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
According to Bartlett Tree Lab’s latest newsletter, a new method of monitoring the spread of the catastrophic emerald ash borer (EAB) uses wasps.
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
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.
