Yengo National Park, Parr State Conservation Area and

20
in Schedule 2 of the Wild Dog Control Order will be managed with the dual objectives
of managing wild dogs while at the same time conserving dingoes in core areas.
Yengo National Park and Parr State Conservation Area are listed in Schedule 2,
requiring public land managers such as the NPWS to assist in the preparation of a
local wild dog management plan in accordance with the RLP Act. Before adoption
and implementation the plans require the approval of all parties, including the NPWS.
Feral cattle, straying domestic cattle and deer are a major cause of disturbance to
native plant and animal communities. Cattle and deer cause the spread of weeds,
stream bank and waterhole erosion as well as repetitive and selective grazing of
native vegetation. They also reduce the re-colonisation of native vegetation in
previously cleared areas by grazing on young shoots.
Feral pigs occur in the Mellong Creek – Wallaby Swamp and Wallabadah areas and
cause soil disturbance when rooting for food and wallowing. Isolated small herds of
feral goat have occurred in the parks and are targeted quickly for control when
located. Goats cause significant damage as they aggressively compete with native
animals for food and habitat. Foxes prey on small mammals. The control of goats
and foxes in Brush-tailed Rock Wallaby habitat will be given priority, as these may be
a vital factor in the survival of this threatened species.
Both Blue Mountains and Central Coast–Hunter Range Regions have Pest
Management Strategies which identify introduced species of concern and provide
detailed information on methodology and control priorities.
Policies
Introduced plants and animals will be removed from the parks wherever possible;
where this is impractical control measures will be adopted.
High priority will be given to the control of introduced plant and animal species
which:
- are a risk to threatened species, critical habitat or significant plant
communities;
- are species for which current neighbouring control programs are in place or
for which threat abatement plans have been prepared;
- have a high capacity for dispersal;
- are new isolated occurrences; or
- are declared noxious.
Preference will be given to control techniques, which have minimal environmental
impact.
Control programs will be continually monitored to review their effectiveness.
The NPWS will cooperate with other agencies, such as Rural Lands Protection
Boards and local landholders, in the development and implementation of
introduced species control plans and programs.
