Use prescribed fire: effects on young trees
A replicated, controlled study in 1994-2002 in temperate oak forest in Ohio, USA (Hutchinson, Sutherland & Yaussy 2005) found that two consecutive annual burnings decreased the number of small trees compared with no burning or four annual burnings; both two and four annual burnings decreased the density of saplings. The density of small trees was lower in burned×2 (130 individuals/ha) than unburned (190) and burned×4 plots (170). The density of large and small saplings was higher in unburned (600 and 1,100 respectively) than in burned×4 plots (200 and 100-250 respectively). Three treatment units (25 ha) were replicated in four sites: burned×4 (burned annually 1996-1999), burned×2 (burned in 1996 and 1999) and unburned. Data were collected in 2002 in nine plots (0.125 ha) within each treatment unit.
