Use prescribed fire: effects on mature trees
A replicated, controlled study in 2001-2009 in temperate coniferous forest in California, USA (Van Mantgem et al. 2011) found that prescribed burning increased tree mortality in the short-term but not in the long-term. Tree mortality rate was higher in burned plots in the first six years after treatment (unburned: 1.5% in all six years; burned: 47% in the first to 3% in the sixth year), but similar in the following two years (unburned: 1.5%; burned: 1.5-2.0%). Data were collected in 2001-2009 in five burned (prescribed-fire in 2001) and seven unburned control plots (0.9-2.5 ha).
