#ThreatenedSpecies of the Week: Rough emu bush (Eremophila scaberula)

The Rough Emu Bush (Eremophila scaberula) is listed as Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), and Critically Endangered under the WA Wildlife Conservation Act 1950.

The Rough Emu Bush is a low-growing shrub with rough, slightly sticky branches and foliage. The branches have raised lines which extend from each leaf stalk. The crowded leaves are four to eight millimetres long and have a flat upper surface and a prominent midrib underneath. Solitary flowers emerge from the leaf axils and their pale to dark purple flower tube is about 10 to 12 millimetres long. Flowering occurs from July to November.

There are currently three populations known over a range of less than 20 kilometres. Rough Emu Bush is found on rich loam or clay flats that support open low salmon gum (Eucalyptus salmonophloia) woodland over low scrub of Scaevola spinescens, a variety of Acacia species, and grasses.

The main threats are road, rail and firebreak maintenance, weed competition, inappropriate fire regimes, lack of appropriate disturbance to stimulate germination, and degraded habitat.
