Abstract:
Over the past eight decades, British Columbia's silvicultural programs have gone through three stages: initiation, establishment and development. For a long time, silviculture was a minor activity associated with timber harvesting, and the formation of silviculture as a distinct sector did not take place until the late 1960s. Shifts in societal values and changes in public expectations concerning forest management contributed to changes in B.C.'s forestry institutions that, in turn, altered the structure of silviculture programs. Especially since the 1980s, expansion in the scope and scale of silvicultural activities transformed contractual relationships. This paper profiles the contractual structure of B.C.'s silviculture sector. Results of a survey of contractors indicate that seed orchards, forest nurseries and companies holding timber tenures on public land economize on transaction costs by choosing appropriate organizational and contractual forms in accordance with identifiable attributes of silvicultural activities and firms' characteristics. Key words: silviculture, contractual forms, transaction cost, payment schemes

Abstract:
In the midst of changing social, ecological, and technical realities, interest in intensive silviculture has resurfaced. Intensive silviculture could build on previous silvicultural approaches, simply intensifying use of the treatments or treatment combinations identified in this paper to increase timber production, but the costs and benefits for specific treatments or treatment combinations remains unclear. Or intensive silviculture could be based on new thinking, refocusing so that increasing amounts of fibre are produced on dramatically younger, agricultural-like fibre farms located in areas that have the longest possible growing season. If fibre farming, using either natural or artificial regeneration, becomes increasingly more important, emphasis will start to be placed as much on equipment and integration of fibre production with manufacturer needs as on previously standard silvicultural treatments. Regardless of the form taken, some reject the suggested advantages of intensive silviculture, recommending instead a knowledge-intensive integrated approach or a combination of approaches. Although integrated landscape management is increasingly becoming the foundation for forest management, silvicultural direction remains unclear. Silviculturalists and managers will reap rewards by increasing silvicultural intensity only if their plans are scientifically based and socially acceptable. Before reasonable silvicultural directions can be developed, responsible parties need to frame and agree on the most realistic approaches that address both social and ecological concerns. Calls for increased silvicultural intensity are based on the recognition that status quo management could result in increasing fibre imports to satisfy local producer and consumer needs. Still, much of our naturally less productive northern forested land base seems far from ripe for increasing silvicultural intensity dramatically. Even so, those who continue status quo forest management solely may become increasingly less competitive. In an increasingly interdependent world market-based economy it is unclear whether intensive silviculture in northern ecosystems can be competitive with production in other parts of the world.

Abstract:
As the source of raw material for Canada's forest industry shifts from the frontier of original timber to managed crops, the policy framework influencing investments in silviculture assumes critical importance. Opportunities for economically beneficial silviculture are probably substantial, but policy makers have been provided with surprisingly little evidence of the kind they need to allocate budgets appropriately. Moreover, governments have created serious obstacles to silviculture through property tax systems that generate disincentives to forest enhancement, through forest tenure arrangements that are insecure or dampen regional timber markets, and through regulations that impede or distort silvicultural effort. Removal of these obstacles, and provision of information and guidance about silvicultural opportunities, would give considerable stimulus to improved forest management in Canada and undoubtedly at less cost than new governmental silvicultural programs. Key words: forest policy economic opportunities, incentives and obstacles for forestry, silvicultural investments, forest regulations.

Abstract:
A brief historical overview shows the mainstream development pattern in German silviculture and outlines the adjacent role of naturally-oriented silviculture. The rationale for seminatural silviculture is discussed with reference to its ecological and economical aspects. Elements of seminatural silviculture of the Baden-Württemberg-concept are introduced. This concept is not purely a preservation strategy, but recognises the importance of timber production. Some aspects of selection forests, such as the special case of uneven-aged forests with a long tradition in Southwest Germany, are mentioned. As there are still a lot of even-aged (pure) forests in Southwest Germany, transformation strategies towards uneven-aged mixed forests are shown with the aid of some examples.Criteria and indicators for seminatural silviculture which have to be developed on a regional or local scale, can be used as a basis for establishing a certification process for Southwest German forests. Seminatural silviculture is suited as a rational and integrating silvicultural system to fulfil future requirements on forests in a dynamically changing world.

