Toposequence segmentation and phytosocial characterization of a copse from a Mixed Ombrophilous Forest

Abstract

This work aim to characterize flora composition and structure of a copse, in Quatro Barras County, located in steppe area in first highland of Paraná, considering soil and topographic relief conditions. Based on the definition of compartments in the environment, that considered the forms and declivities of the slopes and the characteristics of soil, parcels for trees sampling had been installed. The species had answered in diversity and density to the different conditions of drainage of Cambissolos and Gleissolos of the copse. Podocarpus lambertii demonstrated high adaptability to soil with different moistures regimes, while Myrcia laruotteana presented narrow relation with water saturated soil. The environmental segmentation based on geomorphology and soil types showed to be fundamental aspect to better understand plants species distribution on the landscape.
