Volunteers and community leaders in Marshalltown are planting trees to provide more shade and save energy. The local project is part of the statewide Trees Forever and Alliant Energy Branching Out community tree-planting program. This is the 21st year that Marshalltown has participated in this program. This years project plans to plant 18 trees at Riverview Park, six trees at Assistance League Park and five trees at MEGA 10 Park. Many of these tree plantings will replace trees that were removed due to damage sustained during storms in recent years.
