Tree plantings and ceremonies also were held at public and parochial schools in each aldermanic district, and students whose schools are hosting an Arbor Day program displayed their artwork in the City Hall Rotunda. Arbor Day activities are planned to increase the awareness of the value and function of trees. Trees reduce erosion and stormwater run-off into storm drains that empty into the rivers and Lake Michigan. Trees improve air quality by absorbing carbon dioxide and releasing oxygen. They provide cooling shade that reduces energy costs.
Trees also reduce glare and noise and enhance property values.
The species of tree planted at each school are selected based on factors such as soil conditions and location to ensure a long, healthy life for the trees. Arbor Day is a community project developed cooperatively by the Mayor's Beautification Committee, the Department of Public Works Forestry Division, and Milwaukee's public and parochial elementary schools.
