Emerald Ash Borer (EAB)

You are here

Like many municipalities across southern Ontario, EAB has reached Georgina and much of York Region. EAB is a highly invasive insect that attacks and feeds on all species of ash trees, killing them within one to three years. Ash trees are widespread on public and private properties throughout Georgina, accounting for 19 per cent of the Town's tree population. More information on the EAB threat is available through York Region.

Georgina's management plan

Under the Town's Phased Ash Tree Removal and Replacement Program, the Parks and Facilities Division is currently removing municipally owned trees on a priority basis as determined by any danger/threat to the public or public property. Once an assessment of an ash tree on municipal property has been completed, and it's determined that it will be removed, it is tagged with an orange marking. On regional roads, trees will be tagged with a green marker.
Replenishing the removed trees will occur during usual planting seasons in the fall and spring, and a different species of tree will be planted. Trees are being replaced at a one to one ratio and may not necessarily be planted in the exact location of where a tree was removed. In some cases, a more suitable location will be determined.

Ash trees on private Property

Ash trees that are on private property are the responsibility of the property owner. If a resident decides to remove an ash tree on their property, the cost will be incurred by the owner. Infested trees that are located on Town-owned property in front of homes will be removed by Municipal/Regional forestry staff and replaced at no cost to the homeowner.
If you have ash trees on your property, it is recommended that you obtain the services of an ISA Certified Arborist as:
  • It can be difficult to tell if a tree is infested
  • By the time signs or symptoms appear in trees, it is often too late to treat
  • They can safely remove and dispose of wood waste
  • Insecticide treatments work best if applied before trees are infested/when infestation is at an early stage
For a list of certified arborists in your area, visit TreesAreGood or call 1-888-463-2316.
Don't wait to remove an infested ash tree - once it dies, it quickly becomes brittle and can damage your property or a neighbours.
