Status of Nile Crocodile in North Eastern KwaZulu-Natal and conservation management recommendations
Expanded Title:The concurrent research of Nile Crocodiles in Lake St Lucia, NGR and Pongolapoort Dam showed how these differed in their ecology and human pressures so affecting the Nile Crocodiles in different ways and illustrating that “one shoe does not fit all”.The study revealed numerous novel insights into the ecology, behaviour and health of Nile Crocodiles in KwaZulu-Natal, South Africa, and some of the findings may be applicable to other crocodilian taxa. We hope the results will guide the management and conservation of this threatened species and the water-bodies they are associated with. There are concerns about protection of nesting sites, increased anthropogenic disturbance, illegal poaching of crocodiles, and human wildlife conflict. There is an urgent need for ecological, behaviour and health research of Nile Crocodile populations in Kosi Bay, Lake Sibaya and Hluhluwe-Imfolozi Park. Furthermore, the population declines in, especially, unfenced populations such as Kosi Bay and Lake Sibaya are driven by illegal killings for Nile Crocodile body parts, blood and fat. We need to understand the trade in Nile Crocodile products and neighbouring local people’s attitude, behaviours and perceptions of Nile Crocodiles, in order to formulate effective conservation programmes for Nile Crocodiles in KwaZulu-Natal. In particular the following recommendations need to be implemented at all study sites for Nile Crocodile conservation: • Continuation of annual Nile crocodile aerial surveys • Continuation of annual Nile crocodile nesting surveys • Limiting anthropogenic disturbance especially destruction of riverine vegetation from unsuitable agricultural activities and the resultant destruction of nesting sites • Limiting competition for food resources • Prevention of illegal poaching of live crocodiles • Reduction of human wildlife conflict • Reduction in use of led sinkers by fishermen to prevent lead poisoning of crocodiles.
