Management action
Implement targeted weed control and maintenance around host trees. Implement habitat protection and rehabilitation. Monitor/survey likely areas of the national park after storms, rescue any fallen specimens and attempt to cultivate them in at the Norfolk Island National Park Nursery (Sykes & Atkinson 1988).

Recovery target
The recovery target is shown in Table 148.

Ungeria floribunda—bastard oak
Family STERCULIACEAE

Conservation significance
Endemic monotypic genus which could be one of Norfolk Island's most ancient plants.
EPBC Act Listing Status: Vulnerable.

Description
A tree growing to 15 m tall with deep pink flowers.

Distribution and abundance
Ungeria floribunda is evenly distributed through the Norfolk Island National Park. It occurs on the broad ridges and upper valley sides and is also found on flat sites outside the park in the north-west part of the island. Young trees are associated with secondary forest that has established following removal of the original canopy.
The total number of mature plants recorded in 2003 was 502 (TSSC 2003b).
Regeneration is restricted by predation of seeds by rats (either on the tree or on the ground) and because
