Natural regeneration under reforestation of Araucaria angustifolia and Pinus sp. in Tunas do Paraná, PR, Brazil

This study aimed to assess the natural regeneration in stands of Araucaria angustifolia (PA) and Pinus sp. (PP) without management in Campinhos State Park, in the Municipality of Tunas do Paraná, Parana State, Brazil. Eighteen plots of 10 m2 were installed, 7 plots for PA and 11 for PP. All trees hi...

Abstract: This study aimed to assess the natural regeneration in stands of Araucaria angustifolia (PA) and Pinus sp. (PP) without management in Campinhos State Park, in the Municipality of Tunas do Paraná, Parana State, Brazil. Eighteen plots of 10 m2 were installed, 7 plots for PA and 11 for PP. All trees higher than 1.5 m were sampled and their circumference were measured at 1.30 m above ground level. In PA stand there were 586 individuals, corresponding to 67 species and 29 families and in PP stand 442 individuals of 58 species and 22 families were measured. The most important species in PA were Cordyline spectabilis, Lonchocarpus muehlbergianus and Clethra scabra; and in PP were C. spectabilis, Lonchocarpus sp.1 and Cupania vernalis. PA showed phytosociological parameters and diversity higher than PP. The floristic composition was similar for both stands, which denoted the regenerative potential of PP.
Translated abstract: Com o propósito de estudar a regeneração natural em povoamentos de Araucaria angustifolia (PA) e Pinus sp.(PP), sem manejo, nas áreas do Parque Estadual de Campinhos, no Município de Tunas do Paraná, PR, foram instaladas 18 parcelas de 10 m2, 7 para PA e 11 para PP. Amostraram-se todos os indivíduos maiores que 1,5 m de altura, dos quais se mensurou o perímetro à 1,30 m do nível do solo. No PA obteve-se 586 indivíduos, 67 espécies e 29 famílias e no PP foram mensurados 442 indivíduos de 58 espécies e 22 famílias. As espécies mais importantes no PA foram Cordyline spectabilis, Lonchocarpus muehlbergianus e Clethra scabra, e no PP C. spectabilis, Lonchocarpus sp1. e Cupania vernalis. O PA apresentou parâmetros fitossociológicos e diversidade superiores ao PP. A composição florística foi similar em ambos, o que denotou o potencial regenerativo do PP.
