Management actions
Continue targeted weed control and maintenance around existing plants. Undertake revegetation/habitat restoration. Continue to exclude grazing.

Cordyline obtecta—Ti
Family AGAVACEAE

Conservation significance
Found only on Norfolk Island and in New Zealand.
EPBC Act Listing Status: Vulnerable.

Description
An erect shrub or tree to 10m tall with an erect pyramidal flower spike about 30cm long, grey bark, and whitish or blue-purple fruit.

Distribution and abundance
There were 818 mature individuals on Norfolk Island in 2003 (TSSC 2003b), with 65% of the population occurring within the Norfolk Island National Park. The population greatly improved over the next decade (Director of National Parks 2010) and had increased to 1863 individuals in 2021.
This species propagates well and has been planted in several public areas. On Phillip Island, it has been planted in the upper part of Long Valley (Mills 2009b). Abundant regeneration may take place following woody weed removal in the Mt Pitt section of the national park. The species has been planted
