- Description: This paper attempts to address the issue of hardening the internal secu-rity of an organisation’s network by easing its patch management. Tradi-tionally security has been modeled on a" hard outer shell" approach, with a firewall protecting the otherwise vulnerable internal network. With the advent of worms using such techniques as social engineering to by-pass the organisational firewall and installing trojans, this approach is no longer sufficient. As a result of these new attacks, emphasis should be placed on improving the security of the internal network. Most research agrees that prompt patching of security vulnerabilities would significantly reduce the vulnerability of these machines. However, this requires sys-tem administrators not only to keep abreast of the flood of patches, but to ensure they are deployed to every machine, in what could be a very large network. These difficulties are worsened by problems the patches themselves often create. This is a difficult task and the failure of system administrators to perform it is echoed in the recent spate of worm at-tacks, with some taking advantage of vulnerabilities for which patches had been released up to six months earlier.

- Description: We briefly review the taxonomic history of the Podocarpaceae, with an emphasis on the recognition of numerous segregate genera out of Podocarpus sensu lato. Despite some controversy over the recognition of these genera, molecular data (DNA sequences) provide evidence that supports this taxonomy. The implications for African Podocarpaceae are discussed. In particular, molecular data support the recognition of Afrocarpus as distinct from Podocarpus. Additional taxonomic problems concerning the possible segregation of Podocarpus milanjianus from P. latifolius are addressed using DNA sequence data from the nuclear internal transcribed spacer 2 (ITS2) region. Results of this are inconclusive, and suggest that alternative DNA-based evidence, such as from AFLPs or microsatellites, may be more informative in resolving such species complexes in African Podocarpus.

- Description: Abortion is a highly controversial subject that has again come into the spotlight in South Africa due to the legalisation of abortion on demand in 1996. The results of various studies conducted since the Choice on Termination of Pregnancy Act 92 of 1996 was implemented, have indicated that abortion providers have met with a great deal of negativism and ostracism. This study focused on the implications of abortion work on nurses' social relationships with family, friends, colleagues and their communities. Recent literature was reviewed on the subject. The researcher however, found little information on this specific aspect of abortion. The study was conducted with abortion nurses from two government designated hospitals in the East London area responsible for abortion services. Thus, results cannot be generalised. This is a qualitative study that aimed at obtaining firsthand information regarding the personal experiences of abortion nurses. A non-probability sampling technique was used viz. criterion sampling. The Interview Guide Approach was used whereby in-depth, semi-structured interviewed were conducted with the guidance of a set of questions in the form of an Interview Schedule. The ten respondents were asked to share their recommendations as to possible measures that could address the challenges mentioned during their interviews. The researcher came to the conclusion that nurses' social relationships and lives are definitely impacted by abortion work. This impact is largely negative as the majority of respondents experience labelling, stigmatization and ostracism from family, friends, and their colleagues. Abortion nurses also experience a lack of social support, ambivalent feelings with regard to abortion, and a range of negative emotions ranging from stress and depression to frustration and anger. A number of repeat abortions are being done and there seems to be a general lack of contraception. The need exists for nurses to go to Value Clarification Workshops and also to get support in terms of compulsory, continuous, counselling. Separate wards should be set up for abortions whilst sex education should be included in school curriculums at both primary and secondary schools. Family planning and facts about the abortion process should also be included in these sex education programmes. Overall. the need exists for family planning initiatives to promote contraception and deter women from using abortion as a means of contraception. As this study reveals, conducting abortions has come at a great cost for the majority of nurses who lack social support and bear the brunt of anti-abortion sentiment expressed by significant others in their lives. The latter being the people who would normally be the one's they would turn to for help, counsel, support and assistance

- Description: The article focuses on active anting in captive Cape white-eyes Zosterops pallidus. In this study, observation of captive birds at close quarters enables to test some of the stimuli that could elicit this behavior. When anting, birds either brush ants through their plumage or allow ants to crawl over them. Anting has been recorded in more than 160 species of passerine birds worldwide. Nevertheless, it is rarely observed in the wild, perhaps because the actions resemble preening movements or dust-bathing. Experiments were designed to clarify whether white-eyes ant before eating ants, and whether anting is correlated with moult in this species.

