Justification of Red List category
This species is known from a very small area of marshland surrounding a single Andean lake, where habitat quality is declining, mainly because of pollution and high grazing pressure. Recent studies suggest a population of around 4,100 mature individuals, but the population may be sensitive to human-induced changes of the water level. The species consequently qualifies as Endangered.
