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
According to Bartlett Tree Lab’s latest newsletter, a new method of monitoring the spread of the catastrophic emerald ash borer (EAB) uses wasps.
In 2011, CMG Landscape Architecture was approached by a tech company to design the courtyard of their new headquarters in Menlo Park, CA. The project was on a very fast track. In addition to the accelerated timeline, CMG’s proposed design for the site had the total impervious surface area increasing from 40 percent to 60… More
Today we welcome back regular blog contributor Ellyn Shea, talking more about my favorite tool when walking around the streets of San Francisco. -LM Back in July, I related the history of an educational website called the Urban Tree Key that helps urban citizens without botanical training identify trees in their community. As promised, here… More
I was privileged to hear Dr. Philip Mote speak at last month’s International Society of Arboriculture conference in Portland, Oregon on climate change. Among other things, Dr. Mote is a professor in the College of Oceanic and Atmospheric Sciences at Oregon State University. He is not an arborist, but he translated the complexities of climate science… More
Okay, we know you have done a lot of work. You have analyzed your site and have picked the best tree species for your area, provided the trees with the optimal volume of planting soil, selected the best specimen from the nursery, and made sure it has arrived on-site in great condition. We think what… 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.
Today’s guest post is from Nathalie Shanstrom, a sustainable landscape architect with the Kestrel Design Group. It’s a little science-y, but still very readable. If you’re not a stormwater geek, don’t be deterred – there’s a lot of great information in here. -LM Parts 1 and 2 of this blog series looked at how plants… More
This is interesting – two studies I’ve read recently emphasize the very real value that the urban forest has for migrating birds.

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.
Soil. Stormwater. Sustainable Infrastructure.
