Appendix 3

Prasophyllum sp. (Shelley)

Conservation status:
EPBC Act 1999: Not listed
IUCN (2000): CR
NRE (2000): E
Endemic to Victoria - Victorian Northern Inland Slopes Bioregion (Burrowa-Pine Mountain area west of Corryong).
Specific details of population localities are held on DSE internal files.
Present range
Fewer than 15 plants known from a single population. Former abundance is unknown, but likely to have been naturally rare with an extremely small population size.
Winter-wet open riparian grassland within shrubby Eucalyptus dives - E. viminalis forest. Associated understorey species include Acacia melanoxylon, Daviesia latifolia, Derwentia derwentiana, Platylobium formosum, Pimelea linifolia subsp. linifolia. The ground layer typically includes Gonocarpus serpyllifolius, Glycine microphylla, Stellaria pungens, Poa sp., Centaurea erythraea and Hypochaeris radicata. Critical habitat has not been determined, but may require disturbed or open bare ground for recruitment.
Reservation status:
Reserved at Pheasant Creek FFR.
Parks Victoria, (Central Victoria Region: Tallangatta).
Current and potential threats and their risk:
Current threats Perceived risk
Weed invasion High - introduced grasses are abundant.
Grazing/pest animals Likely to be high - rabbits are common.
Inappropriate fire regimes Likely to be low - sites are long unburnt and plants are unlikely to rely on fire for regeneration.
Site disturbance High - site is close to the road and vulnerable to damage from heavy vehicles and roadside management.
Potential threats Perceived risk
Reservation status Inadequately reserved.
Illegal collection Low - no evidence of collection in the past.
Ecology/biology High - conditions for seed recruitment and maintenance of pollinator and fungal activity unknown; increased extinction risk due to small population size.
Recovery objectives:
Clarify taxonomy; maintain and/or increase existing population size; protect and manage habitat.

Recovery actions undertaken:

  • The site was visited during recovery plan preparation.

Issues specific to recovery:

  • There is doubt as to whether Victorian plants are P. canaliculatum sens. strict. or an undescribed species with affinities to P. canaliculatum. For the purposes of the recovery plan, the Victorian population is treated as a threatened short range endemic taxon, confined to the Pheasant Creek Flora and Fauna Reserve west of Corryong (D. Rouse, Centre for Plant Conservation Biology, Canberra).

Overall recovery strategy:

Taxonomy will be clarified and searches will be conducted at similar sites in north-east Victoria. Recovery actions will be revised if additional populations are discovered. Habitat will be managed at the known population to prevent accidental damage by vehicles and suppression of plants by over-abundant introduced grasses. Recovery will be jointly managed by DSE, and PV. Community involvement will be sought.
