In this rich Brazilian biome, subtle changes in relief and hydrological condition change soil properties, and affect the distribution of the highly diverse flora and fauna. The wetland soils of Pantanal are closely related to the nature of sediments, and vary according to changes in erosion and deposition/sedimentation rates. Depending on the amount of sand, primary minerals and watertable level, many different types of soils are formed. Quaternary Climatic changes associated with various glacial/interglacial periods occurred in the region, allowing changing pedoclimates with contrasting soil formation processes. The pedoenvironments and soils present in the Pantanal subregions strongly vary according to small topographical variations. Altimetric differences, even a few centimeters, have great influence in soil formation, determining the flood and drought periods at different parts of the landscape. Some soil characteristics also influence the internal flow of water, both vertical and lateral. These differences result in varying intensities of hydromorphism, present in all soils of Pantanal. Even at the highest landscape, soils show signs of hydromorphism, identified by the presence of grayish colors, and Fe3+ reduction process. Paludization, gleying, laterization (plinthite formation), solodization, salinization, argilluviation and podzolization are common pedogenic processes in Pantanal, and are strongly driven by the flooding regime. The main soils in Pantanal are (in decreasing order of total area): Planossolos Nátricos (23%) &gt Plintossolos (21%) &gt Espodossolos Ferrilúvicos (19%) &gt Planossolos Háplicos (11,8%) &gt Gleissolos (11,7%) &gt Vertissolos (5,8%) &gt Argissolos Vermelho-Amarelos (4,8%) &gt Other minor soils (Neossolos Litólicos, Neossolos Quartzarênicos, Chernossolos Argilúvicos, Neossolos Flúvicos, all with less than 5% in total). The Pantanal wetlands, one of the richest biomes in the neotropics, are under severe threat of vegetation loss and widespread burning due to the intensification of land use, with replacement of the traditional cattle ranching, and climate changes.  aPantanal  aSolo1 aCORRÊA, G.
