Monitoring for Success: Improving Biodiversity through Naturalization Plantings

Planting native trees and shrubs on public lands has many long-term benefits, including increasing essential habitat for local wildlife. To ensure our efforts are successful, we’ll be monitoring the impact of our tree planting events on plant biodiversity over time. Thanks to support from Ontario Power Generation’s Regional Biodiversity Program, we can assess each site as it establishes itself and adaptively improve our future naturalization efforts when needed.

Community Tree Plantings for Biodiversity in York and Durham Regions

This fall, LEAF staff and volunteers have begun planting native trees and shrubs in York Region as part of a larger, three-year project to increase biodiversity on public lands in York and Durham Regions. Among project activities are planting 6,000 native trees and shrubs, monitoring sites before and after planting and engaging local community members. These activities are made possible in part, thanks to support from Ontario Power Generation’s Regional Biodiversity Program.

The Main (and Secret) Reason I Joined the LEAF Young Urban Forest Leaders

If I asked you to close your eyes right now and picture a tree, what would it look like? Can you describe it: Its size, its shape and its leaves? My brain-tree looks like a pine, and there’s a very good reason for that. It’s also the secret reason that I wanted to join the Young Urban Forest Leaders (YUFL) Program. But to understand why my brain-tree is a pine, and why that made me want to spend a summer learning about urban forestry, I have to tell you a little story.

The Importance of Pruning Young Trees

What comes to mind when you think of pruning? For many people, it’s a topiary shrub clipped into an ornamental shape. Though we often think of pruning as an aesthetic practice, it actually serves a much wider purpose. Each pruning cut has the ability to change the growth pattern of a tree forever; making pruning young trees an essential practice in order to maintain health and encourage a strong structure as they mature.
