World Lemur Day is observed worldwide on the last Friday of October to highlight the conservation needs of lemurs, which are primarily found in Madagascar. Established in 2014 by Professor Jonah Ratsimbazafy of GERP Madagascar, the day aims to address the threats of extinction faced by lemurs, with events organized globally by zoos, conservation organizations, and individuals. The day coincides with the World Lemur Festival, which includes various educational and conservation activities. Participants can engage by visiting local zoos, attending events, or organizing their own activities to promote lemur conservation. The International Union for Conservation of Nature (IUCN) classifies most lemur species as threatened, with habitat destruction being a significant threat. Conservation efforts in Madagascar, including the establishment of protected areas and community-based programs by organizations like the Duke Lemur Center, play a crucial role in supporting lemur populations.
