Richard examining California black walnut tree roots at Cal Expo

Richard examining the root system of a decaying California black walnut on a levee along the American River near Cal Expo in Sacramento, CA. Many governmental agencies are concerned about the impact of tree root growth on levee integrity. We were involved in a few studies to address this issue.

Richard is drilling to measure decay in the wood.

We were asked to conduct a risk assessment on a few mature trees at the American River College in Sacramento, California. Here Richard is utilizing a small drill to determine the presence/extent of decay by measuring the resistance to its penetration into the wood.
