Over 200 conservation biologists, ecologists, managers, landowners and private citizens from 14 countries met to explore the themes that networks of people are our conservation force and networks of other organisms are our conservation resource. Ninety-four oral and 25 poster papers were presented at the conference. The major conclusions were that there was a need for greater trust between professional and government agencies, scientists, community groups, landowners and individuals and a greater involvement of indigenous peoples in tackling nature conservation problems.

There is increasing public policy interest in the management of rural landscapes for conservation, both in terms of natural and cultural heritage. Agri-environmental policies are an important part of an emerging vision for a sustainable countryside, with increasing support for the existing Environmentally Sensitive Area (ESA) and Countryside Stewardship (CS) schemes. This paper provides insight into the nature of land-manager attitudes towards the conservation of rural landscapes and how these relate to differing modes and levels of engagement with these two schemes. It is based on the results of a recently completed project exploring the attitudes and practices of 100 land managers towards features of landscape and historic interest. Agri-environmental research has often sought to ‘typologise’ attitudes and practices around discrete land-manager types; an approach that may downgrade commonalities between land managers, the potential interplay of elements defining these types, and the possibility that land-manager identities may not be uniform. In this paper, in contrast, we emphasise the significance of these three analytical issues surrounding land-manager attitudes and practices. We explore land managers' interest and investment in conservation and go on to explain how these concerns were often closely related to the wildlife, historic and aesthetic goals of the schemes. The analysis then considers in detail how a concern for conservation often came to interplay with economic concerns to produce different attitudes and practices. We term these ‘styles of participation and nonparticipation’ to emphasise that such modes of uptake are not necessarily associated with specific land-manager types. Land managers developed these attitudes and practices with respect to different parts of their farms, types of landscape feature, and scheme in question. We conclude by emphasising the importance of contextualised analyses of land-manager values, knowledges, and practices for exploring the nature and possibilities of a ‘sustainable countryside', and the role of agri-environmental policy within this policy vision of rural areas.

THIS issue marks the completion of 20 years of publication of Pacific Conservation Biology. Writing in the first issue, Foundation Editor Craig Moritz highlighted the ‘profound and urgent problems in conservation and land management’ in the Pacific region, as well as ‘the inadequate communication among research biologists, conservation managers and administrators.’ He saw PCB as promoting this badly needed communication regarding conservation issues in the region, as well as highlighting the ‘relevance and management implications of the research.’ He invited researchers and managers to ‘enjoy it, use it and be part of it!’

The introduction of alien species to New Zealand's terrestrial ecosystems has caused rapid loss of native biodiversity since human settlement. Faced with this crisis, conservation managers and scientists have responded by developing innovative techniques such as translocation of native animals and the eradication of introduced mammals from islands. We review recent progress with conservation of New Zealand's terrestrial flora and fauna (especially birds) and consider future prospects for ecological restoration of islands and mainland areas. We stress the value of linking species and ecosystem approaches to conservation and we reinforce the importance of maintaining a dynamic partnership between researchers and conservation managers in the development of conservation initiatives.

Relationships between protected area managers and adjacent communities, as well as communities’ attitudes, views and perceptions of these areas, are critical for the success of conservation efforts. It is important for protected area managers and administrators to understand how local communities view these areas and their management, so that they can build sustainable working rel ationships. This paper is based on a survey of 375 semi-structured questionnaires administered to household heads, living at distances ranging from the edge of the reserves to 50 km away from the reserve boundary across the Great Fish River, Mkambati, Hluleka, and Tsolwana nature reserves in the Eastern Cape Province, South Africa. The paper provides a longitudinal assessment of households’ knowledge about the role of reserves and the reserves’ impacts on livelihood assets. In addition to households’ knowledge about the role of reserves, the paper also provides an assessment of people’s attitudes towards their location and management, as well as views on the best way to manage the reserves. For 79% of community members, reserves were important as they were seen to conserve biodiversity and valuable ecological systems necessary for sustaining life. Most (75%) respondents indicated that closely located reserves gave them opportunities to learn about nature conservation and to subsidize their incomes through tourism ventures. However, 58% had a problem with reserves’ staff, due to restrictions on resource use, which negatively impacted their livelihoods. Over half (51%) of the households argued that sustainable conservation can only be achieved through an integrated approach where conservation and local communities’ needs are given equal weight. We concluded that reserve managers should look at communities as active partners in the management of protected areas if sustainable conservation objectives are to be realised.