- Description: A southern race of the Olive Thrush, Turdus olivaceus smithi Bonaparte, has recently been proposed as a full species, the Karoo Thrush Turdus smithi (Bowie et al. 2003). Some of the published information on the Olive Thrush Turdus olivaceus olivaceus thus pertains to the Karoo Thrush (eg Kopij 2000), whereas other information deals specifically with the Olive Thrush (eg Winterbottom 1966, Bonnevie et al. 2003). We have ringed, recaptured and recovered both Olive and Karoo Thrushes in the Eastern Cape since 1986, and the two taxa are markedly different in this region. We describe some differences in appearance of the two populations from these data, and compare mass and wing length of living birds, as well as culmen and tarsus lengths of museum specimens from the East London Museum, South Africa. The collection sites of the museum specimens were mapped using ArcView 3.1 (ESRI 1996) together with the ringing sites (Figure 1). Areas of potential sympatry are Oudtshoorn (33 25’S, 22 11’E) and Patensie (33 45’S, 24 48’E).

- Description: The term affirmative action originated in the United States some 30 years ago to describe a process of liberating minority groups. The objective of affirmative action within an organisational context, is to democratise the workplace by enabling members of previously disadvantaged groups to progress higher up the ranks of the corporate world. The affirmative action drive only took off in South Africa when it became part of the democratisation process and the focus was directed towards liberating the historically disadvantaged black majority. Prior to 1994, the reasons for implementing affirmative action programmes were largely political because of the race-based discrimination. Historically disadvantaged people were a minority in senior positions, the reason being that although the blacks were given a chance to compete with their white counterparts, due to their poor education standards and lack of experience only a few was appointed. The Employment Equity Act 55 of 1998 aims to correct the demographic imbalances in the nation’s workforce by compelling employers to remove barriers to advancement of blacks, coloureds, Indians, women and disabled, and actively to advance them in all categories of employment by affirmative action. The Employment Equity Act consists of two main sections. The first replaces and refines the prohibition on unfair discrimination in item 2(1)(a) of Schedule 7 of the Labour Relations Act. The second aspect deals with imposing a duty to the employers to adopt affirmative action programmes. The Employment Equity Act places a positive obligation on all employers “to promote equal opportunity in the workplace by eliminating unfair discrimination in any employment policy or practice”. Where unfair discrimination is alleged, the onus of proving that discrimination is fair, or practice is not discriminatory at all, rests upon the employer. Disputes about unfair discrimination must be referred to the CCMA, and if not settled by conciliation, to the Labour Court, which has the power to order compensation or the payment iv of damages, or to direct the employer to take steps to prevent the same unfair discrimination or similar practice occurring in the future in respect of other employees. The second section of the Employment Equity Act deals with the imposition of the duty to designated employers to adopt affirmative action programmes. All employers with more than 50 employees, or which have annual turnovers equal to or above the annual turnovers for small businesses of their class, municipalities, organs of state, and those designated as such by collective agreement, must implement affirmative action measures for people from designated groups. This entails consulting with employers, conducting an analysis of employment policies, practices, procedures and the working environment to identify barriers, drawing up employment equity plans and reporting thereafter to the Director-General of the Department of Labour on progress made in implementing the plan. Any employee may bring alleged contraventions of the Act to the attention of the employer, another employee, or any trade union, workplace forum, labour inspector or the Director- General of the Employment Equity Commission. Labour inspectors appointed under the Basic Conditions of Employment Act may enter and inspect employer’s properties and documents, and are responsible for ensuring that the employer has consulted with employees as required, conducted the pre-equity plan analysis prepared its plan and is implementing it, submitted and published its reports, set up the necessary managerial infrastructure, and informed its employees of progress. Should employers be found not to have complied with these requirements, labour inspectors must request a written undertaking that they will do so. If an employer fails to give such an undertaking, the labour inspector can issue a compliance order setting out inter alia what steps the employer must take and when, and the maximum fine, if any, that can be imposed if the employer fails to comply. If the employer does not pay attention to the compliance order within the prescribed period, the Director-General may apply to have it made an order of the Labour Court. The Director-General may also conduct independent ad hoc reviews of selected designated employers. Failure by an employer to comply with the provision of the Act lead to the employer being liable for the contravention of the Act.

