Senecio hooglandii—a daisy
Family ASTERACEAE

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

Description
An erect herb growing to 60 cm tall with yellow daisy flowers.

Distribution and abundance
Senecio hooglandii has been recorded from near the cemetery on Norfolk Island and on the north side of Phillip Island, though its occurrence on Phillip Island may be due to the widespread broadcasting of seed to revegetate the island following rabbit removal (Orchard 1994).
There were fewer than 550 mature plants recorded in 2003 (TSSC 2003b). The species is moderately common around the cliffs of Phillip Island (Mills 2009b) and also occurs on Nepean Island (Mills 2009a).
The distribution is shown in Map 61.

Ecology
Little known.

Habitat
Little known.

Threats
The primary threat to the species is weed invasion and competition, particularly by kikuyu (Cenchrus clandestinus).

Impact on other species
None known.
