This report presents the findings of the fauna and flora baseline assessment and the information gathered in this report will be used within the Bankable Feasability Study. The fauna and flora baseline assessment will provide a baseline condition of the study site, whereby an understanding of its current state will aid to facilitate the assessment of the needs of the potential changes the mine may create. This will help identify where changes to current mine plans are required and where additional expense may be required. The objectives of this study were to characterise the fauna and flora environment from a desktop level assessment, and to supplement this information with a single field visit. Thereafter, to establish the significance of the impact of the construction and operation phases associated with the proposed mine and associated infrastructure on the fauna and flora in the area of interest and to investigate any potential threats to the proposed project. The vegetation was found to be relatively uniform. Differing soil types due to topography and water accumulation (wetlands and drainange lines) appear to be the dominant factors in determining the vegetation variation. Land use has a major influence on the state of the vegetation. Natural vegetation has largely been removed for cultivation purposes. Over utilisation primarily in the form of grazing by domestic livestock will manifest itself in the occurrence of sparsely vegetated areas. From the results of the desktop work it was concluded that the study area is situated within Central Free State grassland, Winburg Grassy Shrubland and the Vaal-Vet Sandy Grassland (Mucina & Rutherford 2006). The Vaal-Vet Sandy Grassland vegetation type is considered to be Endangered, the Central Free State grassland as Vulnerable and Winburg Grassy Shrubland as least concern. Nationally, all three vegetation types were altered primarily by cultivation historically and at present. During the field visit, a brief screening of the habitat types were conducted in order to identify any animal species that might be present.The result of this was seven mammal species encountered in the game camp, and one species in the project area, not in the game camp. None of these species are officially protected. In conclusion, the areas investigated were differentiated from one another primarily through management measures employed and presence of water, whereby seasonally wet areas were excluded from agricultural activities due to unsuitable soil. Through the construction of the mine and its associated infrastructure the management and water availability through change in land use will be affected to a large extent. However, following the prescribed guidelines and mitigation measures set forth in this document an attempt will be made to minimise the impacts. Recommendations include: iv FLORA AND FAUNA BASELINE ASSESSMENT FOR A FEASIBILITY STUDY FOR THE PROPOSED VENTERSBURG MINE GOL1675 ■ Adherence to the mitigation measures as stipulated in the Impact Assessement; ■ The wetland areas and drainage lines must be avoided during construction and operation. ■ A specialist flora study to be conducted ■ A specialist mammal study to be conducted; ■ A specialist avifauna study to be conducted; ■ A specialist reptile study to be conducted; ■ A specialist amphibian study to be conducted; ■ Rehabilitation of areas should occur concurrent to mining activity; ■ A nursery is recommended which will serve to propagate indigenous species; ■ The footprint of the mine should be limited as much as possible; ■ Alien plants must be identified and removed throughout the construction, operation and decommissioning phases, design a specialist alien plant monitoring plan; v FLORA AND FAUNA BASELINE ASSESSMENT FOR A FEASIBILITY STUDY FOR THE PROPOSED VENTERSBURG MINE GOL1675 LIST OF ACRONYMS BFS Bankable-feasibility study CARA Conservation of Agricultural Resources Act (No 43 of 1983) Convention on International Trade in Endangered Species of Wild Fauna CITES and Flora DEAT Department of Environmental Affairs and Tourism ESIA Environmental and Social Impact Assessment EMP Environmental Management Plans GIS Geographic Information System Gold One Gold One Africa Limited IUCN International Union for the Conservation of Nature MBP Mpumalanga Parks Board NEMBA National Environmental Management: Biodiversity Act (No 10 of 2004) NSBA National Spatial Biodiversity Assessment PCD Pollution Control Dam POSA Plants of South Africa QDSG Quarter Degree Square Grid RDB Red Data Books Rob Roberts Birds Reference SABCA South African Butterfly Conservation Assessment SANBI South African National Biodiversity Institute SIBIS Sanbi’s Integrated Biodiversity Information System UV Ultra Violet TSF Tailings Storage Facility vi FLORA AND FAUNA BASELINE ASSESSMENT FOR A FEASIBILITY STUDY FOR THE PROPOSED VENTERSBURG MINE GOL1675 TABLE OF CONTENTS 1 INTRODUCTION .............................................................................................................. 1 2 TERMS OF REFERENCE ................................................................................................ 1 3 STUDY AREA ................................................................................................................... 2 4 METHODOLOGY .............................................................................................................. 4 4.1 Database review ..................................................................................................... 5 4.2 Maps and aerial photography review....................................................................... 5 4.2.1 Legislation ....................................................................................................... 5 4.2.2 Impact assessment .......................................................................................... 7 5 EXPERTISE OF THE SPECIALISTS ............................................................................... 9 6 RESULTS AND DISCUSSIONS ..................................................................................... 10 6.1 Flora ..................................................................................................................... 10 6.1.1 National Spatial Biodiversity Assessment ...................................................... 10 6.1.2 Description of vegetation type ........................................................................ 15 6.1.3 Central Free State Grassland ........................................................................ 18 6.1.4 Winburg Grassy Shrubland ............................................................................ 19 6.1.5 Vaal-Vet Sandy Grassland ............................................................................. 20 6.1.6 Plants of Conservation significance that could occur in the area .................... 21 6.2 Fauna ................................................................................................................... 22 6.2.1 Mammals ....................................................................................................... 22 6.2.2 Birds (Avifaina) .............................................................................................. 23 6.2.3 Reptiles .......................................................................................................... 26 6.2.4 Amphibians ...................................................................................................

