Resumé en portugais
O estudo objetivou verificar as interferências de espécies vegetais utilizadas nos trabalhos de recomposição da cobertura vegetal da Serra do Mar, Cubatão - SP, no processo de regeneração natural. Foram selecionadas oito áreas deslizadas, sendo quatro plantadas com Brachiaria brizantha, espécie exótica, e quatro com espécies nativas herbáceas presentes nas suas proximidades. Coletaram-se oito amostras na área deslizada e oito em seu entorno, plantadas há quatro anos e seis meses. Os resultados mostraram que todas as espécies plantadas interferiram no processo de regeneração natural, sendo a B. brizantha a que mais coibiu e Calathea sp. a que menos restringiu. Entre as espécies nativas herbáceas plantadas a que maior limitação impôs ao processo de regeneração natural foi a Heliconia velloziana L. Emidg. As outras espécies; Philodendron imbe Schott, Pleurostachys sellowii Kunth e Mikania lanuginosa D.C. tiveram interferência intermediária sobre o processo de regeneração natural.
Titre en anglais
Natural regeneration and plantation of Brachiaria brizantha (Hochst. ex A. Rich.) Stapf and native herbaceous species in the landslide areas of the sea mountain in Cubatão - SP, Brazil
Resumé en anglais
A study was carried out to verify how the seeded species would interfere in the recomposition of the native vegetation on the Sea Mountain, in Cubatão, State of São Paulo. Eight areas were selected for studying. Four landslide areas were planted with a exotic species (Brachiaria brizantha) and another four with native herbaceous species. Eight samples were taken in the planted area and another eight were taken in its neighborhood, four years and half after the planting of the eight species. The results showed that all planted species interfered in the natural regeneration process. B. brizantha was the most interfering species, while Calathea sp. was lhe least one. Among the planted native species, Heliconia velloziana L. Emidg. was the most limiting to the natural regeneration process. The other three herbaceous species, Philodendron imbe Schott, Pleurostachys sellowii Kunth and Mikania lanuginose D.C. had only an intermediate effect on the natural regeneration process.
