O conceito de Alto Valor de Conservação (AVC) foi desenvolvido pela certificação florestal FSC (Forest Stewardship Council), e tem por objetivo designar áreas com características excepcionais devido a presença de importantes atributos, divididos nas seguintes categorias: florestas com concentração significativa de biodiversidade; grandes áreas florestais em nível de paisagem, que contenham populações viáveis da grande maioria das espécies de ocorrência natural; áreas florestais contidas ou que contém ecossistemas raros, ameaçados ou em perigo; áreas florestais em situações críticas que forneçam serviços básicos da natureza; áreas florestais fundamentais para atender necessidades básicas das comunidades locais; áreas florestais críticas para a identidade cultural tradicional de comunidades locais. Trata-se de um conceito inovador ao incluir aspectos sociais e culturais, razão pela qual tem sido amplamente utilizado fora do setor florestal, sendo incorporado por esquemas de certificação ligados a commodities e biocombustíveis, empresas de cadeia de logística (produção) e instituições financeiras. A identificação dos atributos pode ser feita seguindo-se uma abordagem genérica, na qual o manejo deve contribuir para manutenção ou incremento dos atributos identificados seguindo uma abordagem de precaução, incluindo as comunidades locais no processo de identificação das áreas de AVC. Para melhor uso deste conceito em situações específicas, alguns países adaptam os conceitos gerais em documentos chamados de Interpretação Nacional. O Brasil é um dos países que ainda não possuem uma interpretação Nacional e, portanto, a identificação de áreas de AVC é feita utilizando-se a abordagem genérica. Este trabalho se propõe a uma análise ampla do uso do conceito de AVC em três diferentes escalas: análise das publicações existentes sobre o tema, aplicação regional por meio das interpretações nacionais e uso do conceito no Brasil pelos empreendimentos de manejo florestal certificado pelo FSC. O capítulo 1 consiste em uma revisão estruturada das publicações existentes a nível mundial sobre o tema, que possibilitou a formação de uma base considerando as principais informações disponíveis sobre o tema. No capítulo 2 aprofunda-se em uma análise do conceito regional, considerando apenas os países que possuem uma interpretação nacional, reconhecendo as diferenças e características próprias de cada local. Por fim, o terceiro capítulo tem como foco específico os empreendimentos de manejo florestal certificado no Brasil, possibilitando o levantamento dos atributos identificados até o momento e a realização de uma análise das etapas de condução dos estudos de AVC por meio de questionários. / The concept of High Conservation Value (AVC) was developed by the Forest Stewardship Council (FSC), and its purpose is to designate areas with exceptional characteristics due to the presence of important attributes, divided into the following categories: forests with a significant concentration of biodiversity; large landscape-level forest areas containing viable populations of the vast majority of naturally occurring species; forest areas contained or containing rare, threatened or endangered ecosystems; forest areas in critical situations that provide basic services of nature; areas that are fundamental to meeting the basic needs of local communities; areas critical for the traditional cultural identity of local communities. It is an innovative concept to include social and cultural aspects, which is why it has been widely used outside the forest sector, being incorporated by certification schemes linked to commodities and biofuels, logistics chain companies (production) and financial institutions. The identification of the attributes can be done following a generic approach, in which the management should contribute to the maintenance or increment of the attributes identified following a precautionary approach, including the local communities in the process of identifying the areas of HCV. To better use this concept in specific situations, some countries adapt the general concepts into documents called National Interpretation. Brazil is one of the countries that do not yet have a national interpretation and, therefore, the identification of areas of HCV is done using the generic approach. This work proposes a broad analysis of the use of the concept of HCV in three different scales: analysis of existing publications on the theme, regional application through national interpretations and use of the concept in Brazil by the forest management companies certified by the FSC. Chapter 1 consists of a structured review of the existing worldwide publications on the subject, which enabled the formation of a base considering the main information available on the theme. In Chapter 2, the analysis of the regional concept is analyzed, considering only the countries that have a national interpretation, recognizing the differences and characteristics of each place. Finally, the third chapter focuses specifically on certified forest management projects in Brazil, enabling the identification of attributes identified so far and conducting an analysis of the stages of conduction of HCV studies through questionnaires.

