Phytosociological parameters of a fragment of mixed ombrophilous forest in regeneration after burning in the municipality of Segredo

The natural regeneration after natural or anthropogenic disturbances is an important element to reestablishing shrubby-arboreal species, that is, in the restoration of abundance. To the analysis of the floristic composition and some phytosociology parameters of one three years old clearing that was burned in a mixed ambrofila forest near Segredo, RS, was sampled 16 parts measuring 2m x 2m, totaling 64 m². Was found 240 individuals belonging to 42 shrubby-arboreal species. Therefore naturally trough processes of regeneration, the environment is covering himself, showing notable abundance. The species diversification may be contributing to the formation of different ecological guilds, which will facilitate in a time range, the gradual restoration of the degraded area that can be managed to achieve higher success.The present work aims to describe the structure and floristic composition of the natural regeneration in a clearing of a Fragment of Mixed Ombrophilous Forest that underwent an intervention by burning after three years in the Municipality of Segredo, Rio Grande do Sul State, Brazil. We sampled 16 plots of 2 x 2 m, totaling 64 m2. It was established that all plants with height greater than 0.3 m were included as criterion in the floristic survey. We found 240 plants belonging to 42 arboreal-shrub species
