Globally, feral pigs (Sus scrofa) haves proven to be a highly invasive species able to generate strong effects on natural ecosystems. In Colombia, pigs were introduced in the sixteenth century and today they are part of livestock production within the country under technical standards. However, in several rural areas of the country, there is a rustic management of domestic swine, which has facilitated the process of feralization, ie, the formation of feral populations that co-exist with wildlife. One of the regions where this process is ongoing is the Colombian Orinoco, where it is common for pigs to be released around farms. Although it is common to observe feral pig populations in this region, and that there are advances in their study, it is relevant to provide new information on their abundance and habitat use. The purpose of this study sought to better understand the distribution, density and habitat use of the feral pig at the municipality of Paz de Ariporo, Casanare. Individuals counts were done using the line transect, recording the perpendicular distance to the transect, groups composition and types of vegetation where the animals were. Additionally, surveys were made in the region for the distribution of feral pigs and other records were obtained from previous work in the area to model the potential distribution of pigs in the department of Casanare. A density of 10,615 ind / km2 was obtained, showing a preference for habitats associated with water bodies (estuary and gallery forests). Potential distribution covers about 7 of the 19 municipalities of the department. Several climate and habitat factors were associated with distribution. The populations of feral pigs in Casanare reflect their quality of being a ubiquitous and highly adaptable species.
