Pleurozia gigantea has a widespread distribution in the tropics, occurring in Africa, south and east Asia, and the Pacific Ocean region.Within its distribution range the species occurs in geographically isolated areas of hyper-oceanic or montane climate. Although the number of mature individuals is not known, it is very likely much higher than the thresholds for a threatened listing under criteria C and D. Globally, the population is likely to be declining, but probably not at a rate to qualify the species for listing as threatened.
