The aim of this study was to compare the use made by peccaries (Pecari tajacu) in relation to the type of forest cover, the primary forest and secondary forest at the Biological Station "La Selva" of Costa Rica. In each type of forest cover was made: saíno counting footprints along the trails, and 25 plots were established to measure the removal of litter, and the consumption of fruits and plants of the species. In the secondary forest was observed an average of 5.34 tracks / km (SD = 1.65) and in seven plots were found litter removal. In the primary forest footprints were observed 6.82 / km (SD = 7.93), eight plots with litter removal and one with fruit consumption signals. No significant differences in habitat use.
