Emerald ash borer

  • Ash trees are commonly found in streets, parks, and forests throughout Ottawa and the rest of Ontario. (Figure 1). There are three species in Eastern Ontario: white, green, red and black ash.

  • Due to the Emerald Ash Borer, a Ministerial Order has been issued by the Federal Government restricting the movement of wood out of Ottawa and Gatineau. The City of Ottawa is asking that you do so with care. We all play an important part in limiting the spread of this invasive species.

  • See information for woodlot owners to combat Emerald Ash borer.

  • Emerald Ash Borer is a non-native, highly destructive wood-boring beetle that feeds under the bark of ash trees. Find out how to identify ash trees, how to identify infested ash trees, and how to slow down the spread of the emerald ash borer.
