9.ECOLOGICAL COMMUNITIES THAT COULD BECOME ELIGIBLE FOR LISTING IN A HIGHER CATEGORY OF ENDANGERMENT AND JUSTIFICATION

Provide details and justification of EPBC Act listed threatened ecological communities that, due to the impacts of the threatening process, could become eligible for listing in another category representing a higher degree of endangerment. For each ecological community please include:

the complete title (published or otherwise generally accepted), category that the item is currently listed in and the category it could become eligible for listing in;
data on the current status in relation to the criteria for listing (at least one criterion for the current listed category has been previously met);
specific information on how the threatening process significantly threatens this ecological community; and
information on the extent to which the threat could change the status of the ecological community in relation to the criteria for listing. This does not have to be the same criterion under which the ecological community was previously listed.

Criterion C: Adversely affected listed species or ecological communities

10.SPECIES ADVERSELY IMPACTED AND JUSTIFICATION

Provide a summary of species listed as threatened under the EPBC Act, that are considered to be adversely affected by the threatening process. For each species please include:

a. the scientific name, common name (if appropriate) and category of listing under the EPBC Act; and

b. justification for each species that is claimed to be affected adversely by the threatening process.

Species Scientific Name	Common Name	Current Category Listing	Justification for each species that is claimed to be affected adversely by the threatening process
Liopholis slateri slateri	Slater’s Skink	Endangered	“Total population currently thought to be 200-300 animals. No threatening processes have been positively demonstrated, although degradation of its alluvial habitat as a result of invasion by the introduced buffel grass and associated changes in fire regimes appears the most likely causes of the species’ decline. In particular, the decline and disappearance of Slater’s skink is correlated with the introduction of buffel grass (Cenchrus ciliaris) into central Australia in the late 1960s. This weed has radically altered the vegetation structure and species composition of drainage systems in central Australia. Buffel grass is now the dominant ground cover at the type locality and surrounding alluvial areas.”
Croitana aestival	Desert Sand Skipper	Endangered	The spread of Buffel Grass (Cenchrus ciliaris) is expected to have degraded the habitat at all known locations and it is believed this will lead to the continued decline of the species (Braby et al. 2007; TSSC 2006v) through loss of their native grass larval food plants.
Minuria tridens	Minnie Daisy	Vulnerable	Minuria tridens is threatened by the invasion of the exotic perennial grass, Cenchrus ciliaris (buffel grass) into core habitat areas. The Alice Springs Municipality sites are most severely affected.
Olearia macdonnellensis	MacDonnell Ranges Olearia	Vulnerable	O. macdonnellensis is threatened by wildfire (Kerrigan et al. 2006). Buffel-grass is highly abundant in run on areas throughout the MacDonnell Ranges and is therefore likely to occupy the creek lines where O. macdonnellensis occurs.
Acacia undoolyana	Undoolya Wattle	Vulnerable	Decline is inferred due to an increase in fire frequency (Soos et al. 1987; Latz 1992; Pitts et al. 1995). Widespread infestations of the introduced buffel grass Cenchrus ciliaris may detrimentally affect this species, particularly by increasing fire frequency and intensity in adjacent alluvial land systems, such that fires can more readily spread into Acacia undoolyana stands.
Leiopoa ocellata	Malleefowl	Vulnerable	Continued invasion of buffel grass into arid woodlands will increase the fire frequency, removing key food plants and habitat in which they build their mounds – especially mulga / minyura woodlands and shrublands.
Dasycercus cristicauda	Mulgara	Vulnerable	For all these species the invasion of buffel grass will significantly change the structure and composition of their preferred habitat and remove key resources through competition and wildfire.