Abstract:
Abstract Changing climates are altering the structural and functional components of forest ecosystems at an unprecedented rate. Simultaneously, we are seeing a diversification of public expectations on the broader sustainable use of forest resources beyond timber production. As a result, the science and art of silviculture needs to adapt to these changing realities. In this piece, we argue that silviculturists are gradually shifting from the application of empirically derived silvicultural scenarios to new sets of approaches, methods and practices, a process that calls for broadening our conception of silviculture as a scientific discipline. We propose a holistic view of silviculture revolving around three key themes: observe, anticipate and adapt. In observe, we present how recent advances in remote sensing now enable silviculturists to observe forest structural, compositional and functional attributes in near-real-time, which in turn facilitates the deployment of efficient, targeted silvicultural measures in practice that are adapted to rapidly changing constraints. In anticipate, we highlight the importance of developing state-of-the-art models designed to take into account the effects of changing environmental conditions on forest growth and dynamics. In adapt, we discuss the need to provide spatially explicit guidance for the implementation of adaptive silvicultural actions that are efficient, cost-effective and socially acceptable. We conclude by presenting key steps towards the development of new tools and practical knowledge that will ensure meeting societal demands in rapidly changing environmental conditions. We classify these actions into three main categories: re-examining existing silvicultural trials to identify key stand attributes associated with the resistance and resilience of forests to multiple stressors, developing technological workflows and infrastructures to allow for continuous forest inventory updating frameworks, and implementing bold, innovative silvicultural trials in consultation with the relevant communities where a range of adaptive silvicultural strategies are tested. In this holistic perspective, silviculture can be defined as the science of observing forest condition and anticipating its development to apply tending and regeneration treatments adapted to a multiplicity of desired outcomes in rapidly changing realities.

Abstract:
There is growing international agreement that intensive silviculture will play a major role in meeting future demand for wood and wood fibre worldwide. In Canada, however, extensive forest management continues to be the dominant paradigm. Driven by low growth rates in primary forests and the consequent long rotations, current policies support only basic management, with little or no silvicultural intervention between stand initiation and final harvests. By contrast, native conifers and hybrid poplars (Populus spp.) grown in plantations have been shown to achieve increments of 6 to 29 m3 ha-1 yr-1 in Canada. In this paper, we argue that increased production, economic, and environmental benefits can be realized in Canada by intensifying silvicultural practices over designated parts of the landbase. Indeed, the shift to intensive management may be essential to sustain Canada’s competitiveness in the international forest products sector. In reviewing past work, we demonstrate that intensive silviculture may yield outputs that are competitive with many other regions, even those in the tropics. Achieving wide support for intensive silviculture will require integration of a broader range of silvicultural, environmental, and social objectives into management planning than has traditionally been the case. Such a broad-based strategy, especially where it has gained the support of communities, may be the most balanced and effective means of resolving many of the key forest management issues that face Canada in the 21st Century.

Abstract:
Um breve histórico mostra o desenvolvimento geral da silvicultura alemã e menciona o desenvolvimento acessório da silvicultura seminatural (seminatural silviculture, naturally-oriented silviculture). As motivações, para a silvicultura seminatural são discutidas com referência a seus aspectos ecológicos e econômicos. Os elementos da silvicultura seminatural do estado de Baden-Württemberg são apresentados. O conceito em si não é uma estratégia de preservação, mas visa também à produção de madeira. Alguns aspectos de florestas jardinadas, como o bem-conhecido "Plenterwald", com sua longa tradição na Floresta Negra, são discutidos. Como ainda há muitos povoamentos puros no sudoeste da Alemanha, estratégias de conversão desses povoamentos em povoamentos mistos inequiâneos são mostrados, utilizando alguns exemplos. Critérios e indicadores de silvicultura seminatural, que são desenvolvidos por regiões ou sítios, podem ser utilizados para estabelecer um processo de certificação de madeira de florestas. A silvicultura seminatural é considerada como sistema adequado e racional para cumprir necessidades futuras das florestas num mundo que muda rapidamente.

