Factors that influence suitab+lity include: <br /> He�lth: Overall tree vigar, extensior� of new growth, proper closing of wounds and the <br /> presence of plant pathogens. <br /> tructur : The overall tree architrave, including roots, trunk, limbs, and branches are <br /> visually assessed for defects. A defect that can be corrected by proper arboricultural <br /> practices may allow a tree to be �reserved. <br /> Saf and iJseful Life Ex ctanc : The life of a tree is much like a bell-shaped cunre; <br /> where aging accentuates tree vigor until a }�oint at the top of the curve where aging <br /> now reduces tree vigor and decline begins. A species may be lang lived but have a <br /> poor structure that is prone to fail (e.g. blue gum) and should not be considered safe or <br /> useful. <br /> Tree Species: The factors described above are predicated on the tree species. Certain <br /> spec+es grow slowly and decline slowly {e,g, coast live oak). Other species grow quickly <br /> and decline quickly (e.g. Manterey pine). Tree species that are invasive. or a nuisance or <br /> have an inherently poor structure are to be avoided (e.g. Bailey acacia}. <br /> Sultabllity itatings <br /> When the above factors are considered, assessed trees were rated as H1GH, MODERA�E <br /> or LOW in suitability for preservation. An explanation for each rating is provided below. <br /> HfG�I: Trees which are significant and expECted ta provide long-term contributions to the <br /> site. 7hey display fair or better health and fair or better structural candition. On-going <br /> suitability may require typical maintenance practices commonfy associated with the tree <br /> species. These trees are the most suitable far retention measures and are worthy of <br /> consideration during the design process or de5ign revision. <br /> MODERATE: Trees which contribute to the site but provide less than significant <br /> contributions for reasons of health, 5tructura! condition or appearance. On-going <br /> suitability will require praperly implemented maintenance practices. Design revisions to <br /> preserve these trees may not be warranted. <br /> LOW: Trees which provide minor contributians to the property for reasons of poor health, <br /> structural condition or appearance. A tree species tl�at is a nuisance due to litter,will <br /> grow toa iarge for the area or is known to develop a structure prone to failure is also <br /> rated low in suitability. Generally speaking, trees in this category are not expected to <br /> l�enefit or respond to acceptable corrective measures. Removal of these trees wili o�ten <br /> alfow the safe, useful and aesthetic enjoyment of the property. Preservafion of!ow rated <br /> trees is not recomme�ded. <br /> .�����"�'�.��;rP����8�,����'��'�"���'�����._omdP,Mw �P��;:1�1��'. �°�d°�P�i�" ;a"� <br />
