Identificação de potenciais usos não-­madeireiros em remanescentes de floresta ombrófila mista, Bituruna - Paraná

Abstract

The present study aimed to characterize the potential of non­timber uses of species, located in forest remnants in the municipality of Bituruna, PR, where Municipal Natural Parks will be created. For data collection, plots were installed with a 25m sample line and 2m transects, totaling 16 plots in the first park, 24 plots in the second and 22 plots in the third park. The survey was carried out only by tree and shrub species, witha height equal to or greater than 50 cm, measuring from the base of the soil to the life part of the plant. The floristic survey of the area was also carried out using the walking method. In both methods, the collection of botanical material was carried out. The collected species were tagged and then identified in herbariums. After being classified and categorized, according to the bibliography consulted. The defined categories were: food, artisanal, ecological, fiber, fodder, medicinal, biochemical products, essential oils, ornamental and other uses. The study identified the occurrence of 141 species belonging to 39 botanical families, and 102 species were identified with potential for non­timber forest use. The families that had the highest occurrence were: Myrtaceae (17), Asteraceae (11) and Lauraceae (7). The categories with the highest percentage of species were medicinal (24%), ornamental (23%), ecological (22%), essential oils (11%), food (10%), biochemical products (7%), and the other categories presented values less than or equal to 1%. The yerba mate (Ilex paraguariensis) native in Mixed Ombrophilous Forest, has real potential for non­timber use, presents commercialization mainly in the food area. Being, in the studied region, the most commercialized non­timber forest product. It is concluded that there are many species with potential for non­timber use that are not commercialized. Thus, the study contributes with information on NTFPs, as a way of increasing income for small family farmers in the region, and their extraction activity around the boundaries of the parks.
