Plan to Protect Environmental Assets from Lantana - Weeds Australia

Plan to Protect Environmental Assets from Lantana
4.4 Objective 2: Containment lines
Objective 2 Ensure that lantana control is undertaken at and outside of
containment lines.
4.4.1 Actions 2.1 and 2.2
Action2.1
Key stakeholders will continue to promote the control of lantana at and
beyond the containment lines in northern Queensland and southern New
South Wales, and to promote lantana removal in other states.
Action2.2 National Lantana Management Group to investigate the possibility of
establishing new containment lines in strategic areas on the western
distribution of lantana in northern New South Wales and Queensland to
prevent further spread westward.
Commitment to containment lines is crucial in limiting future impacts to biodiversity. Lantana
control north of the northern containment line and south of the southern containment line is a
priority.It will also be important to maintain controlled areas and prevent recruiting plants from
seeding, and to determine the success of the program by assessing the level of recruitment
within these areas.
Performance indicator for Actions 2.1 and 2.2
The presence of lantana beyond the containment lines and in other states is kept
to a minimum throughout the duration of the five-year period of this Plan.
4.5 Objective 3: Monitor the effectiveness of lantana control programs
Objective 3
Evaluate the effectiveness of control programs at high-priority control
sites with respect to the response of environmental assets.
4.5.1 Action 3.1
Action3 .1
Key stakeholders will encourage and coordinate the monitoring of lantana
control programs at high-priority control sites.
The primary objective of this Plan is to reduce the impacts of lantana on high-priority
environmental assets. To achieve this objective, the threat of lantana will need to be reduced.
Although control programs may result in visible or obvious reductions in the density of lantana,
this may not necessarily correlate with a reduction in threat or a positive response from the
assets at risk. Therefore, it is important to undertake an evaluation of the control program(s) to
ensure success in achieving biodiversity conservation outcomes. Such evaluations must
consider:
the effectiveness of the control programs on lantana infestations (including reinfestation
rates of lantana)
the response of the priority assets to the control of lantana
the response of other environmental factors, including weeds to the removal and/or the
control of lantana.
Information on the monitoring process is outlined in Chapter 6 (also see Commonwealth of
Australia 2009) and specific monitoring protocols for native fauna will be developed in the
future.
