ÍNDICES DE SÍTIOS PARA Hovenia dulcis Thunberg NA REGIÃO CENTRAL DO ESTADO DO RIO GRANDE DO SUL, BRASIL

The main objective of this work is to study the index forest sites build, for the dominant height, of populations located in the central area of the state of Rio Grande do Sul. To do that, information from 3 stands located at FEPAGRO was used. To construct the curves index sites forest, information from 18 dominant trees was collected in the 4 sites, observing the methodology for the analysis of the bole.
