Abstract

This work was carried out on Nhumirim farm, owned by Embrapa Pantanal, in Nhecolândia region, Pantanal (wetlands) of Mato Grosso do Sul State. In Nhecolândia the natural environment conditions, mainly floods and rainfall have been influenced vegetation dynamics. In other hand, Nhecolândia is one of the most significant beef cattle raising regions in Brazil, and recognizing a habitual annual calendar of floods and rainfall is important to spatial and temporal use of these pastures by cattle for conservation and sustainable usage of this natural resources. This work suggest a calendar of floods/ wetness of the soil and rainfall that was established according usually drought or wet throughout the years and monthly periods, considering soils, rain falls, topography and vegetation units. The methodology of this work was based on fieldwork, interpretation of satellite images of Landsat-7, climatic classifications of the humidity of the months and years, considering the period of 1977 to 2005.
