| ABSTRACT: The application of optimization methods to forest management has given rise to a successful line of investigation in recent decades. However, there have been few publications associated with the application of these techniques to the management of industrial forest plantations (those with short or medium rotations, always less than 50 years), which consider the important role played by these forest systems in the supply of diverse goods and services. This study presents an overview of this literature which, by analyzing 67 articles published in journals contained in the ISI Web of Science, highlight, among other aspects, the techniques employed, their evolution, their planning type (strategic, tactical or operational), the functional objectives... |

| A fenntarthatóság mérése, de definiálása is nehézkes a jövőre vonatkozó feltételezések bizonytalansága miatt. Korlátozott következtetések vonhatók le pl. a „kereslet és kínálat” összehasonlításának elvén alapuló, egyre közismertebb ökológiai lábnyomból, vagy más, a fenntarthatóság bizonyos aspektusait részletesebben jellemző indikátorok tényleges értékeinek és az előre elvárt értékek összevetéséből. Ilyen, fejlődő, korlátozott lehetőségeket nyújtó indikátorrendszer jött létre az erdőgazdálkodásban. A rendszer használatát nagymértékben korlátozza, hogy megalapozatlan az, hogy hány, illetve mennyire specifikus vagy mennyire aggregált indikátorokat alkalmaznak, és hogy az indikátorok mért értékeit hogyan értelmezik. Emiatt az indikátorértékek értelmezésében... |

| Individual actions to avoid, benefit from, or cope with climate change impacts partly shape adaptation; much research on adaptation has focused at the systems level, overlooking drivers of individual responses. Theoretical frameworks and empirical studies of environmental behavior identify a complex web of cognitive, affective, and evaluative factors that motivate stewardship. We explore the relationship between knowledge of, and adaptation to, widespread, climate-induced tree mortality to understand the cognitive (i.e., knowledge and learning), affective (i.e., attitudes and place attachment), and evaluative (i.e., use values) factors that influence how individuals respond to climate-change impacts. From 43 semistructured interviews with forest managers... |

| A significant challenge in the assessment of forest management outcomes is the limited ability to compare forest conditions quantitatively across ecological zones. We propose an approach for comparing different forest types through the use of reference forests. We tested our idea by drawing a sample of 42 forests from the Midwest USA, Mexico, Guatemala, Honduras, Brazil, Bolivia, Uganda, and Nepal. We grouped these forests by shared characteristics and selected a reference forest to serve as a baseline for each forest type. We developed an index of disturbances using ratios of several forest measurements to assess differences between each study forest and its reference forest. None of the study forests was known to have been impacted by major natural... |

| Forest degradation is broadly defined as a reduction in the capacity of a forest to produce ecosystem services such as carbon storage and wood products as a result of anthropogenic and environmental changes. The main causes of degradation include unsustainable logging, agriculture, invasive species, fire, fuelwood gathering, and livestock grazing. Forest degradation is widespread and has become an important consideration in global policy processes that deal with biodiversity, climate change, and forest management. There is, however, no generally recognized way to identify a degraded forest because perceptions of forest degradation vary depending on the cause, the particular goods or services of interest, and the temporal and spatial scales considered.... |

| O Acre, com área de 152.522 km2 e uma cobertura vegetal de quase 90% apresenta forte aptidão e tradição extrativista. Contudo, modelos de produção agropecuária e de exploração extrativa da madeira, caracterizada pela extração seletiva, têm ocasionado elevados danos ao meio ambiente florestal, em particular, nas áreas de reserva legal onde as derrubadas continuam avançando. Um dos elementos que mais tem contribuído para que isso aconteça é o fato de não ser atribuído nenhum valor econômico à floresta. Na visão do produtor, essas áreas são consideradas como impedimento para obter maior renda, pela expansão daquelas destinadas à agropecuária. Neste aspecto , a exploração de madeira certificada, oriunda de projetos comunitários de manejo florestal em áreas de... |

| 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... |

| This paper analyzes the relationship between rural poverty and forest land management for the case of charcoal production under slash-and-burn agriculture. An optimal control model is used to determine how a representative household makes decisions about the allocation of labor and about the forest areas to exploit. In turn, these decisions affect the renewable resource base available to the community. The proposed optimal control model for charcoal production is based on the Pascual and Barbier (2007) model of slash-and-burn agriculture. This theoretical model is calibrated with data from the community of Chunkanán, Campeche, Mexico. The simulation and comparison of the traditional slash-and-burn approach to forest management with the Forest Management... |

| 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,... |
