Aerial Detection Survey Data Disclaimer:

Forest Health Protection (FHP) and its partners strive to maintain an accurate Aerial Detection Survey (ADS) Dataset, but due to the conditions under which the data are collected, FHP and its partners shall not be held responsible for missing or inaccurate data. ADS are not intended to replace more specific information. An accuracy assessment has not been done for this dataset; however, ground checks are completed in accordance with local and national guidelines Maps and data may be updated without notice. Please cite "USDA Forest Service, Forest Health Protection and its partners" as the source of this data in maps and publications.

Due to the nature of aerial surveys, the data will only provide rough estimates of location, intensity, and the resulting trend information for the agents detectable from the air. Many of the most destructive diseases are not represented because these agents are not detectable from aerial surveys. The data should only be used as a partial indicator of insect and disease activity, and should be validated on the ground for actual location and causal agent. This data shows locations where tree mortality or defoliation were apparent from the air. Intensity of damage is variable and not all trees within the areas are dead or defoliated.
