Eight species belonging to Muridae and Viverridae family were documented and collected in the three sampling sites: Polomolok, South Cotabato; Upper Biangan, Malungon, Sarangani Province and; K’laja, Conel, General Santos City. Philippines contain unique small non-volant fauna, which can be seen in greater Mindanao, the second largest island of the country, that has not yet been studied that much and still lacks information predominantly on areas like South Cotabato, Sarangani and General Santos City. This study was conducted to determine the different species found in three sampling sites on agricultural landscapes in selected areas of SOCCSKSARGEN. Sampling was done on October – December of 2015 using baited Sherman trap cages that were set through the three sampling sites. Species Rattus everetti was the dominant and most abundant group along the three sites. Species diversity is low as well as endemism; furthermore, there is observed much significant difference in species evenness and species richness. However, the study provides vital information about the current diversity of small non-volant mammals residing on certain parts of SOCCSKSARGEN region.
