This thesis investigates the design of a model, methods and guidelines that may assist government agencies in South Africa to find a balance between the objective of biodiversity conservation and increased local economic development in cases of land restitution in protected areas. The data collection that was needed for this study took place from 2007 to 2009 and was limited to seven priority protected areas in Mpumalanga Province. The general model design was established via an extensive literature review and analysis of the legal background and formed the theoretical concept of this thesis. The general model design was used to devise the guidelines for co-management to be used by government agencies in South Africa for the possible implementation of the biodiversity conservation and local economic development mandates in cases of land restitution in protected areas, within their financial and institutional limitations. From the results, it is clear that a consolidated government position, agreed upon by all relevant government stakeholders, assists in keeping the land restitution process in protected areas within the legal framework. Through the analysis of the model design in the seven priority protected areas it was identified that additional information is needed to reach the preferred land claim settlement option per protected area such as the actual tourism record, a socio-economic assessment of the environment in which each protected area is embedded, and financial figures to make projections on current and future net profit calculations. Government should support all the land claim settlement options, as elaborated in the model design, which is not the case at the moment, and most alternative options, other than co-management, are currently still unclear and/or not feasible. This might have serious negative implications for the conservation agency, with the risk of compromising its mandate to manage areas of high biodiversity effectively. The methods that were developed to workshop the generic agreement frameworks with the land claimant representatives proved to assist in the land claimants making an informed choice within the legal framework and to tailor the land claim settlement option and agreements to their specific situation. / Development Studies / Ph.

The uMkhuze Game Reserve in South Africa is a key biodiversity asset which protects diverse natural resources of regional, national and international importance. The park has a notorious history of poaching, which is considered to be the second most important threat to biodiversity. Paramilitary patrol operations are crucial to regulating poaching in the park, and to the collection of data important for the monitoring of the state of biodiversity. The effectiveness of the patrol system as a whole is gauged primarily from enforcement-related data, and it was the intention of this study to present a landscape level perspective that would bolster current evaluation metrics. Home range and use-availability analyses of patrol data collected in 2009 and 2010 were used to construct area coverage boundaries, and to understand whether the distribution of patrol effort within patrol areas was influenced by habitat type. Results suggest that average monthly patrol area coverage ranged from 8.38 km² to 23.15 km². This indicates that although designated patrol areas could be covered with relative ease within a few months, information gaps were consistently occurring in the system. To determine how differences in the amount of area covered by patrol units influenced the quantity of information collected, annual area coverage was correlated with the number of biological sightings, illegal incidents and snares reported. Results show that differences in the size of the area covered did not necessarily influence the quantity of information collected in the field. However, certain areas of the park remained unpatrolled annually. All patrol units visited habitats differently than expected based on the proportion of habitat types that were available to them. The preferential use of habitat types could result in incorrect inferences being made about information outputs generated by the patrol system. The number of biological sightings, illegal incidences and snares reported were associated with the total area of each habitat emphasizing the importance of covering habitats proportionately to their availability in the park. / Thesis (M.Env.Dev)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Thesis (MScConEcol)--UnStellenbosch University, 2011. / ENGLISH ABSTRACT: The privilege of utilising resources from the globe's marine ecosystems is threatened. Adequate regional and global conservation efforts are vital. Understanding species' distributions and the environmental variables influencing community structures are important for instigating optimum conservation plans. A major threat facing marine ecosystems is the introduction and proliferation of alien invasive species. The distribution and geographical expansion of marine alien invasive species, along with environmental variables driving their increase is also critical for drawing up conservation plans. In response to this point, this study addresses gaps in our knowledge regarding intertidal marine invertebrate species distributions particularly that of marine alien species in the Kogelberg Biosphere Reserve (KBR) and adjacent Betty's Bay Marine Protected Area (MPA) in the Western Cape of South Africa, a