Caracterização da estrutura de produção de madeira dos micro e pequenos produtores da região do estuário amazônico:

Abstract

ABSTRACT 1: Published information and limber production data of micro and small producers were collected in the municipalities of the Amazon estuarinc region. Macapd and neighbourhood aiming at supporting decision making by Ibama's Pard Technical Advisory Committee to establish maximum annual production per year by each producer. Based on this study, a maximum volume of 200 m3 per ha per year was set up. This allowable production is to be regulated by special act to be edited both by Ibama's offices in Pard and Amapd States. ABSTRACT 2: This article presents a conversion factor of geometric volume of standing trees to Francon volume aiming to standardise the volumes reported on the Authorisation for Transpoit of Forest Products issued by Ibama. Therefore the expression Vf = 0.7854 x 0.7 x standing tree volume should he applied by the producers to calculate the volumes to be recorded on the authorisation form sheet. ABSTRACT 3: Ibis paper deals with the definition of a methodology for calculating sawn Nolumc from round volume based on both geometric and Francon measurements. The coefficients for converting geometric and Francon volumes were respectively, 58.2% and 74%. These coefficients which correspond respectively to 1.7 and 1.4 should be adopted by IBAMA (PA).
