The role of forests in nature-based tourism and recreation is becoming increasingly important. Forests, in South Africa and abroad are no longer seen simply as a source of timber, but provide spiritual and recreational services to millions of people through forest-related tourism. Consequently many countries have had to try and balance the multifunctional roles that forests play in the forestry and tourism sectors. There has been very limited research conducted to date on the role that forests and woodlands play in the tourism sector in South Africa. The study assesses the current and potential role of forests and woodlands in the tourism sector in selected regions of Finland and South Africa by means of a comparative study. The Mpumalanga and Oulu Provinces were chosen as the two case study regions. The dissertation presents a general picture of the similarities and differences between the regions and countries. The comparison of similarities and differences in the management of forest areas serves to identify different solutions to the challenges faced by the tourism sector in forest and woodland areas of Finland and South Africa. The study further measures and compares tourism providers‟ perceptions towards how they value and use forests and woodlands for tourism and recreation. How and why forests and woodlands are valued should play an important part in how they are created and managed. Management methods are then likely to be more effective and socially acceptable. In addition to examining the role of forests in the tourism sector, it is helpful to understand why people choose to visit forests and woodlands and their attitude towards forests and the environment. The study assesses why tourists visit forest and woodland areas and their attitudes towards forests and the environment. Attitudes of individuals are seen as a major factor that explains motivations for different forms of behaviour and such analysis provides useful information for organisations involved in managing forestrelated tourism. The study uses the Forest Importance Scale (FIS) and the General Awareness and Consequence Scale (GAC) as simple measures of attitudes towards forest importance and usage. Lastly the study assesses and compares the perceptions of tourists and tourism providers and the importance they place in sustainable tourism principles. Both forests and tourism are relevant issues from an environmental perspective and it is relevant for planners and managers both inside and outside the tourism industry to evaluate the level of support amongst tourists and tourism providers towards more sustainable practices. The purpose of this thesis is thus to present the findings of research conducted using a comparative approach including a comparison of two case-study regions, multiple-use Likert scales, in-depth interviews and participant observation as means for investigating the role of forests in tourism. This study reveals that forests are seen to have a significant role for tourism and play an important role in attracting tourism in many communities located near them through nature-based tourism and recreation. Forests and woodlands are especially perceived as important by tourism providers in maintaining and creating the tourism activities in the area. The results reveal that there is a need to increase and monitor local community participation in the regions as there was a high degree of uncertainty regarding involvement of the community in decision-making and tourism development in the regions. Community involvement is one of the vital components of ensuring sustainable tourism. Therefore it is important to monitor the level of community involvement in an area to ensure sustainable tourism development. The study adds a supplier and consumer perspective regarding the importance of sustainable tourism principles. The study reveals that both tourists and tourism providers in Finland and South Africa are very supportive of sustainable tourism principles in the destination. The high interest and fairly similar ranking of issues suggest that tourists and tourism providers largely share the definition of sustainability. Positive perceptions towards sustainable tourism principles will encourage tourists and tourism providers to act sustainably regarding tourism development and management. Finally the results suggest that well-managed and organized tourism in forested rural areas can play a significant role in enhancing the economic, environmental and social development in the regions. The challenge of managing sustainable forest tourism is discussed further and the results from the study aim to provide the foundation on which to formulate principles or guidelines and recommend approaches to be applied in the development and management of sustainable forest tourism in South Africa.

The Effects of Tropical Forest Management on Biodiversity and Ecosystem Functioning Eleanor M. Slade 1. Between 35 % and 50 % of all closed-canopy tropical forest has been lost, and the rate of deforestation continues to increase throughout the tropics. Despite a wealth of literature on the effects of tropical forest disturbance on the diversity and composition of a variety of taxa, there is still no clear consensus on the value of disturbed forests for biodiversity. 2. If forest management practises are to be sustainable in the long-term they should maintain both biodiversity and ecosystem functioning (the interactions and processes of the ecosystem), as well as a timber harvest. However, few studies have investigated the extent to which ecosystem functioning is reduced in logged forests. The effects of different logging intensities on a variety of taxa, and the ecosystem processes with which they are associated, were assessed in the Danum Valley Conservation Area in Sabah (Malaysian Borneo). 3. Even under high logging intensities, the forests of Sabah appear to have been managed in a way that maintains timber yields in the short-term. However, other aspects of forest structure had been affected, which could have important consequences ecologically, and for the long-term sustainability of timber harvests. 4. Combining field studies with manipulative experiments allows assessment of the impacts of species changes associated with habitat modification on measures of ecosystem functioning. Dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) functional group richness and composition were manipulated in a series of field experiments. Certain functional groups and species were found to have a greater impact on ecosystem functioning than others; nevertheless a full complement of species was needed to maintain full ecosystem functioning. 5. Dung beetles appeared to be relatively robust to changes in forest structure associated with selective logging, but species richness was reduced with high-intensity logging. There was a corresponding decrease in ecosystem functioning (dung and seed removal) with a decrease in species richness, and a decrease in the biomass of large nocturnal tunnellers, suggesting that although some species are dominant, rare species are also needed to preserve full ecosystem functioning. 6. A complex interaction between birds and ants resulted in reduced herbivory of seedlings of the important timber tree, Parashorea malaanonan, in some instances. However, this interaction was not affected by either selective or high intensity logging. Seedfall of P. malaanonan, was reduced in logged forest compared to primary forest. Despite insect seed predation being higher in primary forest, there was still successful recruitment during a non-mast year. Parasitism of insect-predated seeds was found to be inversely density dependent, and was higher in logged forest where seed predation was lower. 7. The results of this thesis suggest that the forests of Sabah appear to be being logged under a management system that is compatible with sustainable timber management, but not necessarily sustainable forest management. Low intensity selective logging seems to preserve much of the original forest structure, biodiversity and ecosystem functioning compared to logging at higher intensities. However, ecosystem processes were variable in their response to logging, suggesting that management decisions should be based on the consideration of multiple taxa and processes.

