In addition to their original purpose as recreational areas, urban parks provide important habitats for species living in urban settings. Reconciling recreational and environmental goals is problematic, especially for park planners. RIM Park, in Waterloo, Ontario, is an example of this attempted reconciliation, where planners and managers attempted to conserve herpetofauna in a provincially significant wetland. However, this area includes a paved nature trail used by hikers, in-line skaters and cyclists and is adjacent to a golf course (which lies within the boundaries of the park). Herpetofauna breeding ponds were constructed and a series of culverts and clearspans included in order to provide reptiles and amphibians with safe passage under the trails. My objective was to determine whether these measures have been effective, whether the park sustains a viable population of Northern Leopard Frogs, and what factors influence frog populations in the park. Two spring field seasons involving mark and recapture techniques were attempted to estimate population sizes of Northern Leopard Frogs at RIM Park, as well as control sites. In both seasons, a control site was a cedar swamp 14 km to the west of the park within an Environmentally Sensitive Policy Area in Waterloo city limits affected by housing development and shared trails. Also within Waterloo city limits, a storm water management pond 8 km to the west was added in field season two. In 2005 (field season 1), because there was a serious drought almost no Northern Leopard Frogs were captured at the two sites examined ? RIM Park and the cedar swamp. In 2006, the more "normal" weather conditions revealed that RIM Park had significantly fewer Northern Leopard Frogs than either of the control sites. Given the lack of data in year 1, I compared the 2006 results to seven years of monitoring reports on RIM Park from consultants. The 2006 data were consistent with previous reports of small Northern Leopard Frog populations at RIM Park. Mark and recapture sessions revealed relatively low numbers, with a catch average of 4. 33 (SD = 1. 15). Calculations revealed an estimated population of 23 (SE = 13. 42). The highest number of observed Northern Leopard Frogs ever recorded at the same location in consulting reports is 5. It is likely that the ponds at RIM Park do not support breeding in Northern Leopard Frogs as the only adults caught were late in the season, during the last week of May, and adults likely were transients from the nearby wetlands and uplands. It is possible, given the historical monitoring data, that the Northern Leopard Frogs were long absent from RIM Park because of intensive farming activities that had replaced the wetlands, and that construction of the golf course and trails further precluded colonization. The lack of adult frogs in the breeding ponds and the lack of dead or injured frogs on the trails or golf course support the hypothesis that the trails are not presently causing frog mortality. It is possible that the frogs are avoiding recolonizing the trail and golf course area. It is also likely that the breeding ponds need to be deepened and only then will it be apparent whether the frogs will colonize the ponds, lay eggs, and use the clearspans and culverts. Recommendations include a shift in priorities to put the emphasis on restoration, a discussion of restoration options (including a possible restoration plan), possible improvements in amphibian monitoring techniques (such as reducing the reliance on audio methods), and general suggestions for urban park planning and management.

Practicing science in a policy context demands careful attention. This research presents backcountry campsite conditions found in Shenandoah National Park during 1992. It fuels a policy process grounded in Limits-of-Acceptable-Change (LAC). This context provides an opportunity to critique natural resource science within an LAC process and to illustrate the applicability of techniques from disciplines as diverse as educational testing and policy sciences. The condition, location, and legality of 743 backcountry campsites are reported, as revealed during a census completed using methods from recreation ecology. To assess the consistency and precision of campsite surveyors, techniques from educational measurement are adopted, including generalizability theory and decision studies. For each indicator, these techniques reveal the consistency of raters, their ability to distinguish between unique campsites, and whether raters are systematic. These three components were found to vary considerably for different indicators, reflecting the appropriateness of each indicator for justifying management decisions. In addition to traditional description of survey results, campsite condition indicators of 220 campsites with bare soil are reintegrated using cluster analysis. Seven distinct types of campsites with bare soil exist in the park. This approach should facilitate policy makers’ understanding of findings, and improve investigators’ comprehension of survey data. Recommendations include adopting a multiple strategy policy for managing backcountry campsites in Shenandoah National Park, continuing efforts to adapt generalizability theory to natural resource monitoring, and applying two phase research designs that combine the strengths of both census and survey in an efficient manner guided by generalizability theory. / Master of Science

