Scientific name: Beyeria subtecta

Common name: Kangaroo Island Turpentine Bush

The Kangaroo Island Turpentine Bush is a small, rigid and very sticky (Black 1922; Jessop & Toelken 1986; Leigh et al. 1984) shrub, growing to 60 cm in height (Barker & Dashorst 1984; Davies 1986). The flowers are white (Barker & Dashorst 1984) or yellowish (Leigh et al. 1984). Plants are dioecious (Barker & Dashorst 1984).

The Kangaroo Island Turpentine Bush is endemic to Kangaroo Island, and is known from a strip of land 5 km on either side of Hog Bay Road. This road is between Min Oil Road and Three Chain Road, on eastern Kangaroo Island (Taylor 2008).

Before 2000, the species was known to occur in 84 localities over a small range (Davies 1986, 1992, 1996). Eighty of these localities occurred on roadsides, three were conserved and one was adjacent to a rubbish dump (Briggs & Leigh 1996; Davies 1986). The roadside localities ranged in size from one plant to 282 plants (Davies 1996). The largest populations were not on road verges and comprised several thousand individuals. One population was in the York Farm Scrub, which is protected under a heritage agreement (Davies 1986; RNEDB 2001). The York Farm Scrub is the largest remnant of the Kangaroo Island Narrow-leaf Mallee (Eucalyptus cneorifolia) open scrub. A second population was known within the Beyeria Conservation Park. The plants in the Beyeria Conservation Park occurred within open heath (RNEDB 2001). A third population occurred over 25 ha of private property, unprotected from grazing stock in 1992 (Davies 1992), and was subsequently protected under a heritage agreement (Briggs & Leigh 1996).

A further population containing a few dozen individuals occurred on the edge of a stone reserve, which was developed as a council rubbish dump in 1986 (Davies 1986).

Historically, the Kangaroo Island Turpentine Bush was known only from the type collection made in the early 1900s from Cygnet (Black 1922; Leigh et al. 1984), and two collections in the 1960s west of American River (Leigh et al. 1984), until it was relocated in the early 1980s (Jackson pers. comm. cited in Leigh et al. 1984). The species is likely to have been lost from the type locality (Leigh et al. 1984). The species is likely to have occurred on upper slope and plateau areas adjoining the existing sub-populations (Taylor 2008).

Details of surviving populations are stored as a computerised database at the Information Systems Branch of the South Australian Department of Environment and Planning (Davies 1986).

There are two important known sub-populations of Kangaroo Island Turpentine Bush (Taylor 2008):

Sub-population Location Number of plants Area of occupancy (km²)
A Hog Bay Road (Rd), Willsons Rd, Beyeria Conservation Park (CP), Halls Rd and Redbanks Rd 10829 30.4
B Moores Rd, Three Chain Rd, Boundary Rd, American River Rd, Flour Cask Bay Rd and Hog Bay Rd 317 21.2
  Total 11146 51.6

The Kangaroo Island Turpentine Bush occurs on gentle upper slopes associated with the highest sections of the Haines Plateau and Eastern Plains of eastern Kangaroo Island. The species grows on sand and loamy sand (varying from dark brown to light yellow brown in colour) with a pH of 6–7 (Davies 1986; Taylor 2008). The annual rainfall, at known locations of the species, range from 485 mm (at Kingscote) to 529 mm (at American River), and mean annual minimum and maximum temperatures (at Kingscote) are 11.5 °C and 19.0 °C respectively.

The species is usually found in open scrub, tall shrubland or regenerating areas of mallee scrub, closed heath and Kangaroo Island Narrow-leaf Mallee – Broombrush (Melaleuca uncinata) associations. The overstorey is usually dominated by Kangaroo Island Narrow-leaf Mallee. Understorey species of this plant community include Holly Grevillea (Grevillea ilicifolia), Sticky Swordsedge (Lepidosperma viscidum), Slender Honey Myrtle (Melaleuca gibbosa), Broombrush, Micrantheum demissum, Rough Fan Flower (Scaevola linearis) and Centenary Starburst (Thryptomene ericaea) (Barker & Dashorst 1984; Davies 1986; Taylor 2008).

The Kangaroo Island Turpentine Bush flowers between June and February (Davies 1986; Jessop & Toelken 1986).

Currently, all subpopulations of the Kangaroo Island Turpentine Bush are threatened by small scale vegetation clearance activities, weeds (specifically Bridal Creeper (Asparagus asparagoides), Perennial Veldt Grass (Erharta calycina) and Phalaris (Phalaris aquatica)), soil salinity and trampling. Due to their highly fragmented population, all subpopulations are also potentially threatened by edge effects. Subpopulation A (which accounts for 97% of the total population) is threatened by herbivore grazing and erosion. Phytophthora spp. infestation is an issue at subpopulation B (which is 3% of total population), and this subpopulation is also potentially under threat from declining genetic viability due to its small size (less than 1000 plants) (Taylor 2008).

In 1984, undisturbed native roadside vegetation containing Kangaroo Island Turpentine Bush was cleared. In 1985, an exemption in the Native Vegetation Management Act 1985, allowed an area of regenerating vegetation containing the species to be legally destroyed. A very small population on the edge of a regenerating patch of native vegetation was also ploughed (Davies 1986). Any remaining plants near American River are likely to be at risk from further clearing for farming, by roadwork and weed invasion (Leigh et al. 1984).

Nature Conservation Society of South Australia Inc received $21 980 through the Threatened Species Network Community Grants in 2003–04, part of which was for implementation of actions under a Threatened Species Network draft recovery plan in three areas critical to plant recovery - grazing management, weed management, community awareness and involvement.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
