Little is known about the current population of the species, although its believed to be as large as 10,000 individuals given its broad distribution in Sumatra. L. schwanenfeldii has also not been recorded in Java for over a century and surveys are required to determine if the species is still extant within the area. It has been classified as 'Least concern' by the IUCN Red List given its broad distribution and range overlapping with protected areas. Further studies are required to understand its current population size and how current threats are impacting the species.
