Scientific Name: Enhydris vorisi Murphy, 2007

Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2010
Date Assessed: 2009-02-15
Assessor(s): Murphy, J.
Reviewer(s): Livingstone, S.R., Elfes, C.T., Polidoro, B.A. & Carpenter, K.E. (Global Marine Species Assessment Coordinating Team)
Justification:
This species is considered to be endemic to the Ayeyarwady River delta in Myanmar, although it is only known from the vicinity of Maubin and has an estimated area of occupancy of less than 500 km². It is threatened by extensive habitat decline throughout its restricted range due human development, pollution and dredging. It is listed as Endangered. There is very little information on the distribution, ecology and threats to this species and further study is recommended.

Geographic Range [top]

Range Description:This species is known only from the vicinity of Maubin, Ayeyarwady Division, Myanmar. Information for this species is from nine specimens collected from this location. It is thought that this species is endemic to the Ayeyarwady river delta, which as total extent of occurrence of at least 20,000 km². However, this species is estimated to have an area of occupancy of less than 500 km².

Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The specimens were taken from a freshwater swamp forest habitat but little is known about the habitat and biology of this species (Murphy 2007).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): This species currently inhabits a severely degraded habitat. The sedimentation rate of the Ayeyarwady River is extremely high due to continued deforestation occurring upstream (Murphy 2007). There is also pollution and dredging activities in the river. The Ayeyarwady River delta is very densely populated which has contributed to ongoing urban and coastal development and modification of river drainages.

Conservation Actions [top]

Conservation Actions: There are no conservation measures known for this species. Additional research into the effects of the threats on the species are recommended, as well as on the distribution, and ecology of the species.
