Conteúdo: 	Conservation of degraded forests is a challenging issue in the tropics, since the maintenance of environmental services and economic demands must be conciliated. Environmental services must be conserved while degraded tropical forests are demanded to be competitive against more financially profitable land uses as crop fields and pastures. The objective of this study was to evaluate productivity and financial profitability of enrichment planting in degraded forests. Seeds of Schizolobium parahyba var. amazonicum were planted in logging gaps of a 108-ha degraded forest in southeast Pará (Brazil) in February 1995 . After 13 years (2008), S. parahyba presented a volume increase of 3.1 m3 for individuals 25 cm in DBH. More than 30% of the planted seeds were able to germinate, establish, and grow up to sizes 25 cm in DBH. A cost-benefit analysis through Net Present Value (NPV) and a sensitivity analysis with different interest rates were performed to compare financial profitability of the treated and control area under roundwood and laminated plus sawnwood production. Enrichment planting using S. parahyba seeds presented higher NPVs in the treated than in control area for all simulations, except roundwood under interest rate of 9% per year.
