Anthropic actions such as the removal of native vegetation cause the soil infiltration processes to be modified in the semiarid region. The objective of this research was to evaluate the infiltration capacity of the soil in different vegetation coverings in the semiarid region of Pernambuco, Brazil. The evaluation of the different infiltration capacities were carried out using concentric cylinder infiltrometer in three treatments: T1 - without vegetation cover, T2 - soil covered with litter, T3 - soil covered with native vegetation of caatinga and the estimates with the models of Horton and Kostiakov. Among the treatments studied, the soil covered by native vegetation of semi-shrubby caatinga, showed the highest infiltration capacity and basic infiltration speed. The substitution of native vegetation reflected in significant differences between treatments, soil without cover and soil with litter, both with the soil class Neossolos Flúvicos. Among the models analyzed, Horton's showed the best adjustment of the estimated values regarding the infiltration rate.
