The species is confined to lowland tropical forests on the deep Kalahari sands between 13 and 20°S. It oc- curs naturally in Angola, Botswana, Namibia, Zambia and Zimbabwe, in areas with annual rainfall of 600- 1000 mm and a dry season of 6-8 months. Mature trees can withstand extreme temperatures of over 40°C and have been known to survive severe frost down to -15°C. It is mainly found in deep, infertile, sandy soils where it survives by developing a deep tap root. During the last century, most of the original Zambesi teak forests have been heavily exploited by logging, clearing of land for agriculture and frequent fires and the species is now mainly found in open, dry, deciduous woodland. The species is most typically associated with Pterocarpus angolensis, Julbernardia paniculata, Dialium englerianum.

Fax: +27 31 907 7665. Accepted 7 December, 2010 Ethnobotanical survey of Bulbine Wolf, (Asphodelaceae) used for various treatment, such as, diarrhea, burns, rashes, blisters and insect bites, was carried out in the Eastern Cape Province of South Africa. Information on the parts used and the methods of preparation was collected through questionnaire which was administered to the herbalists, traditional healers and rural dwellers which indicated the extensive use of Bulbine species. Most uses of Bulbine species closely resemble that of Aloe . Dried leaf bases and leaf sap are the commonest parts of the plants used. Preparations were in the form of decoctions and infusions. Bulbine frutescens was the most frequently and commonly used of the species collected for the treatment of diarrhoea, burns, rashes, blisters, insect bites, cracked lips and mouth ulcers. The leaf, root and rhizome extracts of B. frutescens, Bulbine natalensis, Bulbine latifolia and Bulbine narcissifolia were screened for antibacterial activities to verify their use by traditional healers.

March 2018 Copyright © 2018 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract The miombo woodland is an extensive tropical seasonal woodland and dry forest formation in extent of 2.7 million km². The woodland contributes highly to maintenance and improvement of people’s livelihood security and stable growth of national economies. The woodland faces a wide range of disturbances including fire that affect vegetation structure. An investigation into the impact of fire on the natural regeneration of six tree species was conducted along a rainfall gradient. Baikiaea plurijuga, Burkea africana, Guibourtia coleosperma, Pterocarpus angolensis, Schinziophyton rautanenii and Terminalia sericea were selected on basis of being an important timber and/or utilitarian species, and the assumed abundance. The objectives of the study were to examine floristic composition, density and composition of natural regeneration; stand structure and vegetation cover within recently burnt (RB) and recently unburnt (RU) sections of the forest.

  • Lake Malawi Destination Guide
    Lake Malawi Destination Guide Overview of Lake Malawi Occupying a fifth of the country, Lake Malawi is the third largest lake in Africa and home to more fish species than any other lake in the world. Also known as Lake Nyasa, it is often referred to as 'the calendar lake' because it is 365 miles (590km) long and 52 miles (85km) wide. Situated between Malawi, Mozambique and Tanzania, this African Great Lake is about 40,000 years old, a product of the Great Rift Valley fault line. There are fishing villages to be found along the lakeshore where residents catch a range of local fish including chambo, kampango (catfish), lake salmon and tiger fish. The export of fish from the lake contributes significantly to the country's economy, and the delicious chambo, similar to bream, is served in most Malawian eateries. Visitors to Lake Malawi can see colourful mbuna fish in the water, while there are also occasional sightings of crocodiles, hippos, monkeys and African fish eagles along the shore. The nearby Eastern Miombo woodlands are home to African wild dogs. Swimming, snorkelling and diving are popular activities in the tropical waters of the lake, and many visitors also enjoy waterskiing, sailing and fishing. There are many options available for holiday accommodation at the lake, including resorts, guesthouses and caravan or camping parks. All budgets are catered for, with luxury lodges attracting the glamorous and humble campsites hosting families and backpackers. Cape Maclear is a well-developed lakeside town, and nearby Monkey Bay is a great holiday resort area. Club Makokola, near Mangochi, is also a popular resort.

  • Reproductive Biology of Aloe Peglerae
    THE REPRODUCTIVE BIOLOGY AND HABITAT REQUIREMENTS OF ALOE PEGLERAE, A MONTANE ENDEMIC ALOE OF THE MAGALIESBERG MOUNTAIN RANGE, SOUTH AFRICA Gina Arena 0606757V A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, in fulfillment of the requirements for the degree of Master of Science Johannesburg, South Africa June 2013 DECLARATION I declare that this Dissertation is my own, unaided work. It is being submitted for the Degree of Master of Science at the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination at any other University. Gina Arena 21 day of June 2013 Supervisors Prof. C.T. Symes Prof. E.T.F. Witkowski i ABSTRACT In this study I investigated the reproductive biology and pollination ecology of Aloe peglerae, an endangered endemic succulent species of the Magaliesberg Mountain Range in South Africa. The aim was to determine the pollination system of A. peglerae, the effects of flowering plant density on plant reproduction and the suitable microhabitat conditions for this species. Aloe peglerae possesses floral traits that typically conform to the bird-pollination syndrome. Pollinator exclusion experiments showed that reproduction is enhanced by opportunistic avian nectar-feeders, mainly the Cape Rock-Thrush (Monticola rupestris) and the Dark- capped Bulbul (Pycnonotus tricolor). Insect pollinators did not contribute significantly to reproductive output. Small-mammals were observed visiting flowers at night, however, the importance of these visitors as pollinators was not quantified in this study. Interannual variation in flowering patterns dictated annual flowering plant densities in the population. The first flowering season represented a typical mass flowering event resulting in high seed production, followed by a second low flowering year of low seed production.

  • Seed Dispersal and Seed Banks in Aloe Marlothii (Asphodelaceae) ⁎ C.T
    Available online at www.sciencedirect.com South African Journal of Botany 78 (2012) 276–280 www.elsevier.com/locate/sajb Short communication Seed dispersal and seed banks in Aloe marlothii (Asphodelaceae) ⁎ C.T. Symes School of Animal, Plant and Environmental Sciences, University of the Witwatersrand, Private Bag 3, WITS 2050, South Africa Received 5 January 2011; received in revised form 1 June 2011; accepted 20 June 2011 Abstract Aloe marlothii flowers during dry winter months (July–September) and produces large numbers of wind dispersed seeds. Fire disturbance in a population of several thousand A. marlothii plants at Suikerbosrand Nature Reserve, Gauteng, permitted a series of seed dispersal experiments to be conducted. Germination trials indicated that seedling emergence decreased with increased distance from a well defined aloe stand and burn area margin, with seeds dispersed up to 25 m. Flowering frequency and total seed production were positively correlated with plant height, with seed production estimated to range from 26,000 to 375,000 seeds/plant. Although a large number of seeds are produced by flowering plants the survival rate of seeds did not extend beyond the following flowering season. © 2011 SAAB. Published by Elsevier B.V.
