Simon Todd Pr.Sci.Nat 400425/11. 4 Terrestrial Fauna and Botanical Specialist Study for Basic Assessment THEMBALETHU UISP – Bulk Services & Area 8A/B EXECUTIVE SUMMARY This report details the impacts of the development of bulk sewer infrastructure, as well as the housing on Area 8a&b, at Thembalethu near George in the Western Cape on the fauna and flora of the area as part of the Basic Assessment process required for the development. A three-day site visit and associated desktop review of the available ecological information was conducted to assess the presence and distribution of ecologically sensitive, species and habitats at the site. An ecological sensitivity map for the site was generated which is depicted below. The field assessment reveals that the site is largely highly degraded as a result of alien plant invasion, previous transformation and high levels of anthropogenic impact. Areas where the vegetation can be considered to be in a natural to near-natural condition are limited in extent. Ecological Sensitivity Map: The intact areas include fynbos and Afrotemperate Forest patches. Although these areas are considered sensitive and retain significant biodiversity, the long- term viability and persistence of these areas is uncertain due to the high alien plant invasion pressure as well as anthropogenic impacts such as hunting, livestock grazing and collection of plants for traditional medicine. The most sensitive area identified during
