Forest policy and management are subject to various and often conflicting demands, which internationally have led to distinct policy responses and related management paradigms. These range from a strong focus on commodity production complemented by economic rationalities – e.g. focusing on plantations – to community-based or social forestry approaches highlighting local participation and stakeholder engagement, to a focus on ecosystem services and conservation. A major challenge involves the potential orientation of the overall forest policy and management paradigm either towards integrating manifold demands more or less evenly across an area, or towards dividing the land base into forest areas with different management priorities. The specific reconciliation and integration of both sides of the spectrum have been at the centre of scientific and political discussion on forest policy and management for several decades.In this context, the “German model” of integrative and multifunctional forest management has received international attention. It is regarded as an example for integrating diverse (societal and ecological) demands into a timber-production-oriented management approach. At the same time, the model's primary focus on timber production has been criticised by some.In this paper, we analyse the political dimension of the German model by tracing the birth and evolution of the so-called LÖWE programme, a much noticed governmental forest management programme in the German state of Lower Saxony. LÖWE has frequently been presented as a particularly successful example of multifunctional forestry. We first assess the specific societal and political circumstances that led to the establishment of the programme 20 years ago. Subsequently, we assess its political function in forest policy debates about various demands on Lower Saxony's public forests. We show that the evolution of the programme can be interpreted in two distinct but non-exclusive ways. On the one hand, LÖWE was a strategic success story for the Forest Service because it aligned (and also appeased) conflicting demands in line with the changing political priorities. On the other hand, it also embodied a learning process towards environmental policy integration. By underlining LÖWE as an example of the German model of integrative multifunctional forest management, we reiterate the strategic importance of this model in the German context and also highlight future challenges and related research needs.  相似文献

Tropical forests could satisfy multiple demands for goods and services both for present and future generations. Yet integrated approaches to natural forest management remain elusive across the tropics. In this paper we examine one combination of uses: selective harvesting of timber and non-timber forest product (NTFP) extraction. We analyze the current status of this combination and speculate on prospects and challenges regarding: (i) resource inventory, (ii) ecology and silviculture, (iii) conflict in the use of multipurpose tree species, (iv) wildlife conservation and use, (v) tenure, and (vi) product certification. Our conclusions remain preliminary due to the relative paucity of published studies and lessons learned on what has worked and what has not in the context of integrated management for timber and NTFPs. We propose at least three ways where further research is merited. One, in improving ‘opportunistic’ situations driven by selective timber harvesting that also enhance NTFP values. Two, to explicitly enhance both timber and NTFP values through targeted management interventions. Three, to explicitly assess biophysical, social, regulatory and institutional aspects so that combined benefits are maximized. Interventions for enhancing the compatibility of timber and NTFP extraction must be scaled in relation to the size of the area being managed, applied timber harvesting intensities, and the dynamics of multi-actor, forest partnerships (e.g., between the private sector and local communities). In addition, training and education issues may have to be re-crafted with multiple-use management approaches inserted into tropical forestry curricula.  相似文献

Private native forests in Australia perform a dual production and conservation role, providing an important source of timber, and complementing formal conservation reserves. A comparison of policies for private native forests in New South Wales, Queensland, Victoria and Tasmania illustrates the scope for timber harvesting, the provision for environmental values, and initiatives for responsible and sustainable forest management. The sustainable management of Australia’s forests requires initiatives by both government and landowners to accommodate changes in community attitudes, new management strategies, integrated catchment management principles and both commercial and non-commercial opportunities for forest use. Of all of the Australian states, New South Wales has the most restrictive laws in terms of forest management and harvesting. Queensland and Victorian legislation have a more commercial focus, while Tasmania has a balance of both environmental and commercial objectives. The duty of care for private native forests is a responsibility that falls to the landholder, and while this should be enforced by legislation, the private provision of community benefits requires both recognition and reward. The presence or absence of incentives potentially determines the effectiveness of forest codes of practice.  相似文献

Russian forests are of high importance for the Russian economy, the European wood market, for nature conservation, and for carbon sequestration. However, the ongoing changes in forest management and administration in Russia led to uncertainty about forest ownership, wood harvesting levels, and long-term impacts of alternative management plans. Therefore, better insight in their current and future state is highly desirable. We present a study for the Leningrad region forests in which alternative management regimes for wood production and nature conservation values are balanced in varying ways. The total forest land area in the Leningrad region forest fund is 4.8 million ha. Coniferous species dominate and due to the natural succession occurring, the forests are divers in vertical structurally.