SummaryNational park management has the dual mission of protecting and conserving natural systems and providing services to visitors. These two goals are often contradictory, especially when levels of recreation and tourism increase. We studied whether and how the management of the 13 terrestrial national parks in Germany respond to increasing numbers of visitors. One to three managers from each national park completed an online questionnaire and were then interviewed by phone. We found no general strategy for managing high levels of recreational use. Adaptation to increasing visitor numbers seemed to be complex and arduous. Management options are particularly constrained by the mandatory public participation process, in which various stakeholders are involved in decision-making. Given the political pressure to make amends for restrictions imposed by designated protected areas, national park management is characterized by compromises, which results in a shift of priorities from conservation towards service provision. We argue that to maintain the balance between the dual objectives of conservation and recreation, park managers need the support of both social and biological research communities. Above all, the unique ecological merits of national parks could be more strongly highlighted to increase the general public’s acceptance of park restrictions.

Ecological theory provides applications to biodiversity management—but often falls short of expectations. One possibility is that heuristic theories of a young science are too immature. Logistic growth predicts a carrying capacity, but fisheries managed with the Lotka-Volterra paradigm continue to collapse. A second issue is that general predictions may not be useful. The theory of island biogeography predicts species richness but does not predict community composition. A third possibility is that the theory itself may not have much to do with nature, or that empirical parameterization is too difficult to know. The metapopulation paradigm is relevant to conservation, but metapopulations might not be common in nature. For instance, empirical parameterization within the metapopulation paradigm is usually infeasible. A challenge is to determine why ecology fails to match needs of managers sometimes but helps at other. Managers may expect too much of paradigmatic blueprints, while ecologists believe them too much. Those who implement biodiversity conservation plans need simple, pragmatic guidelines based on science. Is this possible? What is possible? An eclectic review of theory and practice demonstrate the power and weaknesses of the ideas that guide conservation and attempt to identify reasons for prevailing disappointment.

Cape Town is a unique city. It has a global biodiversity hotspot, in the midst of an urban area. Historically, nature conservation practice excluded and marginalized certain groups of people based on their race and class. This has led to peoples&lsquo
disconnection from nature. Rapid biodiversity loss is a major concern for conservators. In the last three decades, there has been a paradigm shift in conservation practice in certain parts of the world. The Cape Flats Nature programme based in Cape Town followed suit and aimed to stimulate a bottom-up participatory approach to conservation and replace the traditional top-down management strategy. The programme was tasked to reconcile the challenges of complex and conflicting relationships between urban poverty, unequal access to resources and biodiversity conservation. This study was aimed at investigating the relationships between conservation management, community partners and urban conservation areas. These relationships are vital for the progression of new conservation practice in places where people live and work. In addition, the transformative aspects of conservation in relation to social inclusion and the shift in conservation approaches was investigated. The study was conducted at five of Cape Town&lsquo
s nature reserves, Edith Stephens Wetland Park, Macassar Dunes, Harmony Flats, Wolfgat and Witzands Aquifer Nature Reserves. Data collection included in depth interviews with key informants from various conservation organizations, the Cape Flats Nature Programme team, the managers of the selected reserves and community partners. Others included observational methods and analysis of secondary data. It was found that relationships between conservators and local communities are not easily created and maintained but relationships regardless of its depth are equally beneficial to communities and the conservators. Balancing social needs with conservation needs is a struggle for conservators but many successes came in cases where this balance was realized. In addition, the transformation of conservators&lsquo
identity has changed community perceptions of conservation practice holistically. Although, many informants feel that transformation continues to remain unequal.

The objective of the study was to determine how visitors perceive park management method alternatives to preserve scenic beauty in Mounds State Park, and how other factors, such asvisitor characteristics and primary purpose for visiting the state park affected their preferences. Additionally, this study has presented a comparison of preferences for park management approaches between park managers and visitors, and a relationship between visitors' perceptions of scenic beauty and other factors. Furthermore, this study explored the contribution of a qualitative analysis. The result showed that visitor preferences for some park management approaches were influenced by sociodemographic characteristics, while visitor preferences for other park management approaches were influenced by the current state of scenic conditions in the park. Differences were observed between park manager's perceptions and visitors' perceptions. Visitors' perceptions of scenic beauty were related to whether or not they had visited the park in the past. Finally, it was clear that qualitative analysis was worthwhile for obtaining information that quantitative data could not provide.

Annotation:

Den 11 mars 2020 klassificerade Världshälsoorganisationen (WHO) covid-19 viruset som en pandemi. I Sverige infördes restriktioner för att begränsa smittspridningen av viruset genom att minska människans fysiska kontakt. Under pandemin började allt fler människor besöka naturområden och besöksantalet ökade kraftigt. Syftet med studien var att undersöka förhållandet mellan människa och natur i relation till stödjande- och kulturella ekosystemtjänster som människan tillgår när hon vistas i naturen. Studiens metod utgjordes av en kvalitativ intervjustudie som bestod av två delar för att inkludera flera perspektiv. Den första intervjumetoden begränsades till fyra naturområden belägna i Skåne och en naturvårdsförvaltare från vardera område samt en vaktmästare från ett av områdena intervjuades. Den andra intervjumetoden inkluderade fem individer som vistats i skånska naturområden under pandemin. Studiens resultat visade att besöksantalet ökat markant i tre av fyra naturområden och störningen från mänsklig aktivitet har varit kraftig i vissa områden. Effekten på hur stödjande ekosystemtjänster påverkats till följd av störningar gick inte att fastställa då det inte gått tillräckligt lång tid sedan besökstrycket ökade till följd av pandemin. Människan har kunnat nyttja naturområden för avslappning, återhämtning och sociala aktiviteter och därmed har kulturella ekosystemtjänster haft en större betydelse för människan under pandemin. Studiens slutsats är att vidare forskning behövs för att undersöka vilka långtgående konsekvenser som covid-19 pandemin haft på människans och naturens mående eftersom kunskap inom området saknas.
The World Health Organization (WHO) declared the covid-19 virus a pandemic on the 11th of March 2020. Sweden introduced restrictions to limit the spread of the virus and to restrict people's physical contact with each other. During the pandemic people started to visit natural areas and the number of visitors in these places increased. The purpose of the study was to examine the relation between human and nature and the affiliation with the supportive- and cultural ecosystem services that people utilize when they spend time in nature. A qualitative interview method was chosen to fulfill the purpose of the study. We interviewed four nature conservation managers in four different natural areas in Skåne county, a caretaker in one of the areas, and five individuals who had visited natural areas during the pandemic. The result of the study displayed that the number of visitors had significantly increased in three out of four natural areas and the disturbance from human activity was potent in some of the areas. It was not possible to determine how human disturbance affected the supportive ecosystem services since not enough time had elapsed since the increase of visitors. People have used the natural areas to relax, be restored, and to engage in social activities. The cultural ecosystem services have thus been of greater importance for people during the pandemic. The study also concluded that more research is needed to examine the long-term effects of the pandemic on human’s and nature's wellbeing.

Interest in renewable energy and governmental mandates has motivated land managers to consider cellulosic feedstocks for bioenergy. I investigated plant community response to a system including switchgrass ( Panicum virgatum) as a feedstock intercropped with loblolly pine (Pinus taeda). I estimated plant species evenness, richness, and diversity and biomass production, with emphasis on white-tailed deer ( Odocoileus virginianus) forages. I detected 225 species in 2,220 1-m² quadrats, and 7,495 biomass samples (96.4 kg dry weight) from 960 quadrats. Intercropping reduced plant species diversity, total non-pine tree biomass, and biomass of deer forages during switchgrass establishment. These effects were no longer apparent at treatment level two years after switchgrass establishment, except that deer browse and total deer forage biomass remained less in intercropped interbeds. Intercropping in managed pines may temporarily effect plant communities but further studies are needed to examine longer term effects and to quantify effects on nutritional carrying capacity for deer.

The Eden To Addo Corridor Initiative aims to connect formally protected areas in a conservation corridor from the coastal area of the Eden District near Plettenberg Bay, Western Cape, South Africa to the Addo National Elephant Park, Eastern Cape, South Africa. The corridor will incorporate government and privately owned land, and will be an attempt to maintain ecological processes at a range of spatial and temporal scales. The Langkloof Valley lies between the Baviaanskloof World Heritage Area and the Tstitsikamma National Park; two formally protected areas that will be incorporated into the Eden To Addo Corridor. Spatial prioritization analyses allow conservation planners to select areas that should be targeted for conservation action based on a range of criteria. Historically, ecological criteria have been included mostly alone in spatial prioritization. Recently, the idea of ‘conservation opportunity’ has emerged in the field of conservation planning; the notion suggests that a range of different types of data should be included in processes to spatially prioritise for conservation. By including those data defined as ‘human’ and ‘social’ data into prioritising activities, the feasibility of conservation plans can be accounted for, but historically conservation planners have failed to do so. I conducted a literature review that demonstrated that although the importance of human and social data are acknowledged in the conservation planning literature, these data that define opportunity are rarely actually included in spatial prioritisation analyses. I then carried out a social assessment that allowed me to define the social and human context of our study area and, specifically, what stewardship instruments land managers in the Langkloof would be prepared to engage. We found that land managers were generally willing to engage, but lacked the financial capacity to adopt conservation methods. Using a subset of the social and human data that were collected in the social assessment, I trialled a new Decision Support Software to fuse those data with ecological data in a novel attempt to identify priority areas for conservation action based on ecological integrity and feasibility. We also scheduled (ranked) land managers to approach for conservation action with a focus on local champions and clusters of land managers displaying strong conservation characteristics. Two corridors were identified; a major corridor in the western region of the valley and a secondary corridor closer to the middle. The members of the Initiative have been briefed on the outcomes, which provided them an opportunity to provide feedback; it is hoped that the framework of this study can be used for planning future connections. The Eden To Addo Corridor Initiative sent out a stewardship extension officer in February 2011 to approach those land managers areas that were identified. This planning exercise is a good demonstration of how, by collaborating effectively, academic conservation planners can contribute to supporting decision making by organizations that are implementing conservation action.