Conhecer o comportamento espacial e demográfico e a dinâmica genética das espécies madeireiras e manter uma distância entre as árvores que permita sua reprodução é essencial para o desenvolvimento de procedimentos de manejo que visem a conservação das espécies e garantia de estoques futuros de madeira. No entanto, quando uma área é explorada para fins madeireiros, as árvores remanescentes podem não ficar a uma distância viável a polinização. A legislação brasileira atual limita a exploração de espécies com baixa densidade de ocorrência e define alguns critérios para a escolha das árvores remanescentes, porém, eles levam em consideração apenas o número de indivíduos e não os fatores ecológicos e genéticos das espécies além de serem os mesmos aplicados a toda Amazônia. O objetivo deste trabalho foi analisar o comportamento espacial de três espécies madeireiras, a Manilkara huberi, a Hymenaea courbaril e o Handroanthus serratifolius, em quatro áreas de estudo na Amazônia brasileira a partir de inventários de empresas florestais e verificar a implicação das últimas mudanças ocorridas na legislação no processo de polinização dessas espécies. O trabalho foi dividido em duas partes. A primeira verificou se essas três espécies possuem o mesmo padrão espacial em diferentes regiões da Amazônia e discutiu a questão da raridade presente na legislação. Foi calculada a densidade e a matriz do vizinho mais próximo para todos os indivíduos antes do corte das três espécies em cada área de estudo e as distâncias plotadas em um gráfico quantil-quantil. Os resultados mostraram que a Manilkara huberi é uma espécie que pode ser encontrada em alta ou baixa densidade e em agregados ou não dependendo da região de ocorrência, diferente do Handroanthus serratifolius que apresenta uma densidade e padrão de distribuição semelhante independente da região de ocorrência. A Hymenaea courbaril permeia entre essas duas situações. Notou-se uma semelhança na distribuição das espécies entre as áreas próximas. A segunda parte analisou as consequências da alteração da legislação na distância entre as árvores remanescentes das três espécies e verificou se essa distância era viável para o processo de polinização. Foi simulado o corte a partir de cenários legislativos, em que apenas o diâmetro mínimo de corte (DMC) foi alterado. Os resultados mostraram que houve uma diminuição na distância entre árvores. A diminuição favoreceu o processo de polinização visto que os polinizadores precisam percorrer menores distâncias na busca por alimento. A legislação tem tomado um caminho mais conservativo, porém há muito o que ser desenvolvido, visto que cada espécie possui sua própria ecologia reprodutiva mas são manejadas da mesma forma. / The information about the spatial and demographic behavior and the genetic dynamic of timber species and maintaining a distance between trees that allows their reproduction is essential for the development of management procedures to conserve species and guarantee future wood stocks. However, when an area is harvested for timber purposes, the remaining trees may not stay at a feasible distance for pollination. Current Brazilian legislation limits the exploitation of low-density species and defines some criteria for choosing the remaining trees. However, they take into account only the number of individuals and not the ecology and genetic aspects of the species. Besides, the same criteria are applied to the entire Amazon. The aim of this study was to analyze the spatial behavior of three timber species, Manilkara huberi, Hymenaea courbaril and Handroanthus serratifolius, in four study areas in the Brazilian Amazon Forest. Companies inventories were used to verify the implication of the latest changes in the Brazilian legislation on the pollination process of these species. The study was divided into two parts. The first one verified if these three species have the same spatial pattern in different regions of the Amazon and discussed the rarity issue in the legislation. The density and the nearest neighbor distance matrix were calculated for all individuals before cutting for the three species in each study area and the distances were plotted on a quantile-quantile plot. The results showed that Manilkara huberi can be found in high or low density and aggregated or not depending on the region of occurrence. On the other hand, other than Handroanthus serratifolius populations present similar densities and distribution patterns despite region of occurrence. Hymenaea courbaril permeates between these two situations. The distribution of this species among nearby areas showed similarity. The second part of this work analyzed the consequences of changes in Brazilian forest management legislation on the distance between the remaining trees of the three species and verified whether this distance was feasible for the pollination process. The cutting was simulated based on two legislative scenarios, in which only the minimum cut diameter (MCD) was changed. The results showed that there was a decrease in the distance between trees due to the increase of the density of remaining individuals. The distance decrease favored the pollination process, since pollinators need to travel shorter distances searching for food. Brazilian forest legislation has taken a more conservative path, but there is still much to be developed, since each species has its own reproductive ecology, even so are managed the same way.

