Management actions
Undertake seed collection, propagation and replanting. Implement habitat protection and rehabilitation. Undertake targeted weed control and maintenance. Exclude or manage cattle grazing.

Pennantia endlicheri—pennantia
Family ICACINACEAE

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

Description
A large shrub or more usually a tree growing to 10 m tall with small white flowers.

Distribution and abundance
It was estimated that a few hundred mature trees and about 3,000 saplings were present in the Mt Pitt section of the Norfolk Island National Park in the early 2000s (Director of National Parks 2010). The species is occasionally found outside of the park (Gardner & de Lange 2002; de Lange & Murray 2003). Some large trees are also known to occur in the Mission Road remnants (Director of National Parks 2010).
The total number of mature plants recorded within the national park in 2003 was 168 (TSSC 2003c). Mills (2012b) found that this species had greatly increased its population in the national park since 2003. A total of 680 plants were counted during the study on nearly all transects and ranged from seedlings to large old trees, indicating this species is increasing in abundance and is secure.
The population estimate in 2021 was 791 individuals. Propagation and planting have occurred through the Norfolk Island National Park threatened flora program.
The distribution is shown in Map 52.

Ecology
Flowers functionally unisexual.

Habitat
This species grows in sheltered moist palm valley forest, moist upland hardwood forest and pine‑hardwood ridge forest (Invasive Species Council & TierraMar 2021). Young plants have some shade tolerance such that
