This stork is listed as Vulnerable because its population is suspected to be rapidly declining as a result of a variety of threats including hunting pressure, loss of nesting habitat, conversion and degradation of wetlands and agricultural changes and intensification. Conservation action is benefiting one key population in Cambodia, but rapid declines are likely to be ongoing elsewhere across the range.
