The Emerald Ash Borer is a beetle from Asia and eastern Russia that was discovered in North America, south of the Great Lakes, as well as in Ontario in the early 2002s. However, several analyses have shown that it was probably present since the early 1990s. The first detection of Emerald Ash Borer in the province of Quebec was recorded in 2008 in the Montérégie region. It quickly migrated to the City of Montreal to appear in 2011. Since 2002, the Emerald Ash Borer has caused the loss of more than 100 million Ash trees with its infestation and continues to migrate northwest of the province.
