  • Notes on the morphology, ecology and distribution of Quisqualis parviflora

    • Authors: Richard G.C. Boon
      First page: 5
      Abstract: Background: Quisqualis parviflora Gerrard ex. Sond. is endemic to the KwaZulu-Natal and Eastern Cape provinces, South Africa. The species’ distribution has previously been thought to extend to Mpumalanga and the KwaZulu-Natal midlands. Most published distributions include Maputaland in north-eastern KwaZulu-Natal, and it has been suggested that the species may occur in Mozambique. Sterile material of several Combretum Loefl. lianas may be confused with Q. parviflora.Although the species may be locally common, it has never been collected in fruit. Published fruit descriptions are based on erroneously identified material.Objectives: The aim of this study was to supply a revised distribution range, to describe the fruit of Q. parviflora and to present notes on the phenology and ecology of the species.Method: Herbarium specimens of Q. parviflora, and similar taxa, were examined in various herbaria. Fieldwork was undertaken, and other active field botanists were consulted.Results: Quisqualis parviflora is almost entirely restricted to scarp forest between Port St. Johns in the Eastern Cape and Eshowe in KwaZulu-Natal. Although the species may be locally common, it has only been collected from a few localities. The current dispersal ability of the species may be extremely limited, which could have long-term conservation implications.Samaras are described, and notes are provided on the phenology and ecology of the species.Conclusion: Although not currently threatened, the long-term prospects of Q. parviflora may be less secure. Proposed forest management interventions like liana thinning should not be undertaken without more information.

    • Authors: Rachel H. Palfrey, Jack Baddams, Bruno A. Raveloson, Solohery Rasamison, Fionn Ó Marcaigh, Jamie Neaves, Peter R. Long, Thomas E. Martin
      First page: 7
      Abstract: Background: The West Malagasy dry forests support numerous endemic species and experience heavy anthropogenic pressures, yet remain very poorly studied. Further research is required to understand species distributions and overall diversity in these threatened forest ecosystems.Objectives: We aimed to provide a description of the avifaunal community of a particular dry forest, Mariarano forest, north-western Madagascar, as well as other habitats that are heavily integrated with these Forests. The study site possesses a highly endemic bird community and is under severe environmental pressure, but remains poorly explored.Method: We compiled all records from a 9-year (2010–2018) bird survey data set (the most extensive compiled from a Madagascan dry forest to date), which yielded data from a combination of point count and mist-netting protocols. This was further supplemented by approximately 4384 h of opportunistic observation effort.Results: In total, 95 species were detected, including 63 regional endemics (66.3% of all species), 2 local endemics and 7 Threatened or Near-Threatened species.Conclusion: We highlight the forest mosaic habitats of Mariarano as a potential new Important Bird Area, given the regional importance of its endemic avifauna.

  • Invasive alien plants occurring in Lesotho: Their ethnobotany, potential
           risks, distribution and origin

    • Authors: Khotso Kobisi, Lerato Seleteng-Kose, Annah Moteetee
      First page: 11
      Abstract: Background: Several recent studies have documented the ethnobotanical uses of plants used in Lesotho, in particular those used for medicinal purposes. However, these reports did not make a distinction between indigenous, naturalised or invasive alien plants. Furthermore, the existing records on the status of the occurrence of these plants in the country are not up to date.Objectives: The aim of this article is to present information on the current knowledge regarding the status of invasive alien plant species in Lesotho and to discuss their ethnobotanical uses, distribution in the country, origin and safety. We further assess the existing legislation designed to regulate the spread of such plants and make a comparison with the invasiveness and regulation of such plants in the neighbouring South Africa.Method: This article is based mainly on a literature survey of published information obtained from various databases, such as Google Scholar, Science Direct and Scopus, as well as from unpublished data such as technical reports, dissertations and theses.Results: A total of 57 species, comprising one pteridophyte, one gymnosperm and 56 flowering plants (52 dicotyledons and 4 monocotyledons) are documented. Although these plants are invasive in nature, they are utilised for a variety of purposes including food, treatment of various medical conditions, cosmetics and functional uses. However, some of the species are reported to be poisonous to both animals and humans, with a majority of the plants causing skin irritation. Most of these species are widely distributed throughout the country and most of them originated from America, Europe and Asia. Although a number of reports on the occurrence of invasive alien plants have been generated, the information therein has not yet been published.Conclusion: This study has identified knowledge gaps in terms of safety and distribution of the species, as well as shortfalls in the policies intended to regulate invasive alien species (IAS) in Lesotho. Further research in this regard is therefore recommended.

