Condition Codes <br />An "official' and more extensive rating system for condition appraisal, published by <br />the MN Society of Arboriculture, does exist. The following is an interpretation of this <br />approach, as adapted and applied for rapid field evaluation. <br />0 = Dead or fatally diseased.NOT INVENTORIED. <br />1 = Nearly dead or in imminent threat of failure. NOT INVENTORIED. <br />2 = Heavily diseased or decayed, or with some severe structural defects. NOT <br />INVENTORIED. <br />3 = Structurally compromised, with moderate to serious defects or decay, or in <br />decline due to disease or insects. May have wildife or ecological value, but is <br />more of a laibility than an asset if a target is present. <br />4 = Structurally. sound or only small risk of potential failure, but with some defect <br />such as a wound, multiple cracks, significant lean or asymmetry (but stable root <br />plate), or showing symptoms of a non - lethal disease. <br />5 = An average tree that can be expected to live many more years; may have a <br />single crack, some minor limb damage, or dead limbs that are prunable, etc. <br />6 = Above average in form and structure, with only minor defects such as a <br />slight lean, twist or sweep. <br />7 = Noticably above average in symmetry and structure, with no apparent <br />defects. <br />8 = An exceptional tree with outstanding structure, no apparent defects and a <br />well - balanced crown and branch structure. <br />9 = A tree with exceptional structure and form, also well- pruned and maintained, <br />not normally found in natural settings. <br />10 = The ideal, perfect tree, essentially never used. <br />
