Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,iii,iv,v) ver 3.1
Year Published: 2010
Date Assessed: 2009-06-30
Assessor(s): Cogger, H.G.

Justification:
Delma torquata has been assessed as Vulnerable under criterion B1 because it has an extent of occurrence of less than 20,000 km², it is now only found in four locations and is experiencing decline in extent and quality of habitat due to the impact of habitat degradation and invasive species. The observed restriction of this species' range illustrates that habitat loss and degradation due to land clearing and invasive species is causing a decline in the population abundance of this species. Conservation measures, such as the establishment of protected areas, are required to supplement the current legislation that exists for this species.
History:
1996 Vulnerable (Baillie and Groombridge 1996)
1996 Vulnerable
1994 Vulnerable (Groombridge 1994)

Geographic Range [top]

Range Description: This species occurs in southeastern Queensland, Australia, and was previously restricted to 13 localities (Porter 1998), including areas in the Brigalow Belt (Wilson 2003). Its range may now be further reduced as it is only known from four of these sites; Mount Crosby, Lake Manchester, Karana Downs and the Bunya Mountains (Department of the Environment and Water Resources 2007). The Bunya Mountains are disjunct from the other three localities. The area in which this species is distributed is approximately 3,283 km² however, its extent of occurrence is closer to 20,000 km².

Population [top]

Population: This species is rare (Porter 1998).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species occurs on rocky outcroppings in dry, open eucalyptus-acacia woodlands with an under-storey of grass and shrubs (Porter 1998). It is known to inhabit leaf litter and has also been found under logs and stones (Ryan 2006).
Systems: Terrestrial

Threats [top]

Major Threat(s): This species is thought to be highly sensitive to habitat disturbance (Porter 1998). Land clearing for agriculture has occurred in this region and the remaining habitat has become fragmented and degraded by invasive plants and animals (Wilson 2003).

Conservation Actions [top]

Conservation Actions: There are recovery and management plans in place for this species, and it is listed as a species with special protection status. Further research and monitoring of its population is required to ensure that the current legislation is effective. Conservation measures, including the establishment of protected areas, should be carried out to ensure that habitat loss within this species' range is reduced.
