Species diversity


We used rFIA to estimate average species diversity indicies for live trees ($DBH >= 12.7 cm$) at alpha, beta, and gamma levels, with associated sampling errors, within ecoregion subsections which surround the Appalachian National Scenic Trail. We produced estimates for each FIA reporting year which was common among all states included in the analysis (2005-2016, with the exception of 2008).