A timber assessment model was used to project the forest until 2040. Five forest management scenarios were run. Special attention was paid to a scenario that simulates recovery of the Russian forest sector in combination with the incorporation of a ‘set-aside for nature conservation’ policy. All scenarios showed that recovery of the forest sector in the Leningrad region is biologically feasible. A sustainable continuous annual production of 10.6 million m3 per year (2.8 m3 ha−1 per year) by 2040 was found. The ‘Recovery with Nature Conservation’ scenario showed that recovery of the forest sector in combination with the establishment of set-aside areas is very well feasible. It was possible to set aside 28% of the forest area for nature conservation while still developing a forest sector to a production level higher than that achieved in the late eighties.

The timber assessment model applied was not specifically designed to incorporate nature-oriented forest management. We, therefore, discuss ways of improving the required methodology to analyse long-term effects of nature-oriented forest management in Europe.  相似文献

There is increasing pressure to manage forests for multiple objectives, including ecosystem services and biodiversity, alongside timber production. However, few forests are currently co-managed for timber and wildlife, despite potential economic and conservation benefits. We present empirical data from a commercial Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) production system in southern Norway in which moose (Alces alces) are an important secondary product. Combining long-term hunting and forestry records, we identified temporal variation in clear-felling over the past five decades, peaking in the 1970s. Herbicide treatment of regenerating stands and a fivefold increase in moose harvest has lead to a reduction in availability of successional forest per moose of >90 % since the 1960s. Field estimates showed that spraying with the herbicide glyphosate reduced forage availability by 60 and 96 % in summer and winter, respectively, 4 years after treatment. It also reduced moose use and habitat selection of young spruce stands compared with unsprayed stands. Together these lines of evidence suggest that forest management led to an increase in moose carrying capacity during the 1970s and a subsequent decline thereafter. This is likely to have contributed to observed reductions in moose population productivity in southern Norway and is counter to sustainable resource management. We therefore call for better integration and long-term planning between forestry and wildlife management to minimise forest damage and the development of large fluctuations in ungulate populations.  相似文献

The Government of Indonesia (GoI) and the European Union (EU) have signed a Voluntary Partnership Agreement on Forest Law Enforcement Governance and Trade (FLEGT-VPA), which aims to prevent illegal timber products from entering the EU. This agreement recognizes a certification for timber products exported from Indonesia based on FLEGT-VPA standards and implemented through the timber legality verification system, Sistem Verifikasi Legalitas Kayu (SVLK). While the implementation of SVLK complies with the FLEGT-VPA, it has not dissolved pre-existing national systems for forest management and timber trade. Implementing SVLK standards amid multiple forest regimes causes redundancy of administrative procedures in forest management and timber trade in Indonesia. This redundancy, in turn, leads to decrease in cost efficiency, weak legitimation, and low effectiveness of the system, especially in community forests.  相似文献

Sustainable forest management is the process of managing forest to achieve one or more clearly specified objectives without diminishing the forest’s ability to continue providing goods and services in perpetuity. In this paper, we show how the African Timber Organization/International Tropical Timber Organization principles, criteria and indicators for the sustainable management of African forests can help timber companies assess their progress towards this goal in Gabon. Through a partnership between International Tropical Timber Organization project PD 124/01 Rev. 2(M), the World Wildlife Fund, and the ministry responsible for forests in Gabon, audits were conducted between 2012 and 2014 to evaluate the implementation of sustainable forest management in 14 forest concessions in Gabon. In general, results show that Principle 4, linked to the well-being of workers and local populations, proved the most difficult principle to implement, while Principle 3, dealing with maintaining ecological functions, was the least problematic. A number of companies were found to be experiencing significant difficulties in implementing management plans. It is also clear that independent forest certification has become a key element for ensuring the successful implementation of sustainable forest management.  相似文献

The goal of nature conservation is often implemented on productive forest land largely by means of forest certification – a market-driven, voluntary system of third-party verification of the fulfilment of specific goals. This study assesses how certification requirements are being implemented in various organisations in the forest sector at various levels, and the problems and opportunities identified at each level in order to implement the requirements of the standard. Based on interviews with 34 stakeholders in Sweden, the study demonstrates that forest certification is a communication issue: it places great demands on communication or “information logistics” between different parts of the felling and forest management chain, from the top management to the contractor in the field. Integration with environmental performance systems, clarity in the division of responsibility, formalisation of requirements for forest planning and further integration of a culture of continuous improvement and internal reporting could support implementation of the certification system.  相似文献