Translocation of threatened reptile species to pest-free offshore islands is one of the most important conservation management tools available in New Zealand. However, a limited knowledge of how an animal responds to translocation and what factors threaten their survival prevails. Post-translocation monitoring is crucial and may help explain the reasons for translocation failure, but only if monitoring techniques are effective in detecting animals postrelease. This thesis documents the post-release response of two small populations of Duvaucel’s geckos (Hoplodactylus duvaucelii) using radio-telemetry, translocated to Tiritiri Matangi and Motuora Islands in December 2006. The efficiency of three standard reptile monitoring techniques, including spotlight searching, artificial refuges, and footprint tracking tunnels were tested and the impact of native bird predators on island lizards was investigated. Following translocation, no mortalities were recorded and the geckos increased in body condition by 22%. Post-release activity was shown by small initial movements within the first week, followed by increasingly large-scale (up to 480 m), non-directional movements thereafter. Range areas were atypically large (up to 7,820 m²) as a result of the large-scale dispersal movements however few geckos did demonstrate small range areas. There were no sexual or island site differences in the dispersal movements or the range area estimates, suggesting that all geckos responded similarly to the translocations and release into a novel environment. Several neonate H. duvaucelii were captured on both Tiritiri Matangi and Motuora, and their high body condition scores indicated that they were capable of surviving and securing adequate resources. All three reptile monitoring techniques were capable of detecting H. duvaucelii at low densities these methods however differed significantly in their detection abilities. V Footprint tracking tunnels demonstrated the most consistent detection rates, probably due to the provision of attractive baits. Spotlight searching resulted in the recapture of 21% and 75% of founders on Tiritiri Matangi and Motuora, respectively. However, this method relied heavily on skilled fieldworkers. Artificial refuges (A.R.s) were the least effective for detecting geckos at low densities and A.R.s were only occupied by H. duvaucelii on Tiritiri Matangi Island. Environmental conditions significantly influenced the effectiveness of the monitoring methods, with temperature having a highly positive influence on tracking rates and spotlight encounters. Native birds, including kingfishers, pukekos, moreporks, and Swamp harriers are reportedly known to prey on lizards. Dietary analyses of these species revealed that lizards represented a large proportion of the prey for kingfishers on Tiritiri Matangi (88%) and Motuora (43%), and that kingfishers have the potential to seriously impact on small establishing lizard populations. Lizard remains were not present in the diet of any other bird species sampled and captive feeding experiments were inconclusive in determining if lizard remains could be detected in pukeko faeces. This research can aid in the further understanding of post-release responses of lizards to translocations and the factors that threaten their establishment. The provision of adequate habitat quality and size, release locations with a reduced number of known bird predators, and the instatement of long-term monitoring programmes will help improve the translocation success of threatened lizard species in the future.

The aim of this research is to assess various options for the management of topsoil stockpiles on disturbed lands and to evaluate the viability and germinability over time of the seedbanks in these stockpiles for use in rehabilitation. To predict their success, experimental trials were designed and conducted.

This research aims to develop the present knowledge of arid zone rehabilitation by scientifically testing topsoiling and seeding treatments on the Eyre Peninsula, South Australia, in a way that enables the widest application and comparison to other mining leases throughout the arid lands.

