Draft Management Program for the Saltwater Crocodile in the Northern Territory 23 can be targeted for more frequent and active surveillance. Such a risk analysis will allow the areas that require new or increased management interventions and the nature and scale of that management response to be identified and targeted. There will be only a very limited range of circumstances where crocodile densities can be reduced to near zero and effectively no circumstances where the density can be guaranteed to be zero. The only safe assumption is that any body of water in the Top End may contain large and potentially dangerous crocodiles. Many waterways that are isolated in the dry season are connected to other river systems during the wet season, allowing crocodiles to move over a large area. The common name of Saltwater Crocodile is something of a misnomer and perhaps creates some misconceptions that the species is confined to saltwater/estuarine habitats. Saltwater Crocodiles have always been found not only in coastal and tidal rivers, but also in floodplains, billabongs, and freshwater streams and habitats hundreds of kilometres inland. The expanding crocodile population also means that animals are turning up in areas where they have not been seen for many years. Performance Indicators Analyse the risk of areas where human interaction with crocodiles may occur and prepare options for the appropriate level of management options. Analyse nuisance crocodile capture data to assess trends and identify areas of increasing risk to humans. Develop and implement a Living with Crocodiles strategy to educate and heighten the awareness of the dangers of crocodiles in the Northern Territorys waterways. 4.4 Removal of nuisance crocodiles The program allows for nuisance Saltwater Crocodiles to be killed and used directly for skin and meat production, or captured and used as stock in crocodile farms. Crocodiles are not relocated because they often return to the point of capture and because of the expense of transport and handling. The Northern Territory Government has specialist staff-members who remove nuisance crocodiles. These crocodiles are purchased by crocodile farms. In remote areas where Northern Territory Government staff-members are unable to attend, crocodiles may be removed following the issue of a permit to take by the Northern Territory Government. Crocodiles taken in these circumstances will be counted against the ceiling for wild harvest. Nuisance crocodiles removed by the Northern Territory Government staff are not counted against the ceiling for wild harvested crocodiles. A number of areas in the Top End are designated No Tolerance zones and culling is carried out to maintain these areas crocodile-free (Table 4). Darwin Harbour and the Katherine River have defined zones and specific management actions to remove crocodiles. The current Darwin Harbour Crocodile Management Area extends from Charles Point to the west to Tree Point to the east including Darwin Harbour, Shoal Bay and their estuaries. The existing level of control based largely on permanent traps and spotlight surveillance will be maintained. Additionally, due to increasing residential living in the Darwin rural area, an expanded Darwin Crocodile Management Zone will be established and will include identified high risk areas in the entire Darwin Harbour catchment and eastwards to the Adelaide River (Figure 4).