Annotation:

We are currently faced with the global challenge of conserving biological diversity while also increasing food production to meet the demands of a growing human population. Land-use change, primarily resulting from conversion to production land, is currently the leading cause of biodiversity loss. This occurs through habitat loss, fragmentation of remaining natural habitats, and resulting edge effects. Land-sparing and land-sharing approaches have been discussed as alternative ways to engineer landscapes to mitigate biodiversity loss while meeting production objectives. However, these represent extremes on a continuum of real-world landscapes, and it will be important to understand the mechanisms by which adjacent land use affects natural remnant ecosystems in order to make local land-management decisions that achieve conservation, as well as production, objectives. This thesis investigates the impact of juxtaposing production and natural forest on the community-wide interactions between lepidopteran herbivores and their parasitoids, as mediated by parasitoid spillover between habitats. The first and overarching objective was to determine whether herbivore productivity drives asymmetrical spillover of predators and parasitoids, primarily from managed to natural habitats, and whether this spillover alters trophic interactions in the recipient habitat. The study of trophic interactions at a community level requires understanding of both direct and indirect interactions. However, community-level indirect interactions are generally difficult to predict and measure, and these have therefore remained understudied. Apparent competition is an indirect interaction mechanism thought to be very important in structuring host-parasitoid assemblages. However, this is known primarily from studies of single species pairs, and its community-wide impacts are less clear. Therefore, my second objective was to determine whether apparent competition could be predicted for all species pairs within an herbivore assemblage, based on a measure of parasitoid overlap. My third objective was to determine whether certain host or parasitoid species traits can predict the involvement of those species in apparent competition. My key findings were that there is a net spillover of generalist predators and parasitoids from plantation to native forest, and that for generalists, this depends on herbivore abundance in the plantation forest. Herbivore populations across the edge were linked by shared parasitoids in apparent competition. Consequently, an experimental reduction of herbivore density in the plantation forest changed parasitism rates in the natural forest, as predicted based on parasitoid overlap. Finally, several host and parasitoid traits were identified that can predict the degree to which host or parasitoid species will be involved in apparent competition, a finding which may have extensive application in biological control, as well as in predicting spillover edge effects. Overall, this work suggests that asymmetrical spillover between production and natural habitats occurs in relation to productivity differences, with greater movement of predators and parasitoids in the managed-to-natural forest direction. The degree to which this affected species interactions has implications for landscape design to achieve conservation objectives in production landscapes.

AbstractUrban green infrastructure could represent an important mean for environmental mitigation, if designed according to the principles of restoration ecology. Moreover, if suitably executed, managed and sized, they may be assimilated to meta-populations of natural habitats, deserving to be included in the biodiversity monitoring networks. In this chapter, we combined automatised and expert opinion-based procedures in order to select the vascular plant assemblages to populate different microhabitats (differing in terms of light and moisture) co-occurring on an existing green roof in Zurich (Switzerland). Our results lead to identify three main plant species groups, which prove to be the most suitable for the target roof. These guilds belong to mesoxeric perennial grasslands (Festuco-Brometea), nitrophilous ephemeral communities (Stellarietea mediae) and drought-tolerant pioneer species linked to nutrient-poor soils (Koelerio-Corynephoretea). Some ruderal and stress-tolerant species referred to the class Artemisietea vulgaris appear to fit well with local roof characteristics, too. Inspired by plant sociology, this method also considers conservation issues, analysing whether the plants selected through our procedure were characteristic of habitats of conservation interest according to Swiss and European laws and directives. Selecting plant species with different life cycles and life traits may lead to higher plant species richness, which in turn may improve the functional complexity and the ecosystem services provided by green roofs and green infrastructure in general.

Since the colonial era, the region has experienced two different key strategies of landscape appropriation: (1) diversification of activities in the landscape; and (2) specialisation focusing on a few landscape products. These two strategies fall at opposite ends of a modified continuum over time, including a range of intermediate situations that combine elements of the diversified and specialised strategies. The first strategy is characteristic of Afro-descendant communities, based on harmony with nature and favoring human well-being, while providing multiple ecosystem services and cultural or spiritual values.In this context, this chapter reviews the relationship of Afro-descendants with their environment in the Colombian Pacific region, taking as an example the San Marcos locality. Through interviews with key informants and participant observation, we investigate the productive and extractive practices in San Marcos. Results show that the appropriation strategy combines different sources of income. This denotes a great local ecological knowledge geared to maintenance of biodiversity. Despite Law 70 (1993) stipulating Afro-descendant communities to have guaranteed autonomy and the right to collectively manage their ancestral lands, this socio-ecological production landscape is endangered due to pressures from the dominant society towards conversion to a specialised strategy. Finally, we also analyse “transformative change” in the context of governance of San Marcos. Such change could guide a profound transformation in conservation strategies based on a fundamental reorientation of human values.

