In the region of Cariri Ceara, the natural singularities, especially in the areas of direct influence of Araripe Plateau, reaffirm their exception character within the semi-arid region of northeastern Brazil and define the palm swamps as exception subspaces. In this article, we seek to present the natural characteristics of the palm swamps of the Araripe Plateau, which are possess Hyperdystric Umbric Subaquatic Gleysols (WRB, 2014), acid, very weathered, with predominance of negative charges. These soils support burins, among other freatophytes, which are heritage of a complex paleoecologica and paleoclimate evolution, maintained today by the influences of the exudation zones. The palm swamps of the Araripe Plateau are classified from the geomorpholocial point of view, belonging to 4 (four) specific types: Patamar, Chapaddo drepression, foothill and hillside, they form at these topographic positions due to the water table depth, having its evolutionary process related to the erosion and escarpment recoil. The palm swamps of the Araripe Plateau are currently refuges and strained by the semiarid climate.
