The effect of vegetation removal on indigenous fauna arising from the loss of those habitats has
been considered as no more than minor due to the similarity of nearby habitats and wide ecological
tolerances and adaptability of the affected indigenous bird species. However the protection of
lizards in the project area has been identified as having particular importance.
Project-Specific Issues and Requirements
Freshwater - There is the potential for long term positive effects to be realised through riparian
enhancement of realigned and other existing water races within the project area and improved
water quality through stormwater treatment. In addition, culverts will be designed to ensure the
provision of fish passage or where the proposal involves long sections of piping, fish screens will be
included to prevent entry and stranding of fish. In addition management of sediment (SEMP 002)
and landscaping (SEMP 005) will assist in maintaining and enhancing the aquatic environment.
Terrestrial - The Project presents an opportunity to enhance the ecological value of the affected and
surrounding land, which is highly modified and contains little in the way of naturally occurring
indigenous vegetation. The proposed landscape measures will also mitigate the adverse effects of
the Project resulting from habitat loss and disturbance.
Extensive landscape mitigation measures are proposed as part of the Project. These incorporate a
large component of totara/matai forest and shrubland plantings that in combination with mixed
indigenous/exotic woodland plantings this will significantly enhance ecological values within a
highly modified landscape. Low plantings of appropriate species proposed along sections of stock
water races will improve the habitat value of the riparian margins and their connectivity at a
landscape scale. A GCS concerning Terrestrial Ecological Protection is recommended to be
developed that sets out an approach to manage terrestrial features such as existing vegetation that
is to remain within the Project area from any construction activities undertaken. The procedure shall
also include an approach to minimise introduction and colonisation of pest species.
The landscaping also provides the ability to accommodate boulder fields and boulder strips that can
include appropriate planting to mitigate against any habitat loss as a result of the development. The
incorporation of boulder fields will be confirmed upon the outcome of the lizard survey which is
currently being undertaken.
CEMP Expectations for the appointed Principal Contractor
The SEMPs for Erosion & Sediment Control (SEMP 002 within Appendix B of this CEMP) and the
Landscape Management Plan (SEMP 005 within Appendix E of this CEMP), should be followed and
where necessary be reviewed and updated once a detailed construction programme and build
methodology has been agreed with the NZTA by the Principal Contractor and the Construction
Environmental Manager. A General Control Statement for Terrestrial Ecological Protection should
also be developed.
