Parks Department begins replacing trees in Humboldt Park By FOX6 News Digital Team Published article MILWAUKEE - Milwaukee County Parks forestry crews have been busy planting trees in the 73-acre park, much to the delight of Bay View residents and park visitors. According to a press release, beginning in early April, crews began planting River birch, Elm, Maple, Ironwood, Basswood, Chestnut, and London Planetrees around the lagoon in the center of the park, near the Lilypond near E. Oklahoma Avenue, and on the hillside along S. Logan Avenue. "We were expecting a dozen trees would be planted this spring, but the county upped that to 22," said Mike Bubolz, president of Humboldt Park Friends (HPF), a nonprofit volunteer group working to improve the park. "There will be another 20 to 25 hardwoods planted this autumn, with more scheduled for next year."
