Eastern mistbelt forests are naturally fragmented forests with grassland which occur from the Eastern Cape to KwaZulu-Natal, South Africa. These were heavily logged by colonial settlers and continue to be harvested despite being protected. Consequently we documented a checklist of the plants of the forests and grasslands in the Weza district (3029DA WEZA), southern KwaZulu-Natal, including Ngeli Forest and nearby indigenous forest patches to highlight their biodiversity status and need for conservation. We also reviewed their status in the Red Data List. Of the 1554 records included in this summary of plant species for the Weza district, there were 6 lichens (0.4%), 46 bryophytes (3.0%), 58 pteridophytes (3.7%), 6 gymnosperms (0.4%) and the remaining 1424 species angiosperms (92.5%). Of the angiosperms, 27.3% were monocotyledons and 72.7% were dicotyledons. The most species-rich family was Asteraceae (239 species) followed by Fabaceae (115 species), Liliaceae (used for purposes of comparison against older studies – 89 species), Orchidaceae (89 species), Iridaceae (59 species), Poaceae (58 species), Asclepidaceae (again used for purposes of comparison against older studies – 57 species), Scrophulariaceae (42 species), Euphorbiaceae (32 species), Lamiaceae (32 species) and Rubiaceae (27 species). These 10 families each comprised more than 2% of the species in the list. Together they contributed 55% of the angiosperm species and 34.1% of the angiosperm genera. The biodiversity and conservation value of the study area are conserved pockets of eastern mistbelt forest, Drakensberg foothill moist grassland and mistbelt grassland. More than 4% of the species are under some degree of threat, as was evidenced by the number of species regarded as endangered (5), vulnerable (18), near threatened (10), critically rare (1), rare (20) or declining (11) amongst the 1554 species covered in the list.Conservation implications: In terms of taxa under some degree of threat, number of endemic and near endemic species the biodiversity and conservation value of the Ngele (3029DA WEZA) area is reinforced. This necessitates that the area is appropriately protected from invasive alien species, and uncontrolled and illegal use by the neighbouring communities.

SummaryThe Cape Parrot Poicephalus robustus is a habitat specialist, restricted to forest patches in the Eastern Cape (EC), KwaZulu-Natal (KZN) and Limpopo provinces of South Africa. Recent census estimates suggest that there are less than 1,600 parrots left in the wild, although historical data suggest that the species was once more numerous. Fragmentation of the forest biome is strongly linked to climate change and exploitation of the forest by the timber industry. We examine the subpopulation structure and connectivity between fragmented populations across the distribution of the species. Differences in historical and contemporary genetic structure of Cape Parrots is examined by including both modern samples, collected from 1951 to 2014, and historical samples, collected from 1870 to 1946. A total of 114 individuals (historical = 29; contemporary = 85) were genotyped using 16 microsatellite loci. We tested for evidence of partitioning of genotypes at both a temporal and spatial scales by comparing shifts in allelic frequencies of historical (1870–1946) and contemporary (1951–2014) samples across the distribution of the species. Tests for population bottlenecks were also conducted to determine if anthropogenic causes are the main driver of population decline in this species. Analyses identified three geographically correlated genetic clusters. A southern group restricted to forest patches in the EC, a central group including birds from KZN and a genetically distinct northern Limpopo cluster. Results suggest that Cape Parrots have experienced at least two population bottlenecks. An ancient decline during the mid-Holocene (∼ 1,800-3,000 years before present) linked to climate change, and a more recent bottleneck, associated with logging of forests during the early 1900s. This study highlights the effects of climate change and human activities on an endangered species associated with the naturally fragmented forests of eastern South Africa. These results will aid conservation authorities with the planning and implementation of future conservation initiatives. In particular, this study emphasises the Eastern Cape mistbelt forests as an important source population for the species and calls for stronger conservation of forest patches in South Africa to promote connectivity of forest taxa.

Background: Many European-trained doctors (ETDs) recruited to work in rural district hospitals in South Africa have insufficient generalist competencies for the range of practice required. Africa Health Placements recruits ETDs to work in rural hospitals in Africa. Many of these doctors feel inadequately prepared. The Stellenbosch University Ukwanda Centre for Rural Health is launching a Postgraduate Diploma in Rural Medicine to help prepare doctors for such work.Aim: To determine the competencies gap for ETDs working in rural district hospitals in South Africa to inform the curriculum of the PG Dip (Rural Medicine).Setting: Rural district hospitals in South Africa.Methods: Nine hospitals in the Eastern Cape, KwaZulu-Natal and Mpumalanga were purposefully selected by Africa Health Placements as receiving ETDs. An online survey was developed asking about the most important competencies and weaknesses for ETDs when working rurally. The clinical manager and any ETDs currently working in each hospital were invited to complete the survey.Results: Surveys were completed by 19 ETDs and five clinical managers. The top clinical competencies in relation to 10 specific domains were identified. The results also indicate broader competencies required, specific skills gaps, the strengths that ETDs bring to South Africa and how ETDs prepare themselves for working in this context.Conclusion: This study identifies the important competency gaps among ETDs and provides useful direction for the diploma and other future training initiatives. The diploma faculty must reflect on these findings and ensure the curriculum is aligned with these gaps.

Summary Establishing the specific habitat requirements of forest specialists in fragmented natural habitats is vital for their conservation. We used camera-trap surveys and microhabitat-scale covariates to assess the habitat requirements, probability of occupancy and detection of two terrestrial forest specialist species, the Orange Ground-thrush Geokichla gurneyi and the Lemon Dove Aplopelia larvata during the breeding and non-breeding seasons of 2018–2019 in selected Southern Mistbelt Forests of KwaZulu-Natal and the Eastern Cape, South Africa. A series of camera-trap surveys over 21 days were conducted in conjunction with surveys of microhabitat structural covariates. During the wet season, percentage of leaf litter cover, short grass cover, short herb cover, tall herb cover and saplings 0–2 m, stem density of trees 6–10 m and trees 16–20 m were significant structural covariates for influencing Lemon Dove occupancy. In the dry season, stem density of 2–5 m and 10–15 m trees, percentage tall herb cover, short herb cover and 0–2 m saplings were significant covariates influencing Lemon Dove occupancy. Stem density of trees 2–5 m and 11–15 m, percentage of short grass cover and short herb cover were important site covariates influencing Orange Ground-thrush occupancy in the wet season. Our study highlighted the importance of a diverse habitat structure for both forest species. A high density of tall/mature trees was an essential microhabitat covariate, particularly for sufficient cover and food for these ground-dwelling birds. Avian forest specialists play a vital role in providing ecosystem services perpetuating forest habitat functioning. Conservation of the natural heterogeneity of their habitat is integral to management plans to prevent the decline of such species.

Human Rabies Case

SUMMARYThe KwaZulu Natal and Eastern Cape provinces of South Africa have experienced a serious dog rabies epidemic over the past three decades. Towards a better understanding of this epidemic, we have previously analysed nucleotide sequences of 142 rabies virus specimens that were obtained from these regions during 2003–2004 and provided a molecular description of the geographical distribution of rabies viral variants in the affected provinces. Here, as an extension, we studied five human cases that occurred during 2002–2003 and demonstrated the use of the sequence database in tracking unknown human rabies case histories. We were able to identify the geographical origin of viruses responsible for each human infection and in one case obtained evidence that suggested a non-bite transmission of rabies virus from an infected dog to a child. We argue for the value of this information in surveillance and epidemiological study and in the follow-up and management of potential exposures.