Why ancient woodlands and wood species restoration and rehabilitation is necessary? In Turkey there are over 500 taxa of trees and shrubs, however only a few of them play a vital role both naturally and culturally. The technical term here is ‘intergenerational equity’, or in plainer language, not messing things up for our children and grandchildren. In ancient woodland restoration and rehabilitation approach in Turkey, there is no lack of knowledge to implement suitable strategies, however what is more often lacking is an understanding of the overall landscape and the factors that determine whether different land-uses are mutually reinforcing or in conflict. These applications need to accommodate new perspectives and ideas to put ancient woods back into the natural and cultural landscapes. The experience gained indicates that such implementations require supportive local and national policy frameworks and a strong constituency of local-level support. As a country with already significant areas of a highly degraded nature, but also containing diverse natural and cultural landscapes, Turkey should apply suitable techniques to bring these ancient woods back into their original landscapes in order to sustain its cultural and natural heritage. Ascertaining, and then maintaining, the condition of ancient woodland in Turkey like in UK will be a major challenge for the future. Turkey contains ancient cultural landscapes with distinctive ancient wood and ancient woodlands. They are strongly influenced by human activity reaching back far into history. This is very obvious in Anatolia, a region where eastern and western civilizations meet. The region has also been recognized by eastern and western civilizations nearly as a ‘tree paradise’ with its diverse tree species adapted to different climatic and geomorphological conditions. In this context, it has been aimed to; (1) emphasize the interaction between cultural features and diverse forest landscapes with ancient woodlands, (2) introduce the understanding of ancient woodland concept in Turkey, (3) determine the typical prominent ancient woodland taxa, (4) represent some techniques in order to restore degraded ancient woodland ecosystems in Turkey and (5) seek opportunities for the planning of undisturbed ancient landscapes as a cultural heritage. Additionally, the importance of developing strategies in order to prevent the loss of ancient woodlands was tried to be illustrated by two case studies on Common yew (Taxus baccata L.) and Common boxwood (Buxus sempervirens L.), which have been continuosly present in Anatolia since thousands of years, became an important component of cultural landscapes, however strongly influenced by human activity resulting with the degardation and loss of their habitats.

This chapter studies the difficulties encountered by the various operators trying to keep track of the changes a typical product goes through. The customized nature of the services offered by General Bank and the right of the clients to revise their products along the way creates a puzzle for an organization needing to be collectively reactive to these changes. From the perspective of the back office, capital guarantee products (CGPs) are disruptive: they impose themselves on a bank's conservation methods and demand new rules. The challenge for the bank comes from its complex topography, as contacts with the outside world morph from being driven by the front office (salespeople, traders, engineers) to being the realm of the back-office managers.

Abstract.—This paper presents a synopsis of discussions by commercial and subsistence fishers, biologists, fishery managers, and academicians about salmon management held at the symposium (this volume). The group reviewed current strategies and discussed changes that may be made to improve management with respect to fish numbers, stakeholder needs, and engagement of local people. The conservation of salmon Oncorhynchus spp. was a shared value among all participants along with the belief that sustainable salmon yields will ensure sustainable rural communities within the Arctic-Yukon-Kuskokwim (AYK) region. Management by escapement goals was a useful management strategy; however, substantial concerns were expressed that high risks to salmon populations and fisheries existed when goals were based on maximum sustained yield concepts. Weekly in-season teleconferences among fishery participants and managers have provided important information, improved decision making, and built relationships and trust between managers and fishers. Traditional ecological knowledge was viewed as an important source of information and could be further incorporated into management decisions. Studies should be conducted to understand the nature of selective fishing on salmon (e.g., size, life history, sex), and its effects on the long-term sustainability of salmon populations. Allocation of subsistence harvest in times of salmon scarcity should recognize and prioritize human food as the highest use, then dog food, and last customary trade uses. Opportunities should be explored to increase interaction between freshwater and ocean managers to achieve a more holistic, ecosystem-based management of salmon stocks over their entire life history. Tensions exist within the fisheries including: commercial versus recreational versus subsistence fishers; downstream versus upstream fishers; and state versus federal management of subsistence fisheries. These tensions will continue to pose a challenge to management. With improved information, communication, and cooperation, successful management of AYK salmon is possible and will help ensure sustainability and opportunity for use by future human generations.

