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. -

Investigating the Impact of Fire on the Natural Regeneration of Woody Species in Dry and Wet Miombo Woodland
Investigating the impact of fire on the natural regeneration of woody species in dry and wet Miombo woodland by Paul Mwansa Thesis presented in fulfilment of the requirements for the degree of Master of Science of Forestry and Natural Resource Science in the Faculty of AgriSciences at Stellenbosch University Supervisor: Prof Ben du Toit Co-supervisor: Dr Vera De Cauwer March 2018 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. 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. -
Flowering of Watsonia Laccata As Influenced by Corm Storage and Forcing Temperatures ⁎ J.K
Available online at www.sciencedirect.com South African Journal of Botany 77 (2011) 631–637 www.elsevier.com/locate/sajb Flowering of Watsonia laccata as influenced by corm storage and forcing temperatures ⁎ J.K. Suh a, , J.H. Kim a, A.K. Lee a, M.S. Roh b a Dankook University, College of Bio-Resources Science, Department of Environmental Horticulture, Cheonan, Chungnam 330-714, Republic of Korea b US Department of Agriculture, Agricultural Research Service, National Arboretum, Floral and Nursery Plants Research Unit, Beltsville MD 20705, USA Received 24 March 2010; received in revised form 28 November 2010; accepted 22 December 2010 Abstract The genus Watsonia, belonging to the family Iridaceae, is comprised of about 50 species including W. laccata (Jacquin) Ker Gawler that flowers from September to November following low temperature and winter rainfall. Therefore, we hypothesized that flowering would be favored by forcing at low greenhouse temperatures. Using clonal W. laccata corms, four experiments were designed to investigate the effect of temperatures during corm storage, forcing, and their interaction on growth and flowering. Corm formation is favored by growing plants at 18°– 20°/15°–17 °C and 21°–23°/18°–20 °C, day/night temperatures. Flowering was earliest with corms produced at 24°–26°/18°–20 °C and forced at 18°–20/15°–17 °C, and was significantly delayed when forced at 27°–29°/24°–26 °C. Flowering was, however, favored by 2 or 4 weeks of high temperatures (27°–29°/24°–26 °C) prior to forcing at low temperatures (18°–20°/15°–17 °C). The number of florets was not significantly affected by corm storage, forcing temperatures, or their interaction, although forcing at high temperatures tends to reduce the floret number. -

Although this year has thrown many obstacles our way, we feel that the “show must go on.” In response to the COVID-19 situation, this year will look a little different. For the safety of our members and our customers, this year will be an online pre-order only sale. Our mission stays the same: to support our community’s green spaces, and to educate our community in the areas of gardening, horticulture, conservation, and related topics. GCH members serve as volunteers, and our profits from the Bulb Mart are given back to WELCOME the community in support of our mission. In the last fifteen years, we have given back over $3.5 million in grants to the community! The Garden Club of Houston’s first Plant Sale was held in 1942, on the steps of The Museum of Fine Arts, Houston, with plants dug from members’ gardens. Plants propagated from our own members’ yards will be available again this year as well as plants and bulbs sourced from near and far that are unique, interesting, and well suited for area gardens. -

Vegetation of the Central Kavango Woodlands in Namibia: an Example from the Mile 46 Livestock Development Centre ⁎ B.J

Strohbach a, , A. Petersen b a National Botanical Research Institute, Private Bag 13184, Windhoek, Namibia b Institute for Soil Science, University of Hamburg, Allende-Platz 2, 20146 Hamburg, Germany Received 22 November 2006; accepted 7 March 2007 Abstract No detailed vegetation descriptions are available for the Kavango woodlands — recent descriptions have all been at the broad landscape level without describing any vegetation communities. With this paper the vegetation associations found at and around the Mile 46 Livestock Development Centre (LDC) are described. Two broad classes are recognised: the Acacietea are represented by three Acacia species-dominated associations on nutrient-richer eutric Arenosols, whilst the Burkeo–Pterocarpetea are represented by three associations dominated by broad-leafed phanerophytic species on dystri-ferralic Arenosols. The, for the Kavango woodlands typical, Pterocarpus angolensis–Guibourtia coleosperma bushlands and thickets are further divided into four variants. Fire has been found to be an important factor in determining the structure of the vegetation — exclusion of fire on the LDC itself seems to lead to an increase in shrub (understory) density. © 2007 SAAB.
