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
According to Bartlett Tree Lab’s latest newsletter, a new method of monitoring the spread of the catastrophic emerald ash borer (EAB) uses wasps.
There’s been a lot of posts lately about DeepRoot events. Sorry the normal balance of blog content is off, but it’s tradeshow season apparently. What can we say? DeepRoot will be exhibiting at the Prairie ISA show October 15 – 17 in Canmore, AB. We are in Booth 15. And in addition to exhibiting at… 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
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
There’s a great article in WaterWorld this month about Onandaga County’s comprehensive stormwater management movement, Save the Rain. The past 100 years have taken a toll on Onondaga Lake, which has given its shores and water to support industrial commerce, a regional transportation hub and urban wastewater utilities in the City of Syracuse. The factories that… More
It’s unusual — maybe unprecedented? — for us to post off of our normal Monday/Wednesday/Friday schedule, but we’ve got a lot of good articles in the queue and I didn’t want to disrupt any of those. HOWEVER. We do have a first-of-its-kind webinar coming up on October 5th that I wanted to make sure everyone… 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
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
Awhile back (actually WAY back in 2010) we discussed the how to store and how not to store Silva Cells. I thought it might be time for a little refresher on the best practices and why it is important to follow them.
Soil. Stormwater. Sustainable Infrastructure.
