The Queensway is a major thoroughfare in Toronto that, after its construction in the 1950s, incorporated streetcar service as well as vehicle traffic. Starting in the 2000s, there was an increase in residential development, and the area has undergone new construction projects in order to accommodate a growing population seeking easy access to downtown. During this… More
Bioretention media is an important topic in the design world. As green infrastructure solutions gain acceptance, there is increased focus on finding the most effective media for on-site stormwater management. But there isn’t (yet) a lot of agreement on what the media consists of, and how to make it both functional for stormwater while being… More
Thanks to widespread efforts to raise awareness of the large declines in bee and Monarch butterfly populations, most people are aware of the need to protect pollinators. Monarch butterfly populations have declined 90% in the last 20 years. Bees and other pollinators are in trouble too. Primary causes of the drastic declines in pollinator populations… More
In part one of this series, we gave recommendations for how to address tree maintenance needs in a smarter and more financially (and ecologically) sustainable way. In part two, we shared specific lessons from other cities that I was aware of – and asked you to reach out and share your experience. Today, we’ll share… More
After years of neglect, infrastructure is again being discussed as a major priority for public investment in many jurisdictions. Ontario’s new Climate Change Strategy calls for the building of green infrastructure, among other things, to help us mitigate and adapt to climate change. In the past, public investments have largely been directed to only grey… More
We all know that street trees have value; you frequently hear statistics about how much energy savings they offer, or how much they add to the selling price of a home. And in some cases, for example with heritage trees or in environmentally sensitive areas, trees are identified as assets for planning and permitting purposes…. More
Mei Ling Hui has been with San Francisco’s Department of Environment since 2007, first as the Urban Forestry and, more recently, the Agriculture Coordinator. Along with her main role in those programs, she provides support to the Climate, Environmental Justice, and Toxics Programs, serving at the intersection of many public stakeholders. She provides staff support to… More
“Right tree, right place” is easier to do in Ohio thanks to the Urban Site Index (USI), a tool for assessing soils and planting sites developed by OHDNR regional urban foresters Alan Siewert and Stephanie Miller. By observing various tree species in various sites, site ratings for different tree species can be developed for various… More
Having started with the simplest ways to quantify stormwater benefits of Tree Stormwater Control Measures (SCMs), we now arrive at the most complex ways. Part 1 of this series provided an overview of various ways to quantify stormwater benefits of Tree Stormwater Control Measures (SCMs), and gave an overview of tree benefits calculators and stormwater… More
Landscape architects have been designing options to improve rooting conditions for urban trees for decades. In that time, many ideas have been developed, with varying costs (for the clients) and outcomes (for the trees and the site at large). In summer 2015, Dr. Tom Smiley with Bartlett Tree Laboratories began a research study that is… More
