    This study presents a design of a Data-Driven software application for identification, population monitoring, and risk assessment for lions in Serengeti Tanzania. Lions’ populations have been declining due to poaching, overhunting, and other ecosystem factors resulting in unmet demands for tourism and ecological balance. Data-driven techniques can lower the negative consequences by providing mechanisms for lions’ management, risk assessment, and monitoring in selected wildlife reserves. Lion’s whisker spots, poaching rates, prey availability, human-conflict incidences, and pride size are key elements for achieving management, identification, monitoring, and risk assessment for lions. The software application design aimed at providing conceptual and logical requirements for the development of the application that will enhance lions’ monitoring and management efforts to protect their existence and contribution to the ecosystem. The study was conducted in the Serengeti ecosystem, including ecologists from the Tanzania Wildlife Research Institute Serengeti Wildlife Research Center, and information systems analysts. Through a mixed research methods approach, qualitative methods and incremental prototyping software development life cycle model were used to develop the specific requirements. Unified Modeling Language (UML) was used to model the requirements and led to the realization of design diagrams: application framework, database design, and artificial intelligence model workflows. The application should equip ecologists with tools to add and identify specific lions, monitor sightings, estimate population trends, assess risks for individual lions, and produce reports on monitoring and sightings. This design serves as a foundation for developing the data-driven software application for identification, population monitoring, and risk assessment for lions in Serengeti National Park Tanzania which will enhance monitoring and management activities of lions’ population non-invasively.

    Population size estimates and distribution of the African elephant using the dung surveys method in Rubondo Island National Park, Tanzania
    (International Journal of Biodiversity and Conservation, 2016-06) Mwambola, Simon; Ijumba, Jasper; Kibasa, Wickson; Masenga, Emmanuel; Eblate, Ernest; Munishi, Linus
    A study to estimate population size and distribution of elephants in the Rubondo Island National Park (RINP) was conducted between March and July 2014. It involved elephant dung survey methods. In estimating elephant dung pile density, a total of 217 dung piles were enumerated in 58 transects (each 1 km). The on-site dung decay rate computed from 100 marked fresh dung piles was estimated to be 0.01542 per day. By combining estimated dung pile density, on-site decay rate and defecation rate of 17 dung piles per day, the study found an estimate of about 102 elephants (95% CI, 72-144). Furthermore, results of this study indicate that, elephants were found to be more concentrated on the central and northern zones, which are the areas of the park that have some open glades allowing elephant to access the area easily to lake shores. The information generated from the study can be incorporated into setting up future management strategies for elephant conservation in RINP.
