Reference / Information
|
Melaleuca fulgens subsp. corrugata
|
Wrinkled Honey Myrtle
|
Endangered
|
Endemic to Central Ranges IBRA region. All populations surveyed on the APY Lands contain very few individuals and are under threat from inappropriate fire regimes. Total Area of Occupancy in South Australia is less than 5km2. Total number of mature individuals is known to be less than 2500 individuals
|
Buffel grass promotes inappropriate fire regimes. The ongoing invasion of buffel grass across the Central Ranges IBRA ranges will not only outcompete this species but also increase the frequency and intensity of fires, posing a threat to small and isolated endemic plant species.
|
Warrants a current listing. Ongoing invasion of Buffel Grass and associated fires could see a population size reduction of >50% in next ten years.
|
Endangered: A.3. B.1.b.i.
|

|
Acacia tenuior
|
Central Ranges Wattle
|
Critically Endangered
|
Currently only two populations of A. tenuior known, the combination of small population size and disjunct population means that this species is at risk of extinction form catastrophic events posed from Buffel Grass
|
Buffel grass promotes inappropriate fire regimes. The ongoing invasion of buffel grass across the Central Ranges IBRA ranges will not only outcompete this species but also increase the frequency and intensity of fires, posing a threat to small and isolated endemic plant species.
|
Warrants a current listing. Ongoing invasion of Buffel Grass and associated wildfires could see a population size reduction of >80% in next ten years.

Eremophila willsii subsp. indeterminate
|
Musgrave Ranges Fuschia
|
Endangered
|
Currently only one population known from Australia, in APY Lands.
|
Buffel grass promotes inappropriate fire regimes. The ongoing invasion of buffel grass across the Central Ranges IBRA ranges will not only outcompete this species but also increase the frequency and intensity of fires, posing a threat to small and isolated endemic plant species.

Calostemma abdicatum
|
Everard Garland Lily
|
Vulnerable
|
Three known populations. Area of occupancy 0.04km2
|
Few known populations. Although known populations have many individuals, they are highly clumped in distribution making them vulnerable to major perturbations. Major buffel grass fire could see this species negatively impacted upon.
|
Warrants a current listing. Ongoing buffel invasion and associated inappropriate fire regimes could see current Area Of Occupancy of less than 2000km2 continue to decline (P. Lanf pers. comm.)
|
Vulnerable:B.2.b.
|
APY Rare and Threatened Plant Management Plan
(Paltridge et al 2009)
|
Acacia ammobia
|
Mount Connor Wattle
|
Vulnerable
|
Relatively abundant but restricted to Mt Connor / Uluru district of the Central Ranges Region
|
Highly sensitive to fire - killed by the mildest of fires and populations would require a fire frequency of less than 25 years. Buffel grass promotes very hot fires. Ongoing invasion of buffel grass in Central Ranges, therefore, poses a threat to this species in the long-term
|
Ongoing buffel invasion could see current number of individuals of >30% over next three generations
|
Vulnerable: A.3.
|
APY Rare and Threatened Plant Management Plan
(Paltridge et al 2009)
|
Goodenia brunnea
|
Central Ranges Goodenia
|
Vulnerable
|
Limited distribution - endemic to Central Ranges region. Total extent of occurrence 27,523km2
|
Goodenia brunnea is a primary successional plant following fire. If Buffel grass becomes the dominant successional species, it will outcompete Goodenia brunnea.
|
Ongoing buffel invasion and outcompeting Goodenia brunnea could see Extent of Occurrence to reduce less than 20,000km2
|
Vulnerable: B.1.b.i
|
APY Rare and Threatened Plant Management Plan
(Paltridge et al 2009)
|
Teucrium reidii
|
Showy Germander
|
Endangered
|
Small population sizes and limited distribution to APY Lands in Central Ranges region. Total known population size probably <5000 individuals nationally
|
Buffel Grass currently known to be significantly encroaching on two largest known remaining populations. Fire sensitive plant. Inappropriate fire regimes and competition from Buffel Grass will significantly affect this species status.
|
Ongoing buffel invasion and associated fire effects could see population size remain at fewer than 10,000 mature individuals and an estimated continuing decline of at least 10% within ten years
|
Vulnerable: C.1
|
NATIONAL RECOVERY PLAN FOR Olearia macdonnellensis, Minuria tridens (Minnie Daisy) and Actinotus schwarzii (Desert Flannel-flower)
|
Sminthopsis longicaudata
|
Long-tailed Dunnart
|
Vulnerable
|
Very scattered populations
|
Distribution limited to rocky ranges where buffel colonises rapidly. Vulnerable to habitat destruction through inappropriate fire regimes
|
Uncontrolled buffel invasion and associated fire effects could see population size remain at fewer than 10,000 mature individuals and an estimated continuing decline of at least 10% within ten years
|
Vulnerable: C.1
