Effects of root system configuration and partial excavation on tree stability

2010 | Stephen Mitchell, University of British Columbia
In order to assess the behavior of tree root-soil systems with different root configurations, different root-soil volumes, and varying levels of damage we will: 1) instrument tree stems and root systems and monitor deflection and resistance under dynamic loading, and then under progressively increasing static loading up to failure; 2) document root configuration and soil properties for failed trees; 3) use this information to calibrate and validate numerical finite element simulations of root-soil system behavior under load; 4) use these models to explore the implications of root configuration and material properties, and soil properties for mechanical configuration; 5) explore the implications of root pruning, disease or constrained root systems for tree stability; and, 6) develop tools and standards for arborists to use in assessing the root/soil component of tree stability.
