Abstract

Eremophila gilesii, a woody pioneer species, is very responsive to disturbance in the mulga communities of south-western Queensland. Under present management it is increasing in density. The ability of the plant to invade areas cleared of mulga trees is demonstrated. Ploughing out stands of E. gilesii, slashing at ground level, and applying any one of many common herbicides as a high-volume foliar spray were effective methods of killing the plant. A 1% a.i. 2,4,5-T ester-diesel distillate combination was particularly effective. The plant is periodically attacked by a wingless grasshopper (Monistria pustulifera), and when insect populations are high, large areas of E. gilesii are killed. The feasibility o!f applying a previously hypothesized grazing management technique to prevent future regeneration of E. gilesii from seed is demonstrated.