- Description: Diplotaxodon limnothrissa Turner (1995) is a widely distributed species occurring throughout Lake Malawi, extending from the surface to a depth of at least 220m. It is probably the most abundant cichlid in the lake with biomass estimates of around 87 000 tonnes in the pelagic zone alone. The species is exploited commercially in the southern part of the lake but since its inception the fishery has never been assessed. As such this study investigates some aspects of age and growth of the species besides applying a yield-per-recruit analysis to assess the status of the fishery. Analysis of sectioned sagittal otoliths revealed that D. limnothrissa is fast growing and relatively long-lived species, attaining ages in excess of 10 years. Growth in length was rapid in immature fish, with fish attaining almost half of their maximum size within their first year. Le ngth-at-age was described by the von Bertalanffy growth model with combined-sex growth described as Lt = 211.21(1-exp(- 0.24(t+1.36))) mm TL. Total, natural and fishing mortalities were estimated at 0.76 yr⁻¹, 0.31 yr⁻¹ and 0.45 yr⁻¹ respectively. Per-recruit analysis indicated that the D. limnothrissa stock in the southeast arm of the lake is fully exploited as indicated by the current spawner biomass-per-recruit ratios of 31-55% (SB/R)F=0. Modelling indicated that the current age-at-capture (2.67 years) is lower than the age at which yield is optimised (> 5 years) based on the F₀·₁ harvesting strategy. It is, therefore, recommended that the age-at-capture should be increased from 2.67 to 5 years to optimise yield.

- Description: Diplotaxodon limnothrissa Turner (1995) is a widely distributed species occurring throughout Lake Malawi, extending from the surface to a depth of at least 220m. It is probably the most abundant cichlid in the lake with biomass estimates of around 87 000 tonnes in the pelagic zone alone. The species is exploited commercially in the southern part of the lake but since its inception the fishery has never been assessed. As such this study investigates some aspects of age and growth of the species besides applying a yield-per-recruit analysis to assess the status of the fishery. Analysis of sectioned sagittal otoliths revealed that D. limnothrissa is fast growing and relatively long-lived species, attaining ages in excess of 10 years. Growth in length was rapid in immature fish, with fish attaining almost half of their maximum size within their first year. Le ngth-at-age was described by the von Bertalanffy growth model with combined-sex growth described as Lt = 211.21(1-exp(- 0.24(t+1.36))) mm TL. Total, natural and fishing mortalities were estimated at 0.76 yr⁻¹, 0.31 yr⁻¹ and 0.45 yr⁻¹ respectively. Per-recruit analysis indicated that the D. limnothrissa stock in the southeast arm of the lake is fully exploited as indicated by the current spawner biomass-per-recruit ratios of 31-55% (SB/R)F=0. Modelling indicated that the current age-at-capture (2.67 years) is lower than the age at which yield is optimised (> 5 years) based on the F₀·₁ harvesting strategy. It is, therefore, recommended that the age-at-capture should be increased from 2.67 to 5 years to optimise yield.

