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. -

Aspe2cts of the Accumulation of Cobalt, Copper and Nickal by Plants A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Chemistry Massey University Richard Stephen Morrison 1980 ti"aao_J� ii Abstract Hyperaccumulation of heavy metal s was st udied with the intention of elucidating the mechanisms of tolerance of hyperaccumulator plant species. Two main areas are covered; cobalt and copper accumulation by plants from Shaba Province, Zaire, and nickel accumulation by species of the genus Alyssum. In surveys of vegetation of metalliferous soils of Shaba, nine or ten new hyperaccumulators of cobalt were discovered along with eight or nine very strong accumulators. For copper, seven hyperaccumulators and five or six very strong accumulators were discovered. Same families contained a higher frequency of hyperaccumulators than others. There is also a difference in superarder classification of cobal t and copper hyperaccumulators on one hand and nickel hyperaccumulators on the other. Surveys of the genera Aeolanthus, Ipomoea and Pandiak a were made but only one new copper hyperaccumulator was found: no new cobalt hyperaccumulators were found. Several species had their abilities to accumulate confirmed. Pot trial s on three hyperaccumulators Aealanthus biformifalius, Haumaniastrum katangense and �· rabertii, showed accumulation of cobalt but not the expected accumulation of copper. The uptake curve was of the exclusion-breakdown form . -

Pref. Lothário Meissner, 632, Jardim Botânico, 80.210-170, Curitiba, PR, Brazil, phone (55) 41 – 3360-4275, [email protected] SUMMARY Wood trade is strongly dependent on global economic conditions. In Africa, the market for tropical wood also has dynamic changes. In Mozambique, the international demand for wood comes mainly from emerging economies such as China and India. Almost 70 % of the country is still covered by forests and other woody vegetation. There are many species with favorable properties for wood commerce, although, at present, this is restricted to a few species. We analyzed the wood anatomy of Acacia nigrescens, Combretum imberbe, Icuria dunensis, Pericopsis angolensis and Sterculia appendiculata and comment about properties and potential use based on their anatomical composition. In general, the species presented wood diffuse pores, simple perforation plates, alternate intervessel pits, deposits in vessels; abundant axial parenchyma; multiseriate rays, very thick-walled fibers and mineral inclusions. Based on anatomical characteristics, the studied species have great potential for use in panels industry, furniture, floor, structures and craftwork. -
SABONET Report No 18
ii Quick Guide This book is divided into two sections: the first part provides descriptions of some common trees and shrubs of Botswana, and the second is the complete checklist. The scientific names of the families, genera, and species are arranged alphabetically. Vernacular names are also arranged alphabetically, starting with Setswana and followed by English. Setswana names are separated by a semi-colon from English names. A glossary at the end of the book defines botanical terms used in the text. Species that are listed in the Red Data List for Botswana are indicated by an ® preceding the name. The letters N, SW, and SE indicate the distribution of the species within Botswana according to the Flora zambesiaca geographical regions. Flora zambesiaca regions used in the checklist.

Date: March 2018 Copyright © 2018 Stellenbosch University All rights reserved i | Page Stellenbosch University https://scholar.sun.ac.za Abstract The importance of indigenous tree species to local livelihoods can never be overstated. The species provide wood materials and non-woody resources, such as fruits and traditional medicines. Pterocarpus angolensis and Strychnos cocculoides are two important tree species found in a Namibian and adjacent countries’ woodlands. Local people highly depend on the trees for wood (P. angolensis) and fruits (S. cocculoides). Due to over-exploitation of P. angolensis and S. cocculoides, the trees are on the verge of getting extinct. For instances; P. angolensis is mostly used for its ever-demanded wood products, thus become vulnerable to immense cutting down. Several attempts to propagate these two-tree species using traditional/conventional method i.e. -