A crescente preocupação mundial com o manejo dos recursos florestais tem exercido grande pressão nos ambientes extrativistas e industriais ligados à base produtiva silvícola. Em vista da dificuldade de se estabelecer quais empresas e produtores adotam padrões produtivos ambientalmente sustentáveis, o uso das certificações tem ganhado notoriedade, funcionando como mecanismo de sinalização de comportamento mercadologicamente valorizado. Este cenário representa empiricamente teorizações da Economia da Informação em um ambiente agroindustrial específico, apresentando ferramentas de emissão de sinais como potenciais redutores da assimetria de informação presente na estrutura econômica de comércio. Contudo, permanecem questionamentos sobre como este uso de certificações e conseqüente melhoria da disponibilidade informacional podem impactar sobre as firmas adotantes desta estratégia. Relacionando esta situação com elementos da Economia Industrial (abordagem Estrutura-Conduta-Desempenho) e caracterizando a sinalização como um elemento de Conduta, esta pesquisa se propõe a verificar empiricamente potenciais impactos desta estratégia de atuação no Desempenho resultante. Como objeto específico de estudo, elegeu-se, dentro da indústria silvícola brasileira, o setor de papel e celulose, dada a sua relevância econômica para o agronegócio brasileiro. O método de análise de desenvolve através de modelos econométricos que buscam estabelecer e mensurar relações de influência entre a evolução de adoção de certificações de manejo florestal sustentável no desempenho exportador agregado do setor para o período 1995- 2008 (dados mensais), visto que a prática de comércio internacional potencializa a disponibilidade assimétrica de informações. Os resultados encontrados são parcialmente conclusivos em direção à sustentação da hipótese de que o uso de certificações tem influências positivas sobre o desempenho de comércio exterior da indústria brasileira de papel e celulose. / World’s increasing concern regarding forest resources management has pressured the producers and industries connected to forestry activities. In face of the difficulty to differentiate agents’ productive patterns of behavior towards forests, the use of sustainable forest management certifications is becoming increasingly relevant, working as a supposedly market valued signaling device. This scenario represents empirically in a specific agroindustrial environment the theories developed in Information Economics, presenting signal emission tools as potential reducers of commercial information asymmetry. However, questions regarding how the use of these certifications and the consequent improvement of information availability impact on firms which adopt this strategy remain. Relating this situation with the elements of Industrial Economics (more specifically the Structure-Conduct-Performance approach) and defining the signaling behavior as a Conduct pattern, this research proposes an analysis of the possible impacts of this strategy in the resulting Performance. As object of study, the Brazilian Pulp & Paper (P&P) industry is chosen, given its economic importance for the country’s forest and agribusiness sectors. The methodology to develop this verification is based on econometric regression models, aiming to establish and measures influences between the sustainable forest management certifications implementation evolution in the aggregated exporting performance of the Brazilian P&P industry for the period 1995-2008 (monthly data), since the international trade is expected to rise the levels of information asymmetry and hence the value of signals. Results allow partial acceptance of the hypothesis that the use of certifications has positive influences on Brazilian P&P industry’s international trade performance.

The object of study was state forest resources of Mažeikiai state forest enterprise. Purpose of study - define, if the forest management of Mažeikiai forest enterprice compile with the requirements of sustainable forest management. It was used data comparison method, according to the system of criteria and indicators, accepted in Ministerial conference, in 1998, Lisbon.For the evaluation of indicators and criteria, dataof forest inventories of 1982, 1998 were used. It was also used data for comparison, obtained from State forest survey service for the year of 2004. The results of analysis showed that restitution process of land has interrupted the continuous run of sustainable forest management, but the conditions of forest are improving. The decline of forest sanitary state was caused by abiotic factors and followed by insect invasion, which reduced resistance of forests. As a negative factor, the increase of spruce stands is determined. It will reduce stand resistance more and it is not favourable for conservation of biodiversity.

