Comparação entre áreas em restauração e área de referência no Rio Grande do Sul, Brasil

Abstract: RESUMO -Este estudo teve por objetivo avaliar a evolução da restauração de duas áreas degradadas em unidade de conservação de proteção integral, no bioma Mata Atlântica, no Sul do Brasil. Foram avaliados atributos da composição florística e da estrutura da vegetação, assim como a atividade enzimática do solo (amidase, urease, fosfatase e arilsulfatase), envolvida em processos ecológicos, capazes de caracterizar diferentes áreas em restauração. A vegetação do estrato superior foi amostrada em 18 parcelas de 10 … Show more

“…Marcuzzo et al (2014) [11] observaram que duas áreas perturbadas no Rio Grande do Sul, que foram restauradas a 7 anos, apresentavam maior regeneração natural com síndrome de dispersão anemocórica e na área preservada apresentavam maior regeneração natural com dispersão zoocórica. Observa-se que as sete espécies (58,3%) predominantes da regeneração natural do fragmento estudado apresentam dispersão anemocórica (Tabela 1).…”

“…The Conservation Unit was created due to the construction of Dona Francisca Hydroelectric Power Plant (HPP) on the River Jacuí in 2005. According to Marcuzzo et al (2014), there was a set of residences for workers of the power plant in the recovery area, the target of this study. With the conclusion of the HPP, these residences were demolished, and the area submitted to restoration.…”

“…The restoration process began in 2003 with the plantation of 25 seedlings of native species, in spacings of 4.0 m × 4.0 m. The plantation was conducted after opening the planting pits, with no other cultural treatment, according to the requisites established by the environmental organ for the restoration of the area. During the plantation, the soil presented fragmented rocks and the rubble from the demolitions (Marcuzzo et al, 2014). Ten years after planting, when the field was measured, there was natural regeneration in various densities under the canopy of the planted trees, as well as grasses and invasive tree species.…”

“…In addition, the monitoring of such regenerating areas can provide relevant information regarding the species being initially established, and may serve as a basis for the selection of potential species to be used in restoration projects in different environments ; Daronco et al, 2013;Marcuzzo et al, 2014), since the collection of matrix seeds in the surroundings of the area where the restoration will be carried out can increase the probability of reforestation success, in terms of survival and growing (Sebben, 2006), as well as guarantee the local genetic of plants and allow greater ecological adaptation plasticity to the local conditions (Palma and Laurence, 2015).…”
