Description complète des menacesExpert

The number of individuals is rapidly decreasing because of illegal collection for cultivation. There is also direct damage by trampling and its highly restricted distribution is considered to pose a threat to the species (Kagoshima Prefecture 2003, Ministry of the Environment 2011). Habitat change caused by logging was mentioned as a threat in 1989 when the species was beginning to decline.
