Basic Assessment for the Proposed Aggeneys 2 Solar Pv Facility and Associated Infrastructure BASIC ASSESSMENT FOR THE PROPOSED AGGENEYS 2 SOLAR PV FACILITY AND ASSOCIATED INFRASTRUCTURE: AVIFAUNAL SPECIALIST STUDY Red Lark Calendulauda burra PRODUCED FOR SAVANNAH ENVIRONMENTAL BY [email protected] April 2019 Avifaunal Specialist Report EXECUTIVE SUMMARY ABO Wind Aggeneys PV 2 (Pty) Ltd is proposing the establishment of a 100MW commercial solar photovoltaic (PV) facility and associated infrastructure, called Aggeneys 2, on the Remainder of the Farm Bloemhoek 61, situated in the Namakwa District Municipality in the Northern Cape Province near Aggeneys. As the site falls within the Springbok Renewable Energy Development Zone (REDZ), a Basic Assessment (BA) process is required for authorisation. Savannah Environmental has appointed 3Foxes Biodiversity Solutions to provide a specialist avifaunal EIA study of the project site as part of the required BA process. A full field assessment over two seasons as well as a desktop review of the available avifaunal information for the area was conducted in order to identify and characterise the avifaunal features of the project site. An approximate total of 105 bird species have been previously recorded within the broader study area, of which 54 species were observed during the site visit in winter (June 2018) and summer (March 2019). Eight (8) of these are red-listed as Threatened while a further four (4) are Near-threatened. One species, the Vulnerable Red Lark Calendulauda burra, is endemic to South Africa, while fourteen (14) other species are near-endemic. Twelve (12) species are listed as biome-restricted, and include a number of lark species in particular. The site is located near an Important Bird Area (IBA) known as Haramoep and Black Mountain Mine. This IBA is one of only a few sites that provides protection to the globally threatened Red Lark. The IBA also supports a number of other red-listed species, while it is also important for seasonally occurring nomadic larks. The Red Lark distribution on the site does not overlap with the development area and the field surveys indicate that it is strongly associated with the red dune system of the Koa River valley about 2km south of the development area. The expected impacts of Aggeneys 2 within the project site includes 1) habitat loss and fragmentation associated with the Bushmanland Arid Grassland habitat, 2) disturbance caused during the construction and maintenance phases, and 3) direct mortality of avifauna colliding with solar panels and possible entrapment along perimeter fencing. The species that will be the most negatively impacted by the proposed development include mostly small passerines, ground-dwelling non-passerines and large raptors and terrestrial birds that occasionally use the area for foraging. The impacts on the avifauna would normally be expected to be of medium significance, but due to the low frequency of occurrence of priority red-listed species and the wide distribution and nomadic movements of many of the near- endemics and biome-restricted species, the impacts are likely to be low and no high post- mitigation impacts are expected to occur. 2 Aggeneys 2 Avifaunal Specialist Report The primary mitigation measures required to reduce the potential impacts on priority species would include 1) restricting habitat destruction and disturbance to the footprint of the proposed development, 2) exclusion of the dune habitat with an adequate buffer zone to be avoided and excluded from any disturbance or future development, and 3) ensuring that perimeter fencing along the boundaries of the development are bird and wildlife friendly (especially for ground-dwelling species). Considering that the project site for Aggeneys 2 supports a typical Nama-Karoo bioregional avifaunal assemblage, and that there are no known breeding or roosting sites of red-listed priority species within 3 km of the site, and that most near-endemics and biome-restricted species have wide distribution ranges, there are no impacts associated with the development that are considered to be of high significance and which cannot be mitigated to a low acceptable level. Therefore, there are no fatal flaws from an avifaunal perspective that should prevent the development from proceeding. Cumulative impacts associated with the development may be of moderate concern due to increasing number of solar facility developments proposed for the broader Aggeneys area. Considering that the vegetation and avifauna that occur on the property are rather typical of the Nama-Karoo bioregion, the overall cumulative avifaunal impact of the development is, however, considered to be low, provided the development footprint for Aggeneys 2 remains restricted to the plains habitat of the Bushmanland Arid Grassland vegetation type. Impact statement The proposed site for Aggeneys 2 is considered to represent a broadly suitable environment for the location of the proposed solar PV facility. Considering that the study area supports a typical bioregional avifaunal assemblage within an extensive vegetation type, and that there are no known breeding or roosting sites of red-listed priority species within close proximity (<3 km), there are no impacts associated with the development that are considered to be of high residual significance and which cannot be mitigated to a low acceptable level. Consequently, the development can be supported from an avifaunal perspective. It is therefore the reasoned opinion of the specialist that Aggeneys 2 should be authorised, subject to the implementation of the recommended mitigation measures. 