Info

The manual searches undertaken and the 40 artificial refuges deployed in a range of potential habitat areas to survey for lizards established the presence of a solitary common skink, Oligosoma polychroma, just outside the upper margins of the proposed clean fill extent. This species is not threatened according to Hitchmough et al 2010. However, we note that the lizard survey was of limited duration and did not extend to spotlighting for gecko species. There was evidence of cattle, sheep, goat browsing and pig rooting within and upstream of the application site in the main gully system. Ongoing possum control was evidenced by a number of recently baited Timm’s Traps surrounding the site and control of possums will have contributed to the high diversity within the kanuka and broadleaf forest in the upper gully system. 3.5 Landform and soils In terms of landform and soils at the study area, the LUC classification is 6e6, which indicates the study area is moderately steep, to steep (21° – 35°) inland greywacke hill country in areas of moderate rainfall (1,140-1,270 mm p.a.) with seasonal soil moisture deficiencies. Soils are Makara steepland soils and Korokoro Hill soils formed from shallow patchy loess over slightly weathered greywacke and related slope deposits. Based on the LUC database, erosion for this LUC area is negligible but with the potential for moderate soil slip, scree and sheet erosion where forest cover is removed. Pastures are prone to scrub reversion and maintenance of a complete vegetation cover is necessary. Dry Creek Replacement Cleanfill, SH 58, Porirua | Assessment of Terrestrial Ecological Effects 10
