About us

Who we are

At Polonnaruwa we operate the “Primate Center Lodge” known locally also as the “Monkey Camp”.  This facility serves to accommodate guests and research personnel.  It is also known formally as the “Smithsonian Primate Research Station” (e.g., on the Google map).  We are the Association for the Conservation of Primate Diversity, under the umbrella of the Smithsonian Institution Primate Biology Program, based in Sri Lanka and the USA. Our studies on the monkeys have been highlighted recently in the movie theater film “Monkey Kingdom” (produced with Disney Nature).  Our work also has been featured in many documentary films for TV on the BBC, Discovery, Animal Planet and others.  We publish our new research discoveries regularly in scientific journals and the popular media.

We have the following affiliations:

  • The Association for the Conservation of Primate Diversity (ACPD) is registered as a non-profit company in Sri Lanka. It can accept donations, or market for the support of conservation, research and education efforts.
  • We are affiliated with the National Institute of Fundamental Studies, Sri Lanka, where Dr. Dittus is a Visiting Senior Fellow and leader of the Primate Biology Project. We do collaborative research with the Faculty of Veterinary Medicine and Animal Health at the University of Peradeniya and others.  Learn more
  • Dr. Dittus is a Research Associate of the Smithsonian Conservation Biology Institute and the Conservation Ecology Center, in Washington, DC, USA.  Learn more

Mission Statement

We advance scientific knowledge for conserving wildlife, and for a better understanding of the evolution of primate society and man’s place in nature.

We have dedicated over 47 years to the comprehensive research of wild primate populations. Working locally at Polonnaruwa, Sri Lanka, our educational reach is global through publications, documentary films and other programs. We teach and inspire people to appreciate wildlife, particularly primates, and their habitats and to protect them. We practice conservation leadership in all we do.
