RELAÇÕES ENTRE A FLORÍSTICA ARBÓREA E CARACTERÍSTICAS DO SOLO EM UM FRAGMENTO DE FLORESTA ATLÂNTICA, TAMANDARÉ – PE

This study aimed to relate the tree components flora with the physical and chemical characteristics of soil over a topographic gradient, in a patch of dense rain forest in the Saltinho Biological Reserve, Pernambuco State. The floristic survey was carried out in 42 plots distributed in a gradient of three topographic positions, for those individual living trees with DBH ≥ 15 cm. The vegetation floristic similarity was analyzed by using the Euclidean distance and the soil by means of physical and chemical variables. The relationship between the chemical variables of soil and vegetation was done by canonical correlation. The slope and the top were the positions with higher floristic similarity. Species occurred with preferential development in the flatland, because of the soil fertility and on the top, due to the organic carbon grade and in the both positions, because of the moisture.