The Sustainable Forest Management (SFM) was first introduced in all commercial forest reserves in Sabah in 1997. This policy gives hope to the state government to manage the forests in a sustainable manner following the forest development phase of revenue oriented timber exploitation, which has contributed to the decline in forest resources; the increase in forest degradation and the decrease in state income earned from the forestry sector. Under the SFM concept, the forest of the state was divided into Forest Management Units (FMUs) managed by FMU holders under different institutional arrangements of state, state enterprise and private sector. This study was conducted to investigate the corporate-stakeholder interrelation under the SFM concept implemented by the FMU holder in Sabah, Malaysia. The research was based on the ‘Triple Typology Perspective of Stakeholder Theory’, which encapsulates three different perspectives of ‘conceptual’, ‘corporate’ and ‘stakeholder’ centric. The ‘conceptual’ perspective explores the overall SFM concept and its relation to the FMU holder – stakeholder interaction. The ‘corporate’ view investigates how the FMU holders as the corporate part of the SFM concept deals with their stakeholders; and the ‘stakeholder’ perspective analyses the relation between stakeholders, the FMU holders and SFM implementation. Stakeholder analysis was used to gather information with the application of methods incorporating literature reviews, expert interviews, focus groups, meetings and discussion, questionnaire surveys and Q methodology. Four FMUs were selected as study areas, which managed by the state, state enterprise and private sector. The respondents were encompassed personal of Sabah Forestry Department (SFD), FMU managers and FMU workers, various governmental and non-governmental agencies, and local communities of eight villages located within and in the fringe of FMU areas involved in the study. Under the ‘conceptual centric’, different groups of stakeholders were identified based on SFM documentation, which also provide the normative basis for the SFM concept. The contemporary implementation of SFM was assessed based on stakeholders’ perspective, which indicated that the overall SFM contribution entailed mainly on satisfaction of environment objectives, followed by economic and, to a lesser degree, social objectives. Different categories of stakeholders were identified based on their perceptions of various issues under SFM implementation. These include the level of cooperation or conflict; degree of stakeholder participation; views of specific individuals and a thorough comparison of individual subjectivity. There is, however, an agreement to the statements on the influential factors towards effective SFM implementation, which include the administration and leadership of SFD, and good collaboration between SFD and the FMU holders. Other consensuses were related to the roles of participation in promoting learning about synergy and the importance of various forest uses, and that it should be able to influence the decision-making during the consultation process. The implementation of SFM was agreed in influencing towards investment in the forestry sector and the development of the rural area in the state. The ‘corporate centric’ indicates the different approaches of stakeholder management under the different arrangements of FMU holders. The SFM operations with a high level of stakeholder involvement were identified as community forestry programme followed by forest conservation, forest protection, development and preparation of plans, administration, human resource development, and research and development. The important stakeholders, according to their degree of involvement in SFM operations were the internal stakeholders of FMU workers, followed by external stakeholders of the staff of SFD, contractors, local communities, local authorities, consultants, businessmen/traders and researchers/scientists. Other stakeholders were various state government agencies, manufacturers, shareholders, NGOs (local), international agencies, NGOs (international), donors, federal government agencies and other FMU holders. The ‘stakeholder centric’ identifies the various stakeholders interests and claims associated with SFM implementation that depend on stakeholder affiliation. The main groups in this study were multi-interest stakeholder groups (n=104) and the local community groups of the selected villages (n=332). The interests and claims of the multi-interest stakeholder group were related to SFM objectives such as good management of the forest, protection and conservation of environment and biodiversity, and protection of water catchment areas. The local community groups, on the other hand, were mainly concerned with the importance of the forest as a source for foods, land for agriculture and other livelihood purposes. There are various