This dissertation is an attempt to analyse and address some of the many and complex issues revolving around protected area - community relationships. The success of these relationships are essential if the mission of protected areas are to be achieved. Due to large scale agriculture, high density populations and environmental degradation protected areas are often looked upon as a means to conserve biodiversity. It is for this reason that they play an important role in the natural environmental of South Africa. However, there is a growing realisation that protected areas will not survive unless they become relevant to the communities that surround them. These cOI11nlunities are often characterised by high density populations and low levels of infrastructural and economic development. These developmental requirements need to be considered by protected area management, and a dedicated effort is required by protected areas to assist in meeting these needs. However, the relationship between protected areas and C0111nlunities should not simply focus on meeting the developmental needs of the community, relationships need to allow for communities to participate in decisions and activities that directly impact of their lives. Benefits need to accrue to communities from protected areas for them to support the concepts of conservation. Benefits need to be tangible, intangible and empowering for them to have real meaningful impacts on the communities. Communities need to be actively involve in all aspects of the protected area management and links need to be forged between conservation and development, so that the socio-economic condition of those living closest to protected areas improves. This study uses the relationship between Mthethomusha Game Reserve and the surrounding Mpakeni conmunity, and the Pilanesberg National Park and the neighbouring Bakgatla community to investigate many issues, including the manner in which communities participate and benefit from conservation. The findings of this study reflect that the relationships between communities and protected areas are dependent on a number of factors including~ ownership~ socio-economic condition of the surrounding community~ institutional structures and capacity of the community formal agreements; history of the fonl1ati~n of the protect~d a~ea~ reliance on the protected area for survival and the meaningfulness and appropriateness of the benefits received from the protected area. The experiences of the two case studies has been analysed and compared to develop a theoretical model for community - protected area relationships. This model indicates the primary prerequisites which will contribute to effective and equitable relationships between protected areas and surrounding communities. / Thesis (M.Env.Dev.)-University of Natal, Pietermaritzburg, 1999.

Contested land-management plans make spatial data about values that people attach to the landscape necessary for federal land management. The study area for this project is the Olympic Peninsula, Washington, an area that is divided by a complex mosaic of land jurisdictions, including public lands administered by the National Park Service, National Forest Service, and Washington State, as well as interspersed tribal and private landholdings surrounding the perimeter. During the summer of 2012, I collected map and survey data from visitors at fourteen popular destinations around the Olympic Peninsula, including visitor centers, campgrounds, trail access points, and a ferry. Three research objectives were evaluated in my thesis: 1) determine a general typology of visitors, 2) understand what values and activities visitors associate with places in the peninsula, and 3) compare visitor data with resident data from the Human Ecology Mapping Project (HEM), a collaboration between the US Forest Service Pacific Northwest Research Station, the Institute of Culture and Ecology, and Portland State University. Analysis using ArcGIS included density and density hot spot calculations for a composite of the data as well as subsets based on types of visitors and individual values and activities. A majority of the participants were older males with higher education. Results indicate that visitors with different levels of familiarity spend time in different parts of the Peninsula. Aesthetic, recreation, and wilderness are the values most often included in the survey; hiking, non-cardio recreation, and sociocultural are the activity groups most often included in the survey. Visitors primarily mark places in Olympic National Park. Visitors, including those who live locally, responded in strikingly different ways than residents who participated in HEM. This research produced expected results that not only substantiate knowledge about specific places in the Olympic Peninsula, but also support theories about environmental cognition.

The Shenandoah Valley Civil War Sites Study Act of 1990 permitted the National Park Service (NPS) to investigate which unprotected battlefields (I5) might be preserved. After collaboration with the NPS, I was allowed to research the battlefield site of Opequon Creek (Third Battle of Winchester) in Frederick County, Virginia. In return, the NPS would receive a copy of this thesis for their use. A questionnaire, submitted to local residents, determined if a park was wanted, what type of park it might be, and what programming activities would be selected. A combination park of recreation, historical, and natural definitions was developed on the residents desires. The Opequon Creek Park process was developed first to alleviate any pre-NPS planning process influences. After Opequon Creek Park was designed, a process comparative analysis was made with the existing NPS model of Antietam Battlefield Park located in Sharpsburg, Maryland. The analysis determined if the NPS's planning process needed refinement. The NPS uses the "Planning Process Guidelines, NPS-2, 1985", to create each park's General Management plan (GMP). Two participatory stages, open houses and public hearings, were found mid-way through the development of Antietam's GMP. The Opequon process allows for participatory input at the start of park development but, did not allow for post design comments. Antietam's park definition was determined before public input was solicited and used based on early project funding requirements. The Opequon process, if implemented immediately upon a new parks legal creation, would save the NPS time and money in the research and development of new parks. Future parks will be carved from urbana as America's population doubles by 2038. The NPS needs a refined participatory planning method to do business with the public of today, the shrinking budgets of tomorrow, and the preservation of needed green space in the future. / Master of Landscape Architecture

