DIGBY WELLS ENVIRONMENTAL v www.digbywells.com Aquatic Biodiversity and Impact Assessment Report Proposed Dalyshope Coal Mining Project, Situated in the Magisterial District of Lephalale, Limpopo Province UCD6170 EXECUTIVE SUMMARY This study was commissioned by Universal Coal Development IV (Pty) Ltd on behalf of Anglo Operations Proprietary Limited to assess the baseline ecological state of the lotic aquatic ecosystems associated with the proposed Dalyshope Coal Mining Project. Digby Wells Environmental (hereafter Digby Wells) conducted an aquatic ecological state assessment in 2013/14 high and low-flow (dry and wet season) surveys for the proposed Dalyshope Coal Mine. The current survey therefore refers to the findings of the previous wet season assessment – wherein a flood was experienced – for comparison purposes. The project is located in the Lephalale area, Limpopo Province, and entails the establishment of a contractor operated, truck and shovel opencast mine producing approximately 2.4 million tonnes per annum (Mtpa) of thermal coal product for approximately five years. After five years, the mine will ramp up production to approximately 12 Mtpa of product for approximately 25 years from a single open pit (OC1), giving a total life of mine of 30 years. This document serves as the Aquatic Specialist Study for the proposed Project. The goal of the Aquatic Study was to describe the baseline conditions within the aquatic ecosystems associated with the Project and proposed surface infrastructure prior to the commencement of construction activities. Foreseeable aquatic-related impacts were also identified and appropriate mitigation measures were provided for the preservation of the assessed aquatic ecosystems. The main aquatic ecosystem of focus in the Aquatic Study is the Limpopo River (SQR A41E- 00126) wherein sampling was undertaken from the 12th to 14th February 2020. This watercourse drains from south-west along the north-western boundary of the Project Area. The Limpopo River is a transboundary resource shared with Botswana and Zimbabwe, flows in an easterly direction, into Mozambique and drains into the Indian Ocean. The Project Area lies in an endorheic region – an area that does not contribute to surface water flow to river systems – with several depression pans present within the Project’s boundary. Water drainage into the Limpopo from the project area can be limited to diffuse overland flow. The timing of the baseline aquatic survey coincided with the wet season for the Study Area. At the time of the survey, the Limpopo River system was in flood and had water levels exceeding the water table. Instream channels along the Limpopo system were too deep to sample without a boat, the presence of crocodiles and hippos presented a high risk as well. As such, these negatively affected the depth of sampling as suitable habitat for aquatic biota could not be accessed and sampling was limited to the marginal banks of the defined river channel where it was deemed safer to sample. This is reflected in the ecological health indices utilised during the baseline determination. Baseline Ecological Conditions Water quality results within the sampled Limpopo River reach were variable. The pH values recorded exhibited largely close to neutral, slightly alkaline conditions. Conductivity values and oxygen levels were predominantly low at all assessed sites. These were suspected to be DIGBY WELLS ENVIRONMENTAL vi www.digbywells.com Aquatic Biodiversity and Impact Assessment Report Proposed Dalyshope Coal Mining Project, Situated in the Magisterial District of Lephalale, Limpopo Province UCD6170 attributed to the flooding event at the time of the survey, i.e. a dilution effect causing lower levels of the parameters. None of the parameters recorded extreme levels, therefore were not expected to deter indigenous aquatic biota from colonisation and/or inhabiting the associated extent of the watercourse to a notable degree. In comparison to the 2014 wet season survey, only conductivity and dissolved oxygen levels differ at a single upstream site, most notably the conductivity levels. The relatively higher conductivity and dissolved oxygen levels were probably a result of increased turbidity and aeration caused by the high flows. Along the assessed Limpopo River reach, the ecological condition of the habitat was

  • Molecular Investigations of the Diversity of Freshwater Fishes Across Three Continents
    Molecular Investigations of the Diversity of Freshwater Fishes across Three Continents by Malorie M. Hayes A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 8, 2020 Keywords: Enteromius, Barbus, sub-Saharan Africa, phylogenetics, systematics, Pteronotropis, conservation genetics, Trichomycterus, Guyana Copyright 2020 by Malorie M. Hayes Approved by Jonathan W. Armbruster, Chair, Professor and Director Auburn University Museum of Natural History Department of Biological Sciences Jason E. Bond, Professor and Schlinger Chair in Insect Systematics University of California, Davis Scott R. Santos, Professor and Chair of the Department of Biological Sciences at Auburn University John P. Friel, Director of the Alabama Museum of Natural History Abstract Fishes are the most speciose vertebrates, and incredible diversity can be found within different groups of fish. Due to their physiological limitations, fish are confined to waters, and in freshwater fish, this is restricted to lakes, rivers, and streams. With a constrained habitat like a freshwater system, it can be expected that freshwater fish will show varying levels of diversity depending on a suite of characteristics. Within this dissertation, I examine the diversity of three fish groups: the speciose Enteromius of West Africa, the population genetic diversity of Pteronotropis euryzonus in Alabama and Georgia, and the unexpectedly species rich Trichomycterus from the Guyana highlands. I use molecular methods and geometric morphometrics to determine the systematics of the species and uncover the hidden diversity within their respective groups. When it comes to diversity, the small barbs of Africa are vastly understudied and require a taxonomic revision.

Approximately 25 Mℓ/day of fissure water flows into the underground workings of the defunct Blyvooruitzicht Mine, which spans a strike of 6 km along the boundary with AGA. If dewatering at the Old Blyvooruitzicht Shafts (#4, #5 & 6#) shafts were to cease, uncontrolled fissure water would report to the AGA operations, which would pose both a flood and safety risk of AGA personnel and the mining operations. This report provides a professional opinion regarding the anticipated terrestrial, wetland and aquatic impacts from this proposed project. Location The proposed water pipeline and associated infrastructure is located approximately 80 km west of Johannesburg. It originates at CWC 4#, approximately 3.3 km south east of Carletonville and ends at the North Boundary Dam (NBD) approximately 6 km south-south-west of Carletonville in Blyvooruitzicht, Merafong City Local Municipality, West Rand District Municipality in the Gauteng Province of South Africa.

Lake Tana is an isolated fresh-water system, because its only outflowing river, the Blue Nile, of which it is the source, drops over 40 m high waterfalls only 35 km from the lake. The carplike barbs in the lake are unique and show a wide variety of discrete, and consistent types, widely differing in 1) size and shape, 2) feeding behaviour, and 3) spatial distribution.

A total of 1307 fish were collected from the lake during the month of November, 2017. Water samples, sediment samples, 25 fish muscle tissues and its endoparasite, the cestode Ligula intestinalis were collected and heavy metal concentrations determined using the Thermal-electron atomic absorption spectrophotometer. The concentrations of these heavy metals in the sediment showed no signs of pollution. In the muscle tissues of the fish, As, Cr, Pb and Hg showed high levels with mean concentrations of 5.0696, 22.0854, 45.2108 and 1.5458 mg/ kg ww respectively. The Target hazard quotients of As, Cr, Pb and Hg obtained were 98.5066, 42.9138, 65.8863 and 90.1086 respectively, indicating a possible health risk associated with the consumption of the straightfin barb.
