This past spring, I had the opportunity to work as the Naturalization Assistant at LEAF and support their community planting events. At these events, we worked with LEAF volunteers and community participants to plant 1,250 native trees and shrubs in Richmond Hill and King. I’m excited to share my experiences of seeing how different people came together as a community to make a lasting impact on the environment.

Ever wonder what it’s like to be the best at everything? The majestic bur oak can tell you! Not only is it one of Ontario’s largest growing and longest living trees (it can live up to 300 to 400 years!!), it’s also the most common, widespread, cold-tolerant (burrr!) and drought resistant of all native oak species in Canada. As if that wasn’t enough, its acorns (fruit) are among the largest of all native oaks. The bur oak is defi-nut-ly a true masterpiece!
