- Description: African elephants (Loxodonta africana) were absent from large portions of the Eastern Cape Province of South Africa for more than 100 years following widespread hunting for ivory. However, recent shifts in land use practices have resulted in the establishment of many private game reserves throughout the region. Some of these reserves have reintroduced elephants, raising management concerns because of the perceived impact that elephants can have on vegetation and the animals that rely on it for resources. My thesis aimed to assess the role of elephants in determining the structure and complexity of the locally important Thicket Biome and how medium and large mammals are affected. I quantified the woody and succulent components of Albany Thicket across nine reserves with elephants between May 2016 and November 2017 using a modified Point-Centre-Quarter method. Camera traps were deployed at each site for the duration of a calendar year to measure the relative abundances of all medium and large mammals at the sites. Across all study sites, climatic conditions (specifically rainfall and temperature) were the primary drivers of woody vegetation structure and diversity. Elephants appeared to have little influence since they were reintroduced at low densities 20 years ago. The associated mammal communities were mostly influenced by the height and basal area coverage of the thicket across the sites. I conclude that because elephant populations have been maintained at relatively low densities across my study sites, negative effects on the thicket vegetation and the associated mammal communities were not observed. In fact, the establishment of private game reserves, even with elephants, present may offer sustainable conservation for the threatened Albany Thicket. However, these elephant populations are still relatively new and changes to the vegetation are likely to be cumulative. Thus, future research should focus on how the vegetation is affected over time. To this end, I recommend the establishment of permanent sampling stations across all reserves with elephants in the Eastern Cape Province.

The meaning of community: the viability of Public Sphere theory and Social Cohesion on social media groups: a reception study of the ‘Grahamstown’ Facebook Group

- Description: This study explores the meaning of community to Grahamstown’s online social media community, through a case study of the ‘Grahamstown’ Facebook group (GFG). The study explores the possibilities of social media as a public sphere and the way geographically-based social media sites might contribute to social cohesion in a community. The study explores what kinds of discussions take place on the GFG and why they are happening. It investigates whether these discussions can promote understanding and social solidarity, and whether useful deliberations are taking place, in some kind of approximation of a public sphere. Is this Group contributing to the wellbeing of the community, and how? Drawing on public sphere theory and various conceptions of the concept of social cohesion, the dissertation aims to find out how much of an impact the GFG has on Grahamstown/Makhanda inhabitants’ lives and sense of community. The study argues that with the advent of digital media, another ‘structural transformation’ in Habermasian terms, is underway, both empirically and theoretically. Through more than a dozen in-depth interviews combined with content analysis (via participant observation), the study finds that participation in and exposure to the GFG does lead, for many, to a sense of belonging and social cohesion as community members come together to act in relation to the state, local business and other institutions. The viability of ideas of highly localised (in time and space) ‘public sphericules’ as an alternative to broader more overarching concepts of a public sphere, is explored in this study. The study also suggests a typology of users, identifying the frequency, tone of voice and motives for participating on the GFG and attempts a periodisation of the GFG’s changing role in the community over the past decade.
