This subspecies is listed as Vulnerable as although Molur et al. (2003) estimated about 4,800 individuals of M. f. umbrosa, nothing is known about the status following the December 2004 tsunami. The islands of Katchall and Little Nicobar were submerged during the tsunami, and it is believed to have affected the habitat of this taxon. The population is currently believed to be stable, although the construction of roads on Katchall Island and Great Nicobar Island, as well as hunting, may be having an impact.
2004 Near Threatened
