Scientific Name: Pedostibes rugosus
Species Authority: Inger, 1958
Common Name(s):
English Marbled Tree Toad, Inger's Asian Tree Toad

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
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)
Justification:
Listed as Near Threatened since although this species is still relatively widely distributed, it depends on streams in areas of closed forest habitat, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining very rapidly due to widespread forest loss within its range, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description:This species is known only from the forests of northern Borneo in Sabah and Sarawak (Malaysia), Kalimantan (Indonesia) and Brunei Darussalam. It is likely to occur more widely than currently recorded. It is generally a lowland species occurring between 150 and 1,050m asl.

Population [top]

Population: The population status of this species is unknown.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It has been recorded from hilly lowland, and submontane, tropical primary moist forest. It is an arboreal species that breeds in small, clear, rocky streams. It might possibly occur in areas that have previously been used for shifting cultivation, but it cannot adapt to significantly modified habitats.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The major threat to this species is habitat loss and fragmentation due to deforestation.

Conservation Actions [top]

Conservation Actions: It is present in a number of protected areas including Batu Apoi (Brunei), and Lanjak Anteroi and the Crocker Range (both in Sabah). The protection of lowland forests in Sabah and parts of Sarawak now provide stable habitat for this species, but expansion of this protection to hilly lowland forests in Kalimantan is needed.
