Population trends of seabirds breeding in South Africa’s Eastern Cape and the possible influence of anthropogenic and environmental change. Marine Ornithology 37: 159–174. Eleven species of seabird breed in South Africa’s Eastern Cape Province. Numbers of African Penguin Spheniscus demersus and Cape Gannet Morus capensis in the province increased in the 20th century, but penguins decreased in the early 21st century. A recent eastward displacement of Sardine Sardinops sagax off South Africa increased the availability of this food source to gannets but did not benefit penguins, which have a shorter foraging range. Fishing and harbour developments may have influenced the recent decrease of penguins.

  • Palaeontological Impact Assessment: Desktop Study
    PALAEONTOLOGICAL IMPACT ASSESSMENT: DESKTOP STUDY Proposed construction of two filling stations adjacent to the N2, Zones 1 and 2 of the Coega IDZ, Nelson Mandela Bay Municipality, Eastern Cape Province John E. Almond PhD (Cantab.) Natura Viva cc, PO Box 12410 Mill Street, Cape Town 8010, RSA [email protected] April 2010 1. SUMMARY The two proposed filling station developments are located either side of the N2 in Zones 1 and 2 of the Coega IDZ, between St George’s Strand and Motherwell, Nelson Bay Municipality. Both development sites are underlain by limestone-rich shallow marine sediments of the Alexandria Formation (Algoa Group), with intermittent cover of pebbly residual weathering products (the so-called Bluewater Bay Formation). The Alexandria Formation has a high palaeontological sensitivity since it hosts a rich fossil marine biota of Miocene to Pliocene age that is dominated by molluscs and various other invertebrates, together with rare fish and (possibly) other vertebrate remains. Although much of the Alexandria Formation within the Coega IDZ has been altered by weathering and calcretization, seriously reducing its fossil content, the two filling station developments are situated close to an established fossil site (an abandoned limestone quarry) within this formation. Palaeontological mitigation is therefore recommended in both cases. Should thin sandstones and mudrocks of the Sundays River Formation beneath the Algoa Group limestone capping be exposed during deep excavations, these potentially fossil-rich sediments will also require palaeontological mitigation. Mitigation by a qualified palaeontologist should entail (a) the field examination of new excavations, (b) the recording of sedimentological and palaeontological data, (c) the judicious sampling of fossil material and (d) recommendations for any further action required to safeguard fossil heritage.

  • Algoa Bay Management Plan
    ALGOA BAY MANAGEMENT PLAN Vision Algoa Bay is a multi-use coastal zone that requires a proactive and practical management plan based on scientific integrity and stakeholder participation to ensure future sustainable development Prepared by: CLABBS Consortium c/o 36 River Road, Walmer, Port Elizabeth 6070 Tel: 041 581 2983 Fax: 041 581 2983 Email : [email protected] For: African Environmental Solutions P.O. Box 53577 Kenilworth 7745 The contributors cannot be held responsible for any damages whatsoever (including without limitation, damages for loss of trade or business profits, business interruption or any other pecuniary loss) arising out of the adoption of any scientific advice or recommended guidelines in this management plan DECEMBER 1999 EXECUTIVE SUMMARY Algoa Bay is a multi-use coastal zone with a variety of interest groups. Threats to and impacts on the environment will therefore affect both the commercial and the recreational interests in the area. This report outlines the rationale towards, and the development of, a management plan for Algoa Bay, for the marine environment below the spring high-water mark between Cape Recife and Woody Cape. The Algoa Bay Management Plan is a holistic document, drawing on previous environmental studies and has aimed to consolidate the ideas of all interested and affected parties. The plan has built on some previous public participation during previous environmental studies and has included some further consultation with management authorities locally and nationally (Port Elizabeth Municipality, University of Port Elizabeth, Portnet, Coega IA, Bay World and MCM). The development of the plan has defined critical issues and concentrated on these.

  • The Hydrogeology of the Uitenhage Artesian Basin with Reference to the Table Mountain Group Aquifer
    The hydrogeology of the Uitenhage Artesian Basin with reference to the Table Mountain Group Aquifer LGA Maclear SRK Consulting Engineers and Scientists, PO Box 21842, Port Elizabeth 6000, South Africa Abstract The Uitenhage Artesian Basin (UAB) lies in the Eastern Cape and is South Africa’s most important artesian groundwater basin, supplying approximately 1 400 Ml/yr (44 l/s) of water from springs for domestic use to Uitenhage, as well as supporting large citrus irrigation schemes. Groundwater from this basin has been extensively utilised from the early part of the 20th century, including periods of over-exploitation resulting in the declaration of a groundwater control area to limit abstraction to sustainable rates. The aquifer comprises fractured Table Mountain Group (TMG) sandstones confined in the eastern part of the basin by overlying Cretaceous siltstones and mudstones, resulting in artesian conditions. The Coega Fault is a major structural feature dividing the basin into separate systems, viz. the southern Swartkops Aquifer and the northern Coega Ridge Aquifer, that are hydrogeologically independent of each other. The Elands River syncline divides the Swartkops Aquifer further into the Kruisrivier and Bethelsdorp Units. Borehole yields commonly range from 5 to 10 l/s and the groundwater quality is excellent with low salinities. Water hardening, however, is required due to the acidic and corrosive nature of the groundwater, typical of other Table Mountain Group aquifers in South Africa. Using 14C data, the age of the groundwater in the basin ranges from 1 500 to 28 000 years with a calculated flow rate of 0.8 m/a.
