The annual elm pruning ban takes effect Saturday across the province.
The measure is intended to help curb the spread of Dutch elm disease, a fungus spread by elm bark beetles.
“With warmer weather, these tiny beetles become more active and are attracted to fresh cuts on trees, making an infection more likely,” the Ministry of Environment said in a statement.
The ban runs until Aug. 31.
Pruning trees before or after the ban period can help keep them healthy and resistant to disease, the ministry said. Elm bark beetles breed inside dead or dying elm wood, so pruning before or after the ban can help eliminate their habitat and reduce the beetle populations.
“You are allowed to completely remove an elm tree during the ban period, but it’s critical to dispose of all elm wood promptly and properly,” the ministry added. “Contact your local municipality to find out where the designated disposal site is in your area.”
Transporting wood can also spread Dutch elm disease, the ministry cautioned.
“That’s why it’s illegal to use, transport, store or sell elm firewood.”
