Pastoralists arrived in the area in the 1880s and the area was used as a stock reserve along the Barkly stock route which was heavily trafficked up until the 1960s when road transport replaced overlanding. Cattle and fire have been excluded from the area since 1984 when the area was gazetted and fenced.[4]