Problem: How to mechanise tree planting in North American logged sites? Trees are presently hand planted. Preliminary exploration identified the following collection of sub-problems. Vehicle: How to carry tools reliably and cost effectively over rough obstacle strewn ground? Results: U.S.A. - patent granted European Patent Office - patent granted Canada - patent granted The patents cover the main form and mode of operation of a simple but unconventional vehicle. Silvicultural/mechanical: How to mechanise the handling and placement of trees? Results: Two International Patents allowed. They cover a magazine/feed mechanism and a placement mechanism. They form a planting tool. One man guides the vehicle/tool system. An array of planting tools is carried. Two problems arise from the need to make guidance manageable and the planting rate fast enough. Spacing: How to cause the members of a collection of simultaneously operating tools to space themselves appropriately the spacing being driven by machine perceived cues? Choice: How to cause a tool to move to and halt over a plan table spot, tool action being driven by machine perceived cues? Results: One International Patent allowed. Spacing: A conceptual solution is described. Choice: A semi-automatic solution is described. It involves a system of tool guidance and a system of tool set-up, both light guided. Two methods for the detection of light signals in the presence of sunlight have been investigated. Choice-automatic; two solutions have been explored. One uses standard data processing, the other "parallel" processing. Here an idealised device is described which will compare for likeness two two-dimensional patterns.

Abstract:
Government funding for silviculture in British Columbia has expanded recently, but remains well short of the level recommended by many foresters. This thesis contains a proposal to replace government funding with investment from capital markets. It describes the funding mechanism, analyzes the implications to government, and introduces a method of distributing investment funds through a system of competitive bidding between forest management companies. In return for their participation, investors and forest companies would both receive equity in future timber production. The thesis concludes that at a cost of foregoing 50% of its future stumpage revenue, government might replace its current spending on intensive forest management with a funding level from capital markets of $500 million to $800 million per year.

Abstract:
O meio ambiente e as interações humanas estão redesenhando a ética ambiental, a fim de torná-la mais clara e dotada de maior alcance. A ordem internacional ambiental vem merecendo espaços significativos dada a sua crescente importância na tutela dos ecossistemas do planeta. As políticas nacionais foram contempladas com novos elementos, como ocorreu com a Política Nacional do Meio Ambiente, que trouxe novas leis, instrumentos legais e diversas inovações para seu campo. Há alguns anos atrás, quando entrava no Estado uma nova atividade econômica, não havia arcabouço legal que desse guarida às questões ambientais e disponibilizasse instrumentos para a gestão do meio ambiente. Não existiam exigências legais, tampouco as preocupações globais que induzem os Estados e nações a assinar protocolos de intenção ou documentos de cooperação para satisfazer esses fins. Deste modo, esta pesquisa se propôs a estudar o instrumento do Zoneamento Ambiental da Atividade da Silvicultura elaborado para o Estado do Rio Grande do Sul, analisando esse instrumento sob uma ótica jurídico-institucional. Para isto, foi utilizada como metodologia a pesquisa qualitativa, dividindo-se esta em bibliográfica e documental e pesquisa de campo, através de entrevistas com representantes de alguns órgãos ambientais, órgão do Poder Público e algumas instituições privadas integrantes do setor florestal gaúcho. Os resultados encontrados demonstram que há dúvidas quanto à aplicação da legislação sobre o Zoneamento Ambiental e quanto à subordinação legal das instituições ambientais e sua atuação. Na percepção dos entrevistados há divergências técnicas quanto às diretrizes utilizadas para a implementação desse instrumento e ainda não há consenso, inclusive judicial, que atenda aos anseios das instituições do setor florestal gaúcho. No entanto, existe conciliação quanto a eventuais impactos gerados pela atividade e a necessidade de regrá-la, permitindo maior segurança para investimentos no setor. A ciência poderá trazer as respostas necessárias para esclarecer esse impasse ambiental.
The environment and the human interactions are redesigning the environmental ethics in order to make them clearer and gifted of a wider reach. The environmental international order has been getting significant spaces given its increasing importance under the custody of the planet ecosystem. The domestic politics were contemplated with new elements as took place with the Domestic Politics of Environment that has brought new laws, legal instruments and several innovations for its field. Some years ago when a new economic activity joined the Government there was no legal features that sheltered the environmental matters and made instruments available for the environment management. There were no legal demands, nor global concern that motivated Governments and nations to sign protocols of intentions or cooperation documents to attend this aims. Thus, this research suggested studying the instrument of Environmental Zoning of the Silviculture Activities elaborated for the State of Rio Grande do Sul, analyzing such instrument under the legal-institutional view. For such, a research qualitative methodology was adopted, one dividing it in bibliographical and documental and field survey, through interview with members of some environmental institutions, organ of Judicial Power and some private institutions members of the State of Rio Grande do Sul forestial sector. Results found demonstrate that there are doubts concerning application of legislation on Environmental Zoning and concerning its legal subordination of environmental institutions and its acting. Under the view of the interviewees there are technical divergences concerning policies taken for implementing this instrument and there is still no consensus, nor a legal one, that follows the needs of the State of Rio Grande do Sul forestial sector institutions. However, there is conciliation concerning eventual impacts caused by the activity and the need to rule it, allowing more safety for investing in the sector. Science will be able to bring the necessary answers to make this environmental dilemma clearer.

