  1. Allow shrubland to regenerate without active management

    A before-and-after trial in 1936–1966 in a sagebrush scrub shrubland affected by fire in Idaho, USA (Harniss & Murray 1973) found that allowing shrubland to recover from disturbance without any active restoration increased biomass of big sagebrush Artemisia tridentata and decreased grass biomass after 30 years. After 30 years of recovery, biomass of big sagebrush was higher (325 kg/ha) than in the same areas immediately after fire had occurred (2 kg/ha). However, the areas’ grass biomass did not differ significantly after 30 years of recovery (164 kg/ha) from grass biomass in the same areas immediately following fire (158 kg/ha). In 1936 the shrublands were burned. Following this vegetation cover was assessed in four hundred 9.3 m2 quadrats in 1936, 1937, 1939, 1948, and 1966.
