Studying the decisions that an individual animal makes across different levels of selection, from its choice in dietary item to predator avoidance strategies, is a fundamental link in understanding the response of groups of animals and ultimately entire populations that may provide insight into population performance. The study formed part of a broader study focused on the decline of rare antelope species. Specifically this study was aimed at establishing the home range and resource use of sable antelope in a region where they were initially expected to be thriving. The levels of selection covered in this study are: the location of home ranges of an individual or social group within the landscape; the use of various habitat components within the home range; and the procurement of food items within those habitats. At the highest level, the broad objectives were (1) to determine where sable occupied home ranges within the landscape, indicating the suitability of various landscape units to sustain sable populations and (2) to determine the relative use of habitat types within those home ranges that may enable sable to avoid predation and acquire resources required to survive and reproduce. At the lowest level of selection the characteristics of forage selection and how the grass quality in the different vegetation types during different seasons affects the success of sable herds was explored. The broad objectives were (1) to determine the effect of seasonal flooding and rainfall on grass greenness in the floodplains and upland vegetation types and the consequent use of those vegetation types by sable antelope and (2) to determine how exploitation of resources in the floodplains and in the uplands contributed to the nutritional status of sable. I additionally quantified the time spent browsing and determined the composition of the browse component of the diet of sable. Adult female sable from each of three adjacent sable herds were fitted with GPS collars providing hourly GPS co-ordinates. Adaptive LoCoH was used to determine home range location and annual, seasonal and core home range extents. A vegetation map was created and the number of GPS locations within each vegetation type was counted to determine their relative use in relation to availability within the home ranges. GPS collars were used to locate herds daily so that foraging observations of browsing and characteristics of the grasses grazed could be attained. Acceptability and dietary contributions of grass species and browse were determined for each sable herd during different seasons. The availability of grass species on the floodplain grasslands and in the upland grasslands and woodlands was estimated. Water and the availability of key resources posed a constraint on where sable home ranges were established. Sable simply did not occupy the region in the north of the study area further than 7 km from permanent water and floodplain grasslands. Herds generally avoided open savanna, mopane woodlands and Kalahari apple-leaf woodlands characterised by sparse grass cover, particularly during the dry season. Home ranges were relatively small compared 4 to the range estimates from herds in Kruger National Park. There was no obvious seasonal difference in home range extent nor were there large areas of overlap between home ranges of adjacent herds. Observations during the study indicated that competitor species, including zebra and wildebeest, concentrated on the floodplain grasslands. Throughout the year H. dissoluta was the most strongly favoured grass species and contributed most to the diet of the sable herds in both the wet and dry season. During the dry season sable herds expanded their diet to include Aristida stipitata and Aristida meridionalis which are generally considered poor forage value species for cattle but that retained some greenness. Additionally, the contribution of browse, especially the leaves of Croton megalobotrys, Philenoptera nelsii and Combretum mossambicense and the flowers of Kigelia africana, constituted an important bridging resource during the extended dry season. Crude faecal protein levels remained above the suggested maintenance levels throughout the annual cycle. Crude faecal protein levels were elevated prior to calving when sable spent more time foraging on the floodplain grasslands where high value forage species such as Paspalum scrobiculatum, Panicum repens and Urochloa mossambicense and sedges were eaten. Indications are that the constraint posed by the distribution of water within the landscape, rather than resource limitations within occupied home ranges, are the primary limitation to population performance in the Kwedi concession. / Wilderness Safari, the Wilderness Wildlife Trust, the Conservation Foundation, Classic Africa and National Research Foundation (NRF) of South Africa.

