Three new wetlands inventories in brazil

The inventories of wetlands provide an indication of the location of the land with the highest biological diversity. In Brazil, studies of wetlands stressing the inventory and classification are scarce and three recent inventories have been developed. The establishment of a wetland national inventory in Brazil is necessary and could be started in the semiarid region because of the small amount of surface water and non-complexity of aquatic ecosystems. The wetlands inventory and classification must be encouraged in Brazil. The classification structure should be composed by different levels arranged in an hierarchical fashion. However, Brazil has a long way to go, since basic research related to the wetlands inventory and classification have not been investigated by Brazilian researchers.
