The Emerald Ash Borer (EAB) & Richmond Hill's Ash Trees

Image: wood chip pile Free Wood Chips (Local Use Only)
Looking for wood chips for your garden? Free wood chips are available for pick up at Richmond Green, 1300 Elgin Mills Road East. The pile is located at the west end of the parking lot in front of Tom Graham arena. Please help yourself.

Using woodchips in your garden means less weeding, less watering, faster plant growth, protection from overheated soils during hot summers, added nutrients to your soil and less bruised fruit under fruit trees!

Please be advised that these wood chips may contain ash trees that have been infected by the Emerald Ash Borer (EAB). As such, we ask that you only use them locally. This will help stop the spread of EAB.

About the Emerald Ash Borer
The Emerald Ash Borer (EAB) is a non-native, invasive insect that attacks and kills ash trees. While EAB poses no health risk to humans or pets, ash trees of all species and sizes (with the exception of Mountain Ash) are susceptible to attack. EAB is currently posing a major economic and environmental threat to urban and forested areas across southern Ontario. It is estimated that millions of ash trees have already been infested and killed by EAB since it arrived in North America.

EAB in Richmond Hill
EAB infested trees were discovered on King's Cross Avenue in Richmond Hill in March 2011. Its presence was confirmed across York Region in 2012.

Ash trees are widespread on public and private properties throughout Richmond Hill. They contribute significantly to neighbourhood and park aesthetics, provide shading and cooling effects and are important components of local ecosystems.

What's Going on in 2014
The Emerald Ash Borer (EAB) is expected to kill all of the ash trees in Richmond Hill in the next 3 to 5 years. The Town is implementing a management strategy for ash trees on public property. Here's what's going on in 2014:

Town staff have completed assessments of all municipal ash trees along streets. Dead or dying trees will be removed in late summer/early fall.

Trees that were treated with pesticide in 2012 and were deemed healthy were treated again this summer.

A Parks and Open Space Ash Tree Removal and Replacement Plan has been completed. Ash tree removal in parks is expected to begin in late summer/early fall.

Replanting of trees will begin in spring 2015 and may take up to 2 years to complete.

Residents with trees adjacent to their property that are scheduled for maintenance (pesticide treatment, removal, stumping or replacement), will receive a notice in the form of a letter and/or a door hanger, 24 to 48 hours prior to the work being done.

Healthy and infested ash treesAsh Trees on Public Property
Richmond Hill values its natural tree cover and is committed to protecting it. In response to the threat of EAB, Town staff have developed an EAB Management Strategy for trees on public property, which was approved by Council in October 2011. The Management Strategy aims to reduce the significant aesthetic, environmental and financial impacts of EAB on Richmond Hill through monitoring and treatment, ash tree removal and replacement, along with communication and public awareness. Implementation of the Management Strategy is underway.

The Town is treating some of the largest and healthiest ash trees along streets and in Ash trees treated with TreeAzin are marked with a tagparks with pesticide (TreeAzin™) to help minimize damage caused by EAB. However, not all ash trees will be treated by the Town. Property owners may apply for a permit in order to treat town-owned ash trees adjacent to their property with TreeAzin™, at their own expense, by completing the application at the link below.

Application to Treat Town-Owned Trees [PDF]

Completed application forms can be emailed to naturalenvironment@richmondhill.ca; dropped off at Richmond Hill's main Municipal Offices, 225 East Beaver Creeek Road, 5th floor; or mailed to Town of Richmond Hill, Attention: Natural Environment, 225 East Beaver Creek Road, 5th floor, Richmond Hill, ON L4B 3P4.


Ash Trees on Private Property
Property owners are responsible for trees on private property. If you have an ash tree on your property and suspect an EAB infestation you are encouraged to consult with a professional arborist (these can be found in the Yellow Pages and other business directories). You should choose an arborist certified with the International Society of Arboriculture (ISA), registered with the American Society of Consulting Arborists (ASCA), or Provincially qualified Arborists and Utility Arborists by the College of Trades. Make sure to ask if there is a fee for inspection and quotes, as some companies provide these services free of charge.

It is recommended that property owners ask about options for tree protection, tree removal* and tree replacement. In addition, ensure that you get multiple estimates for any tree work.

*Permit fees for ash tree removal will be waived for the duration of the EAB Management Strategy (10 years), but an application must still be submitted to obtain a permit. Please visit RichmondHill.ca/TreeBylaw for more information.
