Utilização de plantas nativas na restauração ecológica de um ecossistema de restinga

Abstract

The use of exotic plants in degraded areas is a reality worldwide. The second major cause of biodiversity loss is related to exotic species. With that said, encouraging the use of native plants in restoration of green areas can be a great ally for the environmental ENRICHMENT of native vegetation, maintenance and preservation of the ecosystem, improvement of the climate and aesthetics, and quality of life for the inhabitants of that area. Given this context, this study focus on proposing the use of native plants of the Parque das Dunas as a way of restoring degraded areas. For that, it was necessary to make a direct transplant of seedlings WITHIN the park to compose the high diversity islands. Twenty-two islands were arranged in total, in an area of 50 m², using 170 individuals composed of Anthurium affine Schott, Hohenbergia littoralis L.B.Sm., Epidendrum denticulatum Barb. Rodr., Cyrtopodium Paranaense Schltr., Syagrus schizophylla. (Mart.) Glassman. and Guapira pernanbucensis (Wed.) Lundell. Results showed that after six months from the start of the restoration process, 23.82% of the individuals emitted gems, and 90.59% of the species survived. The high survival rates obtained in the present study may be associated to the direct transplant technique, demonstrating that the rescue and management of the Restinga plant species can be favorable in face of the applied methodologies.
