The BCGcalc Shiny app is a free R-based tool that calculates outputs for
Biological Condition Gradient (BCG) models (
US EPA 2016
; Figure 1). It is linked to the
BCGcalc
and
BioMonTools
R packages, which were developed by Erik W. Leppo (Erik.Leppo@tetratech.com)
from Tetra Tech and are available on GitHub.
This website was developed for biomonitoring programs in Oregon and Washington and calculates BCG model outputs for macroinvertebrate assemblages in freshwater wadeable streams in the Pacific Northwest Maritime Region (PNMR) (Figure 2). BCG model calibration is described in detail in Stamp 2022. Users can also calculate thermal preference metrics, a biodiversity index, and more. The user uploads input files to the website, which will generate the outputs without the use of R code. Those who prefer to work with R can download the R packages from the GitHub sites.

Development of the BCGcalc and BioMonTools R packages have been funded by the United States Environmental Protection Agency (EPA) Office of Office of Science and Technology (OST) (lead EPA OST scientist: Susan Jackson) and Office of Research and Development (ORD) (lead EPA ORD scientist: Britta Bierwagen).
If you encounter problems with the Shiny app and/or have suggestions on ways to further improve it, please contact Erik W. Leppo from Tetra Tech via email (Erik.Leppo@tetratech.com) or via a post on the BCGcalc GitHub Discussions page.
For more information on this project, or on the BCG in general, please contact Susan Jackson (Jackson.Susank@epa.gov).
