Threat Abatement Plan - Invasion of native plant communities by Chrysanthemoides monilifera
While some studies on the effects of herbicide on litter invertebrates were inconclusive (see
Lindsay and French 2004b), other studies showed that herbicide did have an effect on
invertebrates (Eijsackers and Van de Bund 1980).
Performance criteria for Action 7.1
< Establish a system to prioritise fauna species (or groups of species, e.g. waders) that are at risk
from bitou bush control.
< Establish sites where studies can be undertaken to determine the effects of bitou bush control
on fauna.
< Develop research projects on the effects of bitou bush control on fauna.
< Initiate these research projects during the TAP. The results of these works could then inform
subsequent Bitou TAP’s.
9.10 Objective 8: Review data and set future priorities
Objective 8 Establish guidelines for future control programs and research projects based on
the outcomes of this TAP.
9.10.1 Action 8.1 and 8.2
Action 8.1 DEC and other stakeholders will examine new data and integrate it into future
control/management strategies and best practice guidelines for bitou bush.
Action 8.2 DEC and other stakeholders will examine new data and establish future priorities for
bitou bush research.
The best practice management guides for bitou bush (see Vranjic and Groves 1999; Vranjic 2000)
and boneseed (see Adair and Ainsworth 2000) should be revised, as new information becomes
available. Also, the concept of focusing weed control on biodiversity outcomes as presented in
this TAP is a new approach in weed management (see Downey 2003a, b, submitted), and
therefore the outcomes of this TAP should determine future management and research objectives
for bitou bush and boneseed in Australia.
Performance criteria for Action 8.1
< Re-evaluated management plans and control strategies based on data collected in Actions 6.1
(fauna and bitou bush), 7.1 (fauna and control), 3.1 (decline of native plants), 2.1 (monitoring
of control programs) and 2.2 (herbicide impacts), as well as any other data available, during the
final year of the Bitou TAP.
Performance criteria for Action 8.2
< Determine future research objectives based on data collected in Actions 6.1 (fauna and bitou
bush), 7.1 (fauna and control), 3.1 (decline of native plants), 2.1 (monitoring of control
programs) and 2.2 (herbicide impacts), as well as any other data available, during the final year
of the Bitou TAP or the development of subsequent Bitou TAPs.
Note: ‘other stakeholders’ referred to in Actions 8.1 and 8.2 are those stakeholders who participate in Actions
2.2, 3.1, 6.1 and 7.1. These have not been identified at this time.
