Management actions
Continue propagation (from seeds and cuttings) and plantings within suitable areas. Undertake targeted weed control and maintenance around known plants. Undertake revegetation/habitat restoration.

Coprosma baueri—coastal coprosma
Family RUBIACEAE

Conservation significance
Endemic to Norfolk Island and Phillip Island.
EPBC Act Listing Status: Endangered.

Description
A shrub or small tree with light green glossy leaves, small green flowers and orange egg-shaped fruit.

Distribution and abundance
Historical records suggest Coprosoma baueri may have always been rare (Gilmour & Helman 1989b). It occurs along the sea cliffs and slopes of Norfolk Island and on the higher parts of Phillip Island in cliff edge shrubland (Mills 2009b).
