Dodonaea, commonly called hop-bushes, are primarily an Australian genus with 61 species identified (Jessop and Toelken, 1986). Dodonaea subglandulifera is a South Australian endemic species previously known incorrectly as D. tenuifolia (Jessop and Toelken, 1986). It is an erect, perennial shrub growing 1 to 2 m high. It has short pinnate leaves approximately 1.5 cm long with 9-17 viscous leaflets with raised glands on their lower surface (Jessop and Toelken, 1986; Jusaitis and Sorensen, 1994). The plant is dioecious and flowers between February and August. Flowers occur in groups of 2 or 3. Female plants are prominent when in fruit with capsules varying in colour from greenish-yellow to deep maroon on separate bushes. Capsules are 3- to 4-winged (Jessop and Toelken, 1986).
Dodonaea subglandulifera J.G. West is currently listed in South Australia as 'Endangered' on Schedule Seven of the National Parks and Wildlife Act 1972 (NPW Act), and also nationally Endangered on the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The species is conserved at two sites, a conservation park and a sanctuary, in the form of translocated subpopulations.
Previously, this species was only known from six sites with a total population of less than 3000 individual plants (Kahrimanis et al., 2001; Graham et al., 2001). However, information collected for this plan increased knowledge of extant occurrences to 45 sites and over 45,700 individual plants, comprising 11 subpopulations (Appendix II).
The overall objective of this Recovery Plan is to reduce the extinction risk of this species so that it is downlisted under the EPBC Act and the NPW Act from a category of endangered to one of vulnerable
