The nonprofit Greening of Detroit says the severe flooding caused by a recent water main break in Southwest Detroit may have affected the trees there, but they won’t know until May or June.

The Greening of Detroit plants city-tolerant trees that can sustain conditions like heavy pollution and flooding from clogged storm drains — or in this case — a water main break. The nonprofit planted nearly 250 trees in Southwest Detroit in 2021.

Fai Foen, director of green infrastructure at the Greening of Detroit, said the group chose urban tolerant trees to protect them from issues like this.

“We plant trees in Southwest and other parts of the city that might be exposed to pollution, air pollution, whether it’s manufacturing or a highway,” she said.

Foen says people are more of a danger to trees than the environment.

“You know, like, if it’s in a park, you know, the kids see the branch there may grab it. Or, like you can’t control for all the individuals that walk by a tree and just want to give it a good grab,” Foen said. “And I think the hidden trees that are being mown and maybe nicked at the base of the tree causes damage, but it’s like a death from like 1,000 cuts over a longer period of time.”

Foen said the flooding did not last long enough to have a lasting effect on the trees. But they won’t know for sure how much they were affected until the trees wake from their dormant period.