National Parks bear greater implications than simply preserving or conserving pockets of landscape. They evoke values of conservation versus development, livelihood economics, environmental stewardship and personal enrichment; they fulfil positions in relation to the national and the international stage. Social characteristics are revealed though this comparative study of Banff National Park and the Cairngorms National Park. Perceptions of space, place and boundaries crucially imply different meanings to the people living inside the national park boundaries and those living outside the boundaries. 'Insiders' are long-term permanent residents for whom being in the park is a practical activity; 'outsiders' include scientists, conservationists, bureaucrats, and tourists, who take various ideological positions regarding the park's purpose. Both sides take a serious interest in the park and how it is managed and regard it as a place where they are 'at home'. Groups within these spaces considers their values and rights superior to others and conflict often arises. Non-violent means of gaining power as theorized by Foucault and Bourdieu, employing knowledge and discourse, are highly suggestive in the study of national parks. Discourse of nature is strategically significant as it influences purpose and policy that drive government's decisions on how the park will be managed - in this way discourse shapes the culture of how we use nature. Knowledge, as symbolic capital and as the basis for truth, sparks divisiveness - in particular scientific knowledge versus experiential knowledge. Changes to the exclusive North American model, such as those instituted in the Caimgorms, mark the increased social utility and inclusive nature of national parks. The challenge remains for park managers to reconcile values connected with nationalism and environmental ethics with values connected with local livelihoods.

This thesis examines community structure of cliff-top coastal heathlands in Botany Bay National Park, Sydney. Community properties of floristic composition, structure and species richness are investigated. This investigation is made in order to assess the justification for contemporary pre-emphasis in local studies on individual community properties. It is also made in order to assess the relative and independent contributions of individual properties to variance in overall community structure. It is also made in order to assess the relative utility of multi-property classifications in summarising community structure of cliff-top coastal heathlands. First, the presence of determinable structure in each property is assessed through multivariate classification of respective data sets. Secondly, a new model of community structure is developed in which the hypothesis that community structure is a function of common (shared) and independent (unique) variance in each of the three properties is assessed. This is achieved through application of variance partitioning using correspondence analysis techniques. Thirdly, a matrix combining variance in all three properties is classified. This classification is compared with those of individual properties in order to assess the hypothesis that more ecologically cohesive classifications than those of single properties are obtainable. The ecological significance (environmental relativity) of all classifications and variance components is assessed through examination of relationships with variance in 20 environmental factors which encompass variation in maritime factors, soil physical factors, soil nutrition factors and effects of time since fire. Classifications of individual properties showed the presence of determinable structure in each. Eleven floristic complexes, nine structural complexes and eighteen species richness complexes were recognised. Nineteen community complexes were recognised from the classification of the combined property matrix. All complexes were shown to differ significantly with respect to multiple environmental factors. Variance partitioning showed the presence of both independent and common variance components with respect to properties compared pairwise. These were all shown to differ in magnitude. Examination of environmental correlates showed ecological differentiation of all properties and most variance components. Maritime and fire factors provide a major axis of environmental differentiation for most properties and variance components. A second major axis was resolved with respect to physical soil factors. With the exception of variance in species richness, major soil nutrients were generally of secondary importance to community structure. Low soil nutrients may demarcate heathlands from other vegetation types. However, this study shows elevated importance of other major areas of environment for community structure within cliff-top coastal heathlands. Comparisons of environmental homogeneity characteristics between all classification systems showed the classification of the combined property matrix to be more ecologically robust than those of structure or species richness. Homogeneity characteristics of the combined classification remained statistically inseparable from that of floristic composition. However, studies provided some evidence suggesting greater robustness of the combined classification with regard to fine-scale variance in community structure. This thesis shows that variance in all major community properties of the studied vegetation to be of ecological significance. It also shows that this significance is differential with respect to properties and their variance components. Pre-emphasis on individual properties in syntheses of local systems thus involves the loss of ecological information. I thus conclude that if adequate ecological syntheses of cliff-top coastal heathlands are to be obtained which are appropriate to their scale of distribution and functioning in the Sydney area then inclusion of attributes of multiple properties is required. Equally, multiple sources of environmental variation need to be examined.