A preocupação com as questões ambientais e o desenvolvimento de diversos tipos de energias alternativas estimula a participação cada vez maior de fontes renováveis de energia. A energia gerada por meio da queima da biomassa é o maior destaque dentre as fontes renováveis, sendo uma das mais exploradas atualmente. O aumento da demanda de biomassa aumentou a necessidade de gerar uma maior quantidade de material em menor tempo e em áreas cada vez mais reduzidas. O presente estudo avaliou o crescimento e a produção da biomassa aérea em plantio de Eucalyptus grandis (Clone G21), no sistema de talhadia com enfoque na produção de biomassa florestal ao fim do ciclo de dois anos. O trabalho foi realizado na Universidade Estadual Paulista (UNESP), em área experimental da Fazenda Lageado, localizada no município de Botucatu – SP. A floresta de Eucalyptus grandis foi implantada em março de 2012 no sistema florestal de curta rotação em espaçamento de 3 x 1 m e colhida com a colhedora florestal FR 9060 da New Holland. A segunda rotação foi conduzida a partir da rebrota do plantio anterior com início em de outubro de 2013. A área foi subdivida em quatro tratamentos, os quais foram dispostos em dois fatores: com a desbrota e sem a desbrota; e com a aplicação da adubação comercial e sem a aplicação de adubação. O trabalho foi desenvolvido em um experimento inteiramente casualizado e considerou-se um esquema fatorial (2 x 2) com dois fatores, desbrota e adubação, foi realizado a ANOVA e quando apresentou diferença significativa foi realizado o teste TUKEY para a comparação entre as médias. A produção de biomassa florestal seca resultou em uma média geral dentre os tratamentos de 17,34 toneladas por hectare e o fuste foi o componente arbóreo que mais produziu tanto biomassa fresca quanto biomassa seca por hectare, o qual representa cerca de 91 % de toda a biomassa produzida na área. A densidade básica da madeira também não apresentou diferença estatística quando comparado os fatores silviculturais, obtendo uma média de 369 kg m-3. A umidade apresentou-se maior no componente fuste seguido das folhas e os galhos. Para os materiais voláteis e o teor de cinzas apenas apresentaram diferença no componente fuste, que apresentou maior média de materiais voláteis e menor média de carbono fixo. As folhas apresentaram o maior poder calorífico dentre os componentes, mas representam apenas 4,1% do total de biomassa por hectare. Nenhuma prática silvicultural comparada neste trabalho, desbrota e a adubação, apresentou um resultado com diferença significativa a 5% de probabilidade para a produção de biomassa e para a produção de energia. Desse modo, pode-se afirmar que para a talhadia de sistemas florestais de curta rotação com o enfoque para a produção de biomassa e bioenergia não faz necessário realizar as adubações e nem a desbrota, sendo que estas duas operações são onerosas, tanto economicamente como no dispêndio energético, mas para que isso ocorra devem-se atentar as boas práticas silviculturais no primeiro ciclo, principalmente para o fator adubação.
The power generated by biomass burning is the biggest highlight from renewable sources, one of the most currently used. With the increasing use of biomass, the need arises to produce more biomass in less time in a smaller area. This study aims to evaluate the growth and biomass production of Eucalyptus grandis, G21 clone, the coppice system, with a focus on production of forest biomass. The study was conducted at São Paulo State University (UNESP) in the experimental area of Lageado Farm, located in Botucatu SP. The Eucalyptus grandis forest was established in March 2012 in forest system of short rotation with spacing of 3 x 1 m at 18 months of age was held the first thinning in total area, with forest harvester FR 9060 New Holland, which gathers all the tree components, stem, branches and leaves. After harvesting the area was subdivided into 4 equal parts where set 4 treatments, which are arranged on two factors: With the completion of thinning and without the use of thinning; and the application of commercial fertilizer or without the application of commercial fertilizer. The study was conducted in a completely randomized experiment and considered a factorial arrangement (2 x 2) with two factors, thinning and fertilizing. It was found that the thinning and fertilization influenced some physical properties of forest biomass. The components of biomass differed in all the treatments. Especially the leaves which had the highest average values of the gross calorific value (20.9 MJ kg-1 ), higher fixed carbon (15 %). The highest dry matter yield, 18,690 kg, was presented by the treatment without thinning and fertilization. The same treatment also showed the highest amount of energy potential, 336.06 GJ ha-1 . Fertilization worked significantly in the production of dry biomass and consequently the energy potential per area.

