Insect and Disease Surveys (IDS) are annual aerial surveys of forests conducted by the State of Vermont and the USDA Forest Service to map forest disturbance, including damage caused by insects, diseases, fire, and weather event1. Although mortality is a natural occurrence within forests, widespread die-offs are indicative of stressors that may lead to diminished ecological function and ecosystem resilience. This metric is computed as the total area mapped with visible mortality that has occurred since the previous survey. The current year is scored as the difference between the minimum and maximum (+10%) values in the record.