Throughout the Pacific, many species of echinoderms and molluscs have cultural value and are harvested extensively in subsistence fisheries. Many of these species are sedentary and often associated with distinct reef-top habitats. Despite the significance of reef habitats and their fauna for fisheries and biodiversity etc, little information has been available on the distribution of habitats and their influence on the reef-top fauna in the Cook Islands. This thesis developed a novel approach to assess the status of the shallow-water reef-tops of Rarotonga, Cook Islands, to provide critical information to fisheries and conservation managers. The approach used remote sensing (aerial photography with ground truthing) to map the spatial arrangement and extent of the entire reef-top habitats accurately, and historical wind data and coastline shape to determine the windward and leeward sides of the island. The benthic habitat maps and degree of wind exposure were used to design and undertake a stratified sampling programme to assess the distribution and abundance of the epibenthic macroinvertebrate fauna of the reef-top. I quantified the distribution and abundance of the epibenthic macroinvertebrates and how they varied with habitat, assessed the effectiveness of a traditional ra�ui (marine protected area) for conserving stocks of Trochus niloticus and other invertebrates, and investigated the reproductive biology and impacts of traditional gonad harvesting on Holothuria leucospilota. There were four major habitat types (rubble/rock, sand/coral matrix, algal rim and sand) identified, the most extensive being rubble/rock (45%) and sand/coral matrix (35%). The degree of exposure to winds was found to correlate with the reef development and habitat distribution. The assemblage composition of each major habitat type differed significantly from every other habitat. The rubble/rock habitat had the greatest substratum heterogeneity and structural complexity, and the highest number of species and individuals. The overall abundance of the fauna was dominated by holothurians (68%) and echinoids (30%), while Trochus niloticus and Tridacna maxima accounted for the remaining 2% of the total invertebrate assemblage. Clear habitat partitioning was also found for adult and juvenile Trochus niloticus and Tridacna maxima. In the traditional fishery for Holothuria leucospilota, the mature gonads of males are harvested by making an incision in the body-wall of the animal, removing the gonads and then returning the animal to the reef to allow regeneration. Monthly collections of H. leucospilota were used to describe the reproductive biology of this species. Gametogenesis and spawning were synchronous between the sexes and spawning occurred annually during summer, when water temperature and photoperiod were at their highest. Although the incision in the body-wall and gonad removal had no impact on the survival of H.leucospilota in experimental cages, their body weight, and general sheltering and feeding behaviors were affected. Gonads took at least 41 days to start regenerating, suggesting a considerable delay in the spawning of fished individuals. In 1998, five Rarotongan communities re-introduced the traditional ra�ui system of resource management, prohibiting all fishing and gathering from their reefs. The performance of the Nikao ra�ui, which had been put in place to allow trochus stocks to increase, was investigated. Comparisons of macroinvertebrate assemblage composition and species density were made between three fishing treatments, i.e. fished areas adjacent to the ra�ui, within the ra�ui after two years of protection, and in the ra�ui after it had been lifted for three weeks to allow a commercial trochus harvest. Analysis of variance on the count data for the twelve most abundant species, and non-metric multi-dimensional scaling indicated that there were no differences in the microhabitat or the invertebrate assemblage composition between the three fishing treatments. However, there were significant differences between the rubble/rock and sand/coral matrix habitat types. The results on the effectiveness of the Nikao ra�ui are equivocal, due to the small sample size, and the variability between samples which was highlighted by the wide confidence intervals. This study highlights the importance of habitat to the macroinvertebrate fauna of the reef-top and the need for accurate habitat maps to increase the cost-effectiveness of future resource surveys, to provide information to management, and for the design of Marine Protected Areas. The mapping and survey methods must be reliable and repeatable in terms of the limitations of time, and the availability of expertise, funding and resources. The results provide important information for fisheries and conservation managers of Rarotonga and other Pacific Islands to better design rigorous sampling programmes for monitoring the status of reef-top resources, and for evaluating and planning Marine Protected Areas.
