Each year, the city removes many, many ash trees infested by the emerald ash borer (EAB), a destructive insect pest. What do we do with all this wood? We use it to make furniture or transform it into chips to improve the soil!
The recovery of ash wood gives it a second life. Hard, compact and very resistant, this wood lends itself very well to woodworking projects such as outdoor furniture for parks.
Montréal is able to make significant savings by using ash wood in ways other than turning it into wood chips. It also helps to sequester the carbon stored in the wood, which reduces greenhouse gases (GHGs) responsible for climate change.
Large ash trees are cut into boards after removing any part infested with EAB larvae. The boroughs and related cities involved use ash boards and mouldings to renovate buildings and build indoor and outdoor furniture, such as benches.
Small diameter ash trees are crushed on site to remove all traces of the borer. The chips are used to amend the soil.
Where does the ash wood come from?
The wood is recovered from wooded areas where dead ash trees have been felled to ensure the safety of hikers. The parks concerned are: Parcs du Mont-Royal, de Tiohtià:ke Otsira’kéhne, Angrignon and Frédéric-Back and the Du Bois-de-Saraguay, De la Pointe-aux-Prairies, Du Cap-Saint-Jacques, Du Bois-de-L’île-Bizard, Du Ruisseau-De Montigny and De l’Île-de-la-Visitation nature parks.
