  1. Use prescribed fire: effects on mature trees

    A paired-sites study in 2003-2006 in temperate coniferous forest in Arizona and New-Mexico, USA (Breece et al. 2008) found that prescribed burns increased tree mortality. Mortality of ponderosa pine Pinus ponderosa increased from 0.6% in unburned to 8.4% in burned plots and mortality of all tree species increased from 0.6% in unburned to 9.6% in burned forest units by the end of the third growing season after burning. Trees with at least a 13 cm diameter at breast height were monitored for three growing seasons after burning (2004–2006). They were monitored in 25-40 circular plots (10 m radius within each burned (prescribed fire between 2003 and 2004) and unburned control forest units in each of four sites.
