  • A. Study area. The shaded area corresponds to the counties within Mississippi (MS) and Alabama (AL), USA that comprised the Black Belt region during the 1830s (Barone 2005). The black dot corresponds to the Black Prairie Wildlife Management Area (33°34’ N, 88°58’ W) where this study took place. B. Block (90x70 m) formed by three randomly assigned plots. C. Plot (70x30 m). Each plot corresponded to a different treatment (spring burn, summer burn, and unburned). D. 1-m2 quadrat. Each plot was sampled using ten 1-m2 quadrats separated by at least five meters.

  • Non-metric multidimensional scaling (NMDS) ordination of sampling units (plots), based on Bray-Curtis dissimilarities of percent plant cover at each sampling time.

  • Mean response of plants categorized by their native status and growth forms to the different burn treatments at each sampling time. Graminoids were further divided into two categories based on their photosynthetic pathway (C3 vs. C4). Error bars represent standard errors (SE). Note variation in Y-axes among rows.

  • Mean response of diversity metrics (species richness, exponential of Shannon-Wiener index, and inverse Simpson index) to the different burn treatments at each sampling time. The three diversity metrics are in units of species richness at the 1-m2 quadrat level. Error bars represent standard errors (SE).
