Management actions
Continue propagation and planting within suitable areas. Undertake targeted weed control and maintenance around existing plants. Undertake revegetation/habitat restoration. Support conservation of wedge-tailed shearwaters to promote C. baueri regeneration, as these birds help to maintain a nutrient-rich open habitat through their burrowing habit (Sykes & Atkinson 1988).

Recovery target
The recovery target is shown in Table 80.
