| In last decades, the increase of Eucalyptus plantations was relevant in Brazil, especially in the global scenario. Several studies showed that these cultures, especially those guaranteed by certification mechanisms, can bring social and environmental benefits. This paper presents data collected in the period 2002-2011, where we show richness data of plants, birds and mammals in eucalyptus plantation farms in Brazil. It is discussed the importance of these areas to biodiversity conservation, where have been recorded 1,320, 620 and 55 species of woody plants, birds and medium and large mammals, respectively. It was registered the occurrence of endangered plant species in the plantations understory: Araucaria angustifolia, Couratari asterotricha, Buchenavia... |

| A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere; i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest... |

| 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... |

| This report summarizes preliminary findings of the Mexican National Database and Community Survey Project which examines linkages between institutional characteristics in Mexico’s common property forestry sector and economic and environmental outcomes. Framing the Mexican agrarian community as a unit of analysis characterized by its history, individual members, resources, civic structure and property rights, we use institutional economic analysis to motivate project design and research on three aspects of Mexican community forestry governance: first, how communities have engaged forest resources to participate in forestry markets; second, how internal models of forestry management are reflect historical circumstances and practices, policy trends and... |

| Women’s participation in decision making at the user-group level and in forest committees has been demonstrated to have a positive impact on forest sustainability. For example, women’s participation enhances forest regeneration and reduces illegal harvesting through improved monitoring. Their presence in forest user groups increases the groups’ capacity to manage and resolve conflict, which in turn increases the likelihood that resource users will comply with and respect harvesting and use rules. These insights have been especially useful in informing policy and project interventions designed to strength and amplify women’s participation. This paper adopts a cross-national approach and employs quantitative techniques to analyze the relative... |

| Corruption in the forest sector of Swat, Pakistan is impairing the sustainable management of forest. We analyze corruption in a case study setting against the backdrop of the reform options that are most often cited as possible solutions. As we highlight in this study, the crime and punishment approach is not feasibly implemented if the overall institutional environment is weak. Since countrywide overhaul of corruption through sweeping reform programs, the other reform approach, is a difficult and lengthy task, there is a need for an alternative kind of reform. In the case of a corruption-ridden centralised forest management regime, institutional reform should move away from enforcement of existing institutions and promote communal management of natural... |

| This paper maintains that the Forest Service (FS), as an institution, is in deep trouble. It argues that the FS today is an agency without a unique mission and without a supporting constituency. For the FS to be viable in the future it needs a distinct well-defined mission and a committed constituency. The distinct mission needs to be generally supported, or at least not opposed, by most of the American people. The constituency needs to be committed to the FS to the extent that it will provide major support in the Congress for FS budgets. The paper identifies some potential candidates for a mission for the National Forest System (NFS), e.g., as a biological reserve or as a provider of forest recreation. Another potential paradigm could be that of the... |

| ABSTRACT The impact of intensive management practices on the sustainability of forest production depends on maintenance of soil fertility. The contribution of forest residues and nutrient cycling in this process is critical. A 16-year-old stand of Pinus taeda in a Cambissolo Húmico Alumínico léptico (Humic Endo-lithic Dystrudept) in the south of Brazil was studied. A total of 10 trees were sampled distributed in five diameter classes according to diameter at breast height. The biomass of the needles, twigs, bark, wood, and roots was measured for each tree. In addition to plant biomass, accumulated plant litter was sampled, and soil samples were taken at three increments based on sampling depth: 0.00-0.20, 0.20-0.40, 0.40-0.60, 0.60-1.00, 1.00-1.40,... |

| 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... |

| Seed dispersal of Hymenaea courbaril was studied by following the fate of 585 seeds embedded with small magnets and set in displays in and near a logged strip in rain forest in the Peruvian Amazonian. Mammals took fruits from all displays, which were located in the forest, edge, and cleared strip. Overall removal rates were low - a median of 8.1 fruits / month from displays maintained with 8-10 fruits - but were higher in August than in earlier months. Most fruits were dropped near the display or had their seeds eaten, but > 13% were successfully dispersed. Most of the dispersed seeds were buried, which increases probability of germination. Maximum dispersal distance of live seeds was 12.1 m (median 3.1 m), but other magnets were transported up to 34 m,... |

| Nutrient recycling in the forest is linked to the production and decomposition of litter, which are essential processes for forest maintenance, especially in regions of nutritionally poor soils. Human interventions in forest such as selecttive logging may have strong impacts on these processes. The objectives of this study were to estimate litterfall production and evaluate the influence of environmental factors (basal area of vegetation, plant density, canopy cover, and soil physicochemical properties) and anthropogenic factors (post-management age and exploited basal area) on this production, in areas of intact and exploited forest in southern Amazonia, located in the northern parts of Mato Grosso state. This study was conducted at five locations and the... |