  • Vegetation Map of South Africa, Lesotho and Swaziland 2018: A description
           of changes since 2006

      Abstract: Background: The Vegetation Map of South Africa, Lesotho and Swaziland (National Vegetation Map [NVM]) is a fundamental data set that is updated periodically. The National Biodiversity Assessment (NBA) 2018 process provided an opportunity for a more comprehensive revision of the NVM and better alignment between the terrestrial, marine and estuarine ecosystem maps.Objectives: The aim of this study was to update the NVM 2018 and quantify spatial and classification changes since NVM 2012, and describe the rationale and data sources utilised. We also quantified spatial errors corrected in this version, highlighted progress since NVM 2006, and identified errors and gaps to make recommendations for future revisions.Method: Edits made to the NVM in ArcMap 10.4 were categorised into the following five groups for analysis: (1) New types, (2) Boundary edits, (3) Realm re-assignment, (4) Removed and replaced vegetation types and (5) Deleted map area. Changes were quantified by category and biome. We used various software platforms to correct and quantify spatial errors since 2006.Results: Vegetation types were added (n = 47), removed (n = 35) and had boundary edits (n = 107) in NVM 2018, which affected over 5% of the total map area, compared to 2.6% (2012) and 0.5% (2009) for previous versions. Several sources of error were identified and fixed, and prompted the development of standard mapping protocols.Conclusion: National Vegetation Map 2018 is the most substantial revision of this data set that now fully aligns with maps of all other realms that form part of the NBA. However, parts of the map remain unrefined and provide opportunities for future work.

  • Honeybush (Cyclopia spp.) phenology and associated arthropod diversity in
           the Overberg region, South Africa

    • Authors: Eleonore L. Slabbert, Rhoda R. Malgas, Ruan Veldtman, Pia Addison
      First page: 13
      Abstract: Background: Cyclopia is endemic to regions of the Cape Floristic Region across the Eastern and Western Cape provinces of South Africa and is commonly known as honeybush. Honeybush has historically been used as an herbal tea, and has proven medicinal properties. Honeybush biomass and extracts are used in the functional foods and cosmetics sectors, both locally and overseas. The growing demand for honeybush calls for increased agricultural production and a shift away from the predominantly wild harvested supply.Objectives: The current study aimed to address the lack of baseline knowledge on honeybush phenology and its associated arthropod community to advance sustainable production of commercially valued plants in the genus.Method: The study was conducted on wild and cultivated Cyclopia species (Cyclopia maculata and Cyclopia genistoides) at respective sites in the Overberg region. Sampling took place from April 2014 to April 2015 using qualitative methods for recording seasonal honeybush phenology and suction sampling for aboveground arthropods. Focal insect taxa (Coleoptera, Hemiptera, Thysanoptera, Lepidoptera and Hymenoptera) were sorted and identified to family level and classified into functional feeding guilds.Results: Qualitative phenology observations of wild C. maculata and cultivated C. genistoides indicated a high level of congruency in seasonality of phenophase stages. Associated arthropod assemblages contained a diversity of families per functional feeding group, namely phytophagous, zoophagous and omnivorous taxa, with high seasonal variability.Conclusion: Findings highlight the complexity of ecological elements to be taken into consideration for ecologically sound honeybush cultivation. Outcomes can be applied to land management practices and governance policies promoting sustainable agroecosystems in honeybush production areas.