- Description: The purpose of this dissertation was to provide a review of the theory of Optimization, in particular quadratic programming, and the algorithms suitable for solving both convex and non-convex quadratic programming problems. Optimization problems arise in a wide variety of fields and many can be effectively modeled with linear equations. However, there are problems for which linear models are not sufficient thus creating a need for non-linear systems. This dissertation includes a literature study of the formal theory necessary for understanding optimization and an investigation of the algorithms available for solving a special class of the non-linear programming problem, namely the quadratic programming problem. It was not the intention of this dissertation to discuss all possible algorithms for solving the quadratic programming problem, therefore certain algorithms for convex and non-convex quadratic programming problems were selected for a detailed discussion in the dissertation. Some of the algorithms were selected arbitrarily, because limited information was available comparing the efficiency of the various algorithms. Algorithms available for solving general non-linear programming problems were also included and briefly discussed as they can be used to solve quadratic programming problems. A number of algorithms were then selected for evaluation, depending on the frequency of use in practice and the availability of software implementing these algorithms. The evaluation included a theoretical and quantitative comparison of the algorithms. The quantitative results were analyzed and discussed and it was shown that the results supported the theoretical comparison. It was also shown that it is difficult to conclude that one algorithm is better than another as the efficiency of an algorithm greatly depends on the size of the problem, the complexity of an algorithm and many other implementation issues. Optimization problems arise continuously in a wide range of fields and thus create the need for effective methods of solving them. This dissertation provides the fundamental theory necessary for the understanding of optimization problems, with particular reference to quadratic programming problems and the algorithms that solve such problems. Keywords: Quadratic Programming, Quadratic Programming Algorithms, Optimization, Non-linear Programming, Convex, Non-convex.

- Description: This paper describes an analysis of automatically scaled F1 layer data over Grahamstown, South Africa (33.3°S, 26.5°E). An application for real time raytracing through the South African ionosphere was identified, and for this application real time evaluation of the electron density profile is essential. Raw real time virtual height data are provided by a Lowell Digisonde (DPS), which employs the automatic scaling software, ARTIST whose output includes the virtual-to-real height data conversion. Experience has shown that there are times when the raytracing performance is degraded because of difficulties surrounding the real time characterisation of the F1 region by ARTIST. The purpose of this investigation is to establish the extent of the problem, the times and conditions under which it occurs, with a view to formulating remedial alternative strategies, such as predictive modelling.

- Description: This study was evoked by a discussion with one of Dimension Data’s Service Management Executives. The discussion was centred around customer service management focus and on how to bring all stakeholders within the organisation to share this common goal. The critical aspect does not merely mean improving quality, but to exceed customers’ expectations according to Manning (1989:63). Quality and customer service have become a way of life rather than, short-term projects that can begin and end at will emphasises Manning (1989:91). There is a myriad of evidence to suggest that services are becoming critical to economic growth in most developing economies, one of such is South Africa. Thus South African industry requires substantial reflection both from the government and private sector regarding issues of service. Organisations therefore need to understand products and services as complex clusters of value adding satisfactions. The main problem of this research is as follows: What customer service management strategies are at the disposal of an information technology organisation? The main problem will be solved in the form of three sub-problems, by identifying what customer service management is. Secondly, depicting a customer service management model and lastly recognising customer service strategies that exist within Dimension Data.