3 Aggeneys 2 Avifaunal Specialist Report CONTENTS Executive Summary....................................................................................................2 Contents .................................................................................................................4 Compliance with Appendix 6 of the 2014 EIA Regulations, as Amended .....................................5 Short CV/Summary of Expertise .....................................................................................6 Specialist Declaration 1 ...............................................................................................9 Specialist Declaration 2 .............................................................................................10 1 INTRODUCTION ............................................................................................11 1.1 Scope of Study ............................................................................................12 1.2 Relevant Aspects of the Development.............................................................13 2 METHODOLOGY ...........................................................................................15 2.1 Data Sourcing and Review ............................................................................15 2.2 Site Visit & Field Methodology........................................................................16 2.3 Sensitivity Mapping & Assessment..................................................................17 2.4 Sampling Limitations and Assumptions ...........................................................18 3 DESCRIPTION OF THE AFFECTED ENVIRONMENT- BASELINE ...............................19 3.1 Site Context & Avifaunal Microhabitats of the Site ............................................19 3.2 General Avifauna .........................................................................................21 3.3 Red-listed Species........................................................................................25 3.4 Current Baseline & Cumulative Impact............................................................29 3.5 Avian Sensitivity Assessment.........................................................................30 4 IDENTIFICATION & NATURE OF IMPACTS...........................................................32 4.1 Identification of Potential Impacts and Damaging Activities ...............................34 5 ASSESSMENT OF IMPACTS.............................................................................36 5.1 Aggeneys 2 .................................................................................................36 5.1.1 Planning & Construction Phase Impacts ....................................................37 5.1.2 Operational Phase Impacts......................................................................38 5.1.3 Decommissioning Phase Impacts .............................................................40 5.1.4 Cumulative Impacts ...............................................................................42 6 CONCLUSION & RECOMMENDATIONS ..............................................................43 7 ACTIVITIES FOR INCLUSION IN DRAFT EMPR .....................................................46 8 REFERENCES ..............................................................................................53 9 Annex 1.

  • Namibia & the Okavango
    Pel’s Fishing Owl - a pair was found on a wooded island south of Shakawe (Jan-Ake Alvarsson) NAMIBIA & THE OKAVANGO 21 SEPTEMBER – 8 OCTOBER 2017 LEADER: STEVE BRAINE For most of the country the previous three years drought had been broken and although too early for the mi- grants we did however do very well with birding generally. We searched and found all the near endemics as well as the endemic Dune Lark. Besides these we also had a new write-in for the trip! In the floodplains after observing a wonderful Pel’s Fishing Owl we travelled down a side channel of the Okavango River to look for Pygmy Geese, we were lucky and came across several pairs before reaching a dried-out floodplain. Four birds flew out of the reedbeds and looked rather different to the normal weavers of which there were many, a closer look at the two remaining birds revealed a beautiful pair of Cuckoo Finches. These we all enjoyed for a brief period before they followed the other birds which had now disappeared into the reedbeds. Very strong winds on three of the birding days made birding a huge challenge to say the least after not finding the rare and difficult Herero Chat we had to make alternate arrangements at another locality later in the trip. The entire tour from the Hosea Kutako International Airport outside the capital Windhoek and returning there nineteen days later delivered 375 species. Out of these, four birds were seen only by the leader, a further three species were heard but not seen.

