The City of Marion's Tree Program was established to effectively manage the public's tree reources, which contribute to the aesthetic, economic, and environmental well being of the community. All street trees (trees within the public right of way) and park trees are managed under the City's jurisdication. The program also serves as a source of information to help residents improve their knowledge of proper tree selection, care, and benefits in an effort to protect, preserve, and restore the urban forest canopy community-wide. This is accomplished through the leadership of the City's Tree Board
. The City of Marion has been recognized for over 23 years as a Tree City USA for its efforts to preserve and enhance the urban forest.
