Use prescribed fire after tree planting Forest Conservation

A replicated, controlled study in 1999-2005 in Mediterranean shrubland in California, USA (Holmes et al. 2011) found that prescribed fire increased sprouting in planted valley oak Quercus lobata saplings without affecting mortality. The number of new shoots/sapling was higher in burned plots (summer burn: 4.6; spring burn: 4.6; control: 0.8), while the mortality rate was similar between treatments (summer burn: 3%; spring burn: 4%; control: 0%). Data were collected in autumn 2005 in 8-9 blocks (72 m2) of each of: a summer burn (in 2003), a spring burn (in 2004) and control treatments, with an average of ten oak trees/block.
