Introduction: Introduced by natural means
Species Notes for this Location:
Boneseed (Chrysanthemoides monilifera ssp. monilifera) occurs along the east coast of Motutapu on coastal cliffs. This aspect faces Waiheke Island where bone-seed is abundant. Birds disperse seed from parent plants on Waiheke Island. Bone-seed rarely occurs on the west coast - a single historic record exists for Sandy Bay.
Management Notes for this Location:
The New Zealand Department of Conservation supports the Motutapu Restoration Trust's re-vegetation programme by conducting an annual survey along the entire coastline of Motutapu during the August/September flowering period and controls any boneseed discovered. Hand-removal is the chosen method of control. They are also investigating the possibility of using a biocontrol agent (Tortrix s.l. sp. "chrysanthemoides") which is currently being trialled on Waiheke Island.
Motutapu is contiguous with Rangitoto Island. The island is Crown property and managed on its behalf by the Department of Conservation. Extensive farming operations by Motutapu Farms Ltd. are ongoing together with ecosystem restoration by the Motutapu Restoration Trust (MRT). The MRT aims to restore the cultural and natural landscape of Motutapu. This includes protecting, maintaining, restoring and interpreting the cultural landscape handed down by Maori, early settler and military residents, and the ecological landscape similar to that after the Rangitoto eruption 700 years ago.

Reduction in native biodiversity: Boneseed (Chrysanthemoides monilifera monilifera) displaces native coastal species and prevents natural re-generation.
