As árvores nativas e o saber local como contribuição à sustentabilidade de agroecossistemas familiares na Serra dos Tapes, RS

Abstract

One of the most important strategies in the process of appropriation of nature by social groups for their survival, perpetuation and sustainability, is the identification of species of native trees and the recognition of their potential for different purposes. Much of this vast traditional knowledge associated with arboreal biodiversity has been lost over time. Along with the loss of such knowledge, we witnessed the degradation of forests. Faced with this alarming erosion of biological and cultural diversity, it is necessary to take steps to protect biodiversity, as well as rescuing traditional knowledge associated with it. This paper proposes the recovery strategies of appropriation and uses of 115 native species by 04 farmers of the Serra Tapes Rio Grande do Sul BrasilS, Brazil. For such semi-structured interviews over traditional identification methods and the uses assigned to these species by farmers were performed. For species identification was used material with photographic documentation and herbarium specimens. Farmers were shown to have considerable knowledge about native tree flora, recognizing, through the material, the majority of species, for which common names cited and attributed, mostly, different types of uses historically performed in agroecosystems. Still photographic documentation of all species was performed, detailing their bodies and useful identification characters. The data obtained are of great relevance for other work and, opening up a range of possibilities for research in various branches of science. The results of this research are still needed for the preparation of material for identification and sustainable use of native trees of the Serra dos Tapes.
