A couple of weekends ago, our Tree Identification Tour explored the incredible diversity of tree species found in the valley and a few of the urban pressures they face as part of Toronto’s urban forest.
Towering willows greeted us upon our entrance into the valley, drawing the skyline along the gurgling riverbank and quieter Milne Pond. As a water loving species that can absorb thousands of gallons per year, these willows act as a gentle reminder of one reason why this natural area is so crucial to storm water management in our city.
At the trail entrance, we were also welcomed by the butternut, a species at risk of extinction that has incredible, large lemon-shaped fruit and lush compound leaves. Further down the newly paved trail, we passed a smattering of native oaks, maples, ashes, and my favourite find – a Kentucky coffee-tree. Touring through the space, we also found a great example of sugar maples naturally regenerating under a section of the invasive Manitoba maple’s canopy. Over the past decade, numerous community plantings of native species and stewardship efforts aimed at controlling invasive species have helped native species fight for their rightful place as part of the valley’s ecosystem.
It’s surprising to imagine the transformation the Hollow has undergone from a forested valley to an industrial site and back again in the past century. The spot’s rich history as host of the bustling Milneford Mills community and a former ski hill is barely visible – save for remnants of two ski rope tows.
It was nice to meet several members of the tour that had come back to valley they once loved as a youngster for the first time since its earlier ski-hill years. The City’s Master Plan for the site has done a great job at not only enhancing its natural beauty but also showcasing Milne Hollow as a vital natural corridor for recreational enjoyment – certainly the perfect spot to learn your trees!
