Silvipastoral systems on Amazon river jloodplains: identification of multipurpose forestspecies based on traditional knowledge of riverside inhabitantsThe floodplains along the Amazon River and tributaries, in the Lower Amazon Region,State of Pará, Brazil, are characterized by a hot and humid climate and by annualflooding oftheir banks. This floodplain system is highly specific, with its use essentiallybased on ecological management. However, agriculture followed by ranching has led toa reduction of tree cover, which aIters the characteristics of that ecosystem. Traditionalpopulations make use of a significant part of natural resources in gallery forest, whereextractivism has proven itself strategic in terms of maintaining sustainability.Nonetheless, with the floodplain areas deforested, those populations find themselvesdeprived of important sources of food and other uses. Recuperating the ecosystem byintroducing trees into pastures (silvipastoral systems) represents not only a sustainableaIternative but also a cultural challenge due to regional traditions, which are a stronginheritance from older practices. Given that understanding on human perception bylocal populations is vital for planning and implementing sustainable practices, aparticipatory diagnosis was carried out, seeking to recover this traditional knowledgerelated to forest resources and their use in these periodically flooded areas. Thediagnosis recorded 21 species consumed by humans, domestic and wild animais andfish, under different forms of use. The grouping analysis brought together the forestspecies cited by producers and placed them into five groups according to use: 1) fruittrees predominantly for human use (Inga edulis, Spondias mombin, Piranhea trifoliata,Lecythis Pisonis camb., Crescentia cuiete); 2) fruit trees that are widely used byhumans, domestic and wild animais and fish (Platonia insignis, Eugenia brachypoda,Genipa americana); 3) fruit trees used by wild animais and fish, considered a groupwith an ecological function (Crataeva benthamii, Cordia tetrandra, Ficus sp,Astrocaryum jauari, Bombax munguba, Couroupita guianenses); 4) forest species formultiple timber use, focused on use ofwood and bark by humans (Cecropia sp, Andirainermis, Corallodendron fuscum, Hura crepitansy; 5) forest species with a timber focusand specific use by humans (Schizolobium amazonicum, Tachigalia paniculata,Pentaclethra macrolaba).
