  • Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi
    YIKA-VWAZA TRUST RESEARCH STUDY REPORT N (2017/18) Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi By Sopani Sichinga ([email protected]) September , 2019 ABSTRACT In 2018 – 19, a survey on vascular plants was conducted in Vwaza Marsh Wildlife Reserve. The reserve is located in the north-western Malawi, covering an area of about 986 km2. Based on this survey, a total of 461 species from 76 families were recorded (i.e. 454 Angiosperms and 7 Pteridophyta). Of the total species recorded, 19 are exotics (of which 4 are reported to be invasive) while 1 species is considered threatened. The most dominant families were Fabaceae (80 species representing 17. 4%), Poaceae (53 species representing 11.5%), Rubiaceae (27 species representing 5.9 %), and Euphorbiaceae (24 species representing 5.2%). The annotated checklist includes scientific names, habit, habitat types and IUCN Red List status and is presented in section 5. i ACKNOLEDGEMENTS First and foremost, let me thank the Nyika–Vwaza Trust (UK) for funding this work. Without their financial support, this work would have not been materialized. The Department of National Parks and Wildlife (DNPW) Malawi through its Regional Office (N) is also thanked for the logistical support and accommodation throughout the entire study. Special thanks are due to my supervisor - Mr. George Zwide Nxumayo for his invaluable guidance. Mr. Thom McShane should also be thanked in a special way for sharing me some information, and sending me some documents about Vwaza which have contributed a lot to the success of this work. I extend my sincere thanks to the Vwaza Research Unit team for their assistance, especially during the field work.

Pol Coppin2 Laboratory for Forest, Nature and Landscape Research, Katholieke Universiteit Leuven, Vital Decosterstraat 102, 3000 Leuven, Belgium and Hans Beeckman3 Laboratory for Wood Biology and Xylarium, Royal Museum for Central Africa, Leuvensesteenweg 13, 3080 Tervuren, Belgium ABSTRACT The availability of exactly dated tree-ring chronologies is limited in tropical regions. However, these chronologies could contribute widely to studies of the influence of natural and human-induced factors on tropical forests. We examine the potential for building a chronology based on three sites in the miombo woodland of western Zambia. Brachystegia spiciformis Benth., a dominant species from this vegetation type, is used. Response of the chronology to several climatic factors is examined. All specimens showed very clear growth rings, and cross-dating between radii of a tree was successful for all trees. Site chronologies could be constructed after cross-dating of growth ring series of individual trees. The mean growth ring curves of the three sites were significantly similar, allowing for the construction of a regional chronology. Correlation function analysis between the tree-ring chronology and regional climatic variables revealed that climate at the core of the rainy season, in December and January, has an explicit influence on tree growth. Where precipitation and relative humidity in these months influence tree growth positively, temperature correlates in a negative way.

  • 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.

The plant genus Strelitzia occurs naturally in the eastern parts of southern Africa. It comprises three arbores- cent species, known as wild bananas, and two acaulescent species, known as crane flowers or bird-of-paradise flowers. The logo of SANBI is partly based on the striking inflorescence of Strelitzia reginae, a native of the Eastern Cape and KwaZulu-Natal that has become a garden favourite worldwide. It symbolises the commitment of SANBI to champion the exploration, conservation, sustainable use, appreciation and enjoyment of South Africa’s excep- tionally rich biodiversity for all people.

  • Vegetation Survey of Mount Gorongosa
    VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 Biodiversity Foundation for Africa P.O. Box FM730, Famona, Bulawayo, Zimbabwe Vegetation Survey of Mt Gorongosa, page 2 SUMMARY Mount Gorongosa is a large inselberg almost 700 sq. km in extent in central Mozambique. With a vertical relief of between 900 and 1400 m above the surrounding plain, the highest point is at 1863 m. The mountain consists of a Lower Zone (mainly below 1100 m altitude) containing settlements and over which the natural vegetation cover has been strongly modified by people, and an Upper Zone in which much of the natural vegetation is still well preserved. Both zones are very important to the hydrology of surrounding areas. Immediately adjacent to the mountain lies Gorongosa National Park, one of Mozambique's main conservation areas. A key issue in recent years has been whether and how to incorporate the upper parts of Mount Gorongosa above 700 m altitude into the existing National Park, which is primarily lowland. [These areas were eventually incorporated into the National Park in 2010.] In recent years the unique biodiversity and scenic beauty of Mount Gorongosa have come under severe threat from the destruction of natural vegetation. This is particularly acute as regards moist evergreen forest, the loss of which has accelerated to alarming proportions.
