The study of climate change is done based in present models that are used as a parameter for the past. The most used model confronts field x forest, however this model can´t be used for the Pampa biome where occurs mainly countryside conditions. In search of a more suitable model for the Pampa biome, and seeking to raise the accuracy of obtained results by palynology, pollen material of Dyckia species will be collected and processed by the acetolysis method to make the slides and catalogues. Among the species processed, 8 were analysed, being measured in polar view (PV) and equatorial view (LV) and classified morphologically. The diversity of pollen morphology found in the analysed species will enrich the Pollen collection, contributing to a better design of past vegetation panoramas, as it provides comparative data with this environment.
