CONDITION RATING
Rating | Description | General Criteria |
1 | Excellent | The tree is typical of the species, has less than 10 percent deadwood in the crown that is attributable to normal causes, has no other observed problems, and requires no remedial action. |
2 | Good | The tree is typical of the species and/or has less than 20 percent deadwood in the crown, only 1 or 2 minor problems that are easily corrected with normal care. |
3 | Fair | The tree is typical of the species and/or has less than 30 percent deadwood in the crown, 1 or 2 minor problems that are not imminently lethal to the tree and no significant decay or structural problems, but the tree must have remedial care above normal care in order to minimize the impact of future stress and to ensure continued health. |
4 | Fair to poor | The tree is not typical of the species and/or has significant problems such as 30 to 50 percent deadwood in the crown, serious decay or structural defect, insects, disease or other problems that can be imminently lethal to the tree or create a hazardous tree if not corrected in a short period of time or if the tree is subjected to additional stress. |
5 | Poor | The tree is not typical of the species and/or has over 50 percent deadwood in the crown, major decay or structural problems, is hazardous or is severely involved with insects, disease, or other problems that even if aggressively corrected would not result in the long term survival of the tree. |
6 | Dead | Less than 10 percent of the tree shows signs of life. |
