs, trees are abundant and the land well-planted, the analysis shows. In the lower-income areas of the District and Prince George’s County to the east, the tree canopy is sparser, and there is far more open land.

Put more finely, in areas of the Washington region with typical household incomes below $60,000, more than a quarter of residents live with fewer trees and more open space where they could grow, the analysis shows. Where typical household incomes are above $120,000, some 60 percent of residents live in leafy neighborhoods that are well-planted.

The divide is greater within the District — which has one of the highest levels of income inequality among the nation’s cities. Nearly 40 percent of residents in low-income areas live in places with fewer trees and more empty spaces. Meanwhile, 80 percent of residents in upper-
income areas live in well-planted neighborhoods, according to the Post analysis, which rated neighborhoods on a percentage scale that reflects existing trees and open space that could in theory be planted.

The reasons for the divide are complex, environmentalists say. Although there are always exceptions, people who own their homes are more likely than renters to plant trees and more likely to lobby their governments and others to plant trees in public parks and along streets near their homes, experts say. People who are more affluent and educated also are more likely to be knowledgeable about the benefits of trees, which include mitigating air pollution, reducing mental stress, saving energy by shading homes, slowing storm water and increasing property values.

“There’s a strong relationship between how many dollars you have and how many trees you request to be planted in your neighborhood,” said Earl Eutsler, supervisory forester for the District’s Urban Forestry Administration. Eutsler mapped requests to the city for trees along streets last year and found a heavy concentration in Northwest and Capitol Hill but merely a sprinkling in the city’s poorest wards.

Doris Gudger of Anacostia is among those who see little to like about lots of trees. When city crews showed up one recent day and planted some in front of her rowhouse in Southeast Washington, she wanted them gone.

The pollen would aggravate her allergies, she said. The leaves would be a pain to rake. The shade would draw drug dealers. And, she feared, soon would follow affluent gentrifiers and higher taxes, pushing out older residents like herself.

“To me, the trees create more problems than when they weren’t there,” said Gudger, 61, a retired secretary.

But environmentalists in the District need the buy-in of residents.

The city has often been praised for its urban forest, boosted by trees on the federally owned Mall and in Rock Creek Park. But only 36 percent of the overall canopy remains, a decrease from 50 percent in 1950. The decline is due in large part to development, a trend that can also be seen in the suburbs.

The city and nonprofit groups have been trying to plant at least 8,600 trees a year in the District in an effort to increase the canopy to 40 percent in the next two decades. Working with neighbors is becoming more important in preserving the tree canopy, because much of the plantable land left is in private yards rather than in parks and other public spaces.

But urban foresters hoisting their shovels to plant in underserved areas say they frequently run into residents like Gudger, who worry about whether the city will help maintain the trees and other issues.

“By and large, in areas where people have more disposable income, you’ll see greener areas and a better understanding of what trees and greenery provide,” said Mark Buscaino, executive director of Casey Trees, a local nonprofit organization that has been working to restore the District’s tree canopy for more than a decade.

Over the years, Buscaino said in an interview, Casey Trees has learned the hard way that it does no good to plant trees if there is no community support for them. In its early years, the group planted dozens of trees that ended up withering and dying because no one watered them. Now, the group does tree plantings only when a homeowners association or community group asks for help, Buscaino says. Over the years, that has helped cut the tree mortality rate to 16 percent.

But some environmentalists argue that it’s not enough to just show up at community meetings, extol the virtues of trees and expect the residents to embrace planting them. The foresters often are perceived as outsiders, and that can make people apprehensive, says Dennis Chestnut, a Casey Trees volunteer who is also the executive director of Groundwork Anacostia, an environmental group.

Taking the time to convince individuals can make the difference, he says.

When Xavier Brown, 27, director of urban agriculture at a nonprofit group called the Green Scheme, which works to raise environmental awareness in the District, planted a community garden last year in Lincoln Heights, he at first found little enthusiasm among the neighbors.

He spent a lot of time trying to figure out how to make gardening look cool to the younger residents. He even tried the visual stunt of planting a sunflower in a Ken Griffey Jr. Nike shoe.

After residents got to know Brown, a District native, and sampled the abundant vegetables that poured out of the garden, a tree planting on the property this spring was much better attended. He turned it into a mini-block party, with kale salad, sandwiches and a DJ.

Turns out there were any number of groups willing to help, he says, but it took him a while to figure out whom. “You really have to know how to network with people and have to talk to the right people to get the community involved,” said Brown, who also is a citizen forester with Casey Trees.

One recent Saturday, Brown and about 100 others gathered in a vacant lot in Glenncrest, a development of about 200 townhouses painted in primary colors in Southeast that has a mix of renters and live-in owners. Casey Trees had donated 19 trees — shade trees and fruit trees — for the vacant lot, once a magnet for litter and weeds. As the father of one of the homeowners played jazz on a boombox, the volunteers wielded shovels and flung piles of dirt. The scent of topsoil and mulch filled the spring air.

Residents of the development said they were excited about the additions to their neighborhood, although many seemed uncertain about who would assume stewardship of the trees after they were planted. Some thought Casey Trees staff members would be returning to maintain the trees. In fact, that job would be up to the residents.

“This is ours, our own personal tree?” Jalen Webb, 9, asked his mother Dina Webb, a homemaker, after they had planted an American sweet gum.

She nodded and gave him a hug. Before the city cleared the lot and the tree planting began, “it looked bad. It didn’t look good when you rolled by,” she said. “Now, it’s going to look nice. We got to keep it watered.”
