État de la populationTexte officiel évaluation IUCNExpert
Zamia manicata is known from at least 12 localities in the Darien region of Colombia and Panama. In Panama, subpopulations are present in forest-dominated landscapes with low disturbance by human activities, therefore it is suspected that the total population size could be large. In Colombia, a few demographic studies have been carried out for the species (years 2010 to 2017 in several localities in the Antioquia province of Colombia). These studies, in addition to general field surveys, suggest that several subpopulations have large numbers of adults (more than 2,500 individuals) and have positive growth rates. It is very likely that the species has more subpopulations, therefore further research on population distribution and abundance is required.

Description complète des menacesTexte détaillé évaluation IUCNExpert
Most subpopulations of the species occur in rainforests with low disturbance by human activities in Panama and the Panama/Colombia border. Nevertheless, several subpopulations in Colombia (Antioquia province) occur in landscapes threatened with high deforestation rates, caused by agricultural and urban expansion (cattle ranching, timber plantations and some crops like bananas), and persist in forest fragments further degraded by logging and hunting.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
This species is listed in CITES Appendix II. Zamia manicata has many subpopulations occurring in healthy forests, therefore they are suspected to be viable. Some subpopulations are distributed within protected areas (National Parks "Darien" in Panama and "Los Katios" in Colombia) and the species has been recorded in some ex situ collections (Medellin, Quindio, Tulua, Bucaramanga Botanical Gardens in Colombia). Nevertheless, many subpopulations in Colombia (Antioquia province) are threatened, and some actions are required to improve population and habitat viability there. Colombia has a national conservation action plan for Cycads, and some specific conservation actions for the species have been proposed.
