In 2013, Bat Conservation International listed this species as one of the 35 species on its worldwide priority list for conservation.[3] It is threatened by habitat loss. There are estimated to be approximately 500 individuals of the subspecies E. s. rotensis.[4] Currently known to roost in only three caves, E. s. rotensis is vulnerable to changes in the local habitat, including indirect impacts caused by invasive species such as goats[4] which limit its carrying capacity.
