TEN have successfully cleared all major infestations between the High School and Hinsby Beach. Control is ongoing however, as the seed in the soil remains viable for up to 15 years. Other boneseed plants still occur in more difficult to reach locations, such as on the Alum Cliffs and the cliffs north of the High School.

Boneseed is identified as a high priority weed in the southern region and Australia-wide is a Weed of National Significance (WONS).

At the state level, Boneseed is a declared weed, which means that in Tasmania, land managers have a legal responsibility to control it.  

Dispersal:  Seeds are spread by birds, animals and ants. Dumping of seeding plants also spreads the weed, as does infected gravel or topsoil. 

Impact:  Boneseed out-competes native vegetation. 

Control:  Seedlings can be easily hand-pulled. Seedlings can be easily distinguished from other plants by their downy-white juvenile leaves (see top photo). Larger shrubs need to be cut and pasted with herbicide immediately after cutting.

Safe alternative:  Coastal wattle (Acacia sophorae)
