Abstract
The importance of non-timber forest products (NTFPs) to rural income was examined in a highland community in the Sierra de Manantlán Biosphere Reserve, Jalisco-Colima, Mexico. Rapid Rural Appraisal (RRA) techniques were used to interview 70% of households in the community of El Terrero. Of the nine plant species identified as NTFP sources, the two principal species traded by the community were tila (derived from the flowers and fruits of the tree Ternstroemia lineata), and blackberry (Rubus spp.). Collecting and selling of NTFPs was almost exclusively undertaken by women, with 80% of respondents participating. NTFP sale ranked as the most important source of cash income for 30% of women interviewed, and either second- or third-most important for the remainder. The research examined harvesting impact on populations of T. lineata, an understory tree species characteristic of cloud forest, which this was assessed in the four most-frequented collecting sites. Our results suggested that current harvesting approaches appear to be sustainable, although 95% of the women interviewed reported a decline in resource availability within the last 15 years, apparently resulting from illegal cutting. Suggestions are made with respect to the sustainable development of NTFP resources to help alleviate poverty within the Reserve.
Resumen
Se evaluó la importancia de los productos forestales no maderables (PFNMs) en el ingreso familiar de un ejido ubicado en una zona montañosa de la reserva de la biósfera de Manantlan, Jalisco—Colitna, México. Se utilizaron técnicas participativas como entrevistas al 70% de las familias de el ejido “El Terrero.” De las nueve especies de plantas identificadas comofuentes de PFNMs, las dos más comercializadas por la communidad fueron tila (órganos frutales del arbol Ternstroemia lineata) y zarzamora (Rubus spp.) La colecta y venta de PFNMs fue casi exclusivamente llevada por mujeres, con una participation del 80%. La venta de PFNMs fue la principal fuente de dinero para el 30% de las mujeres entrevistadas, y el segundo o tercero en importancia por las demás. La investigatión examinó el impacto de la extractión en poblaciones silvestres deT. lineata (una especie de bosque nublado), la cual fue evaluada en cuatro de los sitios de colecta más frecuente. Nuestros resultados sugieren que el nivel y manera de extractión parecen ser sustentable; aunque el 95% de las mujeres entrevisada han notado que en los últimas 15 años la cantidad de recursos naturales ha bajado a causa de la extractión ilegal. Se hacen sugerencias en cuanto al desarollo sustentable de estos PFNMs, para ayudar a disminuir la pobreza dentro de la reserva.
