This species is poorly known and its distribution is uncertain. It is likely threatened by the loss of mangrove habitat throughout its range, primarily due to extraction and coastal development. However, more information on its distribution, population status, habitat requirements and threats is needed. It is listed as Data Deficent.
|Previously published Red List assessments:|
|Range Description:||This species is found in India (Orissa and Sunderbands), Bangladesh, and pennisular Malaysia. It is patchily distributed in Indonesia in northern Sumatra and Kalimantan, the southern coast of Sulawesi, Halmahera, Ambon, Aru, and Irian Jaya. The distribution in the Philippines is questionable.|
Native:Bangladesh; India; Indonesia; Malaysia
|FAO Marine Fishing Areas:|
Indian Ocean – eastern; Pacific – western central

|Population:||There is no species-specific population information. However, it is assumed that the general declines in mangroves around the world apply to this species.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is not well known. It grows in upstream mid intertidal areas.|
|Use and Trade:||Unknown.|
Although local estimates are uncertain due to differing legislative definitions of what is a 'mangrove' and to the imprecision in determining mangrove area, current consensus estimates of mangrove loss in the last quarter-century report an approximately 23% decline in mangrove areas in countries within this species range since 1980 (FAO 2007).
All mangrove ecosystems occur within mean sea level and high tidal elevations, and have distinct species zonations that are controlled by the elevation of the substrate relative to mean sea level. This is because of associated variation in frequency of elevation, salinity and wave action (Duke et al. 1998). With rise in sea-level, the habitat requirements of each species will be disrupted, and species zones will suffer mortality at their present locations and re-establish at higher elevations in areas that were previously landward zones (Ellison 2005). If sea-level rise is a continued trend over this century, then there will be continued mortality and re-establishment of species zones. However, species that are easily dispersed and fast growing/fast producing will cope better than those which are slower growing and slower to reproduce.
In addition, mangrove area is declining globally due to a number of localized threats. The main threat is habitat destruction and removal of mangrove areas. Reasons for removal include cleared for shrimp farms, agriculture, fish ponds, rice production and salt pans, and for the development of urban and industrial areas, road construction, coconut plantations, ports, airports, and tourist resorts. Other threats include pollution from sewage effluents, solid wastes, siltation, oil, and agricultural and urban runoff. Climate change is also thought to be a threat, particularly at the edges of a species range. Natural threats include cyclones, hurricane and tsunamis.
|Conservation Actions:||There are no conservation measures specific to this species, but its range may include some marine and coastal protected areas. Continued monitoring and research is needed for this species as little is known about its distribution, habitat or ecology, or impact of major threats. It is recommended that mangrove areas should be included in marine and coastal protected areas.|
