  • The Potential of Agroforestry in the Conservation of High Value Indigenous Trees: a Case Study of Umzimvubu District, Eastern Cape
    THE POTENTIAL OF AGROFORESTRY IN THE CONSERVATION OF HIGH VALUE INDIGENOUS TREES: A CASE STUDY OF UMZIMVUBU DISTRICT, EASTERN CAPE. SUPERVISOR: PROF. MIKE J. LAWES (FOREST BIODIVERSITY PROGRAMME) MICHAEL O. MUKOLWE MASTERS PROGRAMME IN ENVIRONMENT AND DEVELOPMENT SCHOOL OF ENVIRONMENT AND DEVELOPMENT UNIVERSITY OF NATAL PIETERMARITZBURG JULY 1999 This project was carried out within the Forest Biodiversity Programme School of Botany and Zoology University of Natal, Pietermaritzburg BiODiVERSiTY PROGRAMME UNIVERSITY OF NATAL DEDICATION This work dedicated to Messrs. Toshihiro Shima and Seiichi Mishima, and to my beloved wife Anne Florence Asiko and children Marion Akinyi, Fabian Omondi and Stephen Ochieng "Stevo". 11 ABSTRACT South Africa is not well endowed with indigenous forests which are now known to be degraded and declining at unknown rates. This constitutes a direct threat to quality oflife ofthe resource-poor rural households who directly depend on them and to ecological integrity. It is also recognised that the declining tree resources, particularly the high value indigenous tree species, are increasingly threatened by a number ofgrowing subsistence demands. This emphasised the need to cultivate and conserve high-value tree species such as Englerophytum natalense, Ptaeroxylon obliquum and Millettia grandis on-farm in Umzimvubu District. Agroforestry is recognised as a viable option for optimising land productivity, reducing pressure on the indigenous forests, ensuring a sustainable supply ofdesired tree products and services and improving the quality oflife ofthe resource-poor rural households. This Thesis examines whether agroforestry in Umzimvubu District and similar areas ofSouth Africa has the potential for addressing these needs. It recognises that for successful initiation, implementation and adoption, agroforestry should be considered at two levels, namely, household and institutional.

For most groups however, methodological protocols are still missing. Here Gene capture we identified531 monocopy genes and 227 Short Tandem Repeats (STR) markers and tested them on Sapotaceae STR using target capture and NGS. The probes were designed using two genome skimming samples from Capur­ Phylogenetics odendron delphinense and Bemangidia lowryi, both from the Tseboneae tribe, as well as the published Manilkara Population genetics Species tree zapota transcriptome from the Sapotoideae tribe. We combined our probes with 261 additional ones previously Tropical trees published and designed for the entire angiosperm group. On a total of 792 low-copy genes, 638 showed no signs of paralogy and were used to build a phylogeny of the family with 231 individuals from all main lineages.

  • The Phytogeography of Moist Forests Across Eastern Zimbabwe
    Plant Ecology and Evolution 154 (2): 192–200, 2021 https://doi.org/10.5091/plecevo.2021.1814 RESEARCH ARTICLE The phytogeography of moist forests across Eastern Zimbabwe Jonathan R. Timberlake1,*, Françoise Dowsett-Lemaire2 & Tom Müller3 1Biodiversity Foundation for Africa, East Dean, East Sussex, UK 2Le Pouget, F-30440, Sumène, France 3Herne Bay, Kent, UK *Corresponding author: [email protected] Background and aims – During the 1970s, a comprehensive survey of moist forest areas across Zimbabwe’s Eastern Highlands was carried out, from Nyanga in the north to Chirinda Forest in the south. All tree stems 8 cm diameter or greater in both canopy and sub-canopy layers were measured in 176 quarter-hectare plots, and plots were then classified into 12 altitude-related forest types. The aim of the present study is to categorise the woody species recorded in these plots in terms of their chorological status. The findings are compared to similar analyses from moist forests across Malawi. Material and methods – All tree species recorded during the initial survey were listed and placed into 12 described chorological (phytogeographical) categories based on their continental distribution. Their occurrence across the 12 previously described forest types is given. Key results and conclusions – A total of 211 tree species was recorded from 176 plots. Most species (86, or 40.8%) are Afromontane endemics or near-endemics, while 48 species (22.7%) are Guineo-Congolian linking, 31 (14.7%) are Eastern endemic or near-endemics, and 16 (7.6%) are sub-Afromontane endemics or near-endemics. The remainder comprise African linking and Zambezian species.

PhytoKeys 175: 151–174. https://doi.org/10.3897/phytokeys.175.61467 Abstract Covering 560.14 hectares in the south-east of Benin, the Ewe-Adakplame Relic Forest (EARF) is a micro- refugium that shows insular characteristics within the Dahomey Gap. It is probably one of the last rem- nants of tropical rain forest that would have survived the late Holocene dry period. Based on intensive field investigations through 25 plots (10 × 50 m size) and matching of herbarium specimens, a checklist of 185 species of vascular plant belonging to 54 families and 142 genera is presented for this forest. In ad- dition to the name for each taxon, we described the life form following Raunkiaer’s definitions, chorology as well as threats to habitat.
