Five trees (#11-15)were located along the north perimeter fence line and three (#7-9)were located near the house and out buildings. gnificant structural defects that cannot be abated. 1 -Tree in severe decline, dieback of scaffold branches and/or trunk; most of foliage from epicormics; extensive structural defects that cannot be abated. 5. Rating the suitability for preservation as "high", "moderate" or"low". Suitability for preservation considers the health, age and structural condition of the tree, and its potential to remain an asset to the site for years to come. High: Trees with good health and structural stability that have the potential for longevity at the site. Moderate: Trees with somewhat declining health and/or structural defects than can be abated with treatment. The tree will require more intense management and monitoring, and may have shorter life span than those in `high'category. s, and materials? Conclusion Discussion Point#3 3.
