In January 2007, HALI Project team members met with Tanzania National Parks (TANAPA) veterinarians to explore linkages between the HALI project objectives and TANAPA's goals for wildlife health monitoring inside Ruaha National Park (RNP). Based on discussions, the HALI project submitted a formal request to the TANAPA Director General to immobilize a sample of wild animals in RNP. The immobilization effort would be conducted by TANAPA veterinarians and RNP staff with financial and logistical support from the HALI Project. The HALI Project will provide TANAPA vet with the veterinary drugs, immobilization equipment (rifles, darts and additional veterinary supplies), vehicles and other logistical supplies needed to accomplish the work. Furthermore, additional veterinary support from Sokoine University of Agriculture (SUA) and HALI Project veterinarians will be provided, and the activities are proposed such that they would serve as valuable training for TANAPA staff and SUA students. The proposed TANAPA immobilization activity addresses TANAPA vets' goal of conducting increased disease surveillance in RNP, an area for which little information is currently known. Lack of training, low funding, scant equipment and lack of local veterinary facilities has hindered TANAPA's capacity to investigate wildlife health issues. Support from the HALI project will increase the number of diseases being evaluated, enable TANAPA to carry out rinderpest surveillance and facilitate handling additional animals (at no cost to TANAPA). Furthermore, integration of data from Ruaha with data currently being collected by the HALI Project outside the park will allow a comprehensive assessment of disease risks at the ecosystem level. This information can be used by TANAPA and other wildlife agencies in Tanzania to help address disease threats at the wildlife/livestock interface.
