<b>Geoprocessing applied to the phytosociological survey in permanent plots</b>

Abstract

The goal with this work was to create a georeferenced data bank to follow the phytosociological changes of types of trees along the time and its geographic distribution in the field of study. To the phytosociological survey permanent parcels were plotted in the field of study along the floodplain of the rivers Carro Quebrado and Cascavel, both located in the Campus of the Universidade Estadual do Centro Oeste (UNICENTRO – CEDETEG), in Guarapuava city, Parana state. In each part the attributes analyzed were: sociologic position (SP); class of crown (CC); characteristics of trees (CT); quality conditions of the trunk (QCT); conditions (Cs). These parts were put into spaces with use of the Global Positioning System (GPS) and the data were sent to the SPRING software with the intention to build a cadastral data bank to follow and analyze the development of the local vegetation. The creation of this data bank allowed following the development of trees in a time scale, showing the evolution of the part of the forest studied.
