“…The diversity of species in restoration plantations is widely discussed among researchers (Aronson et al, 2010;Salomão et al, 2013;Brancalion et al, 2015;Amazonas et al, 2018). According to Martins (2014), the use of few species in restoration projects, in a scenario with low resilience, can lead to the failure of the process, since pest attacks or repeated degrading actions can eliminate several tree individuals.…”

The evaluation of the forest restoration scenario is of great importance, with floristic composition and diversity being among the most used ecological variables as indicators. This research aimed to identify the current situation, in terms of species composition and diversity, of two riparian forests under restoration based on a reference ecosystem, the Brazilian Atlantic Forest. Twenty permanent plots (250 m²) were located in areas under restoration process (AR1 and AR2) and in a forest fragment of the region which served as a reference ecosystem (ER). We sampled, identified and classified all tree individuals with CBH ≥ 15.0 cm in each plot. Aiming to understand species richness and diversity, besides the traditional indexes (Shannon and Simpson), we also estimated the effective numbers of Hill’s diversity (qD = 0, 1 and 2) considering rarefaction (P ≤ 0.05); and to detect floristic similarities among the study areas we performed a Principal Coordinate Analysis (PCoA). We found dissimilarity among ARs and ER, and the presence of exotic species, indicating that, as recommended, such reference should have been taken into account during the planning of the restoration action. Considering the effective numbers of species (qD) we found differences between the areas, species richness and diversity was higher in ER > AR2 > AR1. We also show that among the restoration areas, with the same age and submitted to the same conditions, AR2 has features that allow us to conclude that this area has a bigger chance of success in the restoration process. However, aiming environmental sustainability, we suggest that some corrective actions should be taken in order to favour the reestablishment of ecological processes in these areas.

“…According to Salomão et al (2013), the selection of species for planting implementation is important for the community structure (abundance, spatial distribution, biomass, scale or cover) since this selection impacts the occurrence of the other species and consequently, the successful recovery of areas that were degraded by open-air mining.…”

Forest Restoration Evaluation Through Indicators in Areas of Bauxite Mining

The state of Pará ranks second in Brazilian mineral production, where bauxite accounts for 84% of total mineral extraction, with negative impacts on the environment as a result. The determination of objectives and targets using environmental indicators as a tool to evaluate forest restoration processes is essential in the recovery of these exploited areas. This study aimed at evaluating the efficiency of forest restoration techniques by means of 13 qualitative and quantitative indicators for monitoring post-bauxite mining operations. Permanent plots were implanted in revegetated areas with the use of two techniques: planting of seedlings and stewarding of natural regeneration. It is concluded that the techniques are efficient for the recovery of forested area. However, natural regeneration showed greater efficiency for restoration for Density, Erosion and Exotic Species indicators. Still, natural regeneration should not be the sole option in the processes of ecosystem restoration, since planting proved to be more efficient for some indicators.

“…A identificação de espécies-chave, que são aquelas que controlam a estrutura da comunidade devido à sua abundância, distribuição espacial, biomassa, porte ou cobertura e que influenciam a ocorrência das demais espécies associadas, é de fundamental importância para o sucesso da restauração florestal em áreas degradadas, principalmente por mineração a céu aberto (Salomão et al, 2013).Assim como, compreender a dinâmica dos processos da floresta e visualizando as mudanças, detectando as causas e determinando qualitativamente e quantitativamente o conjunto, constitui um grande desafio nos trabalhos de manejo de precisão para estabelecer relações e previsão de consequências que sejam ambientalmente corretas, economicamente viáveis e socialmente aceitas e justas (Nappo, 2002).…”

As operações de lavra de seixo no município de Ourém tem início com o desmatamento, descampamento, escavação, carregamento, transporte e restauração das áreas mineradas. O objetivo deste trabalho é recomendar o uso de espécies florestais nativas pré-selecionadas com características ecológicas para favorecer a rápida recuperação de uma área ambiental degradada pela retirada de seixo. O procedimento de coleta de dados foi planejado em função dos objetivos geral e específicos da pesquisa, sendo realizadas coletas de dados em fontes secundárias e fontes primárias. Foi utilizada a estrada como trajeto para percorrer uma extensão de 3 km para realizar o diagnóstico florestal. A identificação florestal foi realizada através da observação dos indivíduos adultos nos dois lados da estrada. A lista de espécies adquirida na área da mineradora, podem ajudar na recuperação de áreas alteradas pelas atividades de mineração de seixo no município de Ourém – PA e de outras áreas com características semelhantes. A presença numerosa de famílias com tolerância a sol e de espécies pioneiras demonstra a diversidade florística desse ambiente e a qualidade do sítio. Foram registradas espécies típicas das florestas tropicais amazônicas como Bertholletia excelsa Humb. & Bonpl, Aniba rosaeodora Ducke e Vouacapoua americana Aubl., demostrando que precisamos revegetar os ecossistemas degradados.