Thesis (MPhil)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: There is a shift by conservation authorities in post-apartheid South Africa away from management strategies based on law enforcement towards strategies aimed at facilitating local community participation in the management of natural resources. South African National Parks has established community forums in order to facilitate better communication with the communities neighbouring it parks, especially around issues of natural resource consumption. However, at its largest Park, the Kruger National Park, a pervasive miscommunication between the Park and the communities appears to exist despite the ongoing activities of its forums. This study attempted to identify what miscommunication, if any, was occurring between three groups of participants in the Conservation Discourse related to the Kruger National Park environment. The participants were (i) South African National Parks (SANParks) conservation managers, (ii) Kruger Park community outreach officials, and, (iii) members of local communities settled on the borders of the Kruger Park. Specifically, the study was interested in how different perceptions of various participants, who also represent different cultural communities, were foregrounded in relation to different communicative goals. It is suggested that an understanding of where the different Discourses diverge can help identify where possible misunderstandings are occurring which may be resulting in communicative problems. My primary research questions were: (1) how do different communities of practice take part in and construct Conservation Discourse related to the Kruger Parks conservation goals, in particular, those related to the use of natural resources; and, (2) how do members of at least three interest groups construct their own identities in relation to conservation matters in the course of various discursive events where SANParks conservation programmes, particularly those related to the use of natural resources, are topicalised. My assumption was that the Parks conservation officers would have a common Conservation Discourse, and that the local communities would have a common discourse but one which deviates entirely from that of the Parks. From 23 September 2008, I conducted three semi-structured interviews with the Parks conservation officers, I was an observer of a Park departmental meeting as well as a Park Forum, and I conducted a focus group with eight members from one of the local communities. This approach enabled me to collect data from a number of different types of communicative events in order to collate a multidimensional picture of the complete Discourse on Conservation. A number of different Conservation Discourses were identified, some of which present significant discrepancies, and which, as in the case of the two of the departments, may be contributing towards what appears to be a serious breakdown in communication. The communities show that while they are supportive of the populist concept of nature conservation, they are completely unaware of the Parks conservation policies. This lack of awareness indicates a failure of the existing communication between the Park and its neighbouring communities despite the Park Forums having been set-up. Finally, the different discourses also appear to be resulting in misunderstandings and feelings of animosity between the different participants. / AFRIKAANSE OPSOMMING: In post-apartheid Suid-Afrika beweeg bewaringsliggame weg van bestuurstrategieë wat op wetstoepassing gebaseer is, na strategieë wat daarop gemik is om die plaaslike gemeenskap se deelname in die bestuur van natuurlike hulpbronne, te fasiliteer. Suid-Afrikaanse Nasionale Parke het gemeenskapsforums in die lewe geroep om beter kommunikasie met die gemeenskappe wat aan sy parke grens, te bewerkstellig, veral rakende kwessies rondom die verbruik van natuurlike hulpbronne. By die grootse Park, te wete die Kruger Nasionale Wildtuin, kom dit egter voor asof miskommunikasie endemies is tussen die Park en sy aangrensende inheemse gemeenskappe, ten spyte van die forums se aktiwiteite. Hierdie studie het nagegaan watter miskommunikasie, indien enige, tussen drie groepe deelnemers aan die Bewaringsdiskoerse rondom die Krugerpark, plaasgevind het. Die deelnemers was (i) Suid- Afrikaanse Nasionale Parke (SANParke)-bewaringsbestuurders, (ii) Krugerpark Gemeenskapsuitreikbeamptes, en (iii) lede van plaaslike gemeenskappe wat op die grense van Krugerpark gevestig is. Die studie het spesifiek gekyk na hoe verskillende persepsies van die onderskeie deelnemers, wat ook verskillende kulturele gemeenskappe verteenwoordig, in die diskoerse op die voorgrond geplaas is afhangende van verskillende kommunikatiewe doelwitte. Daar word voorgestel dat begrip van waar die verskillende diskoerse uiteenloop, kan help om te identifiseer waar moontlike misverstande wat tot kommunikasie-probleme lei, ontstaan. My primêre navorsingsvrae was: (1) hoe neem verskillende gemeenskappe wat rondom gedeelde praktyke gevestig is deel aan Bewaringsdiskoerse wat die Krugerpark se bewaringsoogmerke (en veral daardie oogmerke wat met die gebruik van natuurlik hulpbronne te make het) en hoe konstrueer hulle daardie Diskoerse; en (2) hoe konstrueer lede van ten minste drie belangegroepe hul eie