État de la populationTexte officiel évaluation IUCNExpert
A population study of this species was made in two localities and other which were rigorously surveyed for three years (Watve in litt.). The population size was estimated to be 1,500 mature individuals with the largest subpopulation containing 500 individuals. A decline in mature individuals was not observed from 2004-2006 although habitat modifications were recorded in some of the localities. Population trend for the global population is not clear.

Description complète des menacesTexte détaillé évaluation IUCNExpert
The main threats for this species are habitat disturbance due to construction of windmills leading to major changes in surface drainage. Removal of soil and increased garbage also disturbs the species. In one site, increased tourist pressure leads to trampling of primary habitat. This species being a well known attraction to plant lovers and photographers is often targeted by the tourists leading to habitat disturbance.
According to an earlier flora, one locality is threatened by the construction of a dam. This is highly improbable now (A. Watve pers. obs 2010). The site is remote, at the top of the mountain, highly protected as it is core zone of a newly created Wildlife Sanctuary (Chandoli) and perhaps is the best protected location for this species.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Ex-situ conservation efforts have been done by individuals and institutions including Botanical Survey of India, however none have been successful as the habitat requirements are too specific. More concentrated efforts are needed for a long term for ex-situ conservation. At present conservation of habitats is the best measure (A. Watve pers. obs. 2010) as well as reducing impacts mentioned in the threats section.
