- Conservation status:
- EPBC Act 1999: V
- IUCN (2000); X
- NRE (2000): E
- Endemic to Victoria - Victorian Highlands - Northern Fall Bioregion, but known only from the type locality near Cobungra. No precise records exist to indicate its former distribution, but likely to have been a short-range endemic in the Omeo area.
- Probably extinct. Only known from a single population consisting of fewer than 15 plants at the type locality. No plants have been seen in recent years. No records exist to indicate its former distribution, but P. morganii is likely to have been naturally rare with an extremely small population size.
- Eucalyptus pauciflora subsp. pauciflora open forest at about 1,000 m above sea level (Backhouse and Jeanes 1995). Sunny side of a small ridge running down to Spring Creek. Soil is inclined to be clayey, with a little quartz and sandstone among it (Nicholls 1930). Critical habitat has not been determined.
- Reservation status:
- Not reserved.
- Private property.
|Current threats||Perceived risk|
|Weed invasion||Likely to be high - habitat has been improved for pasture.|
|Grazing/pest animals||Extremely high - site is grazed by cattle.|
|Inappropriate fire regimes||Probably low at present.|
|Site disturbance||Extremely high - habitat altered by ring-barking trees.|
|Potential threats||Perceived risk|
|Illegal collection||Low - no evidence of collection in the past.|
|Ecology/biology||Moderate - conditions for maintenance of pollinator and fungal activity unknown; small population size.|
Revise current conservation status to Extinct.
Recovery actions undertaken:
- Searches have been conducted in the past by a number of individuals.
Issues specific to recovery:
- There is strong evidence to indicate that P. morganii is extinct. Searches by J. Jeanes and a number of orchid society members, field naturalists and other enthusiasts over the last 10 years have failed to re-locate the known population or any other populations in the area.
Overall recovery strategy:
Revise the current conservation status to Extinct.
