| El presente estudio se realizo con la finalidad de conocer el manejo y el uso de los acahuales en la unidad de manejo forestal 2708CE Centro, Tabasco que incluye a los municipios de (Centro, Jalapa, Centla, Macuspana, Tacotalpa y Teapa). Un total de 79 acahuales fueron ubicados, se aplicaron preguntas informales a los dueños de los predios, delegados y personas oriundas de la comunidad. Para el análisis de la diversidad de usos y determinación del índice de valor de importancia se seleccionaron tres acahuales, dos ubicados en Macuspana y uno en el Centro, por ser los de mayor representatividad en la unidad de manejo. El levantamiento de especies en cuadrantes de 10m X 50m (500m2) en cada acahual tuvo registro total de individuos, especies así como el... |

| La ejecución de cualquier actividad mitigadora de cambio climático requiere de la implementación de un mecanismo de evaluación y monitoreo que permita conocer su eficacia en condiciones específicas. Por ello, actualmente se desarrollan en México y en el mundo diversos estudios enfocados a contabilizar la captura del CO2 en bosques y selvas. En esta investigación se evaluó la aplicabilidad del modelo de contabilidad de carbono CBM-CFS3 en bosques templados sujetos a un régimen de aprovechamiento; como primer parte de la investigación fue necesario identificar la disponibilidad de datos, parámetros e información para alimentarlo, posteriormente se identificaron los mecanismos adecuados para ingresar la información al modelo CBM-CFS3, finalmente se realizó un... |

| El presente trabajo se realizó en La Mojonera, Zacualtipán, Hidalgo, con la finalidad de determinar el efecto del manejo del bosque de Pinus patula sobre la riqueza de avifauna, durante la transición invierno-primavera 2004-2005. Se definieron tres condiciones del bosque de acuerdo a su historial de manejo. La Condición Uno (C1) pertenece a un bosque no intervenido por el proceso de corta (bosque natural); la Condición Dos (C2) estuvo constituida por rodales mayores a 12 años; y la Condición Tres (C3) por rodales menores de 12 años de edad. Para el muestreo de la vegetación, se establecieron 21 parcelas de 400 m2 (20X20m). En cada parcela se etiquetaron todos los individuos de especies arbóreas con DAP≥2 cm. Se identificaron, se registró su DAP, altura,... |

| There is no one-size-fits-all approach to managing frequent-fire, old-growth forests. However, there are general guidelines to follow: 1) set objectives for both structure (tree density, diameter distribution, tree species composition, spatial arrangement, amount of coarse woody debris) and function (nutrient cycling, desired tree species regeneration); 2) prioritize treatments according to ecological, economic, and social needs and risks; 3) identify the potential treatments (natural fire, prescribed fire, silvicultural cutting) that best meet the objectives and scale of the project; and 4) implement the treatment(s). We discuss each of these guidelines in this article. |

| Adaptation of forest management practices in the context of rapid climatic and socioeconomic changes is a global concern. Stakeholders in the forest-based sector as well as policy makers need improved methods and tools to assess potential impacts of changes in management on sustainability indicators. In this special feature, we introduce a methodological framework for classification of forest management approaches in European forestry and explore how changes in forest management might affect the delivery of various ecosystem goods and services and appropriate sustainability indicators over time and space from local to continental scales. The complementary papers in this special feature explore different aspects of sustainability and risks in representative... |

| In a 15-year case study, we used the multiple streams approach (MSA) and the advocacy coalition framework (ACF) to examine a controversial industry-led proposal for increased harvest of Crown forests in New Brunswick, Canada, in an adversarial policy subsystem. Study participants were queried on their perceptions of policy problems and reasons for community attention, the relationship between science and policy, and whether policy decisions were consistent with scientific understanding. Thematic analysis was used to examine interview data for evidence of Kingdon’s MSA and Sabatier’s ACF. During public hearings of a Legislative Select Committee on Wood Supply, two competing policy alternatives emerged. The first, put forward by the... |

| Human and ecological elements of resource management systems co-adapt over time. In this paper, we examine the drivers of change in forest management policy in British Columbia since 1850. We asked: How has a set of system attributes changed over time, and what drivers contributed to change when it occurred? We simultaneously examined a set of three propositions relating to drivers and dynamics of policy change. We find that factors contributing to the level of impacts, like technology, changed substantially over time and had dramatic impacts. In partial contrast, the institutions used to exercise control (patterns of agency and governance) remained the same until relatively recently. Other system attributes remained unchanged (e.g., the concept of... |

| In Thailand, mangrove forests are claimed for state management, although it is widely recognized that coastal communities access and manage those forests. Skepticism persists within Thai government circles about whether coastal villages can sustainably manage and protect mangroves. This research presents evidence of successful mangrove conservation and management by two coastal villages in Trang province, southern Thailand. Using interdisciplinary methods including interviews, discussions, quantitative forest surveys, and institutional analysis, we describe the history of how these two communities gained rights to manage the mangrove forests, and the subsequent positive biological outcomes associated with their management. Local villages have crafted and... |

| Boreal forests, which are often undeveloped, are a major source of raw materials for many countries. They are circumpolar in extent and occupy a belt to a width of 1000 km in certain regions. Various conifer and hardwood species ranging from true firs to poplars grow in boreal forests. These species exhibit a wide range of shade tolerance and growth characteristics, and occupy different successional positions. The climate is subarctic, with short growing seasons, and the soils are shallow. Both wildfires and timber harvesting play an important role in shaping the structure and composition of boreal forests. Both uneven-aged and even-aged silvicultural systems can be used to produce commercial harvests, but systems can also be designed to meet a variety of... |
