The establishment of cultivated pastures is the main cause of deforestation in the Brazilian Amazon. In Acre, cultivated pastures represent ８2,5％ of the total area deforested. Since 1994, farmers in the Brazilian Amazon started to observe the death of marandugrass (Brachiaria brizantha) in some pastures under poorly‐drained soils, a process that have caused widespread degradation of pastures in the region. The objective of this study was to define zones of risks of death of marandugrass as a support decision tool for policymakers and farmers in dealing with this problem in the Brazilian Amazon .
