Did you know that the City of Franklin DPW takes care of all trees in the City right-of-way? With the recent retirement of Jerry Schaefer, the Common Council designated Tom Riha as the City Forester. Tom is a 2005 graduate from the University of Wisconsin-Stevens Point, where he earned a double major in Urban Forestry and Forest Management. Tom also holds the credential of being a Certified Arborist and has worked for the Franklin DPW since 2010.

In addition to his other duties as a Light Equipment Operator, Tom is a tremendous asset to the City in assessing, pruning, removing, and managing trees. He assisted in the expansion and implementation of the City’s tree inventory to ensure it is up to date and accurate, utilizing the City’s GIS system. Tom has been instrumental in many other items that have qualified the City to be designated as a “Tree City USA” for 16 years straight.

Tom has also been heavily involved in the City’s efforts to combat the Emerald Ash Borer that has affected so many trees in Franklin. To date, approximately 3,000 affected Ash trees have been removed by DPW and another 575 are scheduled for removal. To combat future tree diseases from devastating the City like the Emerald Ash Borer and the Dutch Elm Disease, the City has established a goal of having one species comprise no more than 10% of the total tree inventory.

Tom has finished the 2017 tree report and the City maintains 9,690 trees, comprising of 99 sub-species of trees. The Maple Family comprises 33% of the inventory and includes the Amur Maple, Box Elder, Freeman Maple, Red Maple, Silver Maple, Sugar Maple, and Norway Maple. Tom recommends that residents who are planting trees on their property select from some of the minority species to help the overall tree diversity in the City. Below is a table of recommended species for Franklin street trees.
