Criterion A: non-EPBC act listed species/ecological communities

6.SPECIES THAT COULD BECOME ELIGIBLE FOR LISTING AND JUSTIFICATION


Provide details and justification of non-EPBC Act listed species that, due to the impact of the key threatening process, could become eligible for listing in any category, other than conservation dependent. For each species please include:

  1. the scientific name, common name (if appropriate), category it could become eligible for listing in;

  2. data on the current status in relation to the criteria for listing;

  3. specific information on how the threatening process threatens this species; and

  4. information on the extent to which the threat could change the status of the species in relation to the criteria for listing.



Species / Community Scientific Name

Common Name

Category it could become listed in

Data on Current status

Specific Information on how KTP threatens species

Information on the extent to which the threat could change the status of the species in relation to the criteria for listing

IUCN category under which it could become listed through ongoing invasion and threats of Buffel Grass

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.

APY Rare and Threatened Plant Management Plan

(Paltridge et al 2009)



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.

Critically Endangered: A.3.B.2.b.i.

APY Rare and Threatened Plant Management Plan

(Paltridge et al 2009)



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.

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.

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
