Management actions
Undertake rodent control. Carry out targeted weed control and maintenance. Undertake propagation and planting within suitable areas. Undertake revegetation/habitat restoration.

Melicytus latifolius—Norfolk Island mahoe
Family VIOLACEAE

Conservation significance
Endemic to Norfolk Island
EPBC Act Listing Status: Critically Endangered

Description
A small tree usually growing to 4m tall but sometimes reaching 9m.

Distribution and abundance
Melicytus latifolius is found in the valleys and on the slopes of the Mt Pitt section of Norfolk Island National Park, together with a few areas outside the park in the Mission Road area (Sykes & Atkinson 1988). 40 plants were identified in 1988, with a high proportion of juveniles and few seedlings or mature trees (Sykes & Atkinson 1988). Historical records suggest this plant has been rare for some time (Gilmour & Helman 1989b).
The last good flowering season was in the late 1990s/early 2000s when a large number of plants were produced in the natural forest and in the nursery plantings (Director of National Parks 2010). There were 17 known mature individuals in 2003 (TSSC 2003a). Surveys in 2012 (Mills 2012b) found a total of 16 plants along five transects, all saplings. More recently, searches have found over 100 new adults in the wild, which have been tagged for monitoring. The population estimate in 2021 was 148.
The distribution is shown in Map 45.

Ecology
Little known.

Habitat
This species requires moist shaded valley sites and
