Each day the joint managers of Uluru-Kata Tjuta National Park receive packages of returned rocks and sand that have been removed from the landscape by visitors as a souvenir of the place. The returned objects are sent from people all over the world as the stories of this phenomenon travel well beyond the Park boundaries. Known within the Park as the ‘sorry rocks’, these returned objects and their accompanying letters of apology reflect the different ways in which people engage with the landscape and interpret their surrounds. In this research, the sorry rocks have been used as a medium for examining the complex relationships that exist between visitors, heritage management and interpretation particularly in cross-cultural settings that recognise Indigenous cultural heritage.

[Truncated abstract] The ecological effects of marine protected areas (MPAs) in temperate ecosystems are poorly understood relative to their tropical counterparts. The limited number of rigorous empirical studies supporting existing theoretical models, increasing public awareness of the importance of marine conservation strategies and legislative requirements to review management effectiveness provide further impetus to study temperate MPAs. Investigations should consider confounding effects of natural variability if MPA effects are to be clearly demonstrated. This research helps to address these needs by investigating the short term effects of sanctuary zones (no-take MPAs where fishing is prohibited) and wave exposure at Marmion Marine Park, Western Australia. The three sanctuary zones at Marmion Marine Park are extremely small (0.061 0.279 km2) compared to most reported in the literature. The sanctuary zones are nested within a larger, fished zone (94.95 km2). The sanctuary zones have been protected from fishing since the year 2000. A post-hoc, asymmetrical sampling design was used in this study and involved surveys of fishes, mobile invertebrates and macroalgae at one sanctuary zone and two fished sites (controls) at each of three successive, subtidal reef lines. The three reef lines are exposed to a gradient in wave energy. The size structure and abundance of the heavily exploited Panulirus cygnus (Western Rock Lobster) were positively affected by protection from fishing in sanctuary zones, despite the highly mobile nature of this migratory species. The mean abundance of legal size lobsters was higher in sanctuary zones compared to fished sites during an interannual study (2003, 2005 and 2006). The total abundance of lobsters and the mean abundance of legal size lobsters were higher at inshore and offshore sanctuary zones compared to fished control sites during a 2005/2006 fishing season study. These zoning effects did not vary with the time of survey. ... Furthermore, the abundance of large lobsters in sanctuary zones decreased with the duration of the 2005/2006 fishing season. Similarly, it is likely that sanctuary zones are too small relative to the movement of fishes to adequately protect stocks of some targeted species. The small sanctuary zones at Marmion are unlikely to offer protection to highly mobile species over the long term. And finally, ecological assemblages within each level of wave exposure are distinct. Consequently for each assemblage type, the current reserve design does not include replication of sanctuary zones and does not offer any 'insurance' in the event of isolated impacts affecting a particular zone. This study has identified the benefits and deficiencies of the design and function of small no-take temperate MPAs in Western Australia. An increase in the size and number of sanctuary zones within each wave exposure level will help to address the v shortfalls of the zoning scheme and enhance the conservation benefits of management at Marmion Marine Park. More generally, this study demonstrates that the mobility of the species to be protected from fishing should be considered when designing MPAs. Lessons learned from this work will be beneficial for the future management and conservation of resources in the region and elsewhere.

Coral reef ecosystems are the most diverse on earth, and their subsistence is being threatened by natural and adverse anthropogenic patterns and processes. In an effort to understand and protect these marine environments, several programs have outlined strategies and initiatives. For example, the United States Coral Reef Task Force���s Mapping and Information Working Group has outlined a specific goal to map all coral reefs below 30 m depth by 2009. This study contributes to achieving that goal for three sites around the island of Tutuila, American Samoa, lying in the heart of the South Pacific. American Samoa, a U.S. territory, is home to the Fagatele Bay National Marine Sanctuary, the smallest and most remote in the United States, and to the National Park of American Samoa. Extensive modern scientific surveys were implemented around the territory in 2001 and have since continued and increased. The presence of protected areas and the existence of scientific data collected with state of the art technology have made the site a priority for the Coral Reef Task Force. In this study, methods for classifying surficial seafloor characteristics as bathymetric position index (BPI) zones and structures were developed and applied to the study sites. BPI zones and structures were classified by using algorithms that combine high-resolution (1 m) multibeam bathymetry and its derivatives: bathymetric position index at multiple scales and slope. The development of algorithms and the classification scheme involved the use of historical and current classification studies and three-dimensional visualization. In addition, the BPI zones and structures were compared to limited biological, geological, and physical attributes recorded during accuracy assessment surveys (photos) and towed diver surveys (video). A rugosity (surface ratio) analysis was added to the study to give a picture of the seafloor roughness. The BPI zone and structure classifications overlap and extend existing classifications from Ikonos satellite imagery for water depths shallower than 30 m. Methods, data and classifications developed and applied in this study will be available to the public as a benthic habitat mapping tool (ArcGIS extension), in an online GIS data archive, and on a compact disc attached to this thesis. They contribute to a broader understanding of the marine and coastal environment and will serve as a baseline of information for benthic habitat mapping and future biological, ecological, and geological surveys. The baseline gives a good indication of characteristics that may indicate areas of high biodiversity. The final maps presented here are especially useful to managers, researchers and scientists that seek to establish and monitor a wider and more effective network of marine and coastal protection. / Graduation date: 2005

Sweden has had laws protecting nature for about a hundred years. In this paper the views of nature and the values that serve as a rationale for protective measures are analyzed as results of a social process characterized by the dialectic relationship between institutions and discourse. Critical discourse analysis (CDA) is used to study this relationship and the discursive practices used by institutions, which reproduce or reshape views of nature that define the relationship between society and nature. Institutional design contributes to shaping discourse in the field of nature protection, while being originally shaped by discourse. In Sweden, the national park is an institution that reproduces a view of nature as the wild and untamed opposite of society, and the natural reserves reproduce a view of nature as holder of a multi-faceted set of values intertwined with society. However, the most recently formed national park, the marine national park of the Koster sea includes resource values that threaten the hegemony of arcadian discourse within the institution and indicates social change.

