August Informational Webcast Scheduled

The next monthly UNRI Informational Webcast, on “Deep Roots Research“, by Gary Johnson, Ph.D., University of Minnesota, Extension Professor, is scheduled for Wednesday, August 13, 2008 at 11:00 AM (Eastern). Deep or buried root systems have been causing problems for arborists for decades. When root systems stop functioning normally, the entire tree system begins a progressive decline in health and stability.  For almost fifteen years, the University of Minnesota has been studying the effects of three types of dysfunctional root systems:  buried roots, stem girdling roots (SGRs), and pot-bound root systems.  This webcast will focus on the SGR frequency surveys, predisposition to wind storm failures, and the effectiveness of root pruning techniques.
