The U.S. Forest Service Forest Inventory and Analysis Program uses visual inspections of trees from bottom to top to record damage that is likely to prevent survival, reduce growth, or hinder capability to produce marketable products. This report describes the types of damage and occurrence as measured across the 24-state northern region between 2009 and 2013. Descriptive statistics and spatial occurrence maps are presented by genus, species, and state. Inter- and intra-species variation, as well as biotic and abiotic disturbance agents, are issues that should be considered while analyzing and interpreting data from damage indicators.
