Special Reports

The PSG also produces and contributes to special surveys and other publications, the most widely recognized of which is the Top 25 list of the world's most endangered primates. First introduced as a media outreach tool in 2000, the Top 25 list has become a biannual review of those species and subspecies in the direst need — some of whom now survive only as a few dozen individuals. By highlighting the danger to a selected few, the PSG hopes to draw attention to the wider issues of primate conservation, and to help the public empathize with individual species. Only those primates designated as Critically Endangered are considered for inclusion on the Top 25, but many of the taxa featured in previous editions have directly benefited from the human awareness encouraged by the list.

The most recent edition of the Top 25 list is available as a report in PDF; this version was revised in July 2006 at the 21st Congress of the International Primatological Society in Uganda. The Top 25 list will be revisited in a special session of the 22nd IPS Congress in Scotland in 2008. The Top 25 report is also available in its own section here on the PSG website, and we encourage you to explore.
