Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Amphibia Anura Megophryidae

Scientific Name: Leptobrachella baluensis
Species Authority: Smith, 1931

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Robert Inger, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul Yambun
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Vulnerable, because its Extent of Occurrence is less than 20,000 km2 and its Area of Occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.

Population [top]

Population: It appears to be relatively abundant.
Current Population Trend: Decreasing
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: An inhabitant of sub-montane forests (oak-chestnut and mossy forest), adults are found in the leaf-litter, and on vegetation close to streams (Malkmus et al. 2002). Breeding occurs in small, clear, rocky, mountain streams.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat to this species is loss of habitat through logging, particularly in the Trus Madi portion of the species' range. Other parts of the range are threatened by forest clearance for pine and eucalyptus plantations.

Conservation Actions [top]

Conservation Actions: Several parks in Sabah, Malaysia, have large tracts of appropriate habitat, including Gunung Mulu, Crocker Range, and Gunung Kinabalu National Park. However, there remains a need for improved protection and maintenance of submontane forest in Kalimantan, Indonesia.
