Data A1 Species Richness Data

Data S1. Raw data from over 276 plant species that were collected along a 48.28-km stretch of roadside right-of-ways in northeastern Mississippi from 2010 to 2012. The data are categorized by years (2010, 2011, and 2012), seasons (fall, spring), elevation (upland, lowland), site location number (1, 2, 3, 4, and 5), and by TRT (treatment; mow, no-mow, and seed). These categories are summarized with NativeSR (native species richness), NonNativeSR (nonnative species richness), UnknownSR (unknown genus), and Total SR (total species richness count)
