Management actions
Undertake propagation and planting within suitable areas, including public reserves. Implement habitat protection and rehabilitation. Carry out ongoing targeted weed control and maintenance. Exclude or manage cattle grazing.

Meryta angustifolia—Narrow-leaved Meryta
Family ARALIACEAE

Conservation significance
Endemic to Norfolk Island.
EPBC Act Listing Status: Vulnerable.

Description
Tree growing to 6m tall with few branches.

Distribution and abundance
There were 479 mature individuals of Meryta angustifolia recorded on Norfolk Island in 2003 (TSSC 2003b). Orchard (1994) reported that the species was widespread within the Norfolk Island National Park (particularly in areas where weed control had been carried out) and recorded it from the northern and southern
