This species is classified as Near Threatened because it has a very small range, in which its habitat is declining but is not severely fragmented, and a moderately small population which is thought to be declining owing to heavy trapping pressure and habitat loss and degradation.
|Previously published Red List assessments:||
|Range Description:||Rallina canningi is endemic to the Andaman Islands, in the Bay of Bengal, India, where it is known from North, Middle and South Andaman and may occur on other islands. Formerly considered very common based on high trapping rates, there were very few recent records until survey work in 2004 found it to be fairly common in suitable habitat (Ezhilarasi and Vijayan 2008).|
|Continuing decline in area of occupancy (AOO):||Unknown|
|Extreme fluctuations in area of occupancy (AOO):||No|
|Estimated extent of occurrence (EOO) - km2:||4500|
|Continuing decline in extent of occurrence (EOO):||Unknown|
|Extreme fluctuations in extent of occurrence (EOO):||No|
|Continuing decline in number of locations:||Unknown|
|Extreme fluctuations in the number of locations:||No|
|Upper elevation limit (metres):||700|

|Population:||The population is estimated to number 10,000-25,000 individuals in total, roughly equivalent to 6,700-17,000 mature individuals.
Trend Justification: This species is estimated to be declining at a slow to moderate rate, owing primarily to heavy trapping pressure.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is resident in marshes and along streams within or at the edge of forest, and occasionally mangroves, favouring dense vegetation including tangled thickets of rattan and pandanus.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||3.6|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||It is known to be under heavy trapping pressure, and may also be declining as a result of increasing habitat destruction and degradation through forest clearance for settlements, cultivation, road construction, and other infrastructural projects. Introduced predators are another potential threat.|
Conservation Actions Underway
It is known from Chidiyatapu Biological Park. Conservation Actions Proposed
Conduct surveys throughout its range to determine its current population size. Asses the extent and impact of habitat loss on populations. Quantify the impact of trapping on populations. Regulate trapping if appropriate. Protect large areas of suitable habitat at key sites, in both strictly protected areas and community-led multiple use areas.
