Moving, using and disposing of ash trees
Emerald ash borer (EAB) will continue to emerge from infested trees after they are felled. Moving infested wood can spread EAB along transportation corridors, and holding it at a marshalling yard or disposal facility can introduce EAB to the surrounding area, both hastening the spread of EAB within the community and region. Take steps to mitigate this by:
- Designating a disposal facility or marshalling yard to receive all ash wood; ideally it should not be adjacent to forests or woodlots with a component of ash. Select yards with large holding capacities to accommodate surges in wood volume.
- Using common transportation corridors for the movement of infested wood.
- Processing or destroying infested wood before adult EAB emerges from it (late spring/early summer). This can be done by burning or tub-grinding it.
Ash wood utilization
Ash wood can chipped and mulch can be used for municipal landscape projects or given to residents and commercial organizations. Unused ash mulch can be composted. However, large piles of wood chips pose a fire hazard so a plan for appropriate management should be instituted.
Ash wood can be used for value added products such as lumber since the beetle only damages the outer part of the sapwood. The following resources provide additional information about this. Wood can be processed at a sawmill within the quarantine zone; portable mills are also available in some regions. Use for biofuel may also be an option in some regions.

Moving ash wood
In order to limit the spread of EAB, there are federal regulations regarding the movement of potentially infested wood. If your community is within an area regulated for EAB you may not move ash tree articles outside of the regulated area without the consent of the CFIA.
