Back in December 2012, we reported the first preliminary results of Stormwater Treatment Performance Monitoring by Dr. William Hunt, Jonathan Page, and Ryan Winston, of two Silva Cell Systems in Wilmington, North Carolina. Final results and statistics are expected later this summer. In the meantime, preliminary results are so promising that we want to share… More
We are often asked for research results documenting the measurable benefits of using Silva Cells to manage stormwater on site, so we are thrilled to announce that two Silva Cell systems were installed for this purpose during the summer of 2012 in Wilmington, NC. They are being monitored by an excellent research team at Dr…. More
Here is this year’s photos from the Bartlett Tree Lab study comparing different planting methods for urban trees. For comparison, check out last year’s set. And for a fuller chronological picture, you can see each year’s photos, from 2004 onward, here.
Research to date has shown that bioretention can be effective for water quality treatment and for preserving the pre-development hydrologic function of a site, but what happens when air temperatures dip below freezing? Studies indicates that with proper design and maintenance, bioretention can function well even in cold climates.
Here are this year’s photos from the Bartlett Tree Lab study comparing different planting methods for urban trees. For comparison, check out last year’s set. And for a fuller chronological picture, you can see all the photos up to that point in this post.
By Albert Key While there is much empirical information on wind throw, ultimately, we do not know the exact stresses which wind puts on mature trees, as the only way to academically test wind throw is with young trees. A study that I worked on with Dr. Tom Smiley of the Bartlett Tree Laboratory generated… More
Last we checked, the trees in suspended pavement at the Bartlett Tree Lab were doing awesome at 5.5 years. Growing season 6 photos are in and they still look great! (Structural Soil twig on the left, Suspended Pavement twig on the right).
In areas where it snows and freezes, salting is a frustrating reality of the road. Salt used for melting ice on pavements in northern climates is quite harmful to trees and soil. The most common and least expensive form of ice melting salt is sodium chloride, which is the same salt we put on our… More
When we were first researching and designing the Silva Cell, Tom Smiley, PhD set up a research plot* at the independent Bartlett Tree Laboratory in Charlotte, NC. We were confident about the design principles used in the construction of the Silva Cell, but also wanted to measure exactly how it held up against competitive products… More
