City marking ash and hazard trees for removal starting October 1

The City of Guelph will be marking public trees in woodlands that are hazardous and ash trees infested and killed by the Emerald Ash Borer starting October 1, 2018.

Hazard tree removal will happen in:

  • Ellis Creek Wetland
  • Mitchell Woods Park
  • Marksam Park
  • Margaret Greene Park
  • Hadati Creek (Watson Parkway N to York Road)
  • Ridgeway Greenway (Arkell Road to Jenson Boulevard)
  • Westminster Woods

Trees will be marked with an orange “X”, indicating they will be removed. Removals starts in early November and continue into spring 2019, with any remaining trees removed in fall of 2019. This work is being done as a part of the City’s Emerald Ash Borer (EAB) Plan and hazard tree removal operation.

Woodlands, trails, roads and sidewalks will temporarily close during the work, limiting access to trails, parks and natural areas.

The City will also remove invasive buckthorn in the same areas using herbicide treatment to create the best opportunity for natural regeneration and/or replanting and restoration efforts.

Hazardous limbs and trees from private property are the responsibility of the owner. Under the City’s Property Standards By-Law, residents are asked to reassess, remove and replace any ash trees impacted by EAB or hazard trees.

About the Emerald Ash Borer Plan

The emerald ash borer (EAB) is a highly destructive, non-native, wood-boring beetle that feeds under the bark of ash trees, ultimately killing them. EAB is expected to destroy close to 100 per cent of Guelph’s untreated street, park and woodland ash trees. For more information, visit