As rodovias podem representar um importante fator na fragmentação de habitat para espécies silvestres adaptadas a habitats de alta complexidade estrutural, como as florestas tropicais. As estradas reduzem a conectividade da paisagem e a capacidade da população regional em habitar todas as áreas adequadas e estes efeitos são mais significativos nas espécies que evitam a estrada, que são, muitas vezes, espécies de interior de florestas. A magnitude dos efeitos de barreira dependerá do comportamento e mobilidade destas espécies. Quando as estradas representam ralos (sink) ou barreiras para as populações, devido, respectivamente, aos atropelamentos ou à repulsa, medidas mitigadoras são indicadas para aumentar a conectividade entre as manchas de habitat separadas por essas estradas. A qualidade do habitat é um fator que deve ser considerado, mesmo com baixas frequências de atropelamentos nesses locais. O objetivo desse estudo foi propor dois métodos de seleção de áreas prioritárias para implantação de medidas mitigadoras dos efeitos das estradas sobre espécies de vertebrados florestais: Seleção Hierárquica Multivariada e Seleção Bivariada. A área de estudo foi o bioma Mata Atlântica, sendo recortado em paisagens hexagonais em três escalas diferentes (10.000, 1.000 e 100 km), usando a extensão Repeating Shapes no programa ArcGIS 9.3. Em cada hexágono foram calculados: área de floresta e de Unidade de Conservação, densidade de estradas e de hidrografia. Apenas os hexágonos cobertos por no mínimo 45% pela Mata Atlântica, com mais de 50% de cobertura florestal e mais de 1% de Unidades de Conservação foram incluídos nas análises. Após esta seleção, no método Seleção Hierárquica Multivariada, foi feita uma análise de componentes principais (PCA) com as quatro variáveis medidas, para cada escala separadamente. Os hexágonos foram então ordenados segundo o posicionamento deles no 1 Eixo da PCA de forma hierárquica e da maior para menor escala de hexágonos. Para área de estudo o método de Seleção Bivariada foi construído um gráfico de pontos, para cada escala de hexágono, com as variáveis cobertura florestal e rios. Foram selecionados os hexágonos que estavam localizados no quadrante do gráfico que representasse maior densidade de rios e maior porcentagem de cobertura florestal. Posteriormente foi feita uma simulação para avaliar se os métodos eram capazes de recuperar escores tão alto quanto a ordenação seguindo apenas o posicionamento dos hexágonos no Eixo 1 da PCA, sem uma análise hierárquica. O método de Seleção Hierárquica Multivariada foi mais eficiente para escolha de áreas prioritárias do que a Seleção Bivariada tanto para a escala intermediária (1.000 km) quanto para a menor escala (100 km). Os cinco hexágonos de 100 km mais prioritários estão localizados em São Paulo e Paraná, abrangendo quatro UCs (PARES de Jacupiranga, APA de Guaraqueçaba, APA Cananéia- Jacuípe e PARES da Ilha do Cardoso). Devido à simplicidade e fácil aplicabilidade do método, acredita-se que este pode ser uma opção interessante para escolha de áreas prioritárias para implantação de medidas mitigadoras dos efeitos de estradas / Roads may represent an important factor in fragmentation of habitat for wild species adapted to habitats of high structural complexity as rainforests. Roads reduce landscape connectivity and the capacity of the regional population live in all suitable areas and these effects are most significant in species that avoid the road, which are often species dependent on forests. The magnitude of the barrier effects depend on the behavior and mobility of these species. When roads represent "sinkers" or barriers for populations due, respectively, trampling or avoidance, mitigation measures are indicated to increase connectivity between habitat patches separated by these roads. The habitat quality is a factor that must be considered, even at low frequencies of road kill there. The goal of this study was to propose two methods of selecting priority areas for implementation of mitigation measures of roads effects on forest vertebrate species: Multivariate Hierarchical Selection and Bivariate Selection. The study area was the Atlantic Forest biome, being cut into hexagonal landscapes at three different scales (10,000, 1,000 and 100 km), using the extension "Repeating Shapes" program in ArcGIS 9.3. In each hexagon was calculated: area of forest, protected areas, density of roads and hydrograph. Only hexagons covered by at least 45% by the Atlantic Forest, with over 50% forest cover and more than 1% of protected areas were included in the analyzes. After this using the Multivariate Hierarchical selection method, we performed a principal component analysis (PCA) with the four variables measured for each scale separately. The hexagons were then ordered according to their position in the first axis of PCA, using a hierarchical manner and the smaller scale of hexagons. For the Bivariate selection method we did a dot plot for each scale hexagon, with the variables forest cover and rivers. We selected hexagons that were located in the quadrant of the graph that represented higher density of rivers and larger percentage of forest cover. After that, we made a simulation to evaluate if the two methods were able to retrieve scores as high as the ordination following only the positioning of the hexagons on Axis 1 of the PCA, without a hierarchical analysis. For the study site, the Multivariate Hierarchical selection was more efficient for choosing priority areas than Bivariate Selection for both the intermediate scale (1000 km) and to a lesser extent (100 km). The five hexagons of 100 km of highest priorities are located in São Paulo and Paraná, covering four protected areas (PARES of Jacupiranga, Guaraqueçaba APA, and APA Cananéia-Jacuípe and PARES Ilha do Cardoso). Due to simplicity and easy applicability of the method, we believe this may be an interesting option for selecting priority areas for implementation of mitigation measures of the effects of roads

