The Emerald Ash Borer (EAB) is an invasive insect that uses ash trees as their primary food source and habitat. The EAB is best known for the unique pattern it leaves behind which has been decimating the Ontario ash tree population since 2003.
It is recommended that the ideal tree canopy for urban areas is between 30-40%. Based on a South Nation Conservation Authority 2016 report on Forest Cover, South Dundas currently has a total forest cover (including rural areas) of 31.5%, and saw a decrease in tree canopy between 2008-2014 by 4.1%. Of the forest cover 91% of it was located in treed lots, 3% in plantation farms, and 6% in hedgerows. It is estimated that 30% of South Dundas’ tree canopy is comprised of ash trees.
Even with the effective planning, implementation of control measures, and re-planting efforts, the Municipality’s forested landscapes will experience a dramatic change as a result of the ongoing invasion of this beetle. There is currently no pesticide or elimination method that has proven successful in the prevention or control of EAB. Through the implementation of specific actions outlined in the management plan, the Municipality will be better prepared to take effective efforts to minimize the risks, loss of benefits, and costs associated with EAB infestation.