- Description: An overview of the literature indicates that there is a real and pressing need to explore the concept of adverse impact in more detail. The Employment Equity Act of 1998 prioritises the issue of group representivity in staff selection and although there are merits in enforcing an Affirmative Action policy, an objective assessment of the inherent requirements of job applicants is still a constitutional and procedural outcome. There is no simple mechanism that can be used to determine the manifestation of adverse impact. However, evidence thereof can be most useful in securing fairness in selection and employment decisions. There is a distinct need to examine the matter of adverse impact and its implications in the South African context. South Africa is confronted with a labour force that is growing dramatically and changing significantly. The demographic trends in our dynamically changing labour markets are likely to amplify skill and ability differences between the resulting contradictory goals of equal opportunity based on individual merit and equal employment results for subgroups of populations. Three selection strategies of a communications company were used as a basis for the assessment of adverse impact. The total population of the Call Centre selection strategy was 150. Seven instruments and measures were utilised in the study, namely, a job analysis, pre-screening exercise, psychometric ability tests, role-play simulation, structured interview, job compatibility questionnaire and a performance evaluation. The total population of the Operator Services selection strategy was 139. Five psychometric instruments were utilised in the study. The total population of the Female Leadership Development Programme selection strategy was 471. Three psychometric instruments were utilised in the study. The Adverse Impact Model was applied to each of the aforementioned strategies. In terms of the definition, adverse impact exists if the selection ratio associated with a particular passing score on a test for one sub-group of job applicants is less than 4/5th’s or 80% of the selection ration for the largest sub-group of applicants. 13 The results of the study indicate that adverse impact occurred in the following instances. In the Call Centre selection strategy, there was evidence of adverse impact in the racial analysis in the ability testing stage. There was also evidence of adverse impact in the gender analysis during this stage. There was no evidence of adverse impact in either the racial or gender analyses during the interview stage. There was no evidence of adverse impact in the racial analysis during the appointment stage. There was however evidence of adverse impact in the gender analysis during the appointment stage. The Female Leadership Development Programme selection strategy revealed evidence of adverse impact in the racial analysis during the appointment stage. The Operator Services selection strategy revealed an adverse impact in both the racial and gender analyses during the testing stage. The issue of adverse impact is obviously controversial. However, data obtained from this process will provide for informative analysis.

- Description: Due to the continual increase in competitive pressure from international organisations, it has become necessary to assess the degree of transformational change within South African organisations to overcome the effect of global forces. Transformation was investigated in terms of organizational restructuring and the various work designs that are utilised by organisations to deal with the effect of global forces. To examine the main problem, three sub-problems were identified. The first sub-problem that had been identified dealt with the extent of which global forces impacted on the business environment. It was investigated by evaluating various economic, technological and sociopolitical forces. From the results it may be concluded that global forces have a large impact on the local business environment. The second sub-problem looked at the degree to which work designs assisted organisations to manage the effect of global forces. It was evident that the flexible types of work designs were more readily utilised to optimise productivity and employee moral. Finally, the third sub-problem investigated the various structures that organisations could adopt to deal with the effect of global forces. Organisational structures were analysed in terms of customer orientation, fulfilment of company objectives and the types of structures that are used within organisations. The results showed that 75% of the sample population believed that their organisational structures co-ordinated all activities within their organisations. Feedback on the type of structures that were used by organisations revealed that various types are being used.

- Description: The censorship of popular music in South Africa during the 1980s severely affected South African musicians. The apartheid government was directly involved in centralized state censorship by means of the Directorate of Publications, while the South African Broadcasting Corporation exercised government censorship at the level of airplay. Others who assisted state censorship included religious and cultural interest groups. State censorship in turn put pressure on record companies, musicians and others to practice self-censorship. Many musicians who overtly sang about taboo topics or who used controversial language subsequently experienced censorship in different forms, including police harassment. Musicians were also subject to anti-apartheid forms of censorship,such as the United Nations endorsed cultural boycott. Not all instances of censorship were overtly political, but they were always framed by, and took place within, a repressive legal-political system. This thesis found that despite the state's attempt to maintain its hegemony, musicians sought ways of overcoming censorship practices. It is argued that the ensuing struggle cannot be conceived of in simple binary terms. The works of Antonio Gramsci, Michel Foucault and Pierre Bourdieu, in particular, are applied to the South African context in exploring the localized nuances of the cultural struggle over music censorship. It is argued that fragmented resistance to censorship arose out of the very censorship structures that attempted to silence musicians. Textual analysis brought to light that resistance took various forms including songs with provocative lyrics and titles, and more subtle means of bypassing censorship, including the use of symbolism, camouflaged lyrics, satire and crossover performance. Musicians were faced with the challenge of bypassing censors yet nevertheless conveying their message to an audience. The most successful cases negotiated censorial practices while getting an apparent message across to a wide audience. Broader forms of resistance were also explored, including opposition through live performance, counter-hegemonic information on record covers, resistance from exile, alignment with political organizations and legal challenges to state censorship. In addition, some record companies developed strategies of resistance to censorship. The many innovative practices outlined in this thesis demonstrate that even in the context of constraint, resistance is possible. Despite censorship, South African musicians were able to express themselves through approaching their music in an innovative way.

