The City of Thunder Bay's Forestry and Horticulture Section manages well over 20,000 trees within the city limits. These trees are important assets of the city that provide scores of benefits to citizens and other infrastructure. 

For a comprehensive look at the state of urban forestry in Thunder Bay, refer to the city's most recent (2011) Urban Forest Management Plan (UFMP). Our goal is to create a diverse urban forest in the City of Thunder Bay along streets and in our parks. Different species and ages of trees can better defend against natural and human-made threats. Unfortunately, a lot of trees struggle in our northern urban environment, which can shorten their lifespan and reduce their growth.

Benefits of urban trees

Trees in urban areas are especially important for citizens living in the city for many reasons. Without them, the quality of the air would be reduced, rainfall events would be more drastic, and energy costs for homes would increase, just to name a few. Below is a summary from the UFMP of the dollar-valued benefits that trees in Thunder Bay provide each year.

Invasive species

Invasive species like the emerald ash borer, japanese knotweed, and himalayan balsam, can wreck havoc in the city. Find out how to report them and how to avoid their spread.

Plant a tree

City boulevards are planted by qualified, city-directed contractors with a specific species of a specific size for each location. Please do not plant trees on your boulevard. We generally do not plant conifers on boulevard as they easily become line of sight issues. If you'd like a tree on your boulevard, you can request a tree.

Planting a tree of your own? We reccommend you follow our standards for planting a tree. Find out which plant species that you shouldn't plant in Thunder Bay with our Grow Me Instead Guide for Northwestern Ontario
