Abstract

ln this study, thc potential for sustainable forcstry is evaluated for the Eastcrn Arnazonian rcgion of Paragominas, Pará. We show that forest managcment may allow future timber volume and cornposition yields similar to that of the first harvest. With a rotation time between 20 to :>0 years, the timber yield with management may be two and one half times greatcr than that without managcment. Without forest managcmcnt, a wider variety of species and a largcr harvest area will be rcquired in order to achieve constant harvest volumes into the future. Currcntly, incentives are lacking for Iorest management as public poliey allows the payment of a Iorestry taxo equivalent to one third the present valuc 01′ a standard management protocol, in place of actual management. The long term instability of timber markets also tends to discourage investrnents in forest management. Policy initiatives that may stimulate active forest management inelude the equalization of forestry taxes with management costs, eliminating the less expensive and easier option of merely paying a nominal forestry taxo Revenues írom the forcstry tax may be used to fund forestry extension scrvices in the region.
