|metadata.revistascielo.dc.description:||Leaf Area Index (LAI) and Vegetation Area Index (VAI) estimations have been performed in 36 sample points located in Eucalyptus sp. canopies situated in Aracruz and São Mateus (ES) towns and from FIBRIA S/A company. Three different techniques have been applied: destructive method, hemispherical photos taken inside the canopies and LAI-2000 (LICOR). The field data collections were carried out in two seasons in order to detect phenological changes that should affect both LAI and VAI values. LAI values estimated by destructive method were higher than VAI values estimated by the indirect methods in absolute terms. During the rainy season the relationships between LAI and VAI, for the two indirect methods, were stronger and more consistent than those verified for the dry season. The relationships between VAI (indirect methods) were consistent than those calculated between LAI and VAI.|