approaches for stakeholder relation management (SRM) that are employed by the FMU holders and stakeholders. These may consist of management quality system, CSR program, the community forest development project; inter agency meetings and dialogue; and collaboration and cooperation with other agencies and institutions. SRM can assist in balancing conflicts that arise, promoting cooperation, and advancing the knowledge and understanding on the SFM concept among the stakeholders. The SRM approaches under the SFM implementation can augment participation by the stakeholders, which in turn will promote effective and efficient implementation of SFM. The mutual relation of the SFM concept and SRM is advancing stakeholder participation in promoting effective implementation of SFM at the FMU level. The inter-relation of the ‘triple perspective typology of stakeholder theory’ was integrated as new contexts to achieve objectives for sustainability under SFM policy, with the business case of corporate sustainability, and the wider scope of the ecosystem approach and the sustainable development. / Das Konzept Sustainable Forest Management (SFM) wurde erstmals in allen kommerziellen Waldreservaten in Sabah, Malaysia, im Jahr 1997 eingeführt. Mit dieser Politik verbindet die Landesregierung die Hoffnung, dass die Wälder nun in einer nachhaltigen Art und Weise bewirtschaftet werden können, nachdem die fast ausschließlich auf Einnahmen orientierte Holznutzung zum Rückgang der Waldbestände, zur Zunahme der Waldzerstörung und damit letztendlich auch zum Rückgang der Staatseinnahmen aus der Forstwirtschaft beigetragen hat. Zur Umsetzung des SFM-Konzepts wurde der Staatswald in Forest Management Units (FMU) unterteilt, die von FMU Haltern aus verschiedenen Staatsinstitutionen, Staatsunternehmen und der Privatwirtschaft verwaltet werden. Die vorliegende Arbeit untersucht das Verhältnis zwischen Unternehmen als FMU-Bewirtschaftern und Stakeholdern im Konzept nachhaltiger Waldbewirtschaftung, das von FMUs in Sabah, Malaysia implementiert wurde. Die Arbeit basiert auf der „Triple-Typology Perspective of Stakeholder Theory“, welche drei verschiedene Perspektiven beinhaltet, die konzeptionell, unternehmensbezogen oder Stakeholder-zentriert sind. Dabei untersucht die konzeptionelle Perspektive SFM-Konzepte und die daraus resultierenden Beziehungen zwischen FMU-Bewirtschafter und ihren jeweiligen Stakeholdern. Die unternehmenszentrierte Sicht legt den Schwerpunkt darauf, wie FMU-Bewirtschafter als Teil des SFM-Konzeptes mit Stakeholdern interagieren. Die Stakeholder-Perspektive analysiert das Verhältnis zwischen Stakeholdern, FMU-Bewirtschafter und der SFM-Implementierung. Die Daten wurden mit Hilfe der Stakeholder-Theorie unter Anwendung quantitativer und qualitativer Methoden wie Literaturrecherche, Experteninterviews, Fokusgruppen, informellen Treffen und Diskussionsrunden, schriftlichen Befragungen und der Q-Methodologie erhoben. Als Untersuchungseinheiten wurden vier FMUs ausgewählt, die durch den Staat, den staatlichen Forstbetrieb und den privatem Sektor bewirtschaftet werden. Die Befragungsteilnehmer setzten sich aus Personal der Forstverwaltung Sabah (Sabah Forestry Department, SFD), den FMU-Bewirtschaftern und –Mitarbeitern, verschiedenen Regierungs- und Nicht-Regierungsorganisationen und lokalen Gemeinschaften in acht Dörfern innerhalb sowie im Randgebiet der FMUs zusammen. In Bezug auf die konzeptionelle Perspektive wurden, basierend auf der SFM-Dokumentation, verschiedene Stakeholder-Gruppen identifiziert, die die normative Basis für das SFM-Konzept liefern. Dessen Implementation wurde aus Sicht der Stakeholder analysiert. Es zeigte sich, dass der gesamte Beitrag zum SFM vornehmlich umweltbezogene Zielsetzungen erfüllt, gefolgt von ökonomischen und, zu einem noch geringeren Grad, sozialen Zielen. Mehrere Kategorien von Stakeholdern wurden auf Grundlage ihrer Wahrnehmung verschiedener Aspekte im Zuge der SFM-Implementation identifiziert. Diese umfassen die Kooperations- oder Konfliktebene, den Grad der Stakeholder-Beteiligung sowie individuelle Betrachtungen. Es gibt eine Übereinstimmung zu Äußerungen, welche Einflussfaktoren hinsichtlich effektiver SFM-Implementierung entscheidend sind. Dabei wurden vor allem das Management und die Führung der, der SFD sowie gute Zusammenarbeit zwischen dem SFD und den FMU-Bewirtschaftern genannt. Weitere Übereinstimmung besteht darin, die Weiterbildung über die Bedeutung unterschiedlicher Waldnutzungen und deren Ausbalancierung zu stärken, um die Entscheidungsfindung im Konsultationsprozess beeinflussen zu können. Auch herrschte Einigkeit darin, durch Investition in den Forstsektor und Entwicklung ländlicher Regionen die Implementation von SFM zu stärken. Der unternehmensbezogene Fokus konzentriert sich auf die verschiedenen Ansätze des Stakeholder-Managements unter unterschiedlichen Charakteristika der FMU-Bewirtschafter. SFM-Maßnahmen