Woody species richness and abundance in a reforestation of Pinus taeda L. and an Araucaria Forest in the Center - East Region of Paraná State, Brazil

Abstract

This study was conducted in two sites (secondary forest and reforestation of Pinus taeda) in the Ecological Park of Klabin S. A (Telêmaco Borba, Paraná, Brazil). Six plots were distributed at each site with the aim of record species richness and abundance and search for correlations with to canopy cover, distance from the forest edge and thickness of litter layer, as well as to the dispersal syndrome and propagule size. We sampled 134 individuals belonging to 39 species. Litter did not affect richness and abundance of species at both sites, but richness was positively correlated with canopy cover and distance from the edge. The prevalent dispersion syndrome in both areas was zoochory and diaspores size did not differ between studied sites.
