Plenty of Canadians will likely hit the road this long weekend to enjoy cottages, campfires and fireworks celebrations.
The Nature Conservancy of Canada says it doesn't want to be the 'fun police' but it's encouraging people to buy and burn local firewood rather than move it or transport it in their vehicles.
They're warning people may be unknowingly or unintentionally spreading the invasive Emerald Ash Borer beetle.
It is spread through transporting firewood.
The Conservancy says the Ash Borer is destroying trees in Canada and has been rapidly spreading in its distribution since 2002.
They say in the past 18 months, the beetle was discovered in Nova Scotia, New Brunswick and Manitoba.
A federally approved biological control is being used in areas across the country where tiny wasps are released into infected trees to kill the eggs of the Ash Borer.
The Grey Sauble Conservation Authority is currently using the wasps in the West Rocks Management area.
The conservancy says in a statement “Ash trees are in many cities, towns and forests and along water ways but also very important to our economy. Ash trees are used to make furniture, flooring, electric guitars, baseball bats, hockey sticks, baskets, snowshoes and also make durable tool handles.”
In Southampton in 2017, a large swath of ash trees were cut down due to infection. This summer, the popular Deer Run Trail in Huron-Kinloss will be closed for the removal of 160 ash trees. The beetle has also been found in Owen Sound and Meaford.