mit einem hohen Grad an Stakeholder-Beteiligung sind Gemeinschaftsforstprogramme (community forestry programmes), gefolgt von Waldnaturschutz, Waldschutz, Entwicklung und Vorbereitung von Plänen, Verwaltung, die Entwicklung von Humanressourcen sowie Forschung und Entwicklung. Die wichtigsten Stakeholder, bezogen auf ihren Beteiligungsgrad in SFM-Maßnahmen, waren intern die Mitarbeiter der FMUs und extern die Mitarbeiter der SFD, Vertragsnehmer, lokale Gemeinschaftsgruppen und Verwaltungen, Berater, Geschäftsleute/Händler und Forscher/Wissenschaftler. Weitere Stakeholder waren verschiedene Regierungsorganisationen, Produzenten, Aktionäre, internationale Behörden, lokale und internationale NGOs, Behörden der föderalen Regierung und andere FMU-Bewirtschafter. Die Stakeholder Perspektive identifiziert verschiedene Interessen und Forderungen der Stakeholder, die sich auf die SFM-Implementation beziehen und von der Stakeholder-Zugehörigkeit abhängen. Die Hauptgruppen in dieser Studie waren sogenannte Mehrinteressen-Stakeholder-Gruppen (n=104) und lokale Gemeinschaftsgruppen (n=332). Die Interessen und Forderungen der Mehrinteressen-Stakeholder-Gruppen waren bezogen auf SFM-Ziele wie gute Waldbewirtschaftung, Schutz und Erhaltung der Umwelt und Biodiversität sowie Schutz von Wassereinzugsgebieten. Andererseits stand der Wald als Quelle für Nahrung, landwirtschaftliche Flächen und andere Aspekte des Lebensunterhaltes im Mittelpunkt des Interesses lokaler Gemeinschaftsgruppen. Es gibt zahlreiche Ansätze für das Management von Stakeholder-Beziehungen (Stakeholder Relation Management, SRM), welches durch FMU-Bewirtschafter und Stakeholder genutzt wird. Der SRM-Ansatz besteht aus dem Bewirtschaftungsqualitätssystem, CSR-Programm, dem Gemeinschaftswaldentwicklungsprojekt, multilateralen Treffen und Dialog zwischen den Behörden, und Zusammenarbeit und Kooperation mit anderen Behörden und Organisationen. SRM kann dazu dienen, mögliche Konflikte auszubalancieren, Kooperation zu begünstigen sowie das Wissen und Verständnis von SFM zu fördern. Die Einbindung von SRM in die Implementation von SFM erweitert die Beteiligung der Stakeholder, was wiederum zu einer effektiveren und effizienteren Implementation von SFM auf FMU-Ebene führen kann. Die Wechselbeziehungen zwischen der „Triple-Perspective Typology of Stakeholder Theory“ und dem Ökosystemansatz, der unternehmensbezogenen Nachhaltigkeit und dem Konzept des Sustainable Forest Management bilden die Grundlage, um das Ziel einer umfassenden Nachhaltigkeit zu erreichen.

Novas tecnologias, como o LiDAR, t?m permitido a constru??o de mapas e obten??o de estimativas que auxiliam tanto no planejamento quanto nas etapas de explora??o e monitoramento do impacto. Com o intuito de reunir os diversos produtos do escaneamento laser aerotransportado (ALS) dispersos na literatura e ?teis no manejo florestal, o objetivo deste trabalho foi apresentar uma sequ?ncia metodol?gica para determinar e monitorar as restri??es ambientais e operacionais em uma ?rea sob manejo na Amaz?nia. A ?rea de estudo encontra-se na fazenda Cauaxi, munic?pio de Paragominas, estado do Par?. Foram sobrevoados 1214 hectares de Floresta Amaz?nica submetidas a manejo de impacto reduzido. Foram gerados os modelos digitais de terreno (MDT), hidrol?gicos e topogr?ficos. A vegeta??o foi mapeada por meio dos modelos de densidade relativa (MDR), de biomassa, de localiza??o de ?rvores dominantes e codominantes, de clareiras e gerado o mapa da infraestrutura existente. Por fim, a estrutura vertical da floresta foi analisada pela descri??o do perfil vertical do dossel. A resolu??o do MDT foi de 1 metro e foi poss?vel observar a varia??o da eleva??o local e os divisores de ?gua. A densidade de drenagem foi de 1,7 km/km? e as ?reas de preserva??o permanente (APP) de cursos d??gua e nascentes somaram 137,7 ha.

A declividade variou de 0 a 30?, n?o apresentando APP por declividade, caracter?stica de um relevo predominantemente suave ondulado. As ?reas com restri??o ao trator skidder n?o ultrapassaram 1 km? e, as restritas aos caminh?es carregados somaram 1,9 km?. A densidade de estradas na ?rea foi de 23,42 m.ha-1 e o n?mero de p?tios por hectare foi de 0,04. A ?rea total impactada pela abertura de estradas, trilhas e p?tios foi de 30,77 hectares, correspondendo ? 2,54% da ?rea total. Foi poss?vel observar menores valores de biomassa nas unidades de produ??o anual j? exploradas. O mesmo ocorreu entre os valores de porcentagem de clareiras. O valor de biomassa m?dio, considerando pixels de 50 m?, foi de 35,5 kg. Os menores valores dos par?metros de forma e escala da fun??o Weibull para o sub-bosque mostraram rela??o com as ?reas impactadas pela abertura de infraestrutura, sendo uma alternativa ao MDR no monitoramento do impacto. J? o par?metro de escala para o estrato da copa teve rela??o com o modelo de m?ximo dossel, indicando a localiza??o das ?rvores emergentes.

