Introduction Green infrastructure has become a widely adopted component of stormwater treatment initiatives across the globe — but can GI be integrated even in the tightest-space built environments, where numerous priorities are competing for the same area? Yes! With a little creative design and the right strategic partners, GI can be utilized in just about… More
Introduction A red maple tree rises forty feet above the park across the street from my Minneapolis house, a centerpiece around which the children play in its ubiquitous shade. For decades it’s been anchoring the neighborhood’s busiest intersection, its flourishing canopy providing coverage for both the grassy park and its adjacent streets. Few would argue… More
Introduction What are the benefits of city trees? One of the first (and most reasonable) responses is that they have a positive environmental impact: not only do mature trees sequester atmospheric carbon, but they improve air quality and assist in stormwater treatment. Trees likewise have an important economic influence, reducing energy usage by providing natural… More
Introduction As the sun blazes on another hot summer day, the thermometer on the east side of town is likely to display the same number as its counterpart three miles west — but this doesn’t tell the whole story. The way we experience heat, particularly in developed urban areas, is influenced by a number of… More
Introduction The space constraints of dense city environments present a challenge for project planners implementing an urban forestry element. There are, however, a number of solutions to help improve conditions for healthy tree growth. The Silva Cells are one such choice, a suspended-pavement system allowing for maximum soil volume. Another option is structural soil —… More
Introduction “The fighters are our salvation but the bombers alone provide the means of victory.” Winston Churchill’s words from September 1940 were prophetic, an early forecast of the indispensable role these aircraft would play in the triumph over Nazism in World War II. Dedicated to the courageous veterans of the Bomber Command, a bronze memorial… More
Introduction It’s August 12, 1884, and geologist Joseph Tyrrell — on the hunt for coal seams in Alberta’s Red Deer Valley — discovers something far different: the first dinosaur fossil ever found in the region, later named the Albertosaurus for its geographical lineage. A hundred years later, the Tyrrell Museum in Drumheller, an homage to… More
One of the chief advantages of the Silva Cell system is its ability to provide a robust soil environment for city trees — but why is this beneficial in the growth of healthy urban forests? Simply put, trees need adequate soil volume to properly grow: the more, the better. As we’ve discussed previously, roots are… More
Introduction One can’t help but feel a sense of patriotic reverence, climbing the 136 steps to the monument’s main west entrance and looking out over the U.S. Capitol across First Street — a sensation no doubt intended by Cass Gilbert and William Taft, the building’s architect and chief lobbying advocate, respectively. This is the U.S…. More
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
