Burning season does not affect post-fire regeneration but fire alters the balance of the dominant species in a seeder-dominated Mediterranean shrubland

Allow shrubland to regenerate without active management
A replicated, randomized, controlled, before-and-after trial in a shrubland in southern Spain (Cespedes et al. 2014) found that allowing shrubland to recover from fire without any active restoration increased cover of woody plants but reduced cover of herb species after three years. Three years after fire, cover of woody species was higher (67%) than one year after fire (21%) and was not significantly different from cover before fire occurred (75%) or cover in unburnt plots (73%). The cover of herb species was lower three years after fire (18%) than one year after fire (54%), but cover was not significantly different to unburnt plots (14%). Twelve 625 m2 plots were established and randomly assigned to be burned, or left unburnt. Before burning and for three years afterwards twenty 1 m2 quadrats per plot were used to assess cover of plant species. Seedling density was assessed using 25 cm x 25 cm quadrats.
