Below: Street trees look like any others, but they are being used to test two systems designed to prevent the soil compaction that often kills street trees and at the same time provide enough space that the tree’s rooted area can retain and filter pollutants. Those being tested here are Silva cells (an open plastic framework) and structural soil (growing medium in spaces within a rock framework).
