Mr Charlie MANOLIS
Co-Chair
After graduating from the University of New South Wales in 1980, Charlie Manolis began working with Grahame Webb on crocodiles in northern Australia. Conservation and management were the primary focus of activities in the 1980s, but these diversified in the late 1980s and 1990s, by which time crocodile populations were expanding rapidly. Sustainable use of wildlife was adopted as a conservation tool, which allowed the public to tolerate the recovery of Saltwater crocodiles. Charlie Manolis was invited to become a CSG member in 1988, and in 2018 he took on the role of Deputy Chair. Since 2004 he has been editor and compiler of the Crocodile Specialist Group Newsletter, a key communication tool for the CSG. His involvement and publications on crocodilians have covered many aspects of research, management, conservation, including farming and production, welfare and training.

More about the Specialist Group
The IUCN SSC Crocodile Specialist Group (CSG) is to assist the International Union for Conservation of Nature (IUCN) and the Species Survival Commission (SSC) to meet their missions with regard to the conservation, management and sustainable use of world crocodilians.
The key to this success is the cooperation of companies involved in the international reptile skin and leather trade, crocodilian farmers and ranchers, skin traders, tanners, manufacturers ...
MISSION
Assist the International Union for Conservation of Nature (IUCN) and the Species Survival Commissions (SSC) to meet their missions with regard to the conservation, management and sustainable use of world crocodilians.
Specialist Group work
By the end of 2025, we envisage: (1) increased reintroductions and improved status of wild populations of Critically Endangered crocodilian species such as Alligator sinensis (China), Crocodylus siamensis (Cambodia, Thailand, Vietnam, Laos) and Crocodylus mindorensis (Philippines); (2) improved legal protection status of C. siamensis and Tomistoma schlegelii habitat in Lake Mesangat, East Kalimantan, Indonesia; (3) tracking study implemented on T. schlegelii; (4) publications on traceability systems, sustainable use and livelihoods and Conservation Priorities; (5) completion of species Action Plans; and, (6) develop a standard reference source for crocodilians.
Understanding threats to Crocodiles
The CSG network of experts advises governments and wildlife management agencies, evaluates the conservation needs of crocodilian populations, initiates research projects, conducts surveys of wild populations, provides technical information and training, initiates conservation programs, etc. The CSG’s administrative and publishing budget is raised almost entirely from private donations.
Crocodiles on the IUCN Red List
The Red List is used as a guide by the CSG to prioritize its work, but it also relies on a suite of other information when evaluating issues requiring specific action. For example, information from CSG members, NGOs and wildlife authorities is vital to directing the CSG’s efforts. Efforts to re-establish international trade on a legal and sustainable basis have clearly assisted the recovery of many crocodilian species, but some will require ongoing efforts.
