Appendix 3: Vegetation Descriptions for Willows Road Farm and Potential Vent Raise Sites Boffa Miskell Ltd | Waihi North Project | Terrestrial Ecology Values and Effects of the WUG Other survey information: Two nights of Archey’s frog surveys were completed at Site 3 (Table 3). Weather conditions were ideal for frog emergence (>13 C° and >80% relative humidity), with no individuals found. No additional surveys were completed at this site due to the topography causing difficulty for platform building. Table 3: Survey details from Archey’s frog searches at Site 3 Date Survey Effort (hrs) Average Temperature (C°) Average Relative Humidity (RH) % Number of frogs found 31/03/2021 3 18 95.6 0 31/03/2021 3 16.3 98.2 0 Suitability for vent site: The topography of the site is unsuitable for a drill platform. Site 4 Site 4 is located on the border of Site 3 and just outside the paper road. The site is dominated by nikau, with an upper canopy of <12 m. The ground has a thin layer of leaf litter and was heavily pig rooted during frog surveys. The occasional seedling and sapling of hangehange, mapou, rewarewa, and kanono can be found. A large tōwai (<40 cm DBH) is located just outside the site. Vegetation within the site is not suitable frog, bat, or lizard habitat. No ‘Threatened / At Risk’ plant species were identified. Other survey information: One survey was completed for Archey’s frogs during suitable weather conditions (>13 C° and >80% relative humidity) (Table 4). No ‘Threatened / At Risk’ invertebrate species were identified during frog surveys.
