Resumo: | This study aims to detect the composition, abundance patterns, and successional stage distributions exhibited by arboreal species inside and at the linear edge of a submontane seasonal forest in the Chapada Diamantina (12°28'31'S, 41°23'14'W), Bahia, Brazil. The individual plants with breast height diameters ≥5 cm were sampled in 30 quadrats (10 m × 10 m), 15 in the forest edge and 15 inside the forest. Species were classified according to successional category. Phytosociological and diversity indices were calculated. Shannon indices were compared using Hutcheson's t-test, and the remaining parameters were analyzed by ANOVA. Linear edges exerted a high impact on the floristic composition, diversity, and abundance of species, though little interference was observed in the structure of the community, since phytosociological parameters and the proportions of successional categories did not differ between the edge and inner forest fragment. The impact of linear infrastructure was similar to that of other border types. Additionally, even though the distance between forest fragments was very short, an edge effect was observed, which underlines the importance of linear forest edges to biodiversity conservation.
