8 OGNZ WUG mine: assessment of potential ecological effects Project 2034 Controls: Pest animal trapping and control over wider surface activities area. Increased human presence/ foot disturbance (short-term, then much reduced during longer-term maintenance phase) Human activities during construction and maintenance may disturb or kill frogs. Potential for disease introduction. Controls: Requirements to stay to set tracks/ paths/ within fenced areas. Boot and equipment wash stations. Negligible Very Low over a wide area Resource consent, which will be sought for exploration drilling for vent shafts. Short-distance relocation shortterm) Effects of moving animals into adjacent habitat and/ or homing abilities of frogs could potentially impact frog health/ survival. This could only occur where approved sites yield frogs during clearance (very low number of individuals that could be affected). Controls: nil, although could require provision of additional habitat (logs, ground covers, cover objects). Low Very Low over very few occurrences Either already approved under existing WAA from DOC, and or will be applied for new sites.
