Use prescribed fire: effects on young trees
A replicated, controlled study in 2002-2007 in temperate oak forest in Kentucky, USA (Alexander et al. 2008) found that prescribed fire and fire frequency had mixed effects on seedling survival depending on tree species. White oak Leucobalanus spp. seedling survival decreased to 50% in single-burn and to 40% in repeated-burn plots, compared with 70% in unburned plots. Red oaks Erythrobalanus spp. seedling survival decreased to 65% in repeated-burn compared with 75% in unburned plots. Red maple Acer rubrum seedling survival decreased to 40% in single-burn and in repeated-burn plots compared with 80% in unburned plots. Sassafras Sassafras albidum seedling survival was not affected by burning. Three study sites (200-300 ha) were subdivided into three burn treatments (58–116 ha): an unburned control, single burn (spring 2003) and repeated burning (spring 2003, 2004 and 2006). Approximately 3,000 seedlings were tagged in June 2002 and survival monitored annually from 2002 to 2007 in 8–12 plots (10 x 40 m) within each treatment.
