Chapter 7 - Advancing broad-scale forest health evaluation and monitoring with rFIAThis article is part of a larger document. View the larger document here.
The U.S. Department of Agriculture Forest Inventory and Analysis (FIA) program collects data describing the condition and change of forest ecosystems across all lands in the United States (Smith 2002, USDA Forest Service 2019b). The extraordinary size of the spatial domain and breadth of forest variables sampled by the FIA program make it a unique and powerful resource for determining the extent and severity of undesirable changes in forest health across large spatial domains in the United States. Due to a lack of flexible, userfriendly tools for estimation of forest variables (Tinkham and others 2018), the richness and utility of the FIA data are not always realized for forest health assessment. We developed rFIA (Stanke and others 2020, https://rfia.netlify. app/), an open-source R package (R Core Team 2020), to reduce these data accessibility hurdles and unlock the potential of FIA for broad-scale forest health evaluation and monitoring.
