Community Participation in Conservation and Management of Crocodiles through the Egg Harvest Program in the Sepik Region of Papua New Guinea Robert Sine 1 , David Wilkins 2 and Godfrid C Solmu 2 1 Department of Environment and Conservation, P.O. Box 6601, BOROKO, NCD 111, Papua New Guinea 2 Mainland Holdings Limited, P.O Box 196, LAE, Morobe Province, Papua New Guinea ABSTRACT: The core aspect of the crocodile management program in Papua New Guinea depends heavily on sustainable utilization of wild resources. Over the last 40 years the program has progressed through four distinct phases. Initially from direct wild harvest to controlled harvest of size limits, then came the capture of small juveniles for ranching operations, and lately the harvest of wild eggs. Therefore the wild harvest of skins, juveniles and egg increases the benefit to resources owners and add value to facilitate and strengthen the approaches to habitat conservation and management of wild crocodile resources. The current egg harvest program implemented by Mainland Holdings, Department of Environment and Conservation, and the Sepik Wetlands Management Initiative provides direct benefits to resource owners who realize the importance of crocodile habitat conservation. INTRODUCTION The vast wetland areas of Papua New Guinea is inhabited by two species of crocodiles, the New Guinea fresh water crocodile, Crocodylus novaeguineae, and Crocodylus porosus commonly known as the saltwater crocodile. C. novaeguineae is endemic to the mainland of New Guinea including Irian Jaya while C. porosus is found on both the mainland and the offshore surrounding island of Papua New Guinea. (Figure 1).
