Description

A creeping to semi-scandent perennial herb up to 30cm high and spreading to 50cm diameter. Leaves (2.5-40 x 0.7-6mm) in whorls of 8+ at base and on trailing stems, the latter of which may be rooted at nodes. Inflorescences racemose and flowers pale-yellow and clustered at branch ends.


Distribution and Habitat

Restricted to three populations in FRNP with an estimated 3000 mature plants (E. Hickman pers. obs.) occurring over approximately 9km². Populations believed to be stable.

Favours in shallow gravelly soils over and among quartzite geology on slopes and summits, in heath, mallee and shrubland.
Important Populations

All three known populations are considered important to the survival of the species.


Habitat Critical to Survival

  • The area of occupancy of the known populations; and

  • Similar habitat within 1km of distribution records that provides potential habitat buffer for the species.


Biology and Ecology

Flowers Sep-Jan. Killed by fire and regenerates from soil-stored seed. Susceptibility to Phytophthora cinnamomi unknown. Juvenile period is <4 yrs.


Threats

Inappropriate fire regimes; degradation of habitat due to recreational activities; Phytophthora dieback, Climate change.

All five known populations are considered important for the long-term survival of this species.


Habitat Critical to Survival

  • The area of occupancy of the known populations; and

  • Similar habitat within 1km of distribution records that provides potential habitat buffer for the species.

  • Environment Protection & Biodiversity Conservation Act (1999): Not listed

  • Western Australian Wildlife Conservation Act (1950): Vulnerable

Photo: © Sarah Barrett (DEC)



Description

Mallee-heath dominated by Eucalyptus acies (Woolbernup Mallee), a straggly shrub or low mallee (up to 3m high) with broad, thick sub-opposite leaves, angular branchlets and rigidly down-curved inflorescences.


Distribution and Habitat

Restricted to Central Barren Ranges in FRNP, specifically Thumb Peak, Mid-Mt Barren and Woolbernup Hill.

Occurs on sandy skeletal soils on quartzite hills. Associated Declared Rare Flora species are Coopernookia georgei (Endangered), Daviesia obovata (Endangered) and Grevillea infundibularis (Vulnerable). E. acies listed as Priority 4.

Biology and Ecology

Community is highly vulnerable to infestation by the pathogen Phytophthora cinnamomi as is dominated by highly susceptible plant spp.

Also dominated by serotinous obligate seeders and therefore sensitive to frequent fire.
Threats

Inappropriate fire regimes; Phytophthora dieback, Stochastic events, Climate change.
