Red List Category & Criteria: Near Threatened ver 3.1

Justification:
This species is listed as Near Threatened as although it is restricted to a small range and number of locations and the number of individuals is small, favourable management (including protection of the most important population) has meant that habitat quality and numbers are not thought to be declining. Regular monitoring of both species and habitat is needed to confirm the continuing effectiveness of this management.

Geographic Range [top]

Range Description: Menura alberti is confined to a relatively small area of rainforest between Blackwall Range, New South Wales, and Mistake Range, Queensland, Australia. New South Wales is thought to support less than 800 pairs, with highest densities at Whian Whian State Conservation Area in Nightcap Range. Subpopulations are also found along Tweed, McPherson and Richmond Ranges. An isolated group of less than 10 birds persists in the Blackwall Range. In Queensland, the population may be of a similar size, although possibly smaller, and occurs patchily from Lamington National Park around Main Range to Mistake Range, with a small population on Tamborine Mountain. In optimal habitat, territories are widely spaced with a density of approximately five pairs/km2.

Population [top]

Population: Garnett and Crowley (2000).

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It lives in moist forest, mostly above 300 m with highest densities on poorer soils which develop a deep leaf-litter. It favours areas with Antarctic Beech Nothofagus moorei and wet sclerophyll forest with a dense understorey of rainforest plants, but is absent from some rainforest types, including complex notophyll vine forest on high nutrient soils and from dry sclerophyll forest. It feeds on terrestrial invertebrates.

Systems: Terrestrial

Threats [top]

Major Threat(s): Much of the species's habitat was cleared in the 19th century. Until recently, the major threat was intense forest management, particularly in what was Whian Whian State Forest where proposals existed to allow replacement of optimal wet sclerophyll habitat with unsuitable Eucalyptus plantations. This area is now protected in the Whian Whian State Conservation Area (I. Gynther in litt. 2007). Previously disturbed areas may support a dense growth of lantana Lantana camara which reduces habitat suitability. Most subpopulations are now under relatively secure tenure, although the isolated populations at Blackwall Range and Tamborine Mountain are threatened simply because they are so small, and densities are unusually low near areas of closer settlement. Greater protection of suitable habitat on private land is occurring through the establishment of voluntary conservation agreements and this will help secure some subpopulations. Fire could be a threat in exceptionally dry years, especially to outlying subpopulations, although fire at intervals of several centuries is a natural feature of these environments. Nevertheless, the impacts of climate change on fire frequency and intensity, as well as on habitat quality in general, may need to be considered for the species in the future.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
A study of the habitat distribution and population density has been completed. Whian Whian State Forest, which was formerly threatened with conversion to Eucalyptus plantations, became protected as part of the Whian Whian State Conservation Area in July 2003. Voluntary conservation agreements on private land have given greater protection to suitable habitat (including Nature Refuge designation in Queensland), several state forests where the species occurs have been converted to national park status in Queensland, and a Border Ranges Rainforest Biodiversity Management Plan has been developed, encompassing the entire distribution of the species and identifying actions to enhance the quality and extent of habitat.

Conservation Actions Proposed
Determine the extent of isolation between forest patches. Undertake habitat restoration to provide greater extent and quality of habitat and improved connectivity between remnants. Protect more habitat on private land through voluntary conservation agreements. Carry out regular population monitoring. Ensure adequate fire protection is in place, particularly in dry years.
