To maintain its role of biodiversity conservation and of generating incomes to the local Community, Nazinga Game Ranch has created since 1981 an annual monitoring device of wildlife based on distance sampling method.  Each year, wildlife census was conducted and   data on observed animal and threats are collected on linear transects.  These data are of great interest for sustainable management of wildlife populations in Nazinga Game Ranch.  However there was no structured system where data can be well organized for quick and effective management decision.  The database creation based on annual wildlife census in Nazinga Game Ranch was a wonderful tool that can facilitate the spatial analysis of animal species and anthropogenic disturbance as well. In this study we have constructed a model based on the distance sampling method and the wildlife census device existing in Nazinga Game Ranch.  From the information analysis, a total of 11 entities and 7 associations were proposed in the conceptual model and then 16 tables and 74 fields was generated in the physical model and implemented in Microsoft ACCESS.   Character corresponding to each field was set to allow a good coordination between data. This tool allows also the request of perpendicular distance which is an important variable for density and abundance estimation in Distance programme.  It can also generate directly geographical data to be exported for visualization in GIS software and allowing the study of spatial distribution of animal species and analyzing whether animal movements are driven by resources availability or threats locations.  Five years data (from 2004 to 2009) were recorded in the database and can be used to assess the evolution and the population dynamic of wildlife species within the protected area.  In addition data on anthropogenic disturbance can be easily visualized and lead to enhancing the protection strategy and the development of the management plan of the protected area.
