Allow shrubland to regenerate without active management Shrubland and Heathland Conservation

A replicated, before-and-after trial in 1993–1998 in 90 sage scrub and chaparral shrubland sites that had been burned by wildfire in California, USA (Keeley et al. 2005) found that allowing shrublands to recover without active restoration increased shrub cover. After five years of recovery, shrub cover was higher (45–92%) than it had been immediately after wildfires (4–15%). Sites were 0.1 ha areas where wildfires had burned in the previous year. At each site twenty 1 m2 quadrats were used to estimate plant cover and density.
