Little Tree, Big Tree
Sure, one is on the street and one is in a park. But surely there is a better middle ground for urban trees?

In March the CBC Community Blog asked people whether cell phone towers look better when disguised as trees. The results were pretty clear – over 71 percent of people said yes.
All areas of study and their industries have to cope with inaccurate but often widely accepted mythologies, and arboriculture is no exception. There are a few of these that we encounter again and again. We’ve already busted the myth that tree roots don’t grow very deep, but here’s another one: do deep soils increase the risk… More
This post is written by Katrina Marland and originally appeared on Loose Leaf, the blog of American Forests. American Forests has had a lot to say over the years about the relationship between forests and water. From protectingsourcewater to managing overflow in cities to advocating for forests’ integration into the Clean Water Act. And of course, we’ve been planting… More
Man, those Torontonians! They continue to impress us with their aggressive green infrastructure policies. Back in January of 2010, Toronto became the first North American city to make installing green roofs on new commercial, institutional, and multifamily residential developments compulsory – now that requirements will apply to industrial developments as well.
Today we have another reprinted post from Bert Cregg, an Associate Professor in the Department of Horticulture and Department of Forestry at Michigan State University. It originally appeared on his blog, The Garden Professors. As usual, the beginning of spring is a busy time on the research side of my appointment. This past week we began setting… More
In February, the U.S. Forest Service published a report indicating that cities around the country are losing around 4 million trees per year. Of the 20 cities included in the study, 17 showed significant losses of canopy cover, and 16 showed significant increases in impervious hardscape (or paved surfaces that don’t absorb water). At the same time,… More
A combined sewer overflow (CSO) – the “the discharge of wastewater and stormwater from a combined sewer system directly into a river, stream, lake or ocean” – sounds bad enough. But have you ever seen one?
This post is by Bill Spiewak, an arborist in Santa Barbara, CA, and originally appeared on his blog, Treemendous. Last month in my arboriculture class, I may have implied to my students that this instructor is falling off the deep end. I asked them to stand and assume the yoga position, tree pose. My objective… More
Phytoremediation is the use of green plants and their associated microorganisms to stabilize or reduce inorganic and organic contamination in soils and surfacewater or groundwater. In other words, the process of using trees and other plants as biological filters. It is also a key component of what we mean when we talk about ecosystem services… More
Trees are effortlessly artful. This artfulness may be part of why they have such a calming and restorative effect on people and can elicit such powerful emotional attachment. Trees are also functional infrastructure. You can debate which role is more valuable, but from an economic standpoint, infrastructure usually wins hands-down. That’s one reason why recent… More
Last month’s Landscape Architecture Magazine had an interesting feature by Mike Singer. The article, titled “Are We Done Yet? Measuring for a project’s success is keeping clients and designers engaged well after installation,” explores an emerging trend in the field: extended contract periods to address the long-term success and performance of the site’s landscape.
Soil. Stormwater. Sustainable Infrastructure.
