Michigan cities take a tree census

People sit in the shade of trees at Rosa Parks Circle in downtown Grand Rapids. The city values the 61,000 trees within its boundaries at $71 million.

Grand Rapids, Adrian and Ann Arbor are taking part in a tree study that could help other Michigan cities assess their own urban forests. The goal is to make a tree assessment more accurate and affordable for cities.

Grand Rapids spent tens of thousands of dollars to find more information about the city’s trees. They came away with valuable information like how much greenhouse gases and water runoff the trees absorb. But city owned trees make up only a tiny portion of the overall urban forest in Grand Rapids.

Tyler Stevenson is the city forester. He says they discovered more than half of Grand Rapids’ trees are maples.

“Is that true for the entire community? We don’t know. And it’d be interesting information and it would also help to increase the awareness of the public on how valuable the trees on their property are.”

Federal officials will use the data from the study to enhance existing software. Other communities in Michigan will be able to use that software for free to calculate data about their own trees.
