État de la populationTexte officiel évaluation IUCNExpert
Plants occur in all sizes throughout both studied subpopulations. The two subpopulations, totalling approximately 10,000 plants, are approximately equal in number of plants and land area, and collectively occupy roughly 7.5 ha, (density approx. 1,350 plants∙ha-1). Observations of numerous seedlings together with the fact that many plants possess cones in a given year is an indication that the two known subpopulations are actively and successfully reproducing (Schutzman et al. 2008).

Description complète des menacesTexte détaillé évaluation IUCNExpert
All known sub populations occur within a single protected area. Potential threats include poaching, inadequate governmental protection, agricultural encroachment, and natural disasters that could endanger this narrowly endemic species. Barring these threats, the subpopulations appear robust with apparent excellent seedling recruitment (Schutzman et al. 2008).
