Resumo: Veredas (palm swamps) is a type of vegetation associated with watercourses, characterized by the presence of Mauritia flexuosa palm trees. These systems are not well understood and suffer from high anthropogenic pressure. The aims of this study were to describe the natural regeneration of two swamp forests in vereda systems with different anthropogenic impacts and investigate if the variation in these plant communities are associated to edaphic conditions. The study was performed in preserved and impacted sites located in the Environmental Protection Area of the Pandeiros River in northern Minas Gerais. At each site, one hundred 25 m2 plots were established for surveying regenerating shrubs and trees (≥1 cm diameter at the base of the stem and < 3 cm diameter at breast height). Vegetation structure was evaluated by phytosociological parameters, similarity index, and size distribution of individuals. Regenerating strata was correlated with chemical and physical soil analyses. The vegetation at the preserved site was characterized by a higher number of individuals and a lower diversity but contained species that were typical of flooded areas. The results also showed differences in soil nutrient availability between sites that influenced the distribution of species at the two study sites.

Estes sistemas não são bem compreendidos e sofrem grande pressão antrópica. Os objetivos deste estudo foram descrever a regeneração natural de duas florestas higrófilas em sistemas de veredas com diferentes impactos antropogênicos e investigar se a variação nesta comunidade de plantas está associada as condições edáficas. O estudo foi realizado em sítios preservado e impactado localizado na área de Proteção Ambiental do rio Pandeiros, norte de Minas Gerais. Em cada sítio, 100 parcelas de 25 m2 foram estabelecidas para o levantamento dos arbustos e árvores regenerantes (≥1 cm de diâmetro na base do caule e < 3 cm de diâmetro na altura do peito). A estrutura da vegetação foi avaliada pelos parâmetros fitossociológicos, índice de similaridade e distribuição de tamanhos dos indivíduos. O estrato regenerativo correlacionou com as análises químicas e físicas do solo. A vegetação no sítio preservado foi caracterizada por um maior número de indivíduos e menor diversidade, mas continha espécies típicas de ambientes alagados. Os resultados também mostraram diferenças na disponibilidade de nutrientes do solo entre os sítios que influenciaram a distribuição de espécies nas duas áreas estudadas.Universidade Federal de Lavras (UFLA)2016-04-292017-08-01T20:14:16Z2017-08-01T20:14:16Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfÁVILA, M.
