Plot 1 from Prevey et al 2024

A Locations of all plots in the dataset. Brown points indicate plots that burned up to 50 years prior to vegetation measurements (n = 26,729), and green points indicate plots that were not identified as having burned within 50 years of measurements (n = 211,070). The size of points relates to the percent foliar cover of non-native plant species recorded at that plot. B Average cover of all non-native plant species in plots burned up to 50 years prior to measurement, and unburned plots, ± standard error. Map tiles for base map by Stamen Design, under CC BY 4.0.
