This work investigated how richness, abundance, composition and structure of woody and herbaceous vegetation were altered by the proximity of an edge between Araucaria forest and pasture in South Brazil. Herbaceous and woody species including seedlings were surveyed in 42 plots of 5 × 5 m randomly placed at the following distances: 5 and 50 m from the edge into the pasture and 0, 25, 50, 100 and 250 m from the edge into the forest. There was a significant increase in vegetation cover, richness and abundance of woody species, woody seedlings and herbaceous plants at the edge (0 m). These variables, in general, decreased from 25 to 50 m from the edge into the forest in comparison to the forest interior. Few seedlings of woody plants were able to establish themselves in the pasture. There were continuous changes in species composition that occurred in the studied gradient due to the invasion of light-demanding species and the disappearance of some shade-tolerant species at the edge. In conclusion, the forest edge studied generated changes in the plant community that extended up to 50 m into the forest. Neste estudo investigamos como riqueza, abundância, composição e estrutura da vegetação lenhosa e herbácea foram alteradas pela proximidade de uma borda entre floresta com araucária e pastagem no sul do Brasil. Espécies lenhosas e herbáceas, incluindo plântulas, foram analisadas em 42 parcelas de 5 × 5 m dispostas aleatoriamente nas seguintes distâncias: 5 e 50 m da borda para dentro do campo e 0, 25, 50, 100 e 250 m da borda para dentro da floresta. Houve um aumento significativo na cobertura da vegetação, riqueza e abundância de espécies lenhosas, plântulas lenhosas e plantas herbáceas na borda (0 m). Essas variáveis, em geral, decresceram nas distâncias 25 a 50 m da borda para dentro da floresta em relação ao interior da mesma. Poucas plântulas lenhosas foram capazes de estabelecer-se no campo. Houve uma mudança contínua na composição de espécies que ocorreu no gradiente de borda devido à invasão de espécies heliófilas e o desaparecimento de alguma espécies tolerantes à sombra na borda. Concluímos que a comunidade de plantas encontra-se alterada na borda florestal estudada em uma extensão que vai até 50 m para dentro da floresta
