After a big windstorm, we who work with and love trees take note of the damage with trepidation. Large trees that have split apart or lost a major part of their structure often cannot be saved and must be removed. Fortunately tomorrow’s urban forest has a better chance – if we act today!
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
A few weeks ago I went to the exhibit Do Not Destroy: Trees, Art, and Jewish Thought at the Contemporary Jewish Museum here in San Francisco. The title of the exhibit is taken from a commandment in the Torah that forbids the “wanton destruction of trees during wartime.” Later, this concept was expanded to the responsibility to… More
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
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
At DeepRoot we like to keep it fresh and fun for everyone. And what is more fresh and fun than innovating our products to be more field efficient and environmentally friendly as well as meeting market demands? (OK, so I work in Operations – sue me). To that end, we’ve got some pretty awesome product… 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.
Soil. Stormwater. Sustainable Infrastructure.
