What are the EEP roles?
The Invasive marmoset EEP oversees the common marmoset (Callithrix jacchus), listed as Least Concern on the IUCN Red List. With the ever-growing threats to callitrichid species in the wild and the need to build up ex situ insurance populations, both in the range country and internationally, these species are being actively phased out by the EAZA Callitrichid TAG. All individuals have a non-breeding recommendation.
| General education |
| Exhibit |
| The ex situ population should be used to educate visitors about callitrichid biology, ecology, and conservation. Additionally, the species can be used to teach visitors about why wild animals are not suitable pets. |
| Until phase out, the EAZA population should be used to maintain knowledge and gain husbandry experience on mixed-species exhibits, which can then be used to keep callitrichid species with a conservation concern and conservation roles. |