Abstract.— Scientists, managers and fishers have always known that uncertainty is an integral part of nature. Early assessment models dealt with uncertainty as a signal-noise problem, developing deterministic, equilibrium relationships to explain cause and effect. Other models coped with uncertainty by normalizing model outputs against inputs that were known to be highly variable (for example, yield per recruit analysis, which avoids consideration of recruitment variability by performing calculations on a per recruit basis). Although deterministic approaches are still widely used, it is also true that methods for quantifying and presenting uncertainty have been taught, developed, and applied for several decades. The question has been less one of how to present uncertainty, rather than whether to present it. What purpose would it serve? Experience showed that managers or politicians presented with a range of estimates frequently chose to set quotas from the risk-prone end of the range. In short, uncertainty was used as a reason for avoiding conservation measures. Development of the precautionary approach to fisheries management has initiated a transition in the perception of uncertainty from that of a reason to avoid action to that of a reason to exercise caution. Increased public awareness of the limits to the productivity of natural marine resources and increasing numbers of economically devastating stock collapses have been instrumental in initiating the transition, more so than scientific advances in the modeling and representation of uncertainty. This transition is, however, more active on paper than in actual implementation. Today, one challenge is to integrate science and management into a rigorous, risk-averse, decision analysis framework, and another is to further promote responsible management and the application of the precautionary approach in the face of uncertainty. Presentation of uncertainty as risk profiles or Bayesian posterior distributions rather than confidence intervals around point estimates has provided a more objective basis for evaluating the consequences of alternative management decisions, but there is a need for better comprehension of the full consequences of the large risks managers, fishers and other stakeholders (which includes the public in general) often appear to be willing to take.

Considerations on the conservation of an etruscan archaeological landscape: the case of Cerveteri fortificationsWhere now stands the city of Cerveteri (RM), between the ninth and third century BC took form one of the most important city-states of Etruria: Caere. Today this place is especially noted for the presence of the Etruscan necropolis of Banditaccia, inserted in the UNESCO World Heritage List in 2004. The remains of the ancient fortifications, that represent one of the most interesting and well-preserved examples of an Etruscan defensive wall, are instead less known. Due to a prolonged abandonment and a presence of uncontrolled vegetation, the conservation of this testimony is now compromised by visible signs of deterioration. At the same time, this condition has defined a suggestive archaeological landscape in which architecture and nature coexist in a precarious balance. This contribution tries to deepen the importance of preserving this evocative symbiosis and proposes a possible conservative approach that could manage the relationship between ruins and vegetation.

Faced with natural habitat degradation, fragmentation, and destruction, it is a major challenge for environmental managers to implement sustainable land use policies promoting socioeconomic development and natural habitat conservation in a balanced way. Relying on artificial intelligence and operational research, reserve selection and design models can be of assistance. This paper introduces a partitioning approach based on Constraint Programming (CP) for the reserve selection and design problem, dealing with both coverage and complex spatial constraints. Moreover, it introduces the first CP formulation of the buffer zone constraint, which can be reused to compose more complex spatial constraints. This approach has been evaluated in a real-world dataset addressing the problem of forest fragmentation in New Caledonia, a biodiversity hotspot where managers are gaining interest in integrating these methods into their decisional processes. Through several scenarios, it showed expressiveness, flexibility, and ability to quickly find solutions to complex questions.

According to the definition of the International Union for Conservation of Nature and Natural Resources (IUCN), wetlands on Earth are areas that are flooded or saturated with water, artificial or natural, permanently or temporarily flooded with standing, sitting or running water. These areas include areas where water is the predominant element, such as swamps, wetlands, peatlands, estuaries, sea branches and lagoons, lakes, rivers and artificial reservoirs with a depth of more than six meters. Considering the importance of these territories and with the deep conviction that the preservation of their flora and fauna can be ensured by combining long-term national policy with coordinated international action, the scientific community reacted to the encroachments and unreasonable attitude to them by concluding 02.02. 1971 of the Convention on wetlands of international importance, especially as waterfowl habitats, known to the general public as the Ramsar Convention. The main objectives of this document are to manage wetlands as sites of great economic, cultural, scientific and conservation value, to avoid damage and loss and to preserve them through prudent use, i.e. through their continuous development. The object of study in the present work is the biological diversity, in particular the avifauna of some of the internationally important wetlands in the border areas between Bulgaria, Greece, the Republic of North Macedonia and Albania in view of the opportunities they offer for the development of some forms of alternative types of tourism.

Geologic hazards pose a significant threat to pipeline integrity. As an existing pipeline system ages, targeted analysis and positioning of maintenance resources become increasingly important to remediating problem pipeline sections and to ensure timely response to system failures. A geographic information system (GIS) now is commonly used to model pipeline systems. Significant geologic hazards can be mapped and effectively managed in a GIS database as a way to assess risk and to target pipeline remediation resources. In particular, the potential for soil corrosion is a significant threat to pipelines. In the U.S., digital soil maps from the United States Department of Agriculture, Natural Resources Conservation Service (USDA NRCS) have been compiled into the Soil Survey Geographic (SSURGO) database. Numerous soil attributes are stored in the database allowing for a detailed examination of soil characteristics. SSURGO data is largely consistent in quality and geographic extent across the U.S. and is the best available database for a national assessment of soil corrosion potential. We describe the development of a national database for the collection of locations of known corrosion from pipeline system managers. This database can be compared to soil conditions, as noted in SSURGO or other supporting soil data, for the development of a model of soil parameters that may indicate the future potential for buried pipeline corrosion. This paper outlines the need for such a database, significant design considerations and the proposed process for model development.