identiteite vis à vis bewaringskwessies in die loop van verskeie diskursiewe gebeurtenisse waar SANParke se bewaringsprogramme, veral daardie wat met die gebruik van natuurlike hulpbronne te doen het, bespreek word. My aanname was dat die Park se bewaringsbeamptes 'n gemeenskaplike Bewaringsdiskoers sou hê, en dat die plaaslike gemeenskappe 'n gemeenskaplike Diskoers sou hê wat heeltemal van die Park s'n verskil. Ek het van 23 September 2008 drie semi-gestruktureerde onderhoude met die Park se bewaringsbeamptes gevoer, ek was 'n nie-deelnemende waarnemer by een van die Park se departementele vergaderings asook by 'n Park Forum, en ek het 'n fokusgroep met agt lede van een van die plaaslike gemeenskappe gelei. Hierdie benadering het my daartoe in staat gestel om data van verskeie tipes kommunikatiewe gebeurtenisse in te samel, om sodoende 'n multi-dimensionele beeld van die volledige Bewaringsdiskoers saam te stel. 'n Aantal verskillende Bewaringsdiskoerse is geïdentifiseer, waarvan party noemenswaardige diskrepansies toon en wat, soos in die geval van die twee departemente, moontlik bydra tot wat lyk na 'n ernstige breuk in kommunikasie. Die gemeenskappe toon dat, hoewel hulle die algemene konsep van natuurbewaring ondersteun, hulle heeltemal onbewus is van die Park se formele bewaringsbeleid. Hierdie gebrek aan 'n bepaalde soort bewussyn dui op mislukking van die bestaande kommunikasiestrukture tussen die Park en aangrensende gemeenskappe, ten spyte van die instelling van die Park Forums. Uiteindelik blyk dit dat die verskillende Diskoerse ook lei tot misverstande en gevoelens van vyandiggesindheid tussen die verskillende deelnemers.

The tourism industry is an extremely competitive industry which is mainly caused by the ever changing needs of tourists. However, despite the constant change in tourist behaviour, violent terrorist attacks on countries across the globe and the weakening of the world economies, the tourism industry showed significant growth over the last few decades. The fast growth rate of tourism has also lead to the tourist being more aware of ecotourism destinations and the key role these destinations play in conserving the natural and cultural environments in the midst of globalisation and urbanisation. The pressure on ecotourism destinations such as national parks is increasing as more and more natural land are being taken up for urban development. In the case of South African National Parks (SANParks), the decrease in government funding pressurizes the resources and national parks have to identify ways to generate their own income through tourism activities. SANParks manages 22 national parks across South Africa with the aim to conserve South Africa’s biodiversity, provide recreational activities for tourists and build long-term relationships with the local communities to enhance the communities’ quality of life. Hence, in order to remain competitive it is important to determine the parks' competitive advantages. Therefore the aim of this study was to develop a competitiveness model for SANParks by using the Kruger National Park as case study. The Kruger National Park is not only one of the largest and most recognised national parks in the world, but also boasts with a large variety of fauna and flora, variety of accommodation facilities such as bush lodges, chalets and camping facilities as well as various tourist activities. The literature review indicated that destinations differ from each other and therefore ecotourism destinations such as national parks would have a distinct set of competitive advantage factors. However, these factors can only be determined if the needs of tourists are anticipated and park specific products and services are developed to satisfy the needs of visitors to the park and ultimately lead to tourist loyalty. Once a competitive position has been established, a national park can obtain benefits such as an increase in tourist numbers and revenue delivery of high quality products and services at the park as well as trigger a higher quality of life for the local community. If managed accordingly, the park might experience sustainable growth as well as increased profit margins. The data for the study was collected by means of a questionnaire survey at four of the Kruger National Park's rest camps during the period 26 December 2013 and 4 January 2014 which is the festive season in South Africa. The rest camps that were included in this survey were Olifants (74 questionnaires); Skukuza (213 questionnaires); Lower Sabie (98 questionnaires) and Berg-&-Dal (51 questionnaires). A total of 436 completed questionnaires were administered and further analysed. Descriptive statistics were used to profile the respondents while two factor analyses were done on the competitive advantage factors and tourist motives for travelling to the Park. The factor analyses identified five competitive advantage factors of which Wildlife Experiences and Marketing and Branding were regarded as the most important factors. The other three competitive advantage factors were Accommodation and Retail, Visitor Management and Suprastructure and Amenities. Four motivational factors were identified namely Experience and Relaxation, Lifestyle, All-Inclusive Destination and Value. The identified factors were further used in an ANOVA analysis and the results showed that socio-demographic characteristics