About The Primatalogical Society of Sri Lanka
The Primatological Society of Sri Lanka (PSSL) serves as a platform for professionals dedicated to primatology and primate conservation within the country. It brings together primate experts, their teams, and affiliated networks actively involved in various aspects of primate research and conservation. These include research on primates and their habitats- encompassing vegetation analysis, and cutting-edge techniques such as use of geographic information systems (GIS) and remote sensing, paving the way for more effective species and habitat conservation strategies. The PSSL also focuses on habitat conservation, mitigating human-monkey conflict; education and awareness initiatives; and fostering collaborations with local communities, the general public, and overseas primate experts. At the heart of the PSSL lies a community of experts on the different species of primates in Sri Lanka. It acts as a harmonious gathering place, bringing together like-minded individuals and their remarkable teams who work to unravel the mysteries of primates and protect their precious habitats. It is a group where ideas can be exchanged and collaborations can flourish to provide support for any national issue or activity that will help conserve primates and reduce human-monkey conflict. The society’s members delve deep into varied aspects of primate research that extend beyond the behaviour and ecology of these fascinating animals and conservation of their habitats, to community participation for habitat conservation, and garbage management. The members of the society strive to ensure that future generations will be able to enjoy the diverse array of primate species that call Sri Lanka home, and build a younger generation of local primatologists who will study these primates in their Sri Lankan habitats. The Primatological Society of Sri Lanka aims to embody the indomitable spirit of individuals united by a common cause to leave an indelible mark on the landscape of primate research and conservation in Sri Lanka. With an unwavering commitment to preserve and safeguard primate habitats, the Society stands as an advocate for primate and habitat conservation and for ethical and authentic primate research.
Our society is committed to:
a. Facilitate conservation and welfare of non-human primates
b. Promote education & awareness about non-human primates
c. Help resolve the human-monkey conflict
d. Provide opportunities for young people to experience and appreciate non-human primates in their natural habitats
e. Facilitate high quality field research on non-human primates and their habitats
f. Promote high quality publications and communication on non-human primates
g. Create links between local and international efforts for primate conservation
h. Enable capacity building to conserve and manage non-human primates and their natural habitats
We hope you will join the efforts of PSSL

Dr Jinie Dela
President of Primatalogical Society of Sri Lanka
Dr Jinie Dela is the present President of the Primatological Society of Sri Lanka. She has long-term expertise on primate conservation and research since she commenced her pioneering doctoral work in 1985 on the behaviour and ecology of the Critically Endangered western purple-faced langur of Sir Lanka. She is now working on a self-sustaining field project to conserve the WPFL and its habitats (jointly with the Forest Department, colleagues and community) through novel approaches to manage fragmented small forests by forming ecological networks within larger landscapes. She was advisor for the initiative of the National Man and the Biosphere Committee of Sri Lanka to prepare a framework to address monkey–human conflict in the country. Dr Dela brings to her primate work her long-term professional expertise in biodiversity conservation, World Heritage Sites and Biosphere Reserves, climate change, species red listing, policy planning, strategic communication planning, preparation of landscape management plans and nature-based tourism plans. She was Team Leader for preparation of the 2030 National Biodiversity Targets for Sri Lanka. Her professional work spans the National Science Foundation (NSF) and IUCN Sri Lanka, and later as a freelance consultant and volunteer in the varied roles of technical expert, educator, teacher, consultant, and communicator, both nationally and internationally. She was a visiting academic at the Open University of Sri Lanka, and the Universities of Peradeniya and Moratuwa. She is a member of the Sri Lanka National Experts Committee on Biological Diversity and Secretary of the National Man and the Biosphere Committee hosted by NSF-SL. She plays the piano and loves reading, cooking, interior decorating and watching classical ballet.

Dr W.P.J. Dittus
Scientific Advisor
Through the Smithsonian Primate Biology Program (Sri Lanka) he aims to advance scientific knowledge for better understanding of the evolution of primate society and man’s place in nature, as well as for conserving wildlife. It provides insights of the many-sided nature of primate adaptations and the environmental context in which they evolved. The studies involve many collaborators from different disciplines, and have been ongoing continuously for over 54 years at a site of natural dry evergreen forest, the Polonnaruwa Nature Sanctuary and Archaeological Reserve, in the dry zone of Sri Lanka. Studies span the four sympatric primates there: Toque Macaque (Macaca sinica), Gray Langur (Semnopithecus priam), Purple-faced Langur (S. vetulus), and Slender Loris (Loris lydekkerianus); and these species’ demography (births, deaths, emigrations) in relation to social behavior, ecology, environment, and other facets of life are monitored. Published topics include behavioral ecology, growth and development, morphology, population genetics, paternity, social behavior, vocal communication, forest ecology, epidemiology, physiology, and conservation among others. New scientific discoveries feature in publications, and outreach educational programs to local schools and institutions. More than 40 documentary films based on the studies reach global audiences and includes the movie theater film “Monkey Kingdom” (produced with Disney Nature), as well many TV productions on the BBC, Discovery, Animal Planet, Smithsonian Channel, Rupavahini, and others. To promote the programmer’s aims, Dr Dittus and colleagues have established a non-profit company, the Association for the Conservation of Primate Diversity.
