This study was carried out to estimate a volume equation from a logarithmic model of Schumacher & Hall (1933) for comercial volume determination and a taper equation from the model of Demaerschalk (1972), to estimate wood multiproducts yield in Floresta Atlântica. Data were collected in Gleba C (C Glebe), with 289.5 hectares, owned by Floresta Nacional do Rio Preto (Rio Preto National Forest), under the administration of IBAMA, located in Conceição da Barra - Espírito Santo, Brazil. A total of 165 standing trees were measured, subdivided into 10 diameter classes, with bole quality QF1, with the greatest VI, and/or species of commercial value. These trees represented 62 species and 38 families. The volume equation fitted well within the data, with <img border=0 id="_x0000_i1029" src="../../../img/revistas/rarv/v27n6/a06img01.gif" align=absmiddle>2 of 0.9815, and normally distributed residues. The taper equation also fitted well within the data, with <img border=0 id="_x0000_i1030" src="../../../img/revistas/rarv/v27n6/a06img01.gif" align=absmiddle>2 of 0.9346 and graphic distribution of the residues was normal. The F test (Graybill, 1976) showed equivalence between the observed and estimated diameters by the taper equation. The taper equation algebric transformations allowed to estimate the height for a given superior diameter d, and the trunk volume for a desired use, allowing to evaluate the amount of multiproducts for standing trees.
