Use prescribed fire: effect on understory plants Forest Conservation

A replicated, controlled study in 1946-2012 in temperate broadleaf forest in North Carolina, USA (Keyser et al. 2012) found that prescribed fire decreased the soil seed-bank species richness but not species diversity or density. Numbers of emerged species was lower after prescribed fire (before: 12.1-12.3; after: 11.0-11.3/m2), while diversity (Shannon's index in m2 1.9-2.1) and total density (419-603 emergents/m2) were similar between treatments. Five plots (5 ha) were burned in 2009-2010. Data were collected using four 0.06 m2 soil seed-bank samples, two before and two after burning, taken from each of six subplots (0.5 ha) within each plot.
