However, given the lack of understanding of how human intervention, such as the removal of regenerating individuals from the forest, infl uences the composition and structure of the plant community, there is a pressing need for further research. Our primary objective here was to identify the eff ects of seedling removal on natural regeneration in forest communities and to characterize seedling bank dynamics three years after anthropogenic intervention. A randomized block design was used for the experiment, consisting of fi ve removal intensities (0, 25, 50, 75, and 100% removal), with evaluations conducted every three months for three years. All individuals of the shrub-arboreal component between 5–55 cm heights were measured. Collected data were analyzed to determine the impacts of the removal of individuals and the infl uence of environmental elements on the seedling community. We found that the shrub-arboreal component of the forest community exhibited marked resilience three years following the removal of regenerating individuals. Removal of up to 50% of regenerating individuals does not appear to interfere with plant community dynamics, suggesting species with a high density of individuals in the seedling bank are resilient to the impacts of human intervention. Although climatic seasonality also aff ects seedling bank dynamics in plant communities, this eff ect depends on the level of human intervention in an area and, therefore, has been omitted from the analysis.

No entanto, intervenções como a retirada de indivíduos regenerantes da floresta podem influenciar a composição e a estrutura da comunidade de plantas, devendo ter seus impactos previamente estudados. Dessa forma, o presente estudo objetivou identificar os impactos da remoção de plântulas sob a regeneração natural de uma comunidade florestal, bem como caracterizar a dinâmica do banco de plântulas três anos após intervenção antrópica. O experimento foi conduzido no delineamento blocos ao acaso, sendo os tratamentos compostos por cinco intensidades de remoção de indivíduos do banco de plântulas (0, 25, 50, 75 e 100% de remoção) e realizadas avaliações a cada 3 meses, por um período de 3 anos. Foram mensurados todos os indivíduos do componente arbustivoarbóreo com altura entre 5 e 55 cm. Os dados obtidos foram analisados quanto ao impacto causado pela remoção dos indivíduos e a influência dos elementos ambientais sobre a comunidade de plântulas. Após três anos de observações constatou-se que a vegetação do componente arbóreo-arbustivo apresentou capacidade de resiliência posterior a remoção dos indivíduos regenerantes. De maneira geral, a remoção de até 50% dos indivíduos não interfere na dinâmica da comunidade vegetal, podendo assim ser utilizada para espécies que apresentam elevada densidade de indivíduos no banco de plântulas. A sazonalidade climática direciona a dinâmica do banco de plântulas em comunidades vegetais, no entanto esta influência é dependente do nível de intervenção antrópica a qual a área foi submetida.