  • The Karoo Birds Research and Conservation Project
    The Karoo Birds Research and Conservation Project Final Project Report based on fieldwork conducted through the Karoo south of the Orange River during 2017 and 2018 A BirdLife South Africa conservation project by Alan Lee and Dale Wright. Report by: Alan Lee January 2019 1 Summary The Karoo biome is a vast arid zone environment covering 26% of South Africa, as well as Namibia, and is home to 11 endemic bird species. The Karoo Birds Project was a BirdLife South Africa initiative run from 2017-2018, which aimed to provide a conservation assessment by obtaining data on population size, range and population trends primarily of the Karoo endemic bird species. This report was obtained through a point count and atlasing project across the Karoo region south of the Orange River, South Africa. This was partly run in conjunction with the Karoo BioGaps project. The South African National Biodiversity Institute’s (SANBI) Karoo BioGaps project aimed to gather foundational biodiversity data to support the impact assessments for Shale Gas and other infrastructure development projects in the Karoo basin. During 2017 and 2018 we conducted 2854 point counts across 150 pentads, mostly from end of July to October, largely corresponding to the late winter to early spring period. We found that avian species richness and bird abundance increased eastwards, mostly explained by increasing overall vegetation height, but accompanied by increasing grass cover and decreasing sand cover. In contrast, Karoo endemic bird species richness decreased eastwards, negatively correlated with increasing grass and acacia tree cover. Density and species richness were especially high around water locations and farmhouses, and we found that the presence of many species to be influenced by water, a surprising result for an arid environment.

PRESSEY, JAN SCHIPPER, WES SECHREST, SIMON N. STUART, LES G. UNDERHILL, ROBERT W. WALLER, MATTHEW E. J. WATTS, AND XIE YAN Protected areas are the single most important conservation tool. The global protected-area network has grown substantially in recent decades, now occupying 11.5% of Earth’s land surface, but such growth has not been strategically aimed at maximizing the coverage of global biodiversity. In a previous study, we demonstrated that the global network is far from complete, even for the representation of terrestrial vertebrate species. Here we present a first attempt to provide a global framework for the next step of strategically expanding the network to cover mammals, amphibians, freshwater turtles and tortoises, and globally threatened birds. We identify unprotected areas of the world that have remarkably high conservation value (irreplaceability) and are under serious threat. These areas concentrate overwhelmingly in tropical and subtropical moist forests, particularly on tropical mountains and islands. The expansion of the global protected-area network in these regions is urgently needed to prevent the loss of unique biodiversity. Keywords: conservation planning, conservation priorities, global gap analysis, irreplaceability, protected areas he in situ conservation of viable populations in the regions where protection is most lacking. This informa- Tnatural ecosystems is widely recognized as a fundamen- tion is needed to guide the strategic expansion of the network tal requirement for the maintenance of biodiversity (CBD and the effective allocation of scarce conservation resources 1992).

Introduction The Square Kilometre Array (SKA) is situated in the Nama Karoo, so only those bird species that occur in the Nama Karoo will be discussed here. The study area of the strategic environmental assessment (SEA) for the first phase of the SKA project (SKA1_MID) covers 153 Quarter Degree Grid Cells (QDGC)1, fairly well covered by participants in the Bird Atlas project in the late 1980s and early 1990s with lists of bird species for all 153 QDGC. Data for the 153 QDGC are a combination of the South African Bird Atlas Project data, museum specimen data and sight data (WRJD pers. obs.) and includes a recent bird list compiled by Etienne Marais. The avifauna of the Nama Karoo is not distinctive, and there are no families of birds endemic to the Karoo, but there are 25 species that are near-endemic to the region (Table 1). Only two species, Red Lark Calendulauda burra and Sclater's Lark Spizocorys sclateri, whose distribution ranges are almost entirely within the Nama Karoo, can be considered true endemics to the Nama Karoo.

