Added: November 05, 2008Assessing new mechanical injuries present in a tree using visual, non-invasive observations is difficult and prone to wild variability, inaccuracy, and assessor subjectivity. Assessment of relative damage levels is valuable when precision allows for comparisons across one site and over many sites. Judging recent mechanical injuries from visual criteria, although imperfect, can help gauge the relative amount of damaged tissue visible and estimate the total amount of damaged tissue present.

Added: October 31, 2008Minimizing tree root growth impacts on infrastructures requires an appreciation of how roots function and generate force. To control root growth, identification of growth limiting attributes of the soil environment is necessary. Tree-literate management will control growth, protect infrastructure from root-caused problems, and protect the values and quality of trees.

Added: October 31, 2008Assessing potential risks in trees is difficult because of the complex and chaotic nature of gauging tree failures. Tree movements in the wind, and the interactions between/within tree structure and soils, assure a multitude of forces, loads, and stress concentration points will need to be a part of any tree failure model. In order to better understand tree structure and its potential failure, individual components of tree mechanics need to be isolated from the complexity. One mechanical component arising from stem and branch shape is a repeating, damped movement back and forth by the free end--commonly called "sway.''