- Description: The cable manufacturing industry may not be well known to some people, yet people’s very lives depend on products and services it produces. Today people live in a highly technological or digital world where most of the technology used by society has at least one electrical cable in it or is connected to a countrywide electrical or communications network through electrical cables in order to work. Well trained and experienced corporate and business leaders recognize the importance of lean supply chain and of being closer to one’s business suppliers for efficient running of the business. Like in all other countries where these industries exist, it is vital that the cable manufacturing industry survives and prospers in South Africa, for the benefit of South African telecommunications, electricity suppliers, computer networks and many more industries. However, today there are almost no boundaries in business owing to globalization which enhances free trade. The business environment is changing and there is fierce competition amongst international rivals. What happens then when customers are not happy with low quality products of one supplier? Would they not leave that supplier and look to the competition in order to get good quality products at reasonable prices? Of course they would. Consequently such a supplier would lose market share and ultimately be forced out of business. This research investigates the shortcomings in terms of the implementation of the principles of total quality and technology management in the cable manufacturing industry. It identifies the internationally recognised principles in the fields of total quality management and technology management as a means of enhancing a competitive advantage. Training and development are identified as extremely important supporting mechanisms which should be done professionally for the best results in the implementation of total quality and technology management principles. Finally, suggestions and recommendations based on best management practice are made.

- Description: The research problem in this study was to analyse how the new constitutional, legal and political arrangements have influenced public policy-making in the department of labour with specific reference to the Employment Equity Act. To achieve this objective a theory for analysing policy–making process was presented. Corporatist theory is based on the following assumptions: Public policy is shaped by interaction between the state and interest groups. The state licences behaviour of interested organizations by attributing public status to them Policy-making is based on interest groups bargaining across a broad range of issues. The groups are functionally interdependent to enhance social stability. The groups use consensus in making decisions. Decision-making is centralised, it is done by leaders. The groups are bureaucratic in organization. The groups must be recorgnised by the state so that they can be allowed representation. The research questions that arise are: (1) Who sets the agenda for policy formulation? (2) How is the policy formulated? (3) how are the decisions taken? (4) How is the policy implemented? (5) How is the policy monitored? The objective of this study analyse how constitutional, legal and political changes have influenced public policy formulation in the Department of Labour with specific reference to the Employment Equity Act. Policy–making processes in the South African arena and factors that led to the promulgation of Employment Equity Act were discussed. This study was a qualitative design. Purposive sampling was used in the selection of five participants who were interviewed. All interviews were transcribed verbatim. Data was analysed as described by Rubin and Rubin (1995:260) The result negated some of the assumptions of corporatist theory and others concurred with the theory. The findings of the study revealed that policy formulation in the Department of Labour is as a result of constitutional, and international conventions obligations. The findings further revealed that policy-information is institutionalised and there are competing interests due to divergent ideological orientations, different social backgrounds; racial differences; different; political beliefs; different class background; different historical backgrounds, and gender differences. (v) The formulation of the act was also characterised by advocacy, adversarism, stereotyping, alliances and consensus. These organisations. were bureaucratic and decisions were centralised. This study recommended a theory and the theory postulates that “public policy is the product of the social, economic, political, cultural, technolergical, and natural conditions of a given society in a particular epoch or period in the historical development of the particular nation or society and is influenced by dominant national and international forces and these influences may be cultural, economically, social, politically, technological, and type and system of government.

