Management actions
Undertake propagation and replanting into suitable habitat areas. Conduct targeted weed control and maintenance. Implement habitat protection and rehabilitation. Monitor populations to determine dynamics.

Streblus pendulinus—Siah's backbone
Family MORACEAE

Conservation significance
Streblus pendulinus is endemic to Norfolk Island.
EPBC Act Listing Status: Endangered.
Approved Conservation Advice: 1/07/2016 (TSSC 2016c).

Description
Tree or shrub growing to 6 m tall with fleshy red fruit and very rough leaves. It exudes a white latex when damaged.

Distribution and abundance
In 1988 Streblus pendulinus was not generally common but was widespread and not considered threatened on Norfolk Island (Sykes & Atkinson 1988). The species has been recorded from Cascade Reserve, Mt Pitt, Mt Pitt Road, and about 3km north-east of the cemetery at Kingston (Orchard 1994). It was listed as Endangered in 2003, when most surviving individuals of the species were inside the Norfolk Island National Park (187 mature individuals; TSSC 2003c), Additional plants have been recorded in the Mission Road rainforest remnants, near Steels Point and in Ball Bay Reserve.
Mills (2012b) found the species on 16 transects within the national park, with 107 plants counted. All age classes were observed, and good regeneration was reported. The species also occurs in Cascade, Ball Bay and Selwyn Reserves, in small numbers (Mills 2017b, d and f).
