Until now, only one population, consisting of ca. 200 individuals, has been discovered in the vast reserve of 2704 km2. As there is no threat currently affecting the quality of its habitat and there is also a considerable number of mature individuals, the species is here preliminarily assigned a status of Least Concern (LC) according to the guidelines for using the IUCN Red List Categories and Criteria (
