| Popis: | The floristic forest inventory of Santa Catarina State in Southern Brazil aims at quantifying the forest resources and increasing the knowledge on vascular plant diversity. The study includes sampling of trees, shrubs, herbs and vascular epiphytes. Santa Catarina State¿s surface is about 95,443 km², covered by four major vegetation types: Dense Tropical Humid Forests, Mixed Rainy Forests with Araucaria angustifolia, highland grasslands and Seasonal Deciduous Forests. Forest land cover is about 30%, although extremely fragmentized, especially in the western region. This pilot study has been conducted in Mixed Rainy Forest domain during 2005, measuring 74 sample plots (2000 m² each) randomly distributed in this forest type's area (41,380 km²). Besides the usual analysis of vertical and horizontal vegetation structure, species density data were utilized to construct species/samples matrix that was the basis for Detrended Correspondence Analysis (DCA). The survey results indicate that Myrtaceae, Fabaceae, Lauraceae are the most numerous families, followed by Asteraceae and Solanaceae. The survey registered 133 species with DBH ¿ 10cm, 101 species with DBH |
