Uso da análise multivariada para estabelecer relações ecológicas em uma área de restauração florestal

Abstract

The study was conducted in a forest restoration area in the Cerrado biome. The aim of this study is to determine ecological standards in an area of forest restoration, through multivariate analysis methodology using principal component analysis. They were allocated 10 plots of 288 m² distributed randomly in the area, making photon flux density studies, canopy cover, ground cover and forest inventory in two seasons (dry and wet). Several links were found between, important variables for the success of forest restoration, negative correlation of grass with natural regeneration in the rainy season, a negative correlation of litter and grasses in the dry season. Efficient use of multivariate analysis, responding to data variance greater than 60%, if used as a tool for annual use, reference may best ecological standards of the area, can be used to identify forest restoration indicators