  • Karoo Chat Is Paler and Has a White Rump
    182 Turdidae: thrushes, chats, robins and rockjumpers Karoo Chat is paler and has a white rump. However, these errors are not believed to have had a serious effect on the data. Habitat: Although its range overlaps greatly with other chats of the Karoo, its preferred habitat differs subtly from theirs. In contrast to the Sicklewinged Chat C. sinuata and the Anteating Chat Myrmecocichla formicivora, it is most common in the westerly, succulent-dominated parts of the Karoo, including the Little Karoo in the south. It prefers somewhat denser, taller scrub than the Tractrac Chat, and in northern Namibia it is altitudinally separated from that species, with the Tractrac occupying lowlands nearer the coast and the Karoo Chat occupying high ground further inland (Keith et al. 1992). The Karoo Chat can be found both on the flats and on broken ground, but is replaced in mountainous habitats by the Mountain Chat. It does not seek out human habitation like the Familiar Chat C. fami- liaris and it does not use the very open, bare ground and overgrazed and cultivated habitats favoured by the Capped Wheatear O. pileata. Movements: Although marked, the seasonal fluctuations in reporting rate are not thought to denote movements. It is more likely that a spring/summer drop in reporting rates is due to reduced activity in the summer heat and possibly a degree of secretiveness while breeding and during post- breeding moult. Breeding: It has a spring/summer breeding season with a peak September–November. The few records reported by Winterbottom (1968a) were July–October. Maclean (1993b) gave the breeding season as August–March with variation linked to rainfall.

  • THE BIOLOGY of the LARKS (ALAUDIDAE) of the KALAHARISANDVELD Department of Ecology and Systematics, Cornell University, Ithaca
    THE BIOLOGY OF THE LARKS (ALAUDIDAE) OF THE KALAHARISANDVELD G. L. MACLEAN Department of Ecology and Systematics, Cornell University, Ithaca, New York, U.S.A.· INTRODUCTION No family of passerine birds has shown as great an adaptive radiation in the arid regions of the Old World as have the larks. One species, the homed lark Eremophila alpestris, probably has the widest range of any passerine (excluding introduced species), having a circumpolar distribution with numerous subspecies, and even one in northern South America (Meinertz­ hagen 1954). Of the world's 76 species of larks (Peters 1960) 25 occur in South Mrica (McLachlan & Liversidge 1957) and of these, nine are found in the Kalahari sandveld. Eight of them are breeding species, while one, the red-capped lark Calandrella cinerea, is an irregular visitor in small numbers. It is therefore surprising to find that little biological work has been done on the South Mrican larks, although the systematists have argued long about the systematic pos~tion of museum skins (e.g. Macdonald 1952b, 1953, 1957; Verheyen 1958, 1959; White 1952, 1956a, b, c, 1957a, b, 1959a, b; Winterbottom 1962). Most of the biological work on larks has been done. in regions where only one, or at most three or four, species occur regularly, such as ) 0 North1 America (Du Bois 1935, 1936; Forbush 1927; Lovell 1944; Pickwell 1931), Europe 0 2 (Abs 1963; Guichard 1960; Harrison & Forster 1959; Hartley 1946; Koftln 1960; Labitte d e t 1958; Lebeurier & Rapine 1935; Wadewitz 1957) and Australia (Bourke 1947; Bravery 1962). a d In( Africa the biological information is largely confined to works of a general nature (Andersson r e 1872; Etchecopar & HUe 1964; Heim de Balsac & Mayaud 1962; Hoesch 1955; Macdonald h s i 1957;l McLachlan & Liversidge 1957; Meinertzhagen 1954; Smithers 1964; Valverde 1957), b althoughu a few more detailed studies do exist (Steyn 1964; Van Someren 1956; Winterbottom & P Wilsone 1959).
