État de la populationTexte officiel évaluation IUCNExpert
Zamia huilensis is known from a few subpopulations (five subpopulations identified to date). No detailed demographic study has been carried out for the species, but general field surveys suggest that known subpopulations have small numbers of adults (less than 250 individuals). It is possible that the species has more subpopulations, therefore further research on population distribution and abundance is required.

Description complète des menacesTexte détaillé évaluation IUCNExpert
All subpopulations of the species occur in landscapes threatened with high deforestation rates, caused by agricultural and urban expansion, mostly forest destruction for cattle ranching and crops. The forest patches where subpopulations remain are small (less than 500 hectares) and they are degraded by human activities like logging and hunting.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Zamia huilensisis not present in any protected area. The species has ex situ collections in botanical gardens in Colombia (Medellin, Tolima Gardens). Urgent actions are required to improve population and habitat viability in the long term. The conservation action plan for Colombian Cycads has proposed specific conservation actions for the species, however there is no species conservation strategy properly funded to this date.
