South Australian status: (NPW Act 1972): Endangered

Description:

Compact, sometimes straggly shrub to 1.5 m high with erect, woody, much-branched stems. Bright green leaves often held against the stems, to 2.5 mm long and 1 mm wide, sticky to the touch. Solitary, terminal daisy flowers with 2-5 white ray petals. Flowering between October and February.

Distribution:

Endemic to Kangaroo Island. Grows in low lying areas subject to seasonal waterlogging within Eucalyptus cneorifolia and Eucalyptus cosmophylla open mallee woodland. Olearia microdisca is an early successional species, with many plants found in areas regenerating from significant disturbance including fire.

Specific threats:

Threats to Olearia microdisca include vegetation clearance and loss of habitat, over-browsing by macropods (kangaroos and wallabies), inappropriate fire regimes (lack of fire), a small population size and climate change.