- Description: This study is a contribution to the ongoing debate concerning the role and involvement of foreign donor entities in the processes of transforming and creating viable and sustainable municipal entities in South Africa. The discussion particularly focuses on the relationship between the donor community and the Department of Provincial and Local Government (DPLG) and how this relationship has been nurtured, coordinated and managed. The study acknowledges the challenges pertaining to local government transformation and the role and mandate assigned to the DPLG by the South African Constitution and the Presidential Coordinating Council (PCC) for it to facilitate the creation of developmental local government. In discussing this, consideration is given to capacity and resource constraints within the Department, which necessitate that it collaborates closely with other stakeholders, particularly donors, in seeking to augment its resource base and capacity. The Department's lack of capacity is further complicated by the various pieces of legislation, which have a serious bearing on how municipalities have to work - irrespective of their capacity and resources limitations. The research also focuses on how this relationship, between the DPLG and foreign aid donors working in the local government sector, is coordinated and managed. From evidence gathered and interviews conducted, the conclusion is drawn that there is much room for the DPLG to improve and strategically focus its interaction with donors as informed by its mandate and strategic priorities. Proposals, which entail development of donor management guidelines, setting up of a donor coordination unit within DPLG, the improvement of the understanding of donor work politics and modalities among DPLG officials, etc., are made.

- Description: The main problem of this study was to assess the communication strategies used by GIRSS to achieve organisational goals. To address this problem, a theoretical study was undertaken to identify the communication strategies used in organisations. The theoretical guidelines for effective communication were integrated into a communication model, which consisted of the following components: · The establishment of organisational communication structures; · The selection of appropriate communication media; IV · The management of communication barriers; and · Addressing the challenges in organisational communication. Based on the model, a survey questionnaire was developed to assess the extent to which GIRSS made use of these strategies. The questionnaire was administered to both managers and non-managers in the organisation. Due to the distance between South Africa and China, the questionnaire was administered via e-mail. The empirical results revealed that some of the theoretical guidelines were followed, but there was room for improvement in terms of communication strategies used at GIRSS. Specifically it was found that many barriers existed as a result of status and other differences, which influenced communication in the organisation. Communication in organisations is very important as it contributes to goal attainment, satisfaction, cooperation and problem-solving. Communication is a skill that can be learned, and managers as well as employees should consider the results of the study to initiate changes to the communication strategies used in the organization.

- Description: The development of conservation and management programs for an animal population relies on a knowledge of the number of individuals in an area. In order to achieve reliable estimates, precise and accurate techniques for estimating population densities are needed. This study compared the use of direct and indirect methods of estimating kudu (Trage/aphus strepsiceras), bush buck (Trage/aphus scriptus), common duiker (Sy/vicapra grimmia), and blue duiker (Philantamba manticala) densities on Shamwari Game Reserve in the Eastern Cape Province, South Africa. These species prefer habitats of dense forest and bush for concealment and are therefore not easily counted in open areas. Herein direct observation counts were compared to indirect sampling via pellet group counts (clearance plots, line transects, variable-width transects, and strip transects). Clearance plots were examined every 2 weeks, while all other methods were conducted seasonally, from August 2002 until August 2003. The strip transect method provided the lowest density estimates (animals per hal ranging from 0.001 for bushbuck to 0.025 for common duiker, while direct observations yielded the highest estimates, ranging from 0.804 for bush buck to 4.692 for kudu. Also, a validation of methods was performed against a known population of kudu during which the DISTANCE method yielded the most accurate results, with an estimated density of 0.261 that was within the actual density of 0.246 to 0.282. In addition, the DISTANCE method was compared to helicopter counts ofkudu and its estimates were found to be approximately 2.6 times greater than the helicopter count results. When the assessment of the methods was made, the cost, manpower and effort requirements, coefficient of variation, and performance against a known population for each method were taken into consideration. Overall, the DISTANCE method performed the best with low cost, minimal manpower and effort requirements, and low coefficient of variation. On Shamwari Game Reserve, the DISTANCE method estimated 0.300 kudu, 0.108 bushbuck, 0.387 common duiker, and 0.028 blue duiker per ha, which, when extrapolated to the total number of animals present within subtropical thicket habitat, estimated 1973 kudu, 710 bush buck, 2545 common duiker, and 184 blue duiker.