  • ECOLOGICAL HABITAT ASSESSMENT for the PROPOSED 26Km 132Kv KINGBIRD LINE from the GUMENI SUBSTATION to the BOSLOOP SUBSTATIO
    ECOLOGICAL HABITAT ASSESSMENT FOR THE PROPOSED 26km 132kV KINGBIRD LINE FROM THE GUMENI SUBSTATION TO THE BOSLOOP SUBSTATION, ESKOM DISTRIBUTION DIVISION, NORTHERN REGION; MPUMALANGA PROVINCE Compiled for: SSI ENGINEERS & ENVIRONMENTAL CONSULTANTS BY: Mr C.L.COOK (MSc. Zool. U.P) Pr.Sci.Nat. 400084/08 Zoological Consultant: Specialist Herpetological Consultant Cell No. 082 688 9585 [email protected] SUBMITTED: 24th OCTOBER 2011 Ecological Survey for Gumeni to Bosloop132kV Kingbird Line 1 1. BACKGROUND INFORMATION Eskom Transmission is responsible for providing a high quality supply of electricity to meet the ever increasing needs of its end users. As a result, its infrastructure of power lines and substations are continuingly being established and expanded upon to support annual load growth. Eskom is planning to build a new 132kV Kingbird distribution line from the recently constructed Gumeni Substation to the south of Machadadorp to the existing Bosloop Substation. The study area is located in the Northern Mpumalanga Lowveld region. The powerline being considered for the project falls within rural areas, largely characterised by intensive commercial agricultural and pastoral land uses. The area is situated close to the small mining town of Machadadorp approximately 17km to the north, with Nelspruit situated approximately 75km to the northwest. There are two main roads that allow general access to the study area and these are R541 and the R36. The need for ESKOM’s proposed development has been identified by the low voltage service experienced in the 132kV ring supplied from Witkloof substation due to the loss of either the Witkloof-Holnek 132kV line or Witkloof-Wintershoek 132kV line voltages during the transmission and distribution.

  • Biogeography of Mammals in SE Asia: Estimates of Rates of Colonization, Extinction and Speciation
    Biological Journal oflhe Linnean Sociely (1986), 28, 127-165. With 8 figures Biogeography of mammals in SE Asia: estimates of rates of colonization, extinction and speciation LAWRENCE R. HEANEY Museum of <oology and Division of Biological Sciences, University of Michigan, Ann Arbor, Michigan 48109, U.S.A. Accepted for publication I4 February 1986 Four categories of islands in SE Asia may be identified on the basis of their histories of landbridge connections. Those islands on the shallow, continental Sunda Shelf were joined to the Asian mainland by a broad landbridge during the late Pleistocene; other islands were connected to the Sunda Shelf by a middle Pleistocene landbridge; some were parts of larger oceanic islands; and others remained as isolated oceanic islands. The limits of late Pleistocene islands, defined by the 120 ni bathymetric line, are highly concordant with the limits of faunal regions. Faunal variation among non-volant mammals is high between faunal regions and low within the faunal regions; endcmism of faunal regions characteristically exceeds 70%. Small and geologically young oceanic islands are depauperate; larger and older islands are more species-rich. The number of endemic species is correlated with island area; however, continental shelf islands less than 125000 km2 do not have endemic species, whereas isolated oceanic islands as small as 47 km2 often have endemic species. Geologirally old oceanic islands have many endemic species, whereas young oceanic islands have few endemic species. Colonization across sea channels that were 5-25 km wide during the Pleistocene has been low, with a rate of about 1-2/500000 years.

