rFIA is an R package aimed at increasing the accessibility and use of the USFS Forest Inventory and Analysis (FIA) Database. Providing a user-friendly, open source toolset to easily query and analyze FIA Data, rFIA simplifies the estimation of forest variables from the FIA Database and allows all R users (experts and newcomers alike) to unlock the flexibility and potential inherent to the Enhanced FIA design.
Specifically, rFIA improves accessibility to the spatio-temporal estimation capacity of the FIA Database by producing space-time indexed summaries of forest variables within user-defined population boundaries. Direct integration with other popular R packages (e.g.,
sf) facilitates efficient space-time query and data summary, and supports common data representations and API design. The package implements design-based estimation procedures outlined by Bechtold & Patterson (2005), and has been validated against estimates and sampling errors produced by FIA’S EVALIDator.
Current development is focused on the implementation of spatially-enabled model-assisted estimators to improve point and change estimation at small spatial and temporal scales. We envision rFIA as a key component in the future of the FIA Program, targeting expansion in small area estimation, timber product monitoring, urban inventory, and the development of long-term monitoring and reporting tools.

Andy is a professor at Michigan State University with a joint appointment in the Departments of Forestry and Geography, and is a co-author of
rFIA. A central theme in his research is the use of hierarchical models to integrate information from disparate sources to improve inference and prediction. In terms of application areas, his research focuses on spatial-temporal modeling of changing ecosystem components and systems.
