Some Nova Scotia trees appear to be getting a head start on fall.
Leaves are already hitting lawns, sidewalks and streets in some communities, but experts say it does not necessarily mean autumn has arrived early.
One likely cause is tar spot, a fungal issue that commonly affects Norway maples.
The fungus creates dark spots on leaves and can cause them to drop before the usual fall colour change.
Experts say the issue can be easy to notice, especially because Norway maples are common in many urban areas.
The good news is tar spot is generally considered a cosmetic issue and is not expected to kill otherwise healthy trees.
Wet spring weather can help create the conditions for the fungus to spread.
People who want to reduce the chances of it returning next year can rake up and remove fallen leaves before winter.
Early leaf drop can also be tied to broader tree stress, including changing weather patterns, drought impacts, invasive insects and disease.
Tree experts say communities can build more resilient urban forests by planting a wider variety of tree species.
That way, if one insect, fungus or disease targets a certain kind of tree, the impact is less widespread.