prime area for south-coast marine conservation. Species identifications were done in September 2010. Two marine alien invertebrate species were identified along the coastline. These were the invasive mytilid Mediterranean mussel Mytilus galloprovincialis and the bryozoan Watersipora subtorquata. A quantitative systematic survey of the intertidal region, consisting of seven rocky shore sites was then undertaken from October 2010 to December 2010. The abundance of all focal marine invertebrate species, within six selected habitat types was assessed. Environmental variables were also recorded. Statistical tests were done to investigate for significant interaction in mean abundance and mean species richness among intertidal zones and protection status (MPA and non-MPA), and among intertidal sampling units (SU‟s) and protection status. There was also investigated for significant difference in mean abundance and mean species richness across intertidal zones and habitat types where protection status was not taken into account, and to test for significant differences in mean abundance and mean species richness between the intertidal zones and habitat types. Correspondence analyses were used to illustrate relationships between species composition and the defined environmental variables. Tests were done to investigate for significant differences in mean abundance of the identified marine alien species between the MPA and non-MPA, study sites, SU's, and wave exposures. These results indicated that vertical and horizontal stress gradients along the shore mainly influence abundance and species richness. The significantly higher abundance of M. galloprovincialis outside the MPA is due to its preference for wave-exposed areas. The reason for the difference in the total abundance of W. subtorquata in the different habitats is not clear, although it appears that the higher abundance of this species in the MPA is because the sheltered nature of the MPA. M. galloprovincilais displaces indigenous species. W. subtorquata does not cause any significant harm along the coast of South Africa. This study indicates that the abundance of M. galloprovincialis and W. subtorquata in the MPA is relatively low. The MPA is therefore in good condition with regards to intertidal alien species. It is important that the MPA and adjacent KBR's coastline maintain its current pristine status. / AFRIKAANSE OPSOMMING: Die voorreg om mariene hulpbronne te benut, word bedreig. Voldoende nasionale en globale mariene bewaring is krities. 'n Deeglike kennis van spesies verspreiding en omgewingsveranderlikes wat gemeenskapstrukture beïnvloed is noodsaaklik vir optimale bewaringspogings. Mariene indringerspesies en verspreiding van indringerspesies bedreig mariene ekosisteme. Dit is belangrik om basiese kennis in te win oor die geografiese verspreiding van indringerspesies saam met die omgewingsveranderlikes wat hierdie verspreiding beïnvloed. Hierdie studie fokus dus daarop om die kennis met betrekking tot intergety ongewerwelde spesiesverspreiding, veral dié wat uitheems is langs die kus van die Kogelberg Biosfeer Reservaat (KBR) en aangrensende Bettys Baai Mariene Beskermde Gebied (MBG) in die Wes-Kaap in Suid-Afrika uit te brei. Hierdie streek word beskou as gesog vir mariene bewaring in Suid-Afrika. Identifikasie van spesies is in September 2010 gedoen. Twee intergety uitheemse ongewerwelde spesies is langs die kus geïdentifiseer; die indringer 'mytilid' Mediterreense mossel - Mytilus galloprovincialis en die 'bryozoa' Watersipora subtorquata. 'n Kwantitatiewe sistematiese oorsig van die intergety rotsagtige streek, bestaande uit sewe lokaliteite, is gedoen. Steekproefneming is vanaf Oktober 2010 tot Desember 2010 uitgevoer. Alle fokale intergety ongewerwelde spesies, in ses geselekteerde habitattipes is getel. Omgewingsveranderlikes is aangeteken. Daar is statisties getoets vir verskille in die talrykheid en spesiesrykheid tussen die intergety zones en beskermingsstatus (MBG en nie-MBG), en tussen die intergety habitattipes en beskermingsstatus. Daar is ook getoets vir verskille in talrykheid en spesiesrykheid tussen die intergety zones en habitattipes waar beskermingsstatus nie in ag geneem is nie. Ooreenstemmende analises is gedoen om die verhoudings tussen die spesiesamestelling en die gedefinieerde omgewingsveranderlikes te illustreer. Daar is statisties getoets vir verskille in die talrykheid van die geïdentifiseerde uitheemse spesies tussen die MBG en nie-MBG, die verskillende lokaliteite, die verskillende habitattipes en tussen die verskillende golf blootstellings. Hierdie studie dui aan dat vertikale en horisontale stresgradiënte die hoofoorsaak is wat talrykheid en spesiesrykheid beïnvloed. Die aansienlik hoër talrykheid van M. galloprovincialis buite die MBG is van die gebied se hoër golfblootstelling. Die beduidende verskil in talrykheid van W. subtorquata is onduidelik. Dit kan egter afgelei word dat die beskutte aard van die MBG 'n rol speel by die aansienlik hoër talrykheid van hierdie spesie binne die MBG. M. galloprovicialis verplaas inheemse spesies. Geen beskikbare bewys dui daarop dat W. subtorquata enige beduidende skade langs die kus van Suid-Afrika aanrig nie. Die lae talrykheid van beide hierdie spesies binne die MBG dui daarop dat hierdie unieke area steeds in goeie toestand ten opsigte van intergety uitheemse spesies is. Dit is noodsaaklik dat die huidige status van die MBG en aangrensende kuslyn gehandhaaf word.