Abstract:
As alterações no uso do solo decorrentes das atividades humanas modificam as condições ambientais, o que pode levar a mudanças na estrutura de comunidades locais. A expansão da silvicultura ao redor do mundo tem causado uma crescente preocupação em termos de conservação da biodiversidade. Isto por que ela resulta em uma simplificação e homogeneização do habitat originalmente nativo. Este estudo avaliou a estrutura da assembleia de aves em áreas de silvicultura e em floresta nativa, sendo que os principais objetivos foram: 1) avaliar o possível impacto da silvicultura sobre a riqueza, abundância e composição de espécies de aves, considerando diferentes idades de plantio; 2) avaliar se as espécies de aves registradas em áreas de silvicultura representam um subconjunto daquela registrada na floresta nativa; 3) analisar as respostas da diversidade funcional e dos atributos funcionais morfológicos e comportamentais das espécies de aves. Foram amostrados plantios de eucalipto de quatro idades de cultivo assim como áreas de floresta nativa num total de 150 pontos de escuta. A riqueza, a abundância de espécies de aves e a diversidade funcional foram significativamente maiores na floresta nativa. A composição de espécies também apresentou diferença significativa entre a floresta e os plantios de diferentes idades. Entretanto apesar da diferença na composição, as espécies que ocorrem nos plantios de eucalipto representam subconjuntos daquelas encontradas na floresta nativa, com um elevado índice de aninhamento para os plantios de idade mais avançada. Os resultados deste estudo indicam a ação de um filtro ambiental imposto pela silvicultura, selecionando espécies com requerimentos de habitat e atributos similares, assim como um maior número de espécies generalistas de habitat. Pode-se inferir então que áreas de silvicultura oferecem um habitat pouco complexo para a avifauna com um nível limitado de recursos e com isso, uma perda de funções ecológicas essenciais ao ambiente, como a dispersão de sementes.
Changes in land use resulting from human activities modify the environmental conditions, which can lead to changes in the structure of local communities. The expansion of silviculture around the world has caused a growing concern for biodiversity conservation. This is because it results in a simplification and homogenization of originally native habitat. This study evaluated the structure of the assembly of birds in areas of native forest and silviculture, and the main objectives were : 1) to evaluate the possible impact of silviculture on the richness, abundance and composition of bird species, with different ages of planting and 2) assess whether the bird species recorded in areas of silviculture represent a subset that recorded in native forest, 3) analyze the responses of functional diversity and functional morphological and behavioral traits of birds species. Eucalyptus plantations four ages of cultivation as well as areas of native forest in a total of 150 point counts were sampled. The richness, abundance of bird species and functional diversity were significantly higher in the native forest. The species composition also showed a significant difference between the forest and plantations of different ages. However despite the difference in composition, species that occur in eucalyptus plantations represent subsets of those found in the native forest, with a high level of nestedness for plantations older age. The results of this study indicate the action of an environmental filter arising for silviculture, selecting species with similar habitat requirements and traits, as well as a greater number of generalist species habitat. It can be inferred then that silviculture areas offer a bit complex habitat for birdlife with a limited amount of resources and thus, a loss of ecological functions essential to the environment, such as seed dispersal.

Abstract:
The Cerulean Warbler is a small migratory that is currently considered a species of special concern. Cerulean Warbler response to two types of silvicultural treatments in southern Indiana was assessed by comparing relative abundance and territory data collected during the two years prior to tree harvest to data collected one year immediately following the harvest. ArcGIS was then used to identify spatial attributes of territories that appeared to be important to the species. Lastly, a method of sampling canopy openings by using a Global Positioning System (GPS) unit was introduced. The results suggest that Cerulean Warblers were not negatively affected by the harvest and that moderate prescribed silviculture treatments that create small canopy openings can benefit the species.

