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. -

Proceedings of the International Academy of Ecology and Environmental Sciences, 2017, 7(2): 30-46 Article A contemporary assessment of tree species in Sathyamangalam Tiger Reserve, Southern India M. Sathya, S. Jayakumar Environmental Informatics and Spatial Modeling Lab, Department of Ecology and Environmental Sciences, School of Life Sciences, Pondicherry University, Puducherry 605014, India E-mail: [email protected] Received 28 December 2016; Accepted 5 February 2017; Published online 1 June 2017 Abstract Tree species inventory was carried out in five forest types of Sathyamangalam Tiger Reserve (STR). The forest type was divided into homogenous vegetation strata (HVS) based on the altitude, temperature, precipitation and forest types. A total of 8 ha area was sampled using 0.1 ha (20m 50m) plot and all tree species ≥ 1cm girth at breast height (gbh) within the plot were enumerated. In all, 4614 individuals were recorded that belonged to 122 species representing 90 genera and 39 families. Fabaceae, Euphorbiaceae, Rubiaceae, and Combretaceae were the species-rich families. The mean stand density of STR was 577 ha-1, but it varied from 180 ha-1 to 779 ha-1. Similarly, the mean basal area of the STR was 14.51 m2ha-1 which ranged between 8.41 m2 ha-1 and 26.96 m2 ha-1. The stem count was low at the lowest girth class (1-10 cm gbh) and high at 20-30 cm gbh in all the forest types. Anogeissus latifolia was the dominant species in the semi- evergreen and deciduous forest types while Chloroxylon swietenia was dominant in the thorn forest. -

Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt
plants Article Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt Rania A. Hassan * and Rim S. Hamdy Botany and Microbiology Department, Faculty of Science, Cairo University, Giza 12613, Egypt; [email protected] * Correspondence: [email protected] Abstract: For the first time, an updated checklist of Acacia, Senegalia and Vachellia species in Egypt is provided, focusing on the exotic species. Taking into consideration the retypification of genus Acacia ratified at the Melbourne International Botanical Congress (IBC, 2011), a process of reclassification has taken place worldwide in recent years. The review of Acacia and its segregates in Egypt became necessary in light of the available information cited in classical works during the last century. In Egypt, various taxa formerly placed in Acacia s.l., have been transferred to Acacia s.s., Acaciella, Senegalia, Parasenegalia and Vachellia. The present study is a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera. This study recorded 144 taxa (125 species and 19 infraspecific taxa). Only 14 taxa (four species and 10 infraspecific taxa) are indigenous to Egypt (included now under Senegalia and Vachellia). The other 130 taxa had been introduced to Egypt during the last century. Out of the 130 taxa, 79 taxa have been recorded in literature. The focus of this study is the remaining 51 exotic taxa that have been traced as living species in Egyptian gardens or as herbarium specimens in Egyptian herbaria. The studied exotic taxa are accommodated under Acacia s.s. (24 taxa), Senegalia (14 taxa) and Vachellia (13 taxa). -

Comparison of Growth Rings of Dichrostachys Cinerea and Senegalia Mellifera Along a Rainfall Gradient: Implications for Bush Encroachment in a Changing Climate
COMPARISON OF GROWTH RINGS OF DICHROSTACHYS CINEREA AND SENEGALIA MELLIFERA ALONG A RAINFALL GRADIENT: IMPLICATIONS FOR BUSH ENCROACHMENT IN A CHANGING CLIMATE A THESIS SUBMITED IN FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE (BY THESIS) OF THE UNIVERSITY OF NAMIBIA BY AANSBERT KUDUMO MUSIMBA (201142082) APRIL 2020 MAIN SUPERVISOR: PROF I.MAPAURE (UNIVERSITY OF NAMIBIA) CO-SUPERVISORS: PROF B.S.MAPANI AND DR R.N.SHIKANGALAH (UNIVERSITY OF NAMIBIA) ABSTRACT Tree ring studies, known as dendrochronology, have been an important tool for studying climate variations since the beginning of 1900s. This is because the information preserved in tree rings of most tree species for many years serves as environmental archives for both abiotic and biotic factors, tools that can be used to monitor climate changes. This study was the first to compare the growth rings of Dichrostachys cinerea and Senegalia mellifera along a rainfall gradient to infer implications for bush encroachment in a changing climate. Rainfall gradient in this study was defined by three study sites namely; 1) John Alphons Pandeni Research Station (600 mm); 2) Farm Onyoka (450 mm) and 3) Farm Ebenhaezer (250 mm). Stem discs of different sizes of the two species were sampled from each site and polished for dendrochronological study. The growth rings of D. cinerea trees were substantially influenced by the amounts of site rainfall, but the growth rings of S. mellifera trees were not influenced by site rainfall. Therefore, D. cinerea is a better sensor and indicator of rainfall variability and climate shifts than S. mellifera, which tolerates dry climates as much as the wet seasons. -
The Rothschild's Giraffe As a Potential Biological Controller of Invasive Native Acacia Species in Lake Mburo National Park, Uganda
Master’s Thesis 2018 60 ECTS Faculty of Environmental Sciences and Natural Resource Management Stein R.

