| Summary: | This study was done in a 6 ha fragment of Mixed Ombrophilous Forest in the county of Tijucas do
Sul, - Paraná. Its aim was the elaboration of a sub-canopy species catalog and evaluation of the perturbation
of anthropic impacts on the composition of this forest stratum. Collection of botanical material was conducted
monthly from October 2001 until September 2002. Two sample units of 100 x 100 m. Were usid and 89
species, 54 genera distributed into 32 botanical families were identified, belonging to 84 species in area A
(shrub) and 27 species in area B (forest). In the shrub area the most representative families were Solanaceae,
with 16 species, Asteraceae (15) and Melastomataceae (14). In the forest area the most frequent families were
Melastomataceae with 6 species, Solanaceae (5) and Myrtaceae (5). The predominance of species from
Solanaceae and Asteraceae in the shrub area demonstrates the pioneer character of these families, playing an
important role in the re-establishment of this forest. Species of the Solanaceae family in the forest were most
abundant along the footpaths inside the forest. The data showed that for this fragment, regeneration is
successfully taking place and the continuation of this process includes restricted access to the area. |
