The Northeastern Forest Health Atlas (NEFHA, https://www.uvm.edu/femc/forest-health-atlas) provides an online, searchable interface for assessing decades of forest disturbance monitoring and research data in maps, tables and charts. Prior to this effort, obtaining data on forest disturbance was difficult, and comparing it across years and programs was even harder. The objectives of NEFHA are to improve access to standardized data related to forest disturbance across both space and time for forest managers and researchers. The atlas is hosted and maintained by the Forest Ecosystem Monitoring Cooperative (FEMC), and was developed with funds provided by the Northeastern States Research Cooperative (NSRC). In this report, we describe the history of the effort, technical details about how we compiled data, and summaries of major aspects of the resulting dataset. The NEFHA unifies monitoring and research data from two major sources. First, we compiled spatial disturbance data collected by individual states and the US Forest Service through aerial detection surveys. These annual aerial surveys have been conducted for decades to identify and map the locations of biotic and abiotic forest disturbances. The second source of data for NEFHA are research outputs derived from studies funded by NSRC. Since it began, NSRC has funded hundreds of studies examining forested ecosystems in the Northern Forest to better understand how these resources are changing, and how these changes may affect the people that depend on them. NEFHA provides access to aerial detection survey and other insect survey data consisting of 106,966,940 hectares (ha) of disturbance mapped on 100,243 polygons attributed to 222 damagecausing agents. The data go back in time as far as 1918 in Maine, and all states have consistent coverage from 1997 to 2016. Region-wide, the most damage has been attributed to spruce budworm (78,598,995 ha), followed by forest tent caterpillar (11,152,081 ha), gypsy moth (4,550,215 ha), and balsam woolly adelgid (3,147,304 ha). NEFHA also provides access to research projects and, in some cases, associated data and publications funded by the NSRC. In total, we created archive pages for 30 projects related to forest health and disturbance, 11 of which provided data. The FEMC will maintain the NEFHA into the future. FEMC will ingest and integrate new disturbance data with the existing regional data in the NEFHA, advise and support states in digitizing additional historical disturbance data when possible, and expand the research data holdings by incorporating additional studies in NEFHA that were not originally funded by NSRC. The tools and data access mechanisms in NEFHA provide a novel and invaluable tool for quickly finding and mapping data on forest disturbance in the northeastern US. This resource will continue to grow in volume and relevance as a changing climate, shifting land use, and new stressors continue to spur change in forests.
