Threats:

Major Threats

The major threat to this species is intensive collection for consumption at subsistence levels, and for local, national and international trade. Some populations have also probably been eliminated locally due to forest clearance.

Conservation Actions:

Conservation Actions

This species inhabits a great number of protected areas throughout much of its range, and is protected by the Wild Animals Reservation and Protection Act (WARPA), 1992, in Thailand. There is a need to ensure that the harvesting of this species from the wild is managed in a sustainable manner (this species could benefit from commercial farming). Clarification of the taxonomy of the blythii complex is necessary to identify cryptic species of conservation concern.

Blyth's River frog:

Limnonectes blythii, known under many common names such as Blyth's river frog, Blyth's frog, giant Asian river frog, (ambiguously) giant frog, and with many other names, is a species of frog in the Dicroglossidae family. It is found in area stretching from Myanmar through western Thailand and Malay Peninsula (Malaysia, Singapore) to Sumatra and Borneo (Indonesia). Earlier records from Laos and Vietnam are considered misidentifications.[2]



Description[edit]

Limnonectes blythii are very larges frogs. Females grow to a snout–vent length of 90–260 mm (3.5–10.2 in) and males to a slightly more modest 85–125 mm (3.3–4.9 in). Large adults can weigh more than 1 kg (2.2 lb). The skin is smooth in the dorsum, with or without scattered tubercles or longitudinal skin folds. They are brownish, grey or yellowish above and white or yellowish. They may or may not have a vertebral stripe in their backs.[3][4]

Habitat[edit]

These frogs inhabit streams with gravel and boulders in primary and secondary evergreen forest. Males build a nesting hollow in a sandy streambed area, and the larvae develop in streams.[1] They can also be found far away from streams.[3]

Utilization and conservation[edit]

The major threat to this species is collection for food, both for local consumption and for trade. It is also locally impacted by habitat loss.[1]

Justification

Listed as Near Threatened because this species is in significant decline (but at a rate of less than 30% over ten years) because it is being over-harvested for food and because its habitat is shrinking, making the species close to qualifying for Vulnerable.

Population:

Population

The population status of this species is locally variable, ranging from uncommon in western Thailand to very common in areas where harvesting does not occur in Peninsular Malaysia. It is generally less common in easily accessible areas near human habitation than in similar inaccessible areas, indicative of depleted populations due to harvesting. Cessation of harvesting leads to population recovery in five to 10 years (P. van Dijk pers. comm.).
