- 10. Weeds Reviewed African olive African lovegrass Bitou bush Black berry Boneseed Camphor laurel Chilean needle-grass Coolatai grass Lantana Large & small-leaved privet Phalaris South African pigeon grass Scotch broom Serrated tussock
- 11. Targeted agency review NSW Department of Primary Industries NSW National Parks & Wildlife Service
- 12. Key Findings and Management Options Bitou Bush and Boneseed Fire of at least moderate intensity can be used to kill mature and young plants. This allows access to dense areas for future control and kills seeds in the soil seed bank and triggers mass germination which can be killed by a followup burn or other control techniques (Brougham, Cherry & Downey 2006) Follow-up control of emerging seeds may be required for at least 10 years Having the capacity to adaptively respond to unplanned wildfire events can, in many instances, also assist in achieving good restoration outcomes.
- 13. Bitou bush – recently treated Burnt seven months ago – stimulation of soil seed bank
- 14. Lantana The many interactions of fire and lantana can often be a “double-edged sword” and a process that will require cautious and thoughtful management to avoid exacerbating the degrading influence of this transformer weed. In landscapes supporting ecosystems adapted to a relatively high fire frequency there is good potential for the use of fire to prevent the establishment of lantana recruits and to limit its spread at the landscape scale’
- 16. Coolatai grass (Hyparrhenia hirta) and Scotch broom (Cytisus scoparius subsp. scoparius), Fire was found to substantially contribute to the establishment of or promote existing infestations. Fire should be excluded from infestations unless substantial resources over many years to follow up are available
- 17. The review provides a foundation from which land managers and landholders can discuss, plan and implement the best management responses to weeds, and this is being incorporated as a core component of Hotspots workshops across NSW.
- 18. Should we be investing public funds in restoring landscapes that will be inundated by rising sea levels in the coming decades?
