Allow shrubland to regenerate without active management
A before-and-after trial in 1991–1994 in a heathland that had previously been burnt by wildfire in southern Spain (Ojeda et al. 1996) found that allowing recovery without active restoration increased the number of seedlings of common heather Calluna vulgaris, but not of rock rose Cistus populifolius and Genista triacanthos. After three years of recovery, the number of seedlings of heather (29 seedlings/m2) was higher than found in the first year after fire (0 seedlings/m2). However, the numbers of rock rose (7 seedlings/m2), and Genista triacanthos (7 seedlings/m2) seedlings was not higher after three years than in the first year after fire (rock rose: 8 seedlings/m2, Genista triacanthos: 6 seedlings/m2). A wildfire occurred in 1991. The abundance of seedlings was recorded annually in 50 randomly located 1 m2 quadrats in 1992–1994.