Abstract:
A modificação da paisagem e a fragmentação de habitats são consideradas ameaças à biodiversidade mundial. Áreas cobertas por vegetação primária ainda preservadas e unidades de conservação são insuficientes para garantir a conservação de espécies. Cultivos de florestas homogêneas passaram a ser considerados como possíveis habitats alternativos para espécies florestais e podem contribuir para a conservação da biodiversidade. O Brasil é o país com maior área ocupada com plantio de eucalipto e essa vem crescendo nos últimos anos. Identificar quais fatores influenciam a diversidade da biota nos plantios é importante para a conservação de espécies. O objetivo do presente estudo foi conhecer a composição florística do sub-bosque de plantios de Eucalyptus saligna Sm. e avaliar se o tipo de solo e a idade do plantio influenciam a riqueza e a composiçao da vegetação que ocupa esse ambiente. Para isso foi realizado o levantamento das espécies vegetais que ocorrem nos cultivos localizados em solo argiloso e arenoso, nos quais os indivíduos de E. saligna tinham três e sete anos. Foram avaliados como fatores ambientais características do solo, produção de serapilheira pelas árvores do plantio, abertura do dossel, uso do solo no entorno do cultivo e tamanho do plantio. No total, foram encontradas 218 espécies vegetais. As análises estatísticas foram realizadas apenas com as espécies que estavam presentes em pelo menos duas unidades amostrais. Plantios em solo argiloso apresentaram maior riqueza que no solo arenoso e houve diferença significativa na composição de espécies entre os dois tipos de solo. Grande parte dos fatores ambientais mensurados também foram diferentes entre os solos. Não foi possível verificar diferenças na riqueza, na composição de espécies e nos fatores ambientais entre os plantios de diferentes idades. O tipo de solo pode ser um fator mais limitante do que a idade da floresta plantada para determinar a riqueza e composição das espécies que compõem o sub-bosque dos plantios. Embora a riqueza de espécies no solo arenoso seja menor, esse também é importante para a conservação, porque abriga espécies adaptadas à menor disponibilidade de recursos, que não ocorrem em outros ambientes. O grande número de espécies encontrado no sub-bosque destes plantios indica que eles podem auxiliar na conservação de espécies nativas, mas esse potencial deve ser melhor investigado. São recomendados estudos de outros fatores, como a biologia de espécies importantes ecológica e econômicamente, interações entre animais e plantas e diferentes estratégias de manejo, para investigar de que forma eles afetam a biodiversidade e como eles podem ajudar a avaliar e aumentar o potencial de conservação das florestas industriais.
Landscape change and habitat fragmentaiton are recognized as threats to global biodiversity.Areas with remaining primary vegetation and protected areas are insufficient to ensure species conservation. Forest monocultures are potencial alternative habitats for native species and may contribute to the conservation of biodiversity. Brazil is the country with the largest area occupied with eucalypt plantations, this area is also growing in the last years. Identifying which factors influence the biodiversity on plantations is important to species conservation. The objective of this study was to know the understory species composition in Eucalyptus saligna Sm. plantations and to evaluate the influence of soil type and stand age on species richness and species composition. Surveys of vegetation were performed in stands on clay and sandy soils where the eucalypt trees were three and seven years old. Other soil characteristics, litter production by stand trees, canopy open and land use surrounding stands were evaluated as environmental factors. 218 plant species were found in plantations understory. The stands on clay soil were richer than those on sandy soil. Most of the environmental factors evaluated were also different among stands on different soils type. It was not possible to verify differences on species richness and species composition nor environmental factors between stand ages. Soil type could be a more limiting factor than forest age to determine species richness and species composition on plantations understory. Sandy soils are poorer in species, but they are also important to conservation, since species that happen on sandy soils are adapted to low resources availability and do not occur at other locations. The large number of native species founded in eucalypts plantation understory indicates that these plantations may assist some native species conservation. Nevertheless, further research is needed to understand the conservation potential from eucalypt plantations. It is recommended other studies to be done for a better comprehension and to increase the importance of plantation forests to conservation, mainly studies about biology of key species, interactions between animals and plants and the effect of different management options.