such as home language, province of residence, level of education and marital status have all significant differences based on the five competitive advantage factors as well as the four motivational factors The t-test analysis presented a few statistical significant differences between the independent variables or group of individuals. These differences were based on the respondents’ demographic and behaviour characteristics with regards to the competitive advantage and motivational factors. However, the strongest statistically significant differences were based on the behavioural characteristics of tourists travelling with children to the Park, Wild card holders, tourist reading magazines, previous visits to the Park and differences between tourists making use of chalets and camping facilities. A Structural Equation Model was applied to confirm the results that were obtained from the analyses. The SEM indicated that tourists’ motivations have a significant influence on the factors that tourists identified as competitive advantage factors for the Kruger National Park. This research made three distinct new contributions. Firstly, competitive advantage factors were specifically identified for ecotourism based destinations such as national parks from a demand side. Also, the tourists motivation for travelling proved to hugely influence these competitive advantage factors. Secondly, a competitiveness model was developed specifically for national parks within South Africa. The proposed model could assist national parks across South Africa to obtain a competitive advantage among its competitors based on park specific factors. Lastly, the concept of competitiveness has not yet been applied within the ecotourism and nature-based tourism destinations context. This study described the concept of competitiveness with the focus on national parks as ecotourism destinations and the aspects that need to be taken into consideration when analysing the concept in such a context. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2015

Les recherches multiculturelles en management prévalent sur les organisations à but lucratif, tandis que les études interculturelles sur les zones naturelles protégées constituent encore un domaine relativement peu exploité. Cette thèse propose des modèles interculturels adaptés (issus du modèle existant de Hofstede, complétés des concepts appartenant aux domaines du marketing et du management) pour l’analyse de la gestion de parcs et des expériences des visiteurs vécues au sein des parcs naturels européens (protégés). Parmi les différentes méthodes utilisées, les plus pertinentes s’avèrent être la conduite d’entretiens semi-directifs avec des dirigeants de parcs et l’enquête effectuée auprès des visiteurs, tandis que l’analyse de documents et les observations complètent nos résultats. À partir de nos analyses sur la gestion des parcs, les parties prenantes, les activités outdoor et les expériences des visiteurs, nous concluons que les différences culturelles influencent à la fois la gestion du parc et les expériences des visiteurs, mais d’une façon distincte. Bien que les différences culturelles soient constatées entre les visiteurs français et hongrois, leurs modes de consommation montrent des signes de facteurs internationaux/globaux, tandis que le choix des activités physiques et des caractéristiques démographiques s’avèrent également façonner les expériences des visiteurs. Les opérations et les directions de la gestion des parcs ont également confirmé être influencées par les différences culturelles dans une plus large mesure, bien qu’elles soient aussi déterminées par les caractéristiques géographiques des sites naturels. Cependant, les considérations managériales sont aussi liées au comportement du visiteur, au contexte législatif et aux caractéristiques géographiques du site. / Cross-cultural investigations in management prevail over those on for-profit organizations, while intercultural studies on protected natural areas is a relatively untapped field of research. This thesis proposes cross-cultural models (adapted from the existing model of Hofstede, along with marketing and management concepts) for the analysis of the park management and visitor experiences at (protected) European natural parks. Among the various methods used, the most relevant were the semi-directed interviews with actors of the park management and the visitor survey, while document analysis and observations also completed our findings. Using our analysis of the park management, stakeholders, physical activities, and visitor experiences, we concluded, that cultural differences influence both the park management and visitor experiences, though, in different ways. While cultural differences were found between the French and Hungarian visitors, their recreational consumption patterns show signs of international/global considerations, whereas the choice of physical activities and demographic characteristics also proved to shape visitor experiences. In turn, operations and directions of park management were confirmed to be affected by cultural differences to a larger extent, while these were also influenced by the geographical characteristics of the natural sites. However, managerial considerations were found to be interrelated with the visitors’ behavior, the legislative background and the geographical features of the area.

