1. Piers, Laetitia. Implications of potential biome boundary shifts for small mammal assemblages in the arid zone .

Degree: 2019, University of the Western Cape

Desertification deteriorates the landscape functionality of rangelands, affecting the resilience of biome boundaries which have a cascade effect not only in vegetation composition and characteristics but also in animal communities. The balance between plants and small mammals are essential in maintaining the functionality (i.e. nutrient cycling, soil stability, and water infiltration) of rangeland which includes the arid Steinkopf communal rangeland. However, the landscape functionality of rangelands has not been extensively studied, especially in communal areas where desertification is a serious concern since many people farm with livestock to survive. The aim of this study was to assess landscape functionality along an arid biome boundary and its relationship to small mammal assemblages. This study further aimed to provide a local landscape perspective of the current desertification process and projected expansion of the Desert Biome into more mesic biomes in South Africa. Three replicates for three Desert Biome, ecotone and Succulent Karoo Biome sites (27 sites in total) were selected to assess landscape functionality and survey small mammal assemblages over a one-year period. The change in landscape functionality between the three areas was assessed to determine the resilience of the biome boundary to desertification. For each small mammal survey, 216 live Sherman traps were set up during the summer and winter seasons to account for breeding, mortality, and possible migration. With the data, the body condition index, population density, and diversity were quantified. Advisors/Committee Members: Engelbrecht, Adriaan (advisor).

2. Lamprecht, Adriaan Johannes Hendrikus. A vegetation study on the area leased for mining purposes by Impala Platinum, Rustenburg South Africa / Adriaan Johannes Hendrikus Lamprecht .

Degree: 2010, North-West University

Conservation and management of the ecology of natural areas has become a prerequisite for mining companies in South Africa. Systematic conservation planning provides a useful tool for land–use planning and impact assessment, particularly in the mining industry. A study was therefore undertaken to provide sufficient, spatially explicit biodiversity and veld condition information to aid in the development and establishment of an official conservation plan for the leased mining area of Impala Platinum. By identifying areas with high plant diversity or endemism and by assessing veld conditions as well as grazing and browsing capacities, recommendations could be made towards management strategies and potential future land–use practices. The licensed mining area, north of Rustenburg, covers 29334 ha and includes 14 operational shafts. The area was stratified into three main categories based on landscape types namely: norite koppies; thornveld and rehabilitated areas. The Braun Blanquet approach was followed to sample 139 stratified random relevés. Additional computer software packages were used for capturing, processing and presentation of the phytosociological data (TURBOVEG) as well as a visual editor for phytosociological tables (MEGATAB). Ordinations were subsequently performed to confirm the plant communities and illustrate possible environmental gradients, using multivariate statistic analyses (CANOCO). Four plant communities with two subcommunities were identified and described in both the norite koppies and thornveld respectively while three plant communities with three sub–communities were identified in the rehabilitated areas. Specific environmental factors that influence plant community structure and composition in the norite koppies were the aspect and percentage of soil surface rockiness while soil types proved to be the distinguishing factor in the thornveld. The distribution of plant communities in the rehabilitated areas is mainly due to anthropogenic influences rather than any environmental factors. The Fixed Point Monitoring of Vegetation Methodology– FIXMOVE was then used to sample 32 stratified random survey plots in four selected plant communities in order to quantify and compare veld conditions as well as grazing and browsing capacities. The determination of landscape functionality served to support these quantitative results. The Landscape Function Analysis (LFA) method was used for this purpose. Multivariate statistic analyses (CANOCO) were used to indicate possible degradation gradients between the plant communities. Conclusions regarding conservation and management units were reached by interpreting the quantitative data in accordance with the phytosociological results and recommendations could then be made. All the norite koppies plant communities were recommended as areas for The Fixed Point Monitoring of Vegetation Methodology– FIXMOVE was then used to sample 32 stratified random survey plots in four selected plant communities in order to quantify and compare veld conditions as well as grazing…
