Abstract

SANTOS, Joaquim dos  and  JARDIM, Fernando Cristovám da Silva. O potencial madeireiro da terra firme em relação à demanda das serrarias do Amazonas. Acta Amaz. [online]. 1988, vol.18, n.1-2, pp.83-92. ISSN 1809-4392.  https://doi.org/10.1590/1809-43921988182092.

Data from five "terra.firme" (upland) forest inventories executed within a 200 km radius of Manaus were analyzed in order to evalvate wood potential in function of sawmill demand in the State of Amazonas. It was found that the 34 "terra-firme" species which are commercially sawn represent an average volume of 53,819 m3/ha, of which 30% occurs in diameter classes below 40 cm and 701 in classes above 40 cm. The volume of species with a guaranteed norket represents one half of the potential volume of all commercially sawn "terra-firme" species used in the State of Amazonas. Of these commercial species, twenty ocurred in all five inventory areas, and fifteen of these accounted for 83.19% of the total volume of commercial species.

For these species in which 90% of the volume occurs in the upper diameter classes, it is suggested that seed trees be maintained to guarantee natural regeneration after timber harvesting.
