In 2015, TreeCanada and sponsors U-HAUL and Telus partnered with The City of Peterborough to offer a subsidy to approved home and property owners to treat their ash trees against the Emerald Ash Borer. The initiative offered owners of private ash trees a subsidy of up to $3.00 per centimetre of trunk diameter to treat with TreeAzin biopesticide against the Emerald Ash Borer. The scheme ran in two phases, the first was for owners of up to 5 ash trees until 1 July 2015 and extended to owners of 6 or more ash trees until late August.

The initiative launched on May 28th 2015 and continued through until late August 2015. Many owners of private ash trees took advantage of this generous subsidy as an incentive to treat their ash trees and help preserve the urban forest of Peterborough. 

This is how the incentive worked in 2015 and for 2016:

If you have one or more ash trees on your property, complete details about the trees on a TreeCanada application form (details available at the time).

The City of Peterborough receives the form and visits to inspect your ash tree or trees and determine if it or they are suitable candidates for treatment. The City arborist will also take a trunk diameter measurement. The trunk diameter is recorded in centimetres and is referred to as Diameter at Breast Height or DBH.

As the owner of the trees you will then arrange for a Licenced BioForest Service Providerlinks to external site to treat your ash tree or trees with TreeAzin at the rate of 5ml per centimetre of DBH. Please note that TreeAzin is the only pesticide that was used for the 2015 initiative being a natural product with very low environmental toxicity.

Once your tree or trees have been treated with TreeAzin by a Licenced BioForest Service Provider at the rate of 5ml/cm DBH and you have a paid receipt you submit a copy of this to the City of Peterborough, Infrastructure and Planning Services Department who will authorize payment from TreeCanada at the rate of 50% of the treatment cost up to a maximum of $3.00/cm DBH.

As an example, if your ash tree is 30cm trunk diameter or DBH and you pay $6.00/cm to get it treated, you will be paying the contractor $180.00 plus tax but will receive back $90.00 from TreeCanada. If you pay the contractor more than $6.00/cm you will still only receive $90.00. If you pay the contractor less than $6.00/cm you will receive 50% of the pre-tax cost.
