This study documents the development of the Queenstown nature reserve as a cross-curricular tea~hing resource. Participants in the project included the researcher, the municipality nature conservation officer and the senior Geography and Biology teachers from five high schools in the town. A modified action research approach was adopted. Data was collected from workshops and interviews and then analyzed. The conclusion of the research was that the participants perceived that the project had been worthwhile and was to be continued. The nature reserve is now more widely and usefully used

Limpets are harvested by people in South Africa, but are selected in terms of species and size. The effects of marine reserves on the biology of commonly exploited (Helcion concolor and Scutellastra longicosta) and rarely exploited species (Cellana capensis and Scutellastra granularis) were investigated on the southeast coast of South Africa at two reserve and two non-reserve sites. For each species, a 4-way nested ANOVA was used to test the effects of month, reserve, site (nested within reserve) and area (nested within site and reserve) on population density, size structure and recruitment of these limpets. The data were collected monthly over 20 months. The overall results indicated a gradient of exploitation among species, S. longicosta was the most heavily exploited species and S. granularis the least exploited species. However, there was also a gradient of exploitation between reserves and non-reserves. Xhora was the most heavily exploited site while Nqabara was less heavily exploited. Of the two reserve sites, Cwebe had more poachers than Dwesa. In most analyses, the month x area (reserve (site)) interaction was significant. However, this was largely an artifact due to comparisons of areas in different sites and significant differences between areas within sites occurred in relatively few months. Densities were greater inside reserves for all species except C. capensis. For S. longicosta and H. concolor this was expected but not for S. granularis and the result possibly reflects its opportunistic exploitation in the absence of the preferred species or indirect effects of reserves. Commonly exploited species and the rarely exploited C. capensis clearly showed greater mean and maximum sizes in reserves but there were month/site (reserve) interactions. Months with significant differences between reserves and nonreserves in both mean and maximum sizes generally occurred more often for commonly exploited than rarely exploited species, but C. capensis showed the strongest reserve effect on maximum size. Interview surveys showed that, although not normally exploited, C. capensis is sometimes mistaken for H. concolor and this suggests that large individuals are unintentionally harvested outside reserves. There were no significant reserve effects on recruitment for any species. Although Xhora had the lowest densities and limpet sizes, it showed the highest recruitment especially for S. longicosta, suggesting that larvae can be transported far from where they are released and settle in non-reserve sites regardless of adult densities. Reserve as a main factor was not significant for the rarely exploited species, but there was a significant month x reserve interaction, with non-reserves having greater GSI values than reserves in most months. Growth rates were examined using individual tagging and cohort analysis. The two techniques gave different results, with individual tagging giving higher growth estimates than cohort analysis. Except for the territorial species S. longicosta, growth was higher in non-reserves and inversely correlated with population density. Mortality estimates using the Cormack-Jolly-Seber model indicated that the rarely exploited species had significantly greater capture probabilities in reserves while no significant reserve effects were observed for the commonly exploited species. Reserve effects on survival probability were significant only for S. longicosta, with reserves being greater than nonreserves and no significant effects for any other species. Enhanced survival in reserves was attributed to the effects of human exploitation. In theory, marine protected areas show increases in densities, sizes and reproductive output of exploited species, but the present results revealed that the efficacy of reserves depends on the status of the species, not only whether it is exploited or non-exploited, but also whether it is territorial.

The recent establishment of an impressive network of national parks within first the Soviet Union and then post-Soviet Russia can be viewed as representative of ongoing shifts in relationships between valuations of nature and of societal organization and empowerment. With dissipation of the country's centralized administrative structures, the designation of national parks has repeatedly been used to support regional claims to territorial autonomy under the auspices of environmental protection. Site selection, however, has been motivated primarily by attachments to the specifics of place and attendant proclamations of self-identity rather than to normative ecological or recreational national park criteria. As a consequence, Russian national parks embrace complex matrices of historical, cultural and natural landscape characteristics reflective of their respective constituencies. Appearing first in the outlying Republics, the national park formation process diffused inwards to the Russian heartland and eastwards into Siberia. This sequential development, not by chance, has mirrored the devolution of Soviet sovereignty and the deconstruction of its empire. Two national parks, Pribaikalski and Zabaikalski in the Lake Baikal region of south-central Siberia, have served as primary research sites for examining the validity of the above concepts and for observing and analyzing the processes involved. To maximize informational and perceptual access and to study site/societal interactions, a variety of constituencies have been incorporated into the study through extensive multitiered participatory roles. At an operational level, these activities have emphasized international agency/NGO consultancies, the development of a park-directed, village-based ecotourism program and the founding of a wider-ranging “Friends of the National Parks Society.” Research results have supported the contention that Russian national parks are primarily a product of regional socio-political forces intent on preserving representative natural/cultural landscapes rather than the result of centralized decision-making processes prioritizing recreation, education, or biodiversity objectives. Given the persistence of societal flux, the sites will continue to be highly susceptible to the influences of stakeholder/constituency interests and empowered individuals. / Graduate

This thesis explores Recreational Carrying Capacity (RCC). The investigation looks at the theory of RCC, and trends in recreational use and management to make a first estimate of the RCC of Garibaldi Provincial Park, British Columbia, Canada. An extensive literature review is used to synthesize the social, ecological and managerial factors called for in RCC theory; and to summarize relevant aspects of park policy and recreation trends. This review serves as a foundation for adapting a RCC model from the literature. The model is then used to estimate the RCC of the developed backcountry areas of Garibaldi Provincial Park. The emphasis of the thesis is on the ecological component of RCC: a bio-climatic zone inventory, a soil capability survey, and a visual impact assessment are all undertaken to build an estimate of the ecological sensitivity of the study area. The model also uses social influences and BC Parks policy to assist in the formulation of the RCC for the study area. The RCC estimates derived are not precise because of weaknesses in the data base. Nevertheless, the estimates do indicate that the most desirable areas for recreation within Garibaldi Park have reached or exceeded the capability of the biophysical resources of those areas to sustain the recreational activities undertaken. As important as the RCC estimation is the identification of biophysical limitations of the study area. These limitations call for careful site selection in the development and management of Garibaldi Park to protect the biophysical resources which attract recreational use. If the model is to be of greater assistance in park planning and management then more precision is required in the investigation. Increased precision requires dividing the broad bio-climatic zones into sub-zones or micro-zones to allow site and route selection for managing the study area. RCC theory and the RCC model used are useful as planning tools because of the comprehensiveness required by the theory and the explicitness of the values used within the model. However, this comprehensiveness demands a large data base which is not available in the case study of Garibaldi Park. This points to the need for further research if RCC theory and the model used are to be of utility to park planning in B.C. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate
