What Do We Do

The IUCN-SSC Crocodile Specialist Group (CSG) is a worldwide network of biologists, wildlife managers, government officials, independent researchers, non-government (NGO) representatives, farmers, traders, tanners, fashion leaders, and private companies actively involved in the conservation of the world's 23 living species of alligators, crocodiles, caimans and gharials in the wild.

Latest News and Information

"Species of the Year 2021"

The Zoological Society for Species and Population Conservation (ZGAP) has chosen endangered crocodilians as "Species of the Year 2021", a campaign that is aimed at raising awareness of the threats and conservation needs of lesser-known wildlife species kept in zoos, and raising funds for conservation projects. During the year-long campaign, German-speaking zoos will be engaged in lobbying activities for three crocodile species, and raising funds to support three in-situ conservation projects:

•  Cuban crocodile in Zapata Swamp - Global Wildlife Conservation
•  Philippine crocodile on Siargao Island, Philippines - Crocodylus Porosus Philippines Inc.
•  Siamese crocodile in Kalimantan, Indonesia - Yayasan Kolaborasi Inklusi Konservasi

8th Charotar Crocodile Count

The 8th Charotar Crocodile Count report (January 2021) is now available. Anirudh Vasava also advised on the recent launch of an online citizen science portal to collect information on the three crocodilian species in India. Improvements to the portal's graphics and visualizations will be ongoing.

The Gharial Library Is Online

The Gharial Library is now online. It builds on the now discontinued Gharial Information Database, and is an ongoing attempt to compile relevant information to assist Gharial research and conservation. The library currently includes over 1300 references from the year 1756 onwards, and is a work in progress and will continue to be updated.

Feedback on missing publications, incorrect information, take-down requests, etc., can be directed to: gharial.info@gmail.com.

"History of Crocodile Management in the Northern Territory of Australia:
A Conservation Success Story"

The history of crocodile management in the Northern Territory of Australia (NT) has been pulled together by Professor Grahame Webb into an easy-to-read booklet, which will be available very soon. The NT provides an interesting case study of how sustainable use has been successfully used to conserve a large predator, in this case the Saltwater crocodile (Crocodylus porosus). But the road to this success has not always been smooth, and Professor Webb discusses the past and current threats to this management program.

A summary has been extracted from this booklet, and can be downloaded here.


"Marginals": Caimans of the Atlantic Forest

In a recent CSG Newsletter [39(1): 13-14] we reported on the launching of "Marginals": Caimans of the Atlantic Forest (in Portuguese and English) in November 2019. Projeto Caiman have made the book available as a downloadable pdf. Hard-cover copies can be ordered by e-mail (yhuri@institutomarcosdaniel.org.br; marcelo@institutomarcosdaniel.org.br) or via WhatsApp (+55.27.988272334) - all proceeds from sales go directly to conservation activities of Projeto Caiman.


With the postponement of the 26th CSG Working Meeting and the Drone Workshop until May 2021, we wish to avoid having CSG members miss out on information that could potentially assist their research, management and conservation efforts in the interim. To that end, and in keeping with our original goal of establishing an Unmanned Aircraft Systems (UAS) community of practice within the CSG, we are providing a range of resources here. We intend for this to be an open and interactive forum, and we encourage submissions and input from participants.


Diseases and Pathology of Reptiles, Volumes 1 and 2

Some 13 years have passed since the publication of “Infectious Diseases and Pathology of Reptiles: An Atlas and Text” in 2007. Since that time, a wealth of new information concerning the pathology and diseases of reptiles has been published. Elliott Jacobson (University of Florida) and Michael Garner (Northwest ZooPath) have joined forces to compile “Infectious Diseases and Pathology of Reptiles: Color Atlas and Text (Volume 1)” and “Noninfectious Diseases and Pathology of Reptiles: Color Atlas and Text (Volume 2)”. A brief summary of contents will be provided in the July-September 2020 issue of the CSG Newsletter. For anyone with an interest in diseases of reptiles, including crocodilians, these two volumes provide an updated review of a diversity of subjects.


Both volumes are now available from CRC Press and Amazon.


Building Public Awareness of New Hunting Regulations in Madagascar

The Madagascar Crocodile Conservation and Sustainable Use Program (MCCSUP), launched in 2014 in collaboration with the Malagasy CITES Management Authority, to assist Madagascar to improve crocodile conservation and management, recently released some public education materials to raise public awareness on new hunting regulations. A colouring book was produced for distribution to schools, a poster was developed highlighting the hunting regulations, and a cartoon-style film developed for television. The short film features local dialect, music, folklore and wildlife (view film). CSG Newsletter 39(2) contains more details on this initiative.

Conference Cycle on Crocodilians in the Latin America and the Caribbean Region

The CSG Latin America and Caribbean regional office has organised a series of virtual conferences to strengthen and expand communication amongst CSG members, students, etc., in the region, and promote discussion on issues on crocodilian conservation, research and management of crocodilians. The first presentation was on 21 April, and the series will continue until further notice.

Participants can easily log in and watch live presentations on the LAC Facebook page, or watch the taped sessions later on the LAC Facebook page or LAC Youtube channel. Although presented in Spanish, the majority of Powerpoint presentations are in English, allowing non-Spanish speakers to follow the themes.

"Seven Days on the Santee Delta"

santee-delta Long-time CSG member and wildlife biologist Phil Wilkinson has joined with award-winning environmental writer and Wofford College professor John Lane to co-author “Seven Days on the Santee Delta”. The book traces Phil’s life against the backdrop of coastal South Carolina and the Santee Delta - the largest river delta on the eastern seaboard of the USA.

Georgetown native Phil grew up on Hopsewee Plantation on the North Santee River, and knows the Santee Delta with the intensity of time. The book is beautifully illustrated with Phil’s photographs of the delta’s people, wildlife, etc., and combined with his homespun stories, “Seven Days on the Santee Delta” makes for an amazing read. It is good to see that the Lord Berkeley Conservation Trust and Evening Post Books have managed to bring Phil Wilkinson’s legacy to a wider public audience.


New Book on Alligators!

Dr. Kent Vliet, another long-time CSG member, has put together a richly illustrated account of the biology, behaviour and conservation of the American alligator. With over 150 photographs from wildlife photographer Wayne Lynch, through “Alligators - the Illustrated Guide to their Biology, Behavior, and Conservation” (Johns Hopkins Press, 304 pp, 2020), Kent introduces readers to one of the world’s most recognised crocodilians.

The book combines Kent’s captivating storytelling with current scientific knowledge on the species, from its anatomy and physiology, to its complex social life. It will be a valuable addition to anyone’s collection, and especially for those interested and/or working with crocodilians.
