CES Environmental and Social Advisory Services RMLM Residential Development (Berg/Drooge Street) ii Ecological Impact Assessment Report AUTHOR AND SPECIALIST Mr Aidan Gouws, Environmental Consultant and Ecological Specialist Aidan obtained his MSc in Environmental Science (Cum laude) from Rhodes University, having conducted research on the spatio-temporal dynamics of Acacia dealbata invasions and broader land-use and cover changes in the northern Eastern Cape, funded through a study bursary awarded by the Agricultural Research Council (ARC). Prior to this, he obtained his BSc Honours in Geographical and Environmental Sciences (Cum laude) from the University of Pretoria, studying plant ecology and EIA methodology amongst others. He is also member of the Golden Key Honours Society. Aidan joined CES in 2018 and has been involved in several projects, including Basic Assessments, Full Scoping and Environmental Impact Assessments, Environmental Audits and Resettlement Action Plan (RAP) Audits. He works from the Johannesburg office and his interests include the general Environmental Impact Assessment (EIA) process, GIS mapping, ecological studies and the Public Participation Process (PPP). Ms Tarryn Martin, Principal Environmental Consultant and Report Review (Pri.Sci.Nat.) Tarryn holds a BSc (Botany and Zoology), a BSc (Hons) in African Vertebrate Biodiversity and an MSc with distinction in Botany from Rhodes University. Tarryn’s Master’s thesis examined the impact of fire on the recovery of C3 and C4 Panicoid and non-Panicoid grasses within the context of climate change for which she won the Junior Captain Scott-Medal (Plant Science) for producing the top MSc of 2010 from the South African Academy of Science and Art as well as an Award for Outstanding Academic Achievement in Range and Forage Science from the Grassland Society of Southern Africa. Tarryn specialises in conducting vegetation assessments including vegetation and sensitivity mapping to guide developments and thereby minimise their impacts on sensitive vegetation. She has conducted a number of vegetation and impact assessments in South Africa for renewable energy EIAs and assisted with the botanical baseline survey for the Lesotho Highlands Development Authority Polihali Dam. She has also conducted a number of vegetation surveys, to IFC standards, in Mozambique, has also worked on a Critical Habitat Assessment for Sasol in Inhambane Province and has co- designed and implemented the Terrestrial Monitoring Program for Kenmare, MOMA, a heavy minerals mine in Mozambique. Ms Amber Jackson, Principal Environmental Consultant and Report Review Amber is a Principal Environmental Consultant and has been employed with CES for the last 7 years. She has an MPhil in Environmental Management and has a background in both Social and Ecological work. Her undergraduate degrees focused on Ecology, Conservation and Environment with particular reference to landscape effects on Herpetofauna, while her masters focused on the environmental management of social and ecological systems. During her time at CES Amber has worked extensively in South Africa and Mozambique managing a number of Environmental and Social Impact Assessments. Amongst which she has conducted large scale faunal impact assessments in the both South Africa and northern of Mozambique to both national standards and international lenders standards (AfDB, EIB and IFC), alone and assisted by and to Prof Bill Branch.

Zeerust is located approximately 70km north-east of Mafikeng, 130km west of Rustenburg and 130km south south-east of Gaborone. The 12.65ha area will be subdivided into approximately 100 stands. Stands will be sold to prospective residents who will then construct their own housing. Adjacent municipal services, including water, electricity, waste removal and roads will be extended into the site. The proposed site is a green field’s site zoned for agriculture and comprised of degraded to near intact indigenous vegetation. The clearing of indigenous vegetation and transformation of open space into residential housing requires an environmental licence. The municipality will be responsible for the clearing and pegging of the site, as well as the extension of services. The project site and surrounding areas were described using a two-phased approach. Firstly, a desktop assessment of the site was conducted in terms of current vegetation classifications and biodiversity programmes and plans. Secondly, a site visit was conducted in summer on 18 and 19 February 2019 to assess the site-specific ecological state, current land-use, identify potential sensitive ecosystems and identify plant species associated with the proposed project activities. The site visit also served to identify potential impacts of the proposed development and its impact on the surrounding ecological environment. Using available spatial data it as determined that the project site falls within the Zeerust Thornveld vegetation type (Mucina and Rutherford, 2012) and within an area classified as an Ecological Support Area (ESA) 2, with a small portion falling within an area classified as a Critical Biodiversity Area (CBA) 1. The field survey confirmed that Zeerust Thornveld vegetation type occurs throughout the site and is considered to be moderately degraded, particularly near Drooge Street due to the edge effects from the road, i.e. people walking through the site, using the site for illegal dumping as well as for grazing livestock. This vegetation type ranges from being open thornveld throughout most of the site to a small patch of closed thornveld towards the south eastern portion of the site. The tree canopy ranges from 3-4m with emergent trees at about 5-6m. The understory is dominated by a grass layer interspersed with some herbs. Dominant tree and shrub species include Euclea spp., Searsia lancea, Senegalia caffra, Vachellia spp., Vangueria infausta, Tarchonanthus camphoratus, Grewia flava, Gardenia volkensii var. volkensii and Ziziphus mucronata. Low growing shrubs include Asparagus africanus, Asparagus cf. laricinus and Felicia filifolia, which are interspersed with herbs such as Lippia javanica, Aneilema aequinoctiale, Chascanum hederaceum, Cyanotis speciosa, Elionurus muticus, Hibiscus microcarpus, Lasiosiphon kraussianus, Oxalis obliquifolia, Polygala
