This species his listed as Vulnerable as it is projected to undergo a rapid population decline over the next three generations as a result of increased demand for agricultural land due to human population increases, because of mining concessions in its stronghold of Guatemala, and due to increased hunting pressure.

|Range Description:||Cyrtonyx ocellatus occurs from south Mexico through Guatemala, El Salvador and Honduras to north Nicaragua (Carroll 1994). Guatemala has been identified as a stronghold for this species, and it has been sighted at 11 different sites since 2000. It is considered to be rare at all of these sites and there have been few additional recent records from Mexico, Honduras and Nicaragua. Considering this, and given that there have been no recent records from El Salvador, the total global population is now thought to number fewer than 10,000 individuals (Eitniear and Eisermann 2009, K. Eisermann in litt. 2010). It is thought to have once been widespread and fairly common across its range (R. Gallardo in litt. 2012), implying it has undergone a significant decline. |

|Population:||Although a full population census is yet to be completed, the species is thought to be rare at all known sites in Guatemala, there are few recent records from Mexico, Honduras and Nicaragua, and no recent records from El Salvador. Considering this, the population is thought to hold fewer than 10,000 individuals (K. Eisermann in litt. 2010), hence is best placed in the band 2,500-9,999 individuals, which roughly equates to 1,500-7,000 mature individuals.|
Trend Justification: This species is thought to have undergone a moderately rapid decline in the past decade. However, this rate of decline is projected to increase to 30-49% over the next 10 years (three generations), primarily due to habitat loss and hunting in its stronghold of Guatemala as a result of human population increases and opencast mining (Eitniear and Eisermann 2009, K. Eisermann in litt. 2010).