Of the seven pelican species found world wide, only the Great White Pelican (Pelecanus onocrotalus) and the Pink-backed Pelican (P. rufescens) are found in Africa. The KwaZulu-Natal province of South Africa supports only one breeding site for each of these species, and both sites represent the southern most breeding colonies for the two species in the eastern region of Africa. These nesting sites fall within the Greater St Lucia Wetland Park, and are afforded a degree of protection, but the same is not true for their foraging and dispersal ranges, and this is a cause for concern. Considerable amounts of data have been collected relating to the status, distribution and breeding efforts of these two species in north eastern KwaZulu-Natal. These data have been collected in a variety of ways by a large number of people. Part of this work represents an attempt to collate and summarise these data to produce an estimation of the status, distribution and breeding success of these species, and to evaluate any trends in their demography. For this south eastern region of Africa I estimated the population for the Great White Pelican to range between 6000 and 9000 individuals, and the Pink-backed Pelican to range between 600 and 900 individuals. Pelicans are highly mobile birds, and this allows them to move considerable distances when they forage, disperse or migrate. They are also long-lived birds with few natural predators. The two pelican species in south eastern Africa have been poorly studied and little is known about their movements, population dynamics and causes of mortality. Habitat change poses a potential threat to pelicans in north eastern KwaZulu-Natal, and habitat loss could drive these species out this region to areas north of South Africa. Much of this north eastern region of KwaZulu-Natal is under threat, mainly through the actions of man. Many areas are naturally unsuitable for pelican foraging, while others are vital to the survival of both species. This study includes an attempt to assess the movements of these two species in south eastern Africa, and to assess the relative importance and condition of the potential pelican habitat in the north eastern KwaZulu-Natal region, focusing particularly on Lake St Lucia and the Pongolo River floodplain. All this is necessary to produce a baseline from which long term predictions of potential pelican species survival can be made. In the absence of documented life tables and environmental variability data, a range of parameters was modelled to generate population viability analyses to simulate possible scenarios. These extinction models show the outcomes of both the deterministic and the stochastic processes. An attempt was also made to identify the factors that impact most severely on the persistence of these two species. The models were most sensitive to variation in survivorship in the first year of life and to the frequency of catastrophes. Changes in these parameters had the greatest effect on extinction risk. In January 2004 Lake St Lucia was reduced to a fraction of its normal capacity as a result of a severe drought in this region of KwaZulu-Natal. After rains in the area the lake level rose and then fluctuated considerably over the next 24 months. During this time the mouth of the estuary into the sea was closed. Great White Pelican numbers and lake levels were monitored throughout this period. This part of the study relates the changes in population numbers to the lake conditions, and highlights the importance of the lake to this avian species. It uses lake levels as a proxy for the conditions of wetlands in the Lake St Lucia region. It also addresses the implications of these relationships to the management strategy of the lake and the conservation of some avifauna. To identify conservation concerns for the Great White and Pink-backed Pelicans it was necessary to generate these baseline estimations. Although much of this information is uncertain for these two species, an attempt has been made here to predict the persistence of these species in north eastern KwaZulu-Natal and to highlight the conservation issues related to their future. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006
