CERRADO FORESTS: SEASONAL FOREST AND CERRADÃO

The Cerrado biome presents different physiognomies distributed throughout severalBrazilian states. Studies related to species distribution as direct environmental factorsmay subsidize forest restoration projects. The objective of this study wasto evaluateecological and structural differences and determine the species distribution based onsoil factors in two physiognomies types of Cerrado. Data sampling was conducted inthe area of influence of the sugar cane industry in southwest of Goias, Brazil. Soilsamples were collected in those plots and analyzed chemically and psysically. Theresults of the soil characteristics were useful to verify if the species distributioncorrelate with soil patterns through canonical components analysis (CCA).Thestructural aspects were higher in the plots identified as seasonal forest. Although theEcological aspects, such as species diversity, were higher in the cerradao. The CCAshowed a positive correlation between the tree species distribution withphysicochemical characteristics of soil. The analysis showed a positive correlationbetween the distribution of tree species and the physicochemical characteristics ofthe soil. A group of species was related to higher fertility in the soil and clay content.Another group was correlated with low fertility and higher sand content soils.
