Fourth-grade students from Waller Elementary School stand ready with shovels as City of Burlington Public Works employee Joe Phillips positions a new maple tree for planting in Echo Park Friday. The tree-planting event was part of the city’s Arbor Day observance. In addition to learning how to properly plant a tree, the students got a lesson in forestry from several city employees who participated in the event that included the planting of five trees in the park. See Thursday’s Burlington Standard Press for more photos from the Arbor Day observance. (Photo by Ed Nadolski)
