In Burkina Faso, human activities are practiced in Nazinga Game Ranch (NGR) which is colonized by West African crocodiles Crocodylus suchus (Geoffroy Saint-Hilaire 1807) decades ago. This study aims to estimate impact of anthropogenic on abundance C. has been conducted NGR reservoirs. For data collection, populations were counted morning, afternoon and night from October 2015 May 2017 11 Binoculars used for remote observations spotlight was night. According the size sites its accessibility, direct carried out foot or canoe. Every time we observed crocodiles, they numbered added information such as their size, behavior, geographical coordinates type habitat collected. Human noted after observations. The R software version 3.5.3 analysis. A total 1849 including hatchlings, juveniles, subadults adults these reservoirs NGR.
