Abstract: Researchers concerned with sustainable management of forests in the tropics have argued that road to improved stewardship forest resources is transfer responsibility local communities who get their livelihoods from them. On other hand, conservationists declared only way stem tide deforestation place as many tracts possible under strict protection. In this context, Mexico presents a national laboratory for studying social and ecological benefits delivering people. As little‐noticed...
Despite regional deforestation threats, the state of Quintana Roo has maintained over 80% its territory in forests. Community forest management (CFM) played a pivotal role cover and biodiversity conservation region. In this article, we present institutional, socioeconomic environmental conditions under which community-based been consolidated tropical Roo, occupies eastern half Mexico’s Yucatan Peninsula. With focus on for timber other market-based development strategies, then examine...
La reforestación en México es importante para recuperar la producción de las áreas deforestadas y degradadas mantener los bosques comerciales. Sólo 40% tienen un nivel aceptable supervivencia. Las características plántulas que se utilizan, incluyendo relación tallo/raíz plántula, deben tomarse cuenta lograr resultados deseados (alta supervivencia buen crecimiento campo). Se describen Swietenia macrophylla King, Cedrela odorata L. Tabebuia rosea ( Bertol.) DC bajo dos densidades (100 50...
Abstract Mahogany (Swietenia macrophylla King) is the single most important commercial tree species in forests of state Quintana Roo, Mexico. regeneration has been associated with natural disturbances that increase understory light levels. A study to analyze effect overstory removal on seed germination and early seedling survival growth mahogany was conducted. Twenty-five 0.2 ha plots were treated create different levels then seeded. Two seeding methods used, dibbling dropping. Dropping used...
La tendencia creciente de impactos humanos y huracanes sobre las selvas la Península Yucatán, se ha constituido en una amenaza para su sobrevivencia. Esto es gran relevancia, considerando que el manejo selva, actividad primordial conservación generación ingresos poblaciones locales. Este escenario fundamentó presente estudio realizado selva Noh-Bec, Quintana Roo, impactada por huracán “Dean” (2007). El propósito fue identificar los factores tuvieron influencia magnitud daños ocasionados...
Un problème clé dans la gestion de production bois d’œuvre est d’assurer régénération d’espèces ayant une valeur commerciale, telles que Swietenia macrophylla King (acajou), ce qui nécessite connaissance approfondie des espèces concernées. Cet article rend compte résultats du semis direct l’acajou trois champs cultivés sur brûlis au cours dernière année culture, à Betania, région Quintana Roo Mexique. Dans chaque champ, 121 sites ont été identifiés parcelle 0,25 ha, et cinq graines semées...
The management of mahogany (Swietenia macrophylla King) in the Yucatan peninsula Mexico is based on assumption that diameter at breast height (dbh) growth averages 0.73 cm yr 1 so will reach a harvestable dbh 55 75 years. In 2002, transects were established forested area Laguna Kana ´ Quintana Roo, Mexico. All with > 10.0 measured and marked. 2008/2009, trees remeasured, tree, soil, site characteristics competition around each tree recorded. Of 499 studied, average surviving was 0.22 , far...

 Aunque muchos árboles tropicales se extraen con fines comerciales, son escasas las investigaciones que han abordado el estudio de su regeneración, tasas crecimiento y técnicas sustentables para aprovechamiento. La carencia este tipo información representa una mayores debilidades los programas manejo forestal, en regiones méxico. Lo anterior refleja, por ejemplo, la caoba (Swietenia macrophylla) cedro (Cedrela odorata) están cada vez menos disponibles selvas Quintana roo. un...
Abstract A study of the effect different levels basal area removal on stand and tree growth was established in a second forest Quintana Roo, Mexico. In five 0.5 ha plots (subdivided into 10 × m2 plots), data were collected periodically for 15 years used to estimate diameter 30 tropical species. Net per hectare almost 0, -0.1% yr-1. For surviving trees only, 1.6% year. On strongly correlated initial when only considered. Maximum average rate 0.31 cmy-1 (Swietenia macrophylla King). Most...
En la comunidad de San Pablito en Sierra Norte Puebla, el árbol Trema micrantha (jonote) proporciona 80 % corteza utilizada manufactura del papel amate, una las artesanías más importantes y conocidas México. La se dedica su totalidad a producción amate; sin embargo, abastecimiento es irregular, insuficiente proviene lugares lejanos al centro productor. El presente estudio tiene tres objetivos: evaluar interés personas comunidades vecinas para aumentar árboles jonote, documentar prácticas...
En Amérique tropicale, la régénération de l’acajou à grandes feuilles, Swietenia macrophylla King, essence commerciale majeure, est problématique en raison ses caractéristiques fructification et dispersion sa faible tolérance l’ombre réaction l’exploitation forestière. Dans l’État Quintana Roo, au Mexique, les brûlis abandonnés offrent d’excellents espaces pour l’établissement jeunes plants, mais un moyen effi- cace permettant d’assurer survie des semences reste identifier. La présente étude...