<p>  </p> <p>The role of trust and risk tolerance has received renewed attention in the field of environmental conservation and management as scholars are increasingly interested in integrating various social, economic, political, cultural, and psychological understandings, concepts, and theories into environmental conservation and natural resource management. This dissertation has two foci. The first focus is on examining the role of trust in the development and maintenance of collaborative environmental conservation programs and factors influencing trust (Chapters 2 and 3) and the second focus is on examining drivers of risk tolerance in the context of human-wildlife conflict (Chapter 4). Specifically, Chapter 2 focuses on the development and maintenance of NGO-municipal collaborations in an incentive-based environmental conservation program in Bolivia, where an NGO coordinated with four municipal governments in the initiation and implementation of the Watershared program. With a particular focus on the role of trust, I examined how municipal and NGO staff interact to negotiate, fund, and develop Watershared, their motivations to initiate such partnerships, factors that influence the maintenance of such partnerships, and how staff within these organizations envision their future collaborations. I collected and analyzed data from 15 semi-structured interviews with municipal decision makers and conservation practitioners in the implementing NGO and data from participant observation of several Watershared events and NGO meetings, utilizing an integrated Institutional Analysis Design (IAD) framework. My results suggest that trust and interpersonal relationships built upon shared values and goals and the program history in the region were important factors shaping NGO-municipal collaborations. At the same time, my results show that the NGO and municipal partners had different visions of the future of the program, particularly who would be responsible for program funding and implementation, and different organizational capacities that may influence their abilities to maintain their collaborations over time. Together, these results demonstrate the importance of understanding local dynamics in developing and maintaining NGO-municipal collaborations, particularly the role of adaptability and interpersonal relationships and the challenges related to goal misalignments over time. In Chapter 3, I investigated trust of Watershared participants and non-participants towards various organizations and the collaborating partners of Watershared, particularly the forms of trust present and the factors influencing their trust. By collecting and analyzing data from 1,030 household surveys of Watershared participants and non-participants in 72 communities in the Department of Santa Cruz, Bolivia, my results suggest that factors influencing trust in NGOs vs municipal governments differed even as the type of trust held in both entities was the same. Specifically, that community embeddedness and program participation significantly influenced trust in NGOs while perceived fairness and equality within communities and experience of political instability influence program participants’ trust in local municipalities. Overall, these results demonstrate the utility of a multi-level trust lens in developing informed understandings of trust across organizations while highlighting opportunities for natural resource professionals to enhance trust across organizations. Finally, Chapter 4 of my dissertation moved away from research in Bolivia to examine risk tolerance and trust in a different context due to my strong interest in human-wildlife conflict. Specifically, this chapter focuses on determining the factors that drive tolerance in livestock producer-black vulture conflicts in the midwestern United States. By collecting and analyzing data from 222 surveys of livestock producer in Indiana and Kentucky, I examined the economic, psychological, and social drivers of tolerance of black vultures. The results show that economic cost (e.g., livestock loss) was not a significant factor influencing risk tolerance; rather, wildlife value orientations such as utilitarian or mutualist beliefs, previous experience with black vultures, and intangible costs (i.e., emotions associated with wildlife) were significant drivers of tolerance. This chapter highlights the importance of incorporating non-economic factors in both understanding tolerance and developing policies and programs that reduce human-wildlife conflict. Overall, my dissertation examined trust, collaboration, and risk tolerance in two distinct contexts. Together, my results demonstrate the importance of integrating understandings of trust and risk tolerance with other economic, social, and psychological theories in developing a holistic approach to promoting collaborative natural resource management to address increasingly complex environmental conservation challenges.</p> <p>  </p>
