(1) Total DEC expenditure in 2006/07 across all lands, including national parks, nature reserves, State forest and unallocated Crown land, was approximately $3.1 million for weed control and $6.7 million for feral animal control. Because programs are often integrated across land tenures, separate figures for individual categories of land are not readily available, however the total expenditure on unallocated Crown land in 2006/07 was approximately $870,000.
(2) Pest animal and weed control works have been carried out by DEC on unallocated Crown land and unmanaged reserves in the South Coast, Goldfields, Midwest, Pilbara, Kimberley, Wheatbelt, Warren and South West regions. Priorities are discussed with regional groups such as those established through the Agriculture Protection Board including zone control authorities. Significant expenditures were made on the control of wild dogs on unallocated Crown lands in the north-eastern wheatbelt and the southern rangelands, and on the control of weeds on unallocated Crown land in the Fitzroy River area and near the south coast.
(3) The success or failure of control programs is generally measured by the presence/absence or population density of the treated pest animals and weeds or by the impact of the pests on native flora, fauna and vegetation or neighbouring values.
(4) Weed eradication is extremely difficult to achieve.
