Desenvolvimento de espécies plantadas em bordas de veredas visando a restauração ambiental

Abstract

The ecological restoration tends to re-establish the biodiversity and the ecosystems services of the natural environment. Planting seedlings is the most insulated technique when there’s no forest remains at the neighboring areas. This paper aims to evaluate the development of species implanted at the palm swamps edges. 3055 individuals belonging to thirteen families, distributed in 42 species were planted. To evaluate the development of the species, all the individuals had their height and DAS measured. Richness, abundance, height, diameter, dominance and survival were calculated and the species were classified by guilds (pioneer, secondary or climax), as well as soil analyses. The survival rate was 51%. There was an increase on the height, diameter and dominance and a reduction on the abundance and richness in 2021. Secondary species had the higher rate of survival, 52%, followed by pioneers, 37%, and climax, 11%. At the second evaluation, secondary species remained with a higher number of individuals. Soil analysis has shown that the nutrients vary by plots, as well as the composition. The restoration process presented positively, with a survival rate within the standards previously evaluated in other studies, as well as the development of surviving seedlings.