Second, I would like to thank Jonas, my fellow student, for keeping me company in Uganda while we trekked after giraffes. Special thanks to Fred Matovu, our field assistant and protector from angry buffaloes. Thank you to Rose and everyone at the CEC for providing us with shelter, food, and ever-lasting memories. My family, thank you for enduring me all these years and for all the years to come. I would also like to acknowledge Ugandan Wildlife Authority for granting me permission to conduct research in Lake Mburo National Park and NMBU for providing funding for my plane tickets. Linn Williams i ii Abstract Shrub and woody encroachment can have serious ecological impacts and is an increasingly common problem in many ecosystems, from the African savanna to the Arctic. Lake Mburo National Park in Uganda is experiencing severe woody encroachment of the native invasive Acacia species. In 2015, 15 Rothschild’s giraffes (Giraffa camelopardalis rothschildi) were translocated to Lake Mburo as both a conservation effort to expand the range of the endangered giraffe subspecies and as part of a long-term project to control the encroachment of Acacia in the park. -
Phylogenetic Position and Revised Classification of Acacia S.L. (Fabaceae: Mimosoideae) in Africa, Including New Combinations in Vachellia and Senegalia

Botannical Journal of the Linnean Society, 172(4): 500 – 523. http://dx.doi.org/10.1111/boj.12047 Phylogenetic position and revised classification of Acacia s.l. (Fabaceae: Mimosoideae) in Africa, including new combinations in Vachellia and Senegalia Bruce Kyalangalilwa, James S. Boatwright, Barnabas H. Daru, Olivier Maurin and Michelle van der Bank Abstract Previous phylogenetic studies have indicated that Acacia Miller s.l. is polyphyletic and in need of reclassification. A proposal to conserve the name Acacia for the larger Australian contingent of the genus (formerly subgenus Phyllodineae) resulted in the retypification of the genus with the Australian A. penninervis. However, Acacia s.l. comprises at least four additional distinct clades or genera, some still requiring formal taxonomic transfer of species. These include Vachellia (formerly subgenus Acacia), Senegalia (formerly subgenus Aculeiferum), Acaciella (formerly subgenus Aculeiferum section Filicinae) and Mariosousa (formerly the A. coulteri group). In light of this fragmentation of Acacia s.l., there is a need to assess relationships of the non-Australian taxa. A molecular phylogenetic study of Acacia s.l and close relatives occurring in Africa was conducted using sequence data from matK/trnK, trnL-trnF and psbA-trnH with the aim of determining the placement of the African species in the new generic system. The results reinforce the inevitability of recognizing segregate genera for Acacia s.l. and new combinations for the African species in Senegalia and Vachellia are formalized. -

This study, conducted at a permanent site in central Zambia, aimed at determining the effects of seed scarification on seedling emergence and survival and growth and longevity of Senegalia polyacantha, a fast growing and nitrogen-fixing species that is widely distributed in Sub-Saharan Africa. Seedling emergence from scarified and untreated seeds was monitored and first-year survival assessed. Enrichment planting with nursery transplants and direct sowing of scarified seed was undertaken and the survival and growth of planted and non- planted trees monitored for 17 years. -
Biodiversité Végétale De Parcs À Résidus Miniers Restaurés Par Reboisement Et Application D’Amendements Au Québec, Canada
Biodiversité végétale de parcs à résidus miniers restaurés par reboisement et application d’amendements au Québec, Canada Par Alyson Gagnon Mémoire présenté à l’Université du Québec à Chicoutimi en vue de l’obtention du grade de maîtrise en ressources renouvelables Québec, Canada © Alyson Gagnon, 2020 ii RÉSUMÉ Les activités minières génèrent des résidus lors du procédé de concentration du minerai, ce qui résulte en de nombreux parcs à résidus miniers au Québec, Canada. Selon la loi sur les mines, une remise en végétation minimale avec des plantes herbacées ou des arbustes est requise pour restaurer les parcs à résidus miniers. Une hypothèse est que la restauration des résidus miniers en utilisant des espèces ligneuses et des amendements organiques pourrait établir une plus grande diversité de plantes comparativement au cours normal des affaires consistant à une mise en végétation minimale avec des poacées. Des designs expérimentaux en blocs et tiroirs ont été établis sur les parcs à résidus miniers du Mont-Wright (mine de fer, 52°46’N, 67°20’O) en 2015 et à St-Honoré (mine de niobium, 48°32’N, 71°08'O) en 2012 au Québec. L’objectif était de déterminer parmi les scénarios de restauration testés -incluant la combinaison d’amendements organiques (biosolides de papetières, fumier de poulet et humus forestier) et des plantations - laquelle résultait en une biodiversité végétale supérieure sur les deux sites considérant leur contexte climatique. Les résultats montrent qu’à St-Honoré, les biosolides de papetière combinée à l’humus forestier ont augmenté le pourcentage total de recouvrement de végétation, mais ont diminué l’équitabilité et la diversité.
