Knowledge gaps identified in the bitou bush threat abatement plan
A number of key knowledge gaps are identified in the threat abatement plan, for both bitou bush and boneseed.
Key research gaps for bitou bush
- The current status of bitou bush infestations in NSW, including offshore islands, should be assessed. The coastline of NSW was surveyed for bitou bush in 2001, and the results showed that the range of bitou had increased 36% in only 20 years. Another survey should be undertaken within the next 5 years to see if the extent of bitou bush is still increasing.
- The decline in native species as a result of bitou bush invasions needs further study.
- New data needs to be examined and integrated into future control and management strategies and best practice guidelines.
- The impacts of bitou bush invasion on fauna need further study.
- The effects of herbicide on priority species, and other native species, need to be studied.
- The impacts of controlling bitou bush in sites that have been invaded for a long time need to be studied.
- Future priorities for bitou bush research need to be set.
Current research for bitou bush
Research currently undertaken by the University of Wollongong is also working to address these knowledge gaps. Their latest research on the impact of bitou bush on native communities can be found at

Key research gaps for boneseed
- A detailed survey is required to determine the distribution of boneseed in NSW.
- The seed longevity of boneseed needs to be studied before an effective containment or eradication strategy can be developed.
- A containment or eradication strategy should be developed for boneseed in NSW.
