Fitossociologia e floresta estacional decidual. The Parana River basin – an area of 5, ha located in Brazil- has a highly diverse phytophysiognomy and scarce flora information.

What do we win ‘confounding’ species richness and evenness in a diversity index?

Wood extraction and pasture activities have decisively contributed to the removal of vegetation in this area. Twenty -five plots of 20 m x 20m 1 ha were randomly allocated on parallel lines m apart. Trees with stem diameter at 1. In the phytosociological study, individuals comprising 48 species, 38 genera and 24 families were sampled.


The species with the highest importance value IV were Myracrodruon urundeuva Diversity was close to that found in other seasonal deciduous forest studies in the region. Phytosociology and seasonal deciduous forest. Gerhardt, ; Werneck et al.
