Environmental authorisation was granted for Route Alternative 3. Eskom erroneously commenced with construction of Route Alternative 1 (their preferred route), for which they did not have an environmental authorisation. The Environmental Control Officer (ECO) stopped work on the line but only after a substantial portion of the unauthorised section had been built. GIBB (Pty) Ltd. is currently undertaking a Section 24G application to apply for authorisation for Route Alternative 1. To reduce the environmental impacts of Route Alternative 1, GIBB and Eskom have proposed some deviations to the power line Route 1 (which is now Route 4). These deviations were not assessed as part of the basic assessment process and so specialist studies need to be undertaken for these sections and assessed equally against all alternatives. An Avifauna and Biodiversity Report was undertaken by GIBB for the original Basic Assessment process. As part of the section 24G process GIBB requires more in-depth specialist studies to be undertaken in relation to avifauna and biodiversity. Indwe Environmental Consulting in association with Wildskies (Pty) Ltd. was subsequently appointed to undertake revised avifauna and biodiversity study. The biodiversity assessment comprised a desktop study using systematic biodiversity conservation planning outputs and data. In addition, a baseline survey to ground-truth the desktop analysis was conducted along the proposed power line route alternatives. In predicting the avifaunal impacts of a proposed power line on birds, a combination of science, field experience and common sense was required and was applied accordingly. The study area is located within the Gariep Municipality of the Eastern Cape Province. The Gariep Municipality is situated in the West of the Joe Gqabi District Municipality and South of the Orange River, which separates the municipality from the Northern Cape and Free State Provinces. The proposed 132kV power line will cover a distance of approximately 90 kilometres in a South Easterly direction from the Ruigtevallei substation, approximately 35 kilometres North West of Venterstad, to the Dreunberg substation. From a biodiversity conservation perspective the proposed power line crosses areas of high biodiversity conservation importance being protected areas, National Protected Area Expansion Areas, Critical Biodiversity Areas and Important Bird Areas. Despite this, no critically endangered ecosystems occur in the area. Two dominant vegetation types dominate the study area and both of these are classified as Least Threatened vegetation types in terms of the VEGMAP conservation priority classification. A number of small to large mammals of conservation significance are known to occur in the study area but are not considered to be at medium to high risk as a result of the proposed development. In terms of avifauna, a fairly wide diversity of species (approximately 280 species) could be found in the broader area within which this project falls. The area is relatively undisturbed by human activities currently, crop agriculture being restricted to localized areas, and the remainder being used for extensive livestock farming. This means that the area is important to a number of Red Listed bird species which can co-exist with farming activities in the area fairly comfortably. These include raptors, such as the Verreaux‟s Eagle (Aquila verreauxii) and various smaller buzzards, kestrels and falcons; and large terrestrial bird species, most important of which is the Blue Crane (Anthropoides paradiseus). The site is also comprised of both grassy and Karoo like vegetation elements, meaning that a broader diversity of bird species can utilise the area. An example of this is that both Blue (Eupodotis caerulescens) (a grassland specialist) and Karoo (Eupodotis vigorsii) (a shrubby Karoo specialist) Korhaans occur in the area. Priority bird species include Kori Bustard, Ludwig’s Bustard, Blue Crane, Grey Crowned Crane, Maccoa Duck, Martial Eagle, Tawny Eagle, Verreaux’s Eagle, Lanner Flacon, Peregrine Falcon, Greater Flamingo, Black Harrier, Karoo Korhaan, Southern Black Korhaan, Melodious Lark, African Marsh-Harrier, Greater Painted-snipe, African Rock Pipit, Secretarybird, Abdim’s Stork, Black Stork, Yellow-billed Stork, White Stork and Cape Vulture.
