Local Enhancement & Appreciation of Forests


Our Backyard Tree Planting Program offers native trees and shrubs to property owners at a subsidized cost.






Bicoloured Agapostemon (Agapostemon virescens) on yellow flower
Our goal at LEAF is to teach people about the value of the urban forest. Remember, it’s not just humans who benefit from trees in our cities, but also a wide variety of urban wildlife – including bees! We hosted a virtual event to explore bee-friendly trees in Richmond Hill and steps we can take to support local pollinators. Here are some of the most buzz-worthy takeaways from our event.
Female spongy moth
Spongy moth has become an unwelcome guest throughout southern Ontario. Native to Europe and Asia, this invasive moth may be more recognizable by its former names, the gypsy moth or LDD (short for Lymantria dispar dispar). In 2021, we saw a spike in the spongy moth population and with it, extensive tree defoliation in certain areas. While this non-native pest may be here to stay, here’s how you can do your part to identify it and help reduce its impact.
improer vs proer staking
Staking a young tree after planting has been a long-standing practice aimed at providing additional support and protection for the tree while it establishes. Contrary to this popular believe, however, many trees are often staked unnecessarily and incorrectly.