Mountain forest management is, and has always been, multipurpose-oriented. It should provide for private goods, such as timber, as well as public goods, such as protection against natural forces. This paper investigates private, state and common property regimes in terms of theoretical managerial performance, since empirical studies are scarcely available. Private property rights are sufficient for the production of private goods, whereas public goods have to be safeguarded by state intervention. The performance of state property regimes depends on objectives set by society and their implementation by public officials. Whereas state intervention in private and public property regimes in mountain forests is a necessary condition for multipurpose forest management, common property regimes would be less dependent on it. Usually, the rights holders of common property regimes use mountain forests for the production of both private and public goods. One can conclude that common property regimes are promising for the multipurpose management of mountain forests. In practice, however, common forest property regimes in Switzerland and Austria have become very dependent on public support. Research is recommended in order to investigate into the underlying reasons.  相似文献

We discuss the extent of compatibility of timber and non-timber forest product (NTFP) extraction in two neotropical localities from biophysical, social, and institutional perspectives: the community concession forests of the Petén, Guatemala, and extractivist communities in northern Bolivia. In both localities, timber is harvested via reduced-impact logging (RIL) practices. In Guatemala, the main NTFP extracted is foliage from the understory xate palm (Chamaedorea spp.); in northern Bolivia, the fruits of the Brazil nut tree (Bertholletia excelsa). The Guatemalan case suggests a relatively high degree of compatibility due to low timber harvesting intensities, coupled with temporal, spatial, and social segregation of xate extraction in a well-defined land tenure system. In northern Bolivia, forest management regulations pay little attention to NTFPs and land tenure issues and related conflict complicate efforts to limit timber harvesting impacts on Brazil nut trees. The introduction of timber management plans overlain on customary property rights systems in which the extraction of Brazil nut is organized could undercut its management system. The two case studies suggest that specific legislative, education, and project interventions may help to promote the compatibility of timber and NTFP extraction and management. These include formal training of foresters on NTFP ecology and management while taking into account the perspectives of multiple stakeholders in the design of management plans. Tropical forest users, research managers, and policy makers will also better understand the need for integrated management of timber and NTFPs, if the trade-offs and potential economic benefits from NTFP extraction are clarified.  相似文献

The heterogeneous nature of non-industrial private forest (NIPF) owners and the challenge this heterogeneity presents for effective policy and program design and delivery is widely recognised. Understanding the socio-economic and motivational differences between various types of landowners will better equip policymakers and forest extension professionals to design policies and programs that efficiently promote private sector timber production and forest conservation outcomes. The purpose of this study was to develop a survey-based empirical typology of Tasmanian NIPF owners based on their stated objectives of forest ownership and to relate owner type to a range of observable property and owner characteristics as well as to timber harvesting and forest management behaviour. Using principal component analysis (PCA) followed by means cluster analysis, four distinct groups are identified: income and investment owners, non-timber output owners, agriculturalists, and multi-objective owners. Members of these groups are found to differ significantly in terms of their personal and property characteristics, as well as their timber harvesting and management behaviour. For example, members of the non-timber output owners, who are motivated solely by objectives related to the production and protection of the non-timber outputs of forests, have similar proportions of timber on their property, but are less likely to have harvested timber from their property, than all other groups.  相似文献

In “West Development” of China, one of the most important activities is the Natural Forest Protection Program, designed to swiftly convert the focus of management and utilization of the natural forests from a timber orientation towards forest conservation, sustainable management and environmental protection. The project covered almost all the arid and semi-arid regions in Northwest region. Accompanying this great campaign this paper studied the conservation and restoration model of degraded ecosystems in arid and semi-arid lands in Northwest China. The past practices have resulted in considerably natural forest degradation and loss through land conversion (primarily for agriculture), over-harvesting, inadequate reforestation and lack of protection. The consequences have been the loss of soil and water resources, diminished timber production capacity on a sustainable basis, and environmental losses. This paper applied Aronson’s restoration model and proposed the conservation, restoration, re-allocation and preservation program for the implementation of environmental improvement and natural forest conservation.  相似文献

