The locations of first detection and county-level occurrence for 101 major non-native pests (n = 84 insects, 17 pathogens) of trees were compiled for the contiguous USA. Data were originally collected for the Alien Forest Pest Explorer database.1 Briefly, locations (latitude, longitude) of discovery and occurrence at the county-level were compiled from primary literature articles, surveys, and federal and state government reports. For each pest, we obtained the year of first discovery, global region of origin or simply “origin” (Asian Palearctic, Australasia, European plus Asian Palearctic, European Palearctic, or Neotropic Mexico/Central/South America; based on a pest’s native range), and guild (bark/wood-borer, foliage-feeder, sap-feeder, pathogen).
