Processo de restauração em um fragmento de restinga, aldeia Tramataia, Marcação - PB

Abstract

Restinga is defined as vegetation established on sandy soils that occurs in the coastal plain region. The study was conducted on Ilha das Moças, Aldeia Tramataia, municipality of Marcação on the northern coast of Paraíba. The village is part of the Rio Mamanguape Environmental Protection Area (APA) and has a history of logging, which has resulted in a significant loss of tree vegetation. As an attempt to restore the ecosystem, the Cacique Iniguaçu Indigenous State School annually plants seedlings during Environment Week; however, although this action has been recurring for about 10 years, the results are still limited. In this sense, this study aimed to evaluate the development of seedlings planted in a restinga area undergoing a restoration process and the influence of nucleation on their growth and survival. During the years 2023 to 2025, a survey of 12 nucleations was carried out, with 44 seedlings of six different species. The nucleations were monitored annually for their circumference, and the seedlings for their height and circumference annually, and their survival was monitored monthly. Nucleated seedlings showed a growth rate of 31.5%, while the seedlings showed an average growth rate of 5.67%; 14 individuals did not survive. We conclude that nucleation techniques favor success in the restoration process in restinga areas.