The Republic of Korea (ROK) started to experience forest transition in the 1960s in spite of severe deforestation and forest degradation by the mid 1950s. This ROK case followed the state policy pathway to forest transition. This study interpreted the reforestation policy of the multiple sectors in ROK with the theory of environmental policy integration. ROK has attempted an integrated policy program for reforestation, land management and social development as an innovative approach to solving the problem of flood and erosion due to deforestation while pursuing economic growth. This integrated approach to reforestation of ROK was implemented in three pillars of action: 1) coordinated national plans, 2) collaboration among the governmental branches, and 3) organizational reformation. The integrative approach helped the reforestation policy to be implemented successfully. The case of policy integration for reforestation in ROK is a good example demonstrating that policy integration should be a principle of forest policy design and implementation. The Korean experience could be informative to developing countries experiencing deforestation for design and implementation of forest policy to avoid deforestation and achieve forest transition.  相似文献

An overview of the forestry sector in Costa Rica was undertaken to determine whether the existing management practices of timber resources hold the potential to meet the country's demands for timber in the immediate decades to come, and to identify changes that might be needed in the management of forested lands. To meet these goals, we examined the present status and potential future contribution of the two newest forest sectors: the management of natural forest and plantation forestry. Rcsults indicate that the present management of Costa Rica's timber resources does not hold the potential to meet the country's demands for timber for more than the next ten years without severe loss of its forests. Substantial progress is occurring, but at an insufficient rate. Moreover, despite the considerable headway made in conservation in recent years, the rate of deforestation remains high. A number of factors limit advancement in natural forest management and plantation forestry, both of which have the potential to deaccelerate deforestation. In natural forest management, constraints are the rate at which forests are being brought under management, lack of budgetary provisions for fiscal incentives to private owners who alone cannot be expected to bear the cost of benefits of natural forest management that are national or even global in their distribution, and the weak infrastructure, extension services and research support to meet management goals. In the case of plantation forestry, the capability of this sector to produce commercial timber is not known. Moreover, inadequate management and extension services together with the misuse of the incentive system by private owners is likely to limit the potential of plantations. Institutional constraints include outdated legal and bureaucratic framework, market interventions, absence of clear policy toward natural forest management and plantation forestry, poor investment in infrastructure, extension and research support, and inadequate interaction among various agencies responsible for the development of the forestry sector. Such institutional constraints have allowed the proliferation of disincentives against the development of a sustainable timber sector. If the Costa Rican government's objective is to encourage sustainable forestry, it must first clearly articulate the policy and then create the appropriate legal, economic and institutional framework for implementation of the policy. Costa Rica, with its enlightened public administration system, vast technical and scientific knowledge about its forest ecosystem and extensive assistance from international organizations, must succeed, otherwise prospects for sustainable forestry in thc less fortunate tropical countries would be bleak.  相似文献

Sal (Shorea robusta Gaertn. f.) forests cover over 11 millionha in India, Nepal and Bangladesh, and these forests are conventionallymanaged for timber. Recently, interest in producing multipleproducts from sal forests has increased; accordingly, a silviculturalregime for managing sal forest for multiple products is a centralconcern. Forest managers need a comprehensive scientific understandingof natural stand development processes and anthropogenic factorsaffecting sal forest when designing silvicultural regimes formultiple-product management. We review ecology and productivityplus anthropogenic niches of sal forests. Information on edaphicfactors, phenology and stand development processes (regeneration,growth characteristics, soil nutrient requirement, growth allocation,nutrient cycling, stand structure and successional stages) isimportant for designing scientific forest management of salforest; likewise, knowledge of anthropogenic factors associatedwith use of sal forest is also required for effective implementationof the recently paradigmed management efforts. Sal forest silviculturehas been evolving since the beginning of the twentieth centurymainly concentrating on timber production, though the sal forestshave always been used also for grazing and collection of fodder,fuelwood, litter and many other products. Instead of integratingthese products in sal forest management, governments have attemptedto control these additional uses through enforcing forest legislation.These attempts resulted in the persistent conflicts betweenthe interests of local people and the government, and the deterioratingcondition of sal forests. Community-based forestry in this regionemerged in response to the severe degradation of forest resources,and local people initiated protection practices and demonstratedthe success of sal forest from coppice. The coppice systemsallow managing forests with intermittent products (non-timberforest products, including fodder and litter) while producingtimber in the long term. Accordingly, a policy has been developedto manage coppice sal forest for multiple products. Managingthe sal forest for multiple products is, however, a relativelyrecent development and scientific investigations on variousaspects of multiple-product forest management need to be initiated.Ecological processes indicate good prospects of managing salforest for multiple products. The review indicates that theecological processes and anthropogenic factors form sound basisfor developing multiple-product management.  相似文献

