Scientific Name: Pseudochirulus herbertensis (Collett, 1884)
Common Name(s):
English Herbert River Ringtail Possum, Herbert River Ringtail
Taxonomic Notes: Groves in Wilson and Reeder (1993) lists this species as Pseudocheirus herbertensis.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2015-06-15
Assessor(s): Burnett, S. & Winter, J.
Reviewer(s): Johnson, C.N. & Hawkins, C.
Listed as Least Concern because, although its extent of occurrence is less than 5,000 km2, it is common, lacks major threats, has a range that is mostly within the Wet Tropics World Heritage Area, and its population does not appear to be in decline.

Geographic Range [top]

Range Description:This species is known from the Atherton Tableland, Queensland, Australia. A smaller population occurs in the Mt. Lee block of rainforest, isolated from the main population by the Herbert River gorge. About 23% of rainforest has been cleared from the Atherton Tableland, isolating the Herberton Range/Hugh Nelson Range population. In a fragmented rainforest, the ringtail disappears from patches of habitat less than 20-30 ha in area (Maxwell et al. 1996).

Population [top]

Population:It is a common species (Winter and Moore 2008).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs in rainforest above 350 m in elevation (Winter and Moore 2008). There have been records of the species in wet sclerophyll forest adjacent to rainforest, however, it is unlikely that self-sustaining populations exist in eucalypt forest (Maxwell et al. 1996).

Threats [top]

Major Threat(s): There are no major threats to this species. Now that most of the ringtail's habitat is within the Wet Tropics World Heritage Area, threats from large-scale clearing or selective logging no longer apply. Short-term local extinctions in the fragmented rural landscape of the Atherton and Evelyn Tablelands is a threat. Longer-term genetic changes may take place in larger populations now isolated by clearing. Climate change is a potential threat that is likely to diminish its habitat in the future (Winter and Moore 2008).

Conservation Actions [top]

Conservation Actions: Most of its range is within protected areas. Recommended actions (Maxwell et al. 1996) for this species include: establish connectivity of the now isolated Herberton Range/Hugh Nelson Range population with the main population by reforestation; ensure continuity of habitat in the Mulgrave and North Johnstone catchments is maintained and even enhanced; reclaim the rural landscape of the Atherton and Evelyn Tablelands as suitable habitat through reforestation on private land to establish a connectivity network of rainforest corridors and patches; determine possible genetic demes within the presently continuous population of the main Atherton Unit population which may have resulted from population fragmentation as a result of climatic changes since the height of the last glacial period c. 18,000 years before the present; continue studies on socio-ecology, habitat requirements and effects of disturbance on the species.
