From the IUCN Red List Species Account:

 

Range Description

This species is known from Thailand (Peninsular: Ranong, Surat Thani, Phangnga, Krabi, and around the boarder of Satun, Songkhal and Malaysian Kedah), Malaysia (Peninsular, Penang, Tioman, Sabah and Sarawak) (Taylor 1962, Berry 1975), Indonesia (Kalimantan) and Brunei Darussalam occurring below 700 m asl. It probably occurs more widely than current records suggest, especially in areas between known sites. Confusion between Rana signata and Rana picturata makes many old Bornean records suspect.

Habitat and Ecology

It is abundant in lowland forests, including swamp and heath forest, and is commonly found in the riparian vegetation along stream banks. Metamorphs disperse through the forest and when they are half grown they return to the stream banks. Tadpoles develop in quiet side-pools at the edge of streams.

Population

It is generally a common species.

Population Trend

Unknown

Major Threats

Deforestation is the principal threat to this species.

Conservation Actions

It is found in protected areas on the Malay Peninsular (e.g. Temengor Forest Reserve, Ulu Muda Forest Reserve, Pasoh Forest Reserve) and in Borneo (Sabah and Sarawak). Protection of lowland tropical forest is the main conservation measure required. The taxonomic status of this species is currently under investigation.

Taxonomic Notes

The highland frogs usually attributed to Hylarana signata might represent a separate taxon. The status of the Tioman population is likewise unclear.
