Use prescribed fire: effect on understory plants
A replicated, controlled study in 2000-2006 in temperate broadleaf forest in West Virginia, USA (Royo et al. 2010) found that prescribed fire increased understory vegetation cover and diversity. Cover (burned: 28%; unburned: 7%), species richness (burned: 2.9; unburned: 1.5 species/m2) and diversity (Shannon's index burned: 1.31; unburned: 1.06) were higher in burned plots. Eight burned (in 2001) and eight control (unburned) treatment plots (20 × 20 m) were established in each of four sites. Data were collected in 2006 in five quadrats (1 m2) in each plot.