Currently, there is a rapid growth of demand for cultural tourism and there is a growing trend of cultural interest as a tourism product in the world. Indonesia has a lot of cultural and historical heritage with a multicultural population and serves as an integral part of the world's cultural heritage. In order to have an impact on the economy, this cultural heritage must be managed properly. Therefore there needs to be a study on the cultural heritage tourism model by balancing the interests between the tourism industry and heritage preservation as the main agenda to get a mutually sustainable relationship in cultural heritage tourism. The objectives in research are to; 1) knowing the potential of the Maghilewa traditional village as a cultural tourism destination, 2) knowing the feasibility of the traditional village as a cultural heritage destination, 3) formulating the steps that will be taken to prepare the traditional village as a cultural heritage destination. This research is a qualitative descriptive study to get an overview of the potential and feasibility of cultural tourism villages and the steps to make traditional villages into cultural tourism destinations. The results showed that the traditional village of Maghilewa was feasible to be developed into a cultural heritage destination. In developing the traditional village of Maghilewa, it is feasible as a cultural heritage destination, it requires a lot of support from the community, local government, and academics. The steps that must be taken are to build synergy between stakeholders in order to build the capacity of the Maghilewa Traditional Village community and encourage the Regional Government to implement comprehensive policies in participatory tourism development by prioritizing the conservation of local culture.

Current regulations for prediction and management of potential delayed failures from existing pipeline dents rely primarily on depth and conservative assumptions related to threat interactions, which have shown limited correlation with industry failures. Such miscorrelation can lead to challenges in managing effectiveness and efficiency of pipeline integrity programs. Leading integrity techniques that entail detailed assessment of complex dent features rely on the use of finite element analysis, which tends to be inefficient for managing large pipeline systems due to prohibitively complex modeling and analysis procedures. While efforts are underway to improve dent assessment models across the industry, these often require significant detailed information that might not be available to operators; moreover, they suffer scattered model error which makes them susceptible to unclear levels of conservatism (or non-conservatism). Nevertheless, most techniques/models are deterministic in nature and neglect the effect of both aleatory and epistemic uncertainties. Operators typically utilize conservative assumptions based on subject matter experts’ opinions when planning mitigation programs in order to account for different types of uncertainties associated with the problem. This leads to inefficient dig programs (associated with significant costs) while potentially leaving dents on the pipeline which cannot be quantitatively risk assessed using current approaches. To address these concerns, the problem calls for a dent assessment framework that balances accuracy with the ability to assess dent and threat integration features at a system-wide level with available information in a practical timeframe that aligns with other integrity programs. This paper expands upon the authors’ previously published work regarding a fully quantitative reliability-based methodology for the assessment of dents interacting with stress risers. The proposed semi-quantitative reliability model leverages a strain-based limit state for plain dents (including uncertainty) with semi-quantitative factors used to account for complex geometry, stress riser interactions, and operating conditions. These factors are calibrated to reliability results from more detailed analysis and/or field findings in order to provide a simple, conservative, analytical-based ranking tool which can be used to identify features that may require more detailed assessment prior to mitigation. Initial validation results are provided alongside areas for continued development. The proposed model provides sufficient flexibility to allow it to be tailored/calibrated to reflect specific operator’s experience. The model allows for a consistent analysis of all types of dent features in a pipeline system in a short period of time to support prioritization of features while providing a base-level likelihood assessment to support calculation of risk. This novel development supports a dent management framework which includes multiple levels of analysis, using both deterministic and probabilistic techniques, to manage the threat of dents associated with stress risers across a pipeline system.

Der volle Inhalt der Quelle

Annotation:

Operational pressure cycle fatigue (PCF) is one of the integrity threats managed by pipeline operators. Usually, hazardous liquid pipeline operators are most interested in the effects of pressure cycles since these pipelines inherently experience more significant pressure cycles than natural gas pipelines. The parameters considered in the assessment of operational pressure cycles include pipe geometry (diameter and wall thickness), mechanical properties of the pipe, distribution of hypothetical defect sizes that may exist in the pipeline, and pressure cycles. In performing these assessments, the most conservative value for each parameter is commonly used for predicting a time to failure. As such, the results are inherently overly conservative. A statistical assessment method, PCFStat, has been developed to more appropriately model the input parameters used in the assessment of operational pressure cycle fatigue; especially for cases where the deterministic approach identifies relatively short remaining fatigue lives. A distribution of each of the input parameters is developed, and then a Monte Carlo simulation of these parameters is performed. The results produced by this analysis are then used to evaluate the probability of a failure (leak or rupture) for a defined time interval.