In upcoming decades, the conservation and sustainable use of coastal and marine resources will become a major political and environmental challenge, as two-thirds of the world's population lives in coastal zones. The issue will likely become more problematic in developing countries, where an important number of coastal inhabitants still rely on marginal extractive activities such as fishing, farming and cattle ranching for subsistence, and where the rural poor's demand for development often lead to unsustainable extractive practices. Thus, innovative solutions need to be developed to ensure the long-term conservation and sound management of marine and coastal resources. This Masters thesis addresses the case of Coiba National Park, a marine protected area located in the Gulf of Chiriqui, Panama, and its relationship with coastal fishing and farming communities located at its outskirt. Particularly, this thesis aims to discover the drivers that pushed an important number of coastal agro-pastoralists of Coiba National Park's buffer zone to switch to artisanal fishing over the past three decades, and to determine the social, economic, and environmental impacts that resulted from that switch. In addition, this thesis analyses the relationship between Coiba National Park's authorities and buffer zone communities, and how this relationship has evolved over the years as more and more resource-users exploit the marine resources of the park. Finally, this work analyses Coiba National Park's current management strategy, how park authorities have been able to adapt their planning and management activities over the years, and explores alternatives to improve Coiba National Park's management strategy so that it can better adapt to the ever changing social, economic, and environmental conditions in which Coiba National Park's buffer zone operates.

For over a century, wildlife in Southern Africa has come under the exclusive management of states, which tends to centre on the exclusion of local communities from wildlife areas. In many cases, this approach has led to the hostility of wildlife management policies by excluded communities. This widespread dissatisfaction has caused a paradigm shift in conservation thinking towards a more community-based conservation (CBC) approach. A major assumption of this new approach is that providing socio-economic benefits on a sustainable basis to formerly excluded communities will result in conservation. Indeed, some advocates of this management regime have stressed community incorporation and inclusion as the only path to conservation. As a result, numerous CBC initiatives have been implemented throughout the African sub-region over the past ten years with varied success. As there is no alternative to the CBC concept that attempts to enhance all three elements, namely the economic, social and biological components, of the sustainable development premise in conservation areas, it is imperative to ensure that CBC initiatives are monitored and evaluated in order to determine what the recurring problems and challenges are in implementing and running such initiatives so as to achieve the three sustainable development goals. By establishing what these recurring challenges are during the implementation process, a broad framework of necessary principles, criteria, pre-requisites and co-requisites can be established to guide future CBC initiatives. The purpose of this study is to identify the successes, challenges and problems that have either enhanced or detracted from the socio-economic and biological elements of CBC initiatives during the implementation processes of different projects. Previous documented project examples from around the sub-region, as well as two case study examples of CBC initiatives in KwaZulu-Natal, namely the Mabaso Community Game Reserve and the Usuthu Gorge Community Conservation Area, are used in this thesis to best determine how to enhance the social and economic elements of the sustainable development premIse III order to achieve, in theory, the biological components necessary for a successful conservation strategy. The findings within this study, from the case study examples and secondary research, show that there are several recurring challenges and problems shared by initiators of CBC initiatives throughout the sub-continent. Issues include long project implementation periods due to government bureaucracy, planning procedures and the necessity to gain community support; debates over devolution of authority to local municipalities or tribal authorities; the risks of elite capture and/or the free rider concept whereby individuals do not change their hunting practices despite communal benefits accruing from wildlife conservation; community participation and benefit distribution; as well as the need to have clear communication channels between the community and the project implementers. The main conclusions drawn from this study emphasise several needs necessary for making CBC initiatives sustainable for the long term. Firstly, CBC initiatives need to conserve as well as create a variety of different ways for communities to earn a living and to minimise any disruption by CBC projects of pre-existing livelihood strategies carried out by local residents. Secondly, there needs to be a provision of outside assistance to facilitate local projects and to ensure the development of the necessary skills for local communities to eventually take on the initiatives themselves. Thirdly, clearly defined property rights, as well as conflict resolution mechanisms and the enforcement of any rules and regulations are further crucial criteria. Fourthly, it is important for communities to avoid exploitation and to maximise any benefits accruing from private investors utilising local community resources by developing favourable legal contracts. Fifthly, it was found that the inclusion of tribal structures in both the case study examples increased the trust and feeling of ownership by the respective communities. Finally, it was found that CBC projects require specific locations and the right criteria to be in place for their successful implementation. Not all communities or communal areas meet these criteria, which is why CBC should be seen more as an important and necessary supplement to conservation strategies as opposed to a holistic conservation policy tool. / Thesis (M.Dev.
