Abstract	Spatial, Temporal, and Economic Constraints to the Commercial Extraction of a Non–Timber Forest Product: Copaíba (Copaifera spp.) Oleoresin in Amazonian Reserves. The increasing prevalence of government– and NGO–sponsored programs to encourage commercial non–timber forest product (NTFP) extractivism in the humid tropics has highlighted the need for ecological and socioeconomic appraisal of the viability of extractive industries. We adopted a novel integrative approach to examine NTFP resource potential and produced credible landscape–scale estimates of the projected value of an economically important Amazonian NTFP, the medicinal oleoresin of Copaifera trees, within two large contiguous extractive reserves in Brazilian Amazonia. We integrated results derived from previous spatial ecology and harvesting studies with socioeconomic and market data, and mapped the distribution of communities within the reserves. We created anisotropic accessibility models that determined the spatial and temporal access to Copaifera trees in permanently unflooded (terra firme) and seasonally flooded (várzea) forests. Just 64.9 % of the total reserve area was accessible, emphasizing the distinction between the actual resource stock and that which is available to extractors. The density of productive tree species was higher in the várzea forests, but per–tree productivity was greater in the terra firme forests, resulting in similar estimates of oleoresin yield per unit area (64–67 ml ha$^{–1}$) in both forest types. A greater area of the várzea forests was accessible within shorter travel times of ≤250 minutes; longer travel times allowed access to increasingly greater volumes of oleoresin from the terra firme forests. The estimated total volume of oleoresin accessible within the two reserves was 38,635 liters for an initial harvest, with projected offtake for a subsequent harvest falling to 8,274 liters. A household that extracted just 2 liters of oleoresin per month could generate 5 % of its mean income; market data suggested that certification could increase the value of the resource fivefold. Our approach is valuable in that it incorporates a range of methodologies and quantitatively accounts for the numerous constraints to the commercial viability of NTFP extraction. Restrições Espaciais, Temporais, e Econômicas na Exploração Commercial de um Produto Florestal Não–Madeireiro: Óleoresina de Copaíba (Copaifera spp.) em Reservas da Amazônia. A prevalência emergente de programas de ordem governamental ou não que promovem a exploração comercial de produtos florestais não–madeireiros (PFNMs) tem acentuado a importância de uma avaliação quantitativa da viabilidade demográfica destas indústrias extrativistas. Nós adotamos uma nova abordagem integradora para examinar o potencial de produção de um PFNM, gerando estimativas numa escala de grandes paisagens do valor econômico da óleoresina de copaibeiras (Copaifera spp.) em duas reservas contíguas de uso sustentável na Amazônia brasileira ao longo do Rio Juruá. Estas estimativas integram resultados derivados de estudos da ecologia de paisagem, acessibilidade física dos coletores, valor socioeconômico e de mercado do produto, e distribuição espacial da população humana nas reservas. Modêlos de acessibilidade anisotrópica foram criados para determinar o padrão de acesso espaço–temporal à copaibeiras tanto em floresta de terra firme quanto floresta sazonalmente inundável (várzea). Somente 64.9 % da área total das reservas eram acessíveis a extratores, enfatizando a diferença entre o volume total do estoque e a proporção deste volume que está realmente disponível. A densidade de árvores produtivas foi mais alta em floresta de várzea, mas a rentabilidade per capita foi mais alta em florestas de terra firme, resultando em taxas de usofruto semelhantes entre estes dois tipos de floresta (64 e 67 ml ha$^{–1}$). Uma área mais extensa de várzea permanecia acessível dentro de um raio de busca de ≤250 min; enquanto que raios de busca mais amplos permitiam extração de maiores volumes de óleoresina em áreas de terra firme. O volume total de óleoresina acessível dentro das duas reservas foi de 38.635 litros na primeira colheita, com uma projeção de mais 8.274 litros em coletas subsequentes. Domicílios extraindo mensalmente somente 2 litros de óleoresina podem gerar 5 % da sua renda média, e dados de mercado sugerem que uma iniciativa de certificação florestal pode aumentar o valor desta atividade extrativista pelo menos cinco vezes. A nossa abordagem é útil do ponto de visto de manejo de recursos pois ela incorpora várias metodologias que consideram quantitativamente as limitações da viabilidade comercial da exploração de um PFNM em regiões de floresta tropical.
