Boffa Miskell Ltd | Waihi North Project | Terrestrial Ecology Values and Effects of the WUG | 22 June 2022 89 Pest management to offset potential loss of Archey’s frogs Pest Influx Effects on Fauna During Vent Construction Local pest control around vent shaft sites, camp sites Wasp control to reduce competition, predation and disturbance caused by wasps Vibration from underground blasting Variable mining methods to minimise vibration related impacts on the surface and potential disturbance to fauna above the WUG. Offset / compensation pest animal control over an area of 633 ha to benefit Archey’s frogs (and other fauna groups) where potential residual risks have been identified (see Section 8.5.3) Spread of Kauri Dieback Disease Baseline disease testing in waterways and soil to assess presence of PA prior to works Biosecurity hygiene procedures. These procedures will be described in the Coromandel Forest Park Kauri Dieback Management Plan (CFP KDMP) CFP Ecological Benefit Replanting and facilitating natural regeneration of an approximate 55,000 m2 on the forest boundary on Willows Road Farm to return the forest to its previous extent. 9.0 Summary and Conclusion The WUG Project Area comprises two discrete areas, Willows Road Farm and Coromandel Forest Park. The Project Area is entirely contained within the Waihi Ecological District. Willows Road Farm is located approximately 5 km north of Waihi township and adjoins Coromandel Forest Park on its northern and north-western boundaries. The property is currently in use as a low intensity cattle / dairy farm. Vegetation cover is dominated by pasture with narrow and patchy riparian remnants and some single standing trees in pasture. Several larger native bush fragments are present outside of the project footprint. The primary effect associated with Willows Road Farm activities is the loss of low value vegetation and potential fauna habitats within the project footprint. As part of the integrated mitigation strategy, OGNZL propose to revegetate approximately 56,600 m2 of the available riparian areas for ecological and landscape mitigation purposes, including to offset effects of vegetation removal there. These are described in the Freshwater and Wetland Ecological Assessment. The remaining effects (construction noise and discharges to air) will be minimised through engineering design and site management processes. The level of effects with management on Willows Road Farm range from Low to Very Low.