Pine honeydew honey is an economically important non-wood forest product from eastern Mediterranean Pinus brutia forests, which are also important for timber production. Pine honey is produced by bees that feed on the honeydew secretions of Marchalina hellenica, a scale insect that infests pine stands and feeds on pine sap. The aim of this study was to optimize the joint production of pine honeydew honey and timber by maximizing the soil expectation value of pine stands. The simulation of P. brutia stand dynamics and timber production in healthy and infested stands is based on individual-tree growth and yield models that account for the effect of M. hellenica on tree- and stand-level growth and mortality. The optimization procedure uses a direct search method based on nonlinear programming. The results suggest that pine stands growing on good sites should be managed using rather short rotations and mainly aiming at timber production. In contrast, forest management in medium- and poor-quality sites should aim at longer rotations by taking advantage of the joint production of pine honey and timber assortments. Honey-oriented forest management can be much more profitable than timber production in stands growing on medium and poor sites. Pine honey represents an opportunity to increase the value and economic profitability of P. brutia forests.  相似文献

The systematic designation of protected areas is a key strategy in modern biodiversity conservation. As for now, the Natura 2000 system of the European Union (EU) is the largest coordinated network of conservation areas worldwide. Since this scheme has a focus on forests, its effectiveness substantially depends on small-scale private forest owners who represent the largest forest ownership group in Europe. We conducted a quantitative survey (n?=?1671) in Northwest Germany focusing on the perceived importance of ecosystem services, the performance of management practices, nature conservation attitudes, as well as stand characteristics of small-scale private forest owners with and without Natura 2000 sites. Forest owners perceived regulating and cultural services as more important than provisioning ecosystem services while having a multifunctional perspective on their forest. Owners with Natura 2000 sites had a stronger focus on resource use and, with the exception of habitat-tree protection, did not perform conservation measures more frequently than those without. Moreover, we found more negative nature conservation attitudes among this ownership group. In conclusion, the Natura 2000 scheme needs to be more strongly adapted to the demands of small-scale private forest owners, for example by increasing profound participation and establishing a results-based incentive scheme for conservation measures. The perspectives of small-scale private forest owners have to be considered comprehensively to ensure the effective and sustainable implementation of the Natura 2000 conservation network.

Forest management strategies, reflecting the cognition and the demands of the human population on forests, have significant effects on the forest structures and functions. Nowadays, numerous forest management strategies have been introduced and implemented worldwide for a long time. However, our knowledge about the impacts of alternative management strategies on forest multipurpose management practices is still insufficient. Therefore, the overall goal of this study quantitatively assessed the impacts of four alternative forest management strategies on forest timber and carbon values in a large forest area in northeast China, as an example. Four alternative forest management strategies: no intervention management (NIM), classical timber management (CTM), multi-purpose management (MPM), and spatial-constraints management (SCM), in conjunction with different management objectives and regulations, were quantitative assessed using optimization methods. The results of numerical analysis showed that implementing eco-friendly forest management strategies such as imposed in MPM and SCM strategies may be economic inefficiencies, mainly due to significant decreases of the joint benefits from forest timber and carbon values (approximately $18.75 and $22.36 million per year) have been observed under the current carbon trading market of China (namely $20 per ton of carbon) when the ecological- and spatial-oriented constraints were further integrated into the typical CTM strategy. However, both MPM and SCM strategies were quite meaningful for the restoration of forest resources in northeast China, in which an additional of 13.6 and 16.2 thousand tons of carbon were sequestrated during the 50 years simulated horizon. Therefore, forest decision makers should evaluate the potential effects carefully prior to altering their forest management strategy in practices.  相似文献

The contiguous forest landscapes of the Brigalow Belt Bioregion in Australia's subtropics, known as ‘the western hardwood forests’ are thought to be important for biodiversity conservation through the provision of continuous habitat features in an otherwise extensively cleared region. However, these forests have a long management history, as they are also important for timber production and stock grazing. Knowledge of the effect of these and other disturbances on the distribution and abundance of key structural or habitat features are limited and forest management activities thus continue uninformed. To address this knowledge gap, we investigated the effects of prescribed and non-prescribed disturbances on the distribution and abundance of six key habitat features (live and dead trees with hollows, large mature live trees, shrub abundance, downed coarse woody debris and litter cover) at 120 sites located in spotted gum Corymbia citriodora dominant forests within the western hardwoods.  相似文献
