Desert Rivers of the Central Ranges and Finke region
|
Vulnerable
|
In a state of rapid decline due to invasion of feral animals and plants
|
Desert rivers of the Central Ranges and the Finke River system are threatened by the invasion of buffel grass, which initially colonises in the ephemeral creek beds, from where it spreads out to surrounding areas. Uncontrolled, hot wildfires from this buffel grass invasion then destroys significant Red Gum Eucalyptus camaldulensis woodlands which are important habitat for birds and mammals.
|
Uncontrolled spread of buffel grass will cause a rapid decline in desert river systems

Petrogale lateralis MacDonnell Ranges Race
|
Black-footed rock-wallaby / Warru
|
Vulnerable
|
Endangered
|
Declining populations across its range.
|
Buffel grass promotes hot wildfires which can destroy fire sensitive vegetation on which warru rely, such as Figs (Ficus) and Spearbush (Pandorea sp.). Uncontrolled spread of buffel grass will threaten remaining populations of warru
|
Uncontrolled buffel grass encroachment on warru habitat and associated negative impacts could see a population size reduction of > 50% over the next ten years

Ongoing spread of buffel grass will change the structure of preferred open feeding grounds of Tjakura, as well as promoting frequent wildfires which will completely change the structure of preferred vegetation.

Stipiturs mallee

Mallee Emu-wren
|
Endangered
|
Critically Endangered
|
Few remaining populations. Extent of occurrence estimated at The extent of occurrence is conservatively estimated at 3856 km² and declining very rapidly. Estimated population size 1440 to 2814 mature individuals and declining rapidly
|
Mallee Emu-wrens are restricted to Triodia and heath of particular age since fire. The invasion of buffel grass on the sandy country in which they live would result in an increase in fire frequency and replacement of native vegetation with buffel grass which is inappropriate for mallee emu-wrens replacement by buffel will remove habitat
|
An uncontrolled infestation of buffel grass with associated wildfire in the primary distribution in western Victoria could see could see population size reduced rapidly to fewer than 250 individuals and a continuing decline with no subpopulations estimated to contain more than 50 mature individuals

Notomys fuscus
|
Dusky Hopping Mouse
|
Vulnerable
|
Endangered
|
Has a restricted distribution to refuges during dry periods.
|
The refuges of the dusky hopping-mouse are in fire sensitive habitats which will be destroyed with the large fires that buffel grass monocultures can carry. The distribution of the dusky hopping-mouse corresponds with highly suitable buffel grass habitat, particularly along the ephemeral creeklines of the channel country.
|
The invasion of buffel grass into refuge habitats and subsequent negative effects could see an observed population size reduction of >50% over a ten year period.

Croitana aestival

Desert Sand Skipper
|
Endangered
|
Critically Endangered
|
Four records. The extent of occurrence for the Desert Sand-skipper estimated to be less than 100 km²
|
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.
|
The invasion of buffel grass into Desert Sand Skipper habitat could see the area of occupancy reduced to less than 10km2 and a continuing decline

Olearia macdonnellensis
|
NA
|
Vulnerable
|
Endangered
|
Confined to the MacDonnell Ranges Bioregion where it is currently known from several isolated populations, mainly in the central-western portion of the MacDonnell Ranges. Total area of occupancy is estimated to be < 20 km2. All populations are considered necessary for its long-term survival and recovery. Buffel grass listed in Recovery Plan as key threat.
|
Olearia macdonnellensis is likely killed by fire and recovery time requires low fire frequencies. The invasion of buffel grass is likely to increase the threat of fire and these populations. Once established, buffel-grass has the ability to negatively affect both M. tridens and O. macdonnellensis directly through resource competition. This is likely to be especially intense at early life stages, leading to heightened recruitment failure if germination and establishment requirements can no longer be met. O. macdonnellensis would be particularly affected if, like many of its congeners, it has a light requirement for germination. Both species are additionally potentially threatened by increased fire intensity and frequency in severely affected sites. Buffel-grass produces large amounts of biomass which, when dried, represents a significant increase in site fuel load.
|
An uncontrolled infestation of buffel grass within the known population could see an Area of Occupancy of less than 500km2 and a continuing decline in extent of occurrence and area of occupancy

Minnie Daisy
|
Vulnerable
|
Endangered
|
Minuria tridens is restricted to approximately 20 scattered populations on south facing slops of the MacDonnell Ranges IBRA region. Area of Occupancy less than 2000km2
|
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. Once established, buffel-grass has the ability to negatively affect both M. tridens and O. macdonnellensis directly through resource competition. This is likely to be especially intense at early life stages, leading to heightened recruitment failure if germination and establishment requirements can no longer be met. O. macdonnellensis would be particularly affected if, like many of its congeners, it has a light requirement for germination. Both species are additionally potentially threatened by increased fire intensity and frequency in severely affected sites. Buffel-grass produces large amounts of biomass which, when dried, represents a significant increase in site fuel load.
