on the site to erosion and compaction. This will have a negative effect on the terrestrial ecosystems and wetlands in that siltation and habitat fragmentation could occur. Significance It should however be noted again that a large proportion of the site is currently cultivated and only a small percentage of natural habitat remains on site. The significance of this impact with mitigation measures is thus given as low. Mitigation: • Cordon off the sensitive vegetation (hydrophilic and primary grassland) to restrict the movement of construction vehicles and construction personnel. • Construction areas should be inspected for any occurrence of erosion. Appropriate remedial action (rehabilitation) must be undertaken should any eroded areas be identified. • Areas designated as sensitive should be incorporated into an open space system which must be managed in accordance with an Environmental Management Plan. • A comprehensive surface runoff and storm water management plan should be compiled, indicating how all surface runoff generated as a result of the development (during both the construction and operational phases) will be managed. • No development should take place within any area demarcated as sensitive. 13.3.3 Destruction of faunal habitat and faunal displacement Table 27: Destruction of natural habitat and displacement of species Activity Construction and operational activities Nature of the Destruction of faunal habitat faunal displacement Status - impact Receiving environment Magnitude Weighting factor (WF) Mitigation Efficiency (ME) Significance Significance With Mitigation (WM) EIA-REP-325d-11 October 2012 Usutu Site Extent (footprint; site; regional; national; international) SITE Intensity (low; medium; high) MEDIUM Duration (short; short-med; medium; long; permanent) PERMANENT Probability (Improbable; possible; likely; highly likely; definite) LIKELY WF (low; low-medium; medium; medium-high; high) LOW MEDIUM ME (high; medium-high; medium; low-medium; low) LOW MEDIUM Without mitigation (WOM) With mitigation (WM) LOW Source of the impact (Extent + Intensity + Duration + Probability) x Weighting Factor (2 + 3+ 5+ 3) x 2 = 26 Low to Medium WOM x ME = WM 26 x 0.4 = 10.4 Low 133
Destruction of faunal habitat and the displacement of species from their traditional home ranges during the construction phases of the proposed mining activity. Description of the impact Faunal species could be displaced during the construction phase. This could result in higher than normal social, grazing and browsing pressures on areas that would otherwise not have these impacts. This could result in degraded vegetation cover in areas that the life stock has moved to and a depauperation in the associated habitat i.e. from trampling, erosion, grazing or browsing and other forces. Significance The significance of the impact is expected to be of a medium significance without mitigation, this due to the displacement of faunal species from their habitats on site to allow for the building of the proposed development. With mitigation the significance of the impact will be reduced to that of a low significance. Mitigation • Minimising the loss of flora and fauna in areas that are not directly affected by the new development; • Reduce the levels of disturbance on the area during construction; • All construction areas should be suitably top soiled and vegetated as soon as is possible after construction; and • Disturbed surfaces to be rehabilitated must be ripped, and the area must be backfilled with topsoil or overburden. 13.3.4 Reduction of Natural Migratory Routes Table 28: Reduction of natural migratory routes and faunal dispersal routes Activity Construction and operational activities -Vegetation clearance and habitat destruction Nature of the Fragmented Landscape Status - impact Receiving environment Magnitude Weighting factor (WF) Mitigation Efficiency (ME) Significance Significance With Mitigation (WM) Source of impact: EIA-REP-325d-11 October 2012 Usutu Site Extent (footprint; site; regional; national; international) REGIONAL Intensity (low; medium; high) MEDIUM Duration (short; short-med; medium; long; permanent) LONG Probability (Improbable; possible; likely; highly likely; definite) LIKELY WF (low; low-medium; medium; medium-high; high) LOW MEDIUM ME (high; medium-high; medium; low-medium; low) LOW MEDIUM Without mitigation (WOM) With mitigation (WM) LOW (Extent + Intensity + Duration + Probability) x Weighting Factor (3 + 3+ 4+ 3) x 2 = 26 Low to Medium WOM x ME = WM 26 x 0.4 = 10.4 Low 134