Over time, forest education has had to adapt to keep up with global changes and to accomodate the needs of students and society. While facing pressing global issues like climate change, deforestation, illegal logging and food security, the role of higher forest education has shifted away from traditional teaching approaches and practices to methods that emphasize sustainable development, community-based management and environmental conservation in forestry. In doing so, forest education has cultivated human expertise that understands the complexity of ever-changing environments, masters state of the art technologies to manage fores and natural resources, and is capable of creating, communicating and implementing related policies in global communities and societies. In this context, educational technology and online lerning enable flexible, accessible, effective, and high-quality forest education. A case study of a Sustainable Forest Management Online program led by the Faculty of Forestry, University of British Columbia (UBC) shows that appropriately integrating educational technologies into an interntionally developed and recognized high quality curriculum is an effective way to create accessible and affordable forest education in meeting the demand of evolving societal and environmental conditions.Keywords: forest education; educational technology; international collaboration, open educational resources

The North American plains bison once numbered in the tens of millions, but only around 1,000 individuals remained by the late 1800s. Through the actions of private individuals and organizations, the establishment of a few protected, federally managed, herds saved the subspecies from extinction and today the Department of the Interior (DOI) supports ap-proximately 11,000 plains bison in 19 herds across 12 states. DOI chartered the Bison Conservation Initiative in 2008, which established a framework for bison conservation and restoration on appropriate lands within the species’ histori-cal range. With the recent announcement of the 2020 DOI Bison Conservation Initiative, DOI outlined a diverse range of accomplishments made under the 2008 Initiative and re-affirmed the commitment to work with partners in support of managing bison as native wildlife. Both the 2008 and 2020 DOI Bison Conservation Initiatives endorse a holistic approach, addressing health and genetic considerations, and recommend managing DOI bison herds together as a metapopulation to conserve genetic diversity by restoring gene flow. Bison conservation and restoration efforts must consider the significance of disease in bison herds and apply a multi-jurisdictional, multi-stakeholder approach to the management of bison on large landscapes. Robust herd health surveillance programs, both in the donor and recipient herds, along with strong partnerships and communication, are needed to protect the century-long success of DOI bison conservation and stewardship. This report discusses overarching principles affecting bison health decisions in DOI herds and provides detailed baseline herd health history and management, providing a foundation upon which the 2020 Bison Conservation Initiative vision for DOI bison stewardship can be realized.

Increased climate variability, including more frequent and intense drought, is projected for the southwestern region of the United States. Increased temperatures and reduced precipitation lower soil water availability, resulting in decreased plant productivity and altered species composition, which may affect forage quality and quantity. Reduced forage quality and increased heat stress attributable to warmer temperatures could lead to decreased livestock performance in this system, which is extensively used for livestock grazing. Mitigating the effects of increasing drought is critical to social and ecological stability in the region. Reduced stocking rates and/or a change in livestock breeds and/or grazing practices are general recommendations that could be implemented to cope with increased climatic stress. Ecological Sites (ESs) and their associated state-and-transition models (STMs) are tools to help land managers implement and evaluate responses to disturbances. The projected change in climate will vary depending upon geographic location. Vulnerability assessments and adaptation strategies are necessary at the local level to inform local management decisions and help to ameliorate the effects of climate change on rangelands. The USDA Southwest Climate Hub and the Natural Resources Conservation Service (NRCS) worked together to produce this drought vulnerability assessment at the Major Land Resource Area (MLRA) level: it is based on ESs/STMs that will help landowners and government agencies to identify and develop adaptation options for drought on rangelands.

Reduced forage quality and increased heat stress attributable to warmer temperatures could lead to decreased livestock performance in this system, which is extensively used for livestock grazing. Mitigating the effects of increasing drought is critical to social and ecological stability in the region. Reduced stocking rates, change in livestock breeds and/or grazing practices are general recommendations that could be implemented to cope with increased climatic stress. Ecological Sites (ESs) and their associated state and transition models (STMs) are tools to help land managers implement and evaluate responses to disturbances. The projected change in climate will vary depending on geographic location. Vulnerability assessments and adaptation strategies are needed at the local level to inform local management decisions and help ameliorate the effects of climate change on rangelands. The USDA Southwest Climate Hub and Natural Resources Conservation Service (NRCS) worked together to produce this drought vulnerability assessment at the Major Land Resource Area (MLRA) level based on ESs/STMs that will help landowners and government agencies identify and develop adaptation options for drought on rangelands. The assessment illustrates how site-specific information can be used to help minimize the effects of drought on rangelands and support informed decision-making for selecting management adaptations within MLRA 69.
