Resumen:
Summary: In order to determine environmental impact indicators based on vegetation characteristics, that would generate the forestry monoculture with the adjacent native forest, 32 sample unit were installed in an area of LIPSIA private enterprise, Esperanza Departament, Misiones, with those characteristics. The plots of 100m2 were distributed sistematically every 25meters. The vegetation was divided in stratum: supperior, middle and inferior. There were installed 10 plots in native forests. 10 plots in Pinus elliotti forests, 6 plots in Araucaria borders forest and 6 plots in his plantations. In the studied areas werw identified 15o species of plants. In the inferior stratum there were found differences as function of various floristic diversity indexes. In all the cases the native forest shower larger diversity than plantations,followed by Pinus and Araucaria forests. All the studied forest fitted to a logarithmical series of species distributions, that would indicate the incidence of a environmental factor in this distribution.