New technologies, such as LiDAR, have made possible to obtain maps and estimates which help on the planning, exploitation and impact monitoring phases. In order to gather the useful products of airborne laser scanning (ALS) in forest management, the objective of this work was to present a methodological sequence to determine and monitor the environmental and operational constraints in an area under management in the Amazon. The overflown area is located at the Cauaxi farm, municipality of Paragominas, state of Par?, Brazil. The ALS covered 1214 hectares of amazon forest submitted to reduced impact logging. Then, models such as digital terrain model (DTM), hydrological and topographic were extracted. Furthermore, the vegetation was mapped through models of relative density (MDR), biomass, localization of dominant and codominant trees, and clearing and map of the existing infrastructure. Finally, the forest vertical structure was analyzed by the description of the canopy height profile. The 1meter resolution DTM allowed to observe the variation of elevation and water dividers. The drainage density was 1.7 km/km? and the permanent preservation areas (PPA) related to water courses and springs comprised 137.7 ha. Underused maps such as micro-basins and vertical and horizontal distances could be considered in the division of the area into annual production units and in the PPA delimitation, respectively. The slope ranged from 0 to 30 ? and did not present PPA by slope, characteristic of a predominantly soft wavy relief. The areas restricted to the skidder tractor does not exceed 1 km?, and those restricted to loaded trucks generated a total of 1.9 km?. The density of roads inside the area was 23.42 m.ha-1 and the number of the storage yards per hectare was 0.04. The area impacted by the opening of roads, trails and yards was 30.77 hectares, corresponding to 2.54% of the total area. It was possible to observe lower values of biomass in the annual production units already exploited. The same occurred with the percentage values of clearings. The average biomass value considering pixels of 50 m? was 35.5 kg. The lower values of shape and scale parameters of the Weibull function for the understory were related to the areas impacted by the infrastructure opening. The maps obtained with the Weibull parameters for understory can be an alternative to the RDM on the impact monitoring. The canopy scale parameter was related to the tall canopy model, indicating the location of the emergent ones. It was possible to accurately map the areas with environmental and operational restrictions from the ALS, as well as obtaining other interesting products for forest management. This work presents a methodological guide for the insertion of ALS in the planning of all stages of forest management.

A crescente preocupação mundial com o manejo dos recursos florestais tem exercido grande pressão nos ambientes extrativistas e industriais ligados à base produtiva silvícola. Em vista da dificuldade de se estabelecer quais empresas e produtores adotam padrões produtivos ambientalmente sustentáveis, o uso das certificações tem ganhado notoriedade, funcionando como mecanismo de sinalização de comportamento mercadologicamente valorizado. Este cenário representa empiricamente teorizações da Economia da Informação em um ambiente agroindustrial específico, apresentando ferramentas de emissão de sinais como potenciais redutores da assimetria de informação presente na estrutura econômica de comércio. Contudo, permanecem questionamentos sobre como este uso de certificações e conseqüente melhoria da disponibilidade informacional podem impactar sobre as firmas adotantes desta estratégia. Relacionando esta situação com elementos da Economia Industrial (abordagem Estrutura-Conduta-Desempenho) e caracterizando a sinalização como um elemento de Conduta, esta pesquisa se propõe a verificar empiricamente potenciais impactos desta estratégia de atuação no Desempenho resultante. Como objeto específico de estudo, elegeu-se, dentro da indústria silvícola brasileira, o setor de papel e celulose, dada a sua relevância econômica para o agronegócio brasileiro. O método de análise de desenvolve através de modelos econométricos que buscam estabelecer e mensurar relações de influência entre a evolução de adoção de certificações de manejo florestal sustentável no desempenho exportador agregado do setor para o período 1995- 2008 (dados mensais), visto que a prática de comércio internacional potencializa a disponibilidade assimétrica de informações. Os resultados encontrados são parcialmente conclusivos em direção à sustentação da hipótese de que o uso de certificações tem influências positivas sobre o desempenho de comércio exterior da indústria brasileira de papel e celulose. / World’s increasing concern regarding forest resources management has pressured the producers and industries connected to forestry activities. In face of the difficulty to differentiate agents’ productive patterns of behavior towards forests, the use of sustainable forest management certifications is becoming increasingly relevant, working as a supposedly market valued signaling device. This scenario represents empirically in a specific agroindustrial environment the theories developed in Information Economics, presenting signal emission tools as potential reducers of commercial information asymmetry. However, questions regarding how the use of these certifications and the consequent improvement of information availability impact on firms which adopt this strategy remain. Relating this situation with the elements of Industrial Economics (more specifically the Structure-Conduct-Performance approach) and defining the signaling behavior as a Conduct pattern, this research proposes an analysis of the possible impacts of this strategy in the resulting Performance. As object of study, the Brazilian Pulp & Paper (P&P) industry is chosen, given its economic importance for the country’s forest and agribusiness sectors. The methodology to develop this verification is based on econometric regression models, aiming to establish and measures influences between the sustainable forest management certifications implementation evolution in the aggregated exporting performance of the Brazilian P&P industry for the period 1995-2008 (monthly data), since the international trade is expected to rise the levels of information asymmetry and hence the value of signals. Results allow partial acceptance of the hypothesis that the use of certifications has positive influences on Brazilian P&P industry’s international trade performance.

