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. -

Herbarium Soutpansbergensis, P.O. Box 1734, Makhado, 0920. Abstract The Major Vegetation Types and plant communities of the Soutpansberg Centre of Endemism are described in detail with special reference to the Soutpansberg Conservancy and the Blouberg Nature Reserve. Phytosociological data from 466 sample plots were ordinated using a Detrended Correspondence Analysis (DECORANA) and classified using Two–way Indicator Species Analysis (TWINSPAN). The resulting classification was further refined with table–sorting procedures based on the Braun–Blanquet floristic–sociological approach of vegetation classification using MEGATAB. Eight Major Vegetation Types were identified and described as Eragrostis lehmanniana var. lehmanniana–Sclerocarya birrea subsp. caffra BNR Northern Plains Bushveld, Euclea divinorum–Acacia tortilis BNR Southern Plains Bushveld, Englerophytum magalismontanum–Combretum molle BNR Mountain Bushveld, Adansonia digitata–Acacia nigrescens Soutpansberg Arid Northern Bushveld, Catha edulis–Flueggia virosa Soutpansberg Moist Mountain Thickets, Diplorhynchus condylocarpon–Burkea africana Soutpansberg Leached Sandveld, Rhus rigida var. rigida–Rhus magalismontanum subsp. coddii Soutpansberg Mistbelt Vegetation and Xymalos monospora–Rhus chirendensis Soutpansberg Forest Vegetation. 26 Introduction The Soutpansberg Conservancy (SC) and the Blouberg Nature Reserve (BNR) reveal extremely rich diversities of plant communities relative to the sizes of these conservation areas (Van Wyk & Smith 2001). -

The Herpetofauna of the Cubango, Cuito, and Lower Cuando River Catchments of South-Eastern Angola
Official journal website: Amphibian & Reptile Conservation amphibian-reptile-conservation.org 10(2) [Special Section]: 6–36 (e126). The herpetofauna of the Cubango, Cuito, and lower Cuando river catchments of south-eastern Angola 1,2,*Werner Conradie, 2Roger Bills, and 1,3William R. Branch 1Port Elizabeth Museum (Bayworld), P.O. Box 13147, Humewood 6013, SOUTH AFRICA 2South African Institute for Aquatic Bio- diversity, P/Bag 1015, Grahamstown 6140, SOUTH AFRICA 3Research Associate, Department of Zoology, P O Box 77000, Nelson Mandela Metropolitan University, Port Elizabeth 6031, SOUTH AFRICA Abstract.—Angola’s herpetofauna has been neglected for many years, but recent surveys have revealed unknown diversity and a consequent increase in the number of species recorded for the country. Most historical Angola surveys focused on the north-eastern and south-western parts of the country, with the south-east, now comprising the Kuando-Kubango Province, neglected. To address this gap a series of rapid biodiversity surveys of the upper Cubango-Okavango basin were conducted from 2012‒2015. This report presents the results of these surveys, together with a herpetological checklist of current and historical records for the Angolan drainage of the Cubango, Cuito, and Cuando Rivers. In summary 111 species are known from the region, comprising 38 snakes, 32 lizards, five chelonians, a single crocodile and 34 amphibians. The Cubango is the most western catchment and has the greatest herpetofaunal diversity (54 species). This is a reflection of both its easier access, and thus greatest number of historical records, and also the greater habitat and topographical diversity associated with the rocky headwaters. -
Os Répteis De Angola: História, Diversidade, Endemismo E Hotspots
CAPÍTULO 13 OS RÉPTEIS DE ANGOLA: HISTÓRIA, DIVERSIDADE, ENDEMISMO E HOTSPOTS William R. Branch1,2, Pedro Vaz Pinto3,4, Ninda Baptista1,4,5 e Werner Conradie1,6,7 Resumo O estado actual do conhecimento sobre a diversidade dos répteis de Angola é aqui tratada no contexto da história da investigação herpe‑ tológica no país. A diversidade de répteis é comparada com a diversidade conhecida em regiões adjacentes de modo a permitir esclarecer questões taxonómicas e padrões biogeográficos. No final do século xix, mais de 67% dos répteis angolanos encontravam‑se descritos. Os estudos estag‑ naram durante o século seguinte, mas aumentaram na última década. Actualmente, são conhecidos pelo menos 278 répteis, mas foram feitas numerosas novas descobertas durante levantamentos recentes e muitas espécies novas aguardam descrição. Embora a diversidade dos lagartos e das cobras seja praticamente idêntica, a maioria das novas descobertas verifica‑se nos lagartos, particularmente nas osgas e lacertídeos. Destacam‑ ‑se aqui os répteis angolanos mal conhecidos e outros de regiões adjacentes que possam ocorrer no país. A maioria dos répteis endémicos angolanos é constituída por lagartos e encontra ‑se associada à escarpa e à região árida do Sudoeste. Está em curso a identificação de hotspots de diversidade de 1 National Geographic Okavango Wilderness Project, Wild Bird Trust, South Africa 2 Research Associate, Department of Zoology, P.O.

These include the declaration of “Bioregions” and the publication of “Bioregional Plans”. Bioregional plans are usually an output of a systematic spatial conservation assessment of a region. They identify areas of conservation priority, and constraints and opportunities for implementation of the plan. The precursor to a Bioregional Plan is a Biodiversity Sector Plan (BSP), which is the official reference for biodiversity priorities to be taken into account in land-use planning and decision-making by all sectors within the District Municipality. The overall aim is to avoid the loss of natural habitat in Critical Biodiversity Areas (CBAs) and prevent the degradation of Ecological Support Areas (ESAs), while encouraging sustainable development in Other Natural Areas.
