From the IUCN Red List Species Account:

 

Range Description

This species complex is found on Mindanao, Basilan, Bohol, Camiguin, Samar and Leyte Islands in the Philippines, from 1,200-1,800m asl, as well as on Sulawesi, Indonesia.

Habitat and Ecology

It inhabits undisturbed and disturbed streams and rivers in lower montane and lowland forests. It breeds and deposits egg clutches in quiet side pools of forested riverine habitats.

Population

It is common to very common where its habitat remains intact, although some populations are in decline because of over-exploitation.

Population Trend

decreasing

Major Threats

On Sulawesi, the major threat to the populations of this species is human exploitation for both local consumption and international trade. In the Philippines, threats include habitat loss due to agriculture and logging, and pollution of streams and rivers from agricultural pesticides, herbicides, and mine-tailings, as well as harvesting for human subsistence and for international export.

Conservation Actions

The range of this species includes a few protected areas. It apparently coexists parapatrically with its sibling species in Lore Lindu National Park, and it extends to Poso and Tanah Toraja. Conservation measures for this species must include the protection of remaining rainforest, especially riverine habitats and gallery forests. Levels of human exploitation need to be investigated to determine if this needs to be managed more sustainably.

Red List Status

Near Threatened (NT)

Rationale

Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss through much of its range, and over-harvesting for food, thus making the species close to qualifying for Vulnerable.

Taxonomic Notes

The use of the name Limnonectes magnus as applied to both Philippine and Sulawesi taxa is a taxonomic arrangement in need of revision. The Sulawesi populations referred to this species have already been shown to be distinct species based on molecular analysis, but have not yet been named.
