Mulga-eucalypt line

The mulga-eucalypt line, or mulga-eucalypt boundary line, marks a boundary between Acacia-dominated shrublands and Eucalyptus-dominated open woodlands across Western Australia. It runs across the north of the Eastern Goldfields,^[1] and through the northeastern segment of Charles Darwin Reserve, from Seven Mile Well to Christmas Bore.^[2]

Its course runs along the isohyet marking 250 mm (10 in) annual rainfall.^[2]

Ferdinand von Mueller predicted its existence in 1883, and it was subsequently mapped by explorers and botanists Woodward, Diels, Clarke, Gardner, Burbidge and Beard.^[2]