  • Spider checklist for the Blouberg, in the Vhembe Biosphere Reserve, South

    • Authors: Stefan Foord, Anna S. Dippenaar-Schoeman, Charles R. Haddad, Colin Schoeman, Norbert Hahn, Robin Lyle
      First page: 13
      Abstract: Background: The north-eastern mountainous region of South Africa has been identified as a spider diversity hotspot and centre of endemisim. The Blouberg is an isolated inselberg that forms part of the Soutpansberg geological complex, the northernmost mountain in South Africa.Objectives: This article provides an updated species list of the Blouberg spiders, which includes details of the distribution patterns and conservation statuses of all taxa. Exotic species and species of special conservation concern are identified.Method: Surveys were conducted between 2005 and 2012, and a range of collecting methods were used to sample both the ground and field layers.Results: A total of 47 families were sampled in 210 genera and 346 species. The families of Salticidae (45 spp.), Gnaphosidae (32 spp.), Thomisidae (31 spp.), Araneidae (26 spp.) and Lycosidae (24 spp.) were the most diverse. Five species are of conservation concern, one species is Vulnerable, one is possibly exotic and 62 species are South African endemics.Conclusion: Presently, 17% of South African species are protected on the mountain and its surrounding foothills. The latter are of particular conservation concern, while the mountaintop and its associated habitats are under-sampled.

  • Has strategic planning made a difference to amphibian conservation
           research in South Africa'

    • Authors: John Measey, Jeanne Tarrant, Alex Rebelo, Andrew Turner, Louis du Preez, Mohlamatsane Mokhatla, Werner Conradie
      First page: 13
      Abstract: Background: Conservation relies on the strategic use of resources because monies for conservation action are limited, especially in developing countries. South Africa’s Frog Atlas project established a baseline for the country’s amphibian data and threat levels in 2004, and in 2009 a prioritisation exercise developed a strategy for conservation research.Objectives: In this article, we assess this strategy for conservation research.Method: We conducted a quantitative and qualitative assessment of research undertaken since the strategy was developed.Results: The strategy has produced a lasting impact on taxonomy, ecological studies, monitoring and capacity building. Publications in all areas have increased, but particularly in conservation ecology. Other indicators are increases in the numbers of locality records for target taxa, species descriptions and postgraduate degrees with amphibians as the principal topic. We document important milestones for South African amphibian conservation, including the first Biodiversity Management Plan for Species (BMP-S) for Hyperolius pickersgilli, a smart device app that uploads locality data to an open access database, 15 years of monitoring data and new amphibian identification books for adults and children. The Red List Index calculated for South African amphibians shows that the country’s species are becoming more threatened (a 1% reduction in 10 years), but a hindcasting exercise suggests that most of the damage was already done by 1990. We provide a checklist for 131 amphibian species in South Africa, of which 82 species are endemic.Conclusion: A strategy for conservation research was found to greatly augment the focus of research on South African frogs. A new strategy should focus on fewer taxa over meaningful time spans.

  • Using large-scale citizen science ringing data as a means of calculating
           maximum longevity in birds

    • Authors: Dane M. Paijmans, Sanjo Rose, Hans-Dieter Oschadleus
      First page: 15
      Abstract: This article calculates estimates of avian longevity for southern African Passeriformes and demonstrates the impact citizen scientists have on data volumes curated by the South African Bird Ringing Unit (SAFRING). We calculated taxon-specific longevity records for 341 species from 33 families using ringing data collected between 1948 and 2017. An increase in active ringer participation over time correlated positively with an increase in retrap and recovery data, allowing for more reliable longevity calculations. These results highlight the significant contribution citizen scientists have made to bird ringing in southern Africa and identify data-deficient taxa to which future ringing activities should be targeted.
