For the last two weeks of December I’ll be reprinting some of our favorite blog posts instead of putting up new ones. These will be on those evergreen topics that we can always revisit and apply to current projects. As this year winds down, hopefully some of these will be helpful as you plan for… More

Remember how exciting it was to use a microscope for the first time? I remember looking at our own hair in fifth grade (I went to a hippy dippy school where we could design many of our own experiments, and we were obsessed with the idea of conditioner causing “buildup,” which, is that even really… More
While green roofs have been used for the past 30-40 years in Europe, the spread of green roof technology in North America is much more recent. Need for low impact stormwater management techniques is one of the biggest drivers for green roof technology in North America.
Sometimes, in order to bring new understanding to an issue and cut through the meaningful-but-sometimes-numbing-data, you need to reframe it. There are so many ways that big trees enhance life for people and other living things: air quality, safety, water quality, lower temperatures. These cross environmental, development, and design boundaries. All are fundamentally public health… More
In part 1 of this series, I summarized some of the lessons we learned from those people on the forefront of setting minimum soil volume policies. In today’s article, I will summarize how actual adopted soil volume policies compare to the minimum soil volumes trees need according to research studies.
Trees need an adequate volume of rootable, oxygen-rich soil to thrive, and minimum soil volume policies are a powerful tool for arborists and other advocates to leverage better growing conditions for trees, especially in urban areas. In preparation for Peter MacDonagh’s presentation at the 2012 ISA conference in Portland, OR, “Leveraging Healthy Urban Forests with… More
I am finding out about this many years too late, but from 2008 to 2010 the Smithsonian Museum of Natural History had an exhibit called Dig It! The Secrets of Soil. Fortunately for me, a version of the exhibit still lives on online.
This video from Tree People reminds me a little bit of Annie Leonard’s “The Story of Stuff,” except it’s about the role of trees in green infrastructure.
We like to keep track of cities that are doing more for trees, specifically by implementing minimum soil volumes for urban planting. I’m happy to share that we are adding the city of Oakville, ON to the list, where they have recently implemented a requirement that street trees be planted in 30 m3 (1,059 ft3) of soil… More
I’ve been reading Chip & Dan Heath’s Made to Stick, a book about why some ideas succeed and others fail. It’s fascinating. It’s also very, very funny. And it’s made me think a lot about how we communicate about green infrastructure and the importance of trees, soil and stormwater in our cities and towns. Fundamentally, everyone’s… More
Soil. Stormwater. Sustainable Infrastructure.