Conhecer o comportamento espacial e demográfico e a dinâmica genética das espécies madeireiras e manter uma distância entre as árvores que permita sua reprodução é essencial para o desenvolvimento de procedimentos de manejo que visem a conservação das espécies e garantia de estoques futuros de madeira. No entanto, quando uma área é explorada para fins madeireiros, as árvores remanescentes podem não ficar a uma distância viável a polinização. A legislação brasileira atual limita a exploração de espécies com baixa densidade de ocorrência e define alguns critérios para a escolha das árvores remanescentes, porém, eles levam em consideração apenas o número de indivíduos e não os fatores ecológicos e genéticos das espécies além de serem os mesmos aplicados a toda Amazônia. O objetivo deste trabalho foi analisar o comportamento espacial de três espécies madeireiras, a Manilkara huberi, a Hymenaea courbaril e o Handroanthus serratifolius, em quatro áreas de estudo na Amazônia brasileira a partir de inventários de empresas florestais e verificar a implicação das últimas mudanças ocorridas na legislação no processo de polinização dessas espécies. O trabalho foi dividido em duas partes. A primeira verificou se essas três espécies possuem o mesmo padrão espacial em diferentes regiões da Amazônia e discutiu a questão da raridade presente na legislação. Foi calculada a densidade e a matriz do vizinho mais próximo para todos os indivíduos antes do corte das três espécies em cada área de estudo e as distâncias plotadas em um gráfico quantil-quantil. Os resultados mostraram que a Manilkara huberi é uma espécie que pode ser encontrada em alta ou baixa densidade e em agregados ou não dependendo da região de ocorrência, diferente do Handroanthus serratifolius que apresenta uma densidade e padrão de distribuição semelhante independente da região de ocorrência. A Hymenaea courbaril permeia entre essas duas situações. Notou-se uma semelhança na distribuição das espécies entre as áreas próximas. A segunda parte analisou as consequências da alteração da legislação na distância entre as árvores remanescentes das três espécies e verificou se essa distância era viável para o processo de polinização. Foi simulado o corte a partir de cenários legislativos, em que apenas o diâmetro mínimo de corte (DMC) foi alterado. Os resultados mostraram que houve uma diminuição na distância entre árvores. A diminuição favoreceu o processo de polinização visto que os polinizadores precisam percorrer menores distâncias na busca por alimento. A legislação tem tomado um caminho mais conservativo, porém há muito o que ser desenvolvido, visto que cada espécie possui sua própria ecologia reprodutiva mas são manejadas da mesma forma. / The information about the spatial and demographic behavior and the genetic dynamic of timber species and maintaining a distance between trees that allows their reproduction is essential for the development of management procedures to conserve species and guarantee future wood stocks. However, when an area is harvested for timber purposes, the remaining trees may not stay at a feasible distance for pollination. Current Brazilian legislation limits the exploitation of low-density species and defines some criteria for choosing the remaining trees. However, they take into account only the number of individuals and not the ecology and genetic aspects of the species. Besides, the same criteria are applied to the entire Amazon. The aim of this study was to analyze the spatial behavior of three timber species, Manilkara huberi, Hymenaea courbaril and Handroanthus serratifolius, in four study areas in the Brazilian Amazon Forest. Companies inventories were used to verify the implication of the latest changes in the Brazilian legislation on the pollination process of these species. The study was divided into two parts. The first one verified if these three species have the same spatial pattern in different regions of the Amazon and discussed the rarity issue in the legislation. The density and the nearest neighbor distance matrix were calculated for all individuals before cutting for the three species in each study area and the distances were plotted on a quantile-quantile plot. The results showed that Manilkara huberi can be found in high or low density and aggregated or not depending on the region of occurrence. On the other hand, other than Handroanthus serratifolius populations present similar densities and distribution patterns despite region of occurrence. Hymenaea courbaril permeates between these two situations. The distribution of this species among nearby areas showed similarity. The second part of this work analyzed the consequences of changes in Brazilian forest management legislation on the distance between the remaining trees of the three species and verified whether this distance was feasible for the pollination process. The cutting was simulated based on two legislative scenarios, in which only the minimum cut diameter (MCD) was changed. The results showed that there was a decrease in the distance between trees due to the increase of the density of remaining individuals. The distance decrease favored the pollination process, since pollinators need to travel shorter distances searching for food. Brazilian forest legislation has taken a more conservative path, but there is still much to be developed, since each species has its own reproductive ecology, even so are managed the same way.
