Changes from 1994–2013 of (a) NMDS axis 2 scores for all upland and lowland plots, and cover values of (b) Koeleria macrantha, (c) Carex spp., and (d) Sorghastrum nutans.

Cover values were averaged for uplands and lowlands for a given burn treatment for all examples, except for Koeleria, which is shown for just uplands, since it was rarely found in lowlands.
