Valorização do conhecimento popular na identificação de espécies não madeiráveis promissoras para o manejo de florestas secundárias por agricultores familiares na microrregião Guajarina

Abstract

The municipality of Capitão Poço, in northeastern Pará, started its colonization in the mid 1950's; today, a large part of its primary vegetation has already been transformed into areas of secondary succession vegetation (capoeira), plantations and pastures. Studies show that if properly managed, these stands can be extremely productive, because a number of products of economic value can be found there. With the intention of providing subsidies for the management of these areas, the present study proposed, through participatory research, to contribute to the identification of non-timber forest plant species with potential uses in the areas of grasslands in northeastern Pará (PA-Brazil), in an attempt to provide alternatives for improving environmental conditions and the quality of life of the local population. Structured interviews were carried out with family farmers from the community of Carrapatinho, located in the municipality of Capitão Poço-PA, where information was collected on the use of the most important non-timber plant species for the community, as well as botanical samples of these species. The botanical material collected was identified, and the information about each species was computed in a model identification form. A total of 49 species were found, distributed among 28 families and 45 genera. The families with the largest number of species were LEGUMINOSAE (10) and APOCYNACEAE (4). The predominant habits are: arboreal, with 77.55% and climbing, with 10.20%. The most found uses were handicraft, with 28.78% and medicinal, with 25.75%. The most used plant organs were fruit with 37.14% and bark with 12.85% of the total. The results presented show that the species of secondary vegetation, if framed by management typology according to their use, indicated by the local population, can be put to much better use, thus increasing the income of family farmers and environmental conservation.
