Data collected during the resurvey of ice storm-damaged trees in 2004.
| Variable | Comments |
|---|---|
| Status | Whether the tree was found or removed |
| Diameter at 13.7 m | Measured using a diameter tape |
| Condition | Subjective estimate of overall tree condition based on a categorical ranking on a 1 to 4 scale with 4 = good, 3 = fair, 2 = poor, and 1 = dead |
| Dead small | The number of small-sized dead branches in the crown that were 2 to 4 in in diameter, branches estimated at 6 in from the point of attachment |
| Dead medium | The number of medium-sized dead branches in the crown that were 4 to 6 in in diameter, branches measured at 6 in from the point of attachment |
| Dead large | The number of small dead branches in the crown that were greater than 6 in in diameter, branches measured at 6 in from the point of attachment |
| Hazard small | Defective branches (excluding dead branches) that were 2 to 4 in in diameter measured at 6 in from the point of attachment that had developed as a result of the ice storm damage |
| Hazard medium | Defective branches (excluding dead branches) that were 4 to 6 in in diameter measured at 6 in from the point of attachment that had developed as a result of the ice storm damage |
| Hazard large | Defective branches (excluding dead branches) that were greater than 6 in in diameter measured at 6 in from the point of attachment that had developed as a result of the ice storm damage |
| Sprouts per pruning wound | The average number of epicormic sprouts from ice storm origin pruning wounds; the wounds had to be greater than 4 in in diameter |
| Sprouts per ripped branch | The average number of epicormic sprouts from ice storm origin ripped branches (branches that were broken but not pruned after the ice storm); the branches had to be greater than 4 in in diameter |
| Wound decay percentage | Percent of pruning wounds with an observable cavity from decay |
| Wound closure | Average amount of woundwood in inches on the edge of pruning wounds that were greater than 4 in in diameter |
| Crown loss | The amount of crown missing in 5% categories in comparison to a full crown (full crown less any loss resulting from shading, utility pruning, crown raising, or previous ice storm damage) |
| Dieback | Estimated amount of the total crown in 5% categories showing branch dieback or death in 5% categories. |
| Crown density | Estimated amount of light blocked by the crown of the tree compared with standardized crown density charts (FIA 2006) in which 100% means no light is coming through the crown |
