Introduction Trees play an invaluable role in enhancing city environments, providing everything from energy savings to climate-change mitigation. But it’s important to remember that not all urban forests are created equal — and evaluating trees by their quantity as opposed to their quality is to display a fundamental misunderstanding of city trees’ potential worth. Healthy,… More
This post includes a number of statistics found in an in-depth study titled “Financing Green Infrastructure” published by ICMA (International City/County Management Association) in May 2022 — click here to read the report in full. Introduction As the social and environmental benefits of green infrastructure (GI) gain more and more traction among municipal project planners,… More
Introduction The first licensed airfield in Canada, City Centre Airport opened in 1927 on 144 acres of land just north of Downtown Edmonton. Serving as a military airbase during the Second World War, it became a stop on international passenger flights between North America and Asia in the 1950s. As jet technology progressed during the… More
Introduction From New York City’s Metropolitan Museum of Art to Wembley Stadium in London, DeepRoot has helped ensure the success of green infrastructure projects in big cities across the globe. But these high-profile initiatives are only part of our story — Silva Cells grow large trees in towns big and small, partnering with designers, engineers,… More
A recent research study conducted by Bartlett Tree Research Laboratories tackled the question of the best methodology to grow trees in cities, with the ultimate goal of reaping benefits that mitigate the impact of climate change. The study (Comparison of Tree Responses to Different Soil Treatments Under Concrete Pavement) was produced by Dr. E Thomas… More
Introduction When we talk about low-impact development and design today, the term “suspended pavement” is frequently used — but rarely defined. It’s important to understand this practice within the field of green infrastructure, so let’s examine what suspended pavement is as well as its history, uses, composition, and case studies. What is Suspended Pavement? Suspended… More
One of the most common questions posed when beginning an urban forest project is: how wide do tree roots grow? According to studies conducted by Colorado State University, most tree roots occupy an area two to four times the diameter of the crown. Other research done at Iowa State University suggests that roots may extend… More
Introduction The question of how much soil is required to grow a big tree is one that has been debated among arborists and landscape architects for decades — and the answer isn’t black and white. Space, pollutants, and engineering requirements are all major considerations that affect the growing conditions of urban trees. And, other than… More
A previous blog entry, Healthy Soils for Healthy Trees, discussed the importance of preserving soil structure from being destroyed by compaction. Together, soil texture and soil structure have the greatest influence on pore space in soil, and how easily air, water, and roots can move through a soil. Many people are aware of what soil… More
You don’t need much experience in arboriculture or landscape design to notice that planting trees in cities is very different from planting trees in forest environments. There are many reasons for this, but perhaps the biggest is the difference in composition of the soil.
Soil. Stormwater. Sustainable Infrastructure.