Abstract in English, Afrikaans and Zulu / Tourism generates foreign currency and employment, and proper planning and management benefits the community and environment upon which tourism depends. The study investigated the management of sustainable action plans at selected nature-based attractions in Botswana, namely; Gaborone Game Reserve, Khutse Game Reserves, and Mokolodi Nature Reserve. Purposive, convenience and snowball sampling yielded 25 respondents for semi-structured interviews. Findings highlighted that sustainable action plans, like recycling and engaging local labour, were managed and implemented to a small extent. The conclusions were that the full potential of sustainable action plans management needed to be fully explored. The study recommends government enforcement of policies, master plans and strategies for management of sustainable action plans in nature-based attractions; and decentralisation of public nature-based attractions to allow managers full management of sustainable action plans. Government and private sector should fund management of all nine sustainable action plans, and implement a holistic tourism strategy to retain the quality of tourists’ experiences. / Ezokuvakasha zidala imali yangaphandle kanye nomsebenzi, nokuhlelwa kahle nokuphathwa kahle komphakathi kanye nemvelo lapho ezokuvakasha zincike khona. Ucwaningo lucwaninge ukuphathwa kwezinhlelo zokusebenza ezisimeme ezikhethiwe zokukhangiswa kwemvelo eBotswana, okuyiSiqiwi iGaborone, iSiqiwi iKhutse, nokuGcinwa kweMvelo iMokolodi. Imibonakaliso ekhethwe ngokusekelwe ezilinganisweni zabantu kanye nenhloso yocwaningo (purposive sampling), indlela yokubala nokudweba idatha emele ngokukhetha abantu ngenxa yokukhululeka kokuzithandela kwabo (convenience sampling) kanye nabacwaningi bezokucwaninga abathatha abanye abahlanganyeli ukuze banze ucwaningo (snowball sampling) inikeza abaphenduli abangu-25 ngemibuzo ehleliwe. Okutholakele kubonise ukuthi izinhlelo zokusebenza ezisimeme, njengokuvuselela kabusha nokubandakanya abasebenzi basekhaya, zaphathwa futhi zenziwa ngendlela encane. Isiphetho sasiwukuthi amandla aphelele okuphathwa ezinhlelo zokusebenza ezisimeme kufanele ahlolwe. Ucwaningo luphakamisa ukuqiniswa kwezinqubomgomo kuhulumeni, izinhlelo ezinhle kanye namasu okuphathwa kwezinhlelo zokusebenza ezisimeme ezikhethiwe zokukhangiswa kwemvelo; kanye nokwabiwa kwamandla okukhangayo okusekelwe emphakathini ukuvumela abaphathi ukuphatha ngokugcwele kwalezi zinhlelo. Uhulumeni kanye nezimboni ezizimele kufanele baxhase ukuphathwa kwazo zonke izinhlelo zokusebenza ezisimeme eziyisishiyagalolunye, futhi basebenzise uhlelo lwezokuvakasha oluphelele ukugcina isipiliyoni sabavakashi sisezingeni. / Toerisme genereer buitelandse valuta en werkverskaffing, en behoorlike beplanning en bestuur is tot voordeel van die gemeenskap en omgewing waarop toerisme staatmaak. Die studie het die bestuur van volhoubare aksieplanne by geselekteerde natuurgebaseerde besienswaardighede in Botswana, naamlik die Gaborone, Khutse en Mokolodi Natuurreservate, ondersoek. Doelbewuste, gerief- en sneeubalsteekproefneming het 25 respondente vir semigestruktureerde onderhoude opgelewer. Volgens die bevindings, is volhoubare aksieplanne soos herwinning en die gebruik van plaaslike arbeid, tot ’n mate bestuur en geïmplementeer. Die gevolgtrekking was dat die volle potensiaal van volhoubare aksieplanbestuur verken moet word. Die studie het regeringstoepassing van beleide, meesterplanne en strategieë aanbeveel vir die bestuur van volhoubare aksieplanne in natuurgebaseerde besienswaardighede; en die desentralisasie van openbare natuurgebaseerde besienswaardighede om bestuurders toe te laat om hierdie planne ten volle te bestuur. Die regering en die privaat sektor behoort die bestuur van al nege die volhoubare aksieplanne te befonds, en 'n holistiese toerismestrategie te implementeer om die gehalte van toeriste-ervarings te behou. / Transport Economics, Logistics and Tourism / M.
