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
