%X The Pantanal is the largest tropical wetland and is located in the center of South America. It corresponds to an active sedimentary basin of Quaternary age with an area about 160,000 km2. Despite the monotony of terrigenous sediments, deposited by several megafans, its vegetation present high variability. This variability is a result of many factors: the region being surrounded by four biomes (Brazillian savanna, Chaco, Amazon Rainforest and Atlantic Forest), the flood pulse, the geological history, expressed by the variability in the sediment source areas and neotectonics and the flatness of the area. Small variations in relief, between decimeters to a few meters, imply in changes in floods duration and intensity. Thus faults with small vertical reject can generate vegetation lineaments. This paper discusses the characterization of the most notable of these lineaments in the Pantanal, a feature with NE direction and about 100 km long, considering the similarity between the sample plots (using the Jaccard index - Jacc) and the bulk of plant phenological variability obtained remotely by MODIS NDVI timeseries. At the NW side of the studied lineament the vegetation is evergreen, while on the SE side the vegetation becomes dry during the long and severe annual droughts. Considering the Jacc of the plots, we can conclude that there are two regional strata. One at NW region of the lineament (Seasonally Flooded Evergreen Forests), and a second stratum, at SE mainly, characterized by Cordilheiras (paleolevees) and Cerradões. This stratum has various degrees of similarity between plots. The strata presented high floristic dissimilarity between them, what is clearly seen by their regional phenological behavior. Considering that is a flat region without critical variations of soils as well as the magnitude of the lineament, the results are really impressive.