In lizards particularly, species with more robust crania generally feed on harder prey items and possess a greater bite force, whereas those that prey on evasive prey typically have longer snouts. However, the link between dietary niche breadth, morphology, and performance has not been explicitly investigated in lizards. The southern African genus Nucras was used to investigate this link because the species exhibit differing niche breadth values and dietary compositions. A phylogeny for the genus was established using mitochondrial and nuclear markers, and morphological clusters were identified. Dietary data of five Nucras species, as reported previously, were used in correlation analyses between cranial shape (quantified using geometric morphometrics) and dietary niche breadth, and the proportion of hard prey taken and bite force capacity.

  • South Africa: Magoebaskloof and Kruger National Park Custom Tour Trip Report
    SOUTH AFRICA: MAGOEBASKLOOF AND KRUGER NATIONAL PARK CUSTOM TOUR TRIP REPORT 24 February – 2 March 2019 By Jason Boyce This Verreaux’s Eagle-Owl showed nicely one late afternoon, puffing up his throat and neck when calling www.birdingecotours.com [email protected] 2 | TRIP REPORT South Africa: Magoebaskloof and Kruger National Park February 2019 Overview It’s common knowledge that South Africa has very much to offer as a birding destination, and the memory of this trip echoes those sentiments. With an itinerary set in one of South Africa’s premier birding provinces, the Limpopo Province, we were getting ready for a birding extravaganza. The forests of Magoebaskloof would be our first stop, spending a day and a half in the area and targeting forest special after forest special as well as tricky range-restricted species such as Short-clawed Lark and Gurney’s Sugarbird. Afterwards we would descend the eastern escarpment and head into Kruger National Park, where we would make our way to the northern sections. These included Punda Maria, Pafuri, and the Makuleke Concession – a mouthwatering birding itinerary that was sure to deliver. A pair of Woodland Kingfishers in the fever tree forest along the Limpopo River Detailed Report Day 1, 24th February 2019 – Transfer to Magoebaskloof We set out from Johannesburg after breakfast on a clear Sunday morning. The drive to Polokwane took us just over three hours. A number of birds along the way started our trip list; these included Hadada Ibis, Yellow-billed Kite, Southern Black Flycatcher, Village Weaver, and a few brilliant European Bee-eaters.

  • Graphiurus Platyops – Rock Dormouse
    Graphiurus platyops – Rock Dormouse Assessment Rationale Listed as Least Concern as the species is widespread, and, although no field surveys have been conducted recently in most areas of its range, it is thought to be fairly common in suitable habitat (especially in the northern Photograph parts of its range). Recently (2007 and 2014), it has been recorded from Tswalu Kalahari Reserve in the Northern wanted Cape Province, significantly extending its known range westwards. There are not suspected to be any major threats as the species occupies inaccessible habitats not prone to transformation and there seems to be no reason to believe that the population is declining. More work is necessary to discern its distribution from other Graphiurus spp. and to vet museum specimens pertaining to both this species and Graphiurus rupicola. Regional Red List status (2016) Least Concern Regional population effects: Possible immigration from National Red List status (2004) Data Deficient areas where habitat is continuous into South Africa from Reasons for change Non-genuine change: Zimbabwe and Botswana, but the Swaziland New information subpopulation is isolated. Global Red List status (2016) Least Concern TOPS listing (NEMBA) (2007) None Distribution This species is patchily distributed in the northeastern CITES listing None savannahs of southern Africa (Monadjem et al. 2015), and Endemic No has been recorded from Zambia, southern Malawi, much of Zimbabwe, central Mozambique, eastern Botswana, This species of dormouse is, to a greater extent, northeastern South Africa and the highveld of Swaziland. It associated with rocky habitat when compared was previously thought to occur in central Botswana (de with the other species within this group.
