Services GoldSET - Socio-Ecological Mitigation


Golder was engaged to assist in determining the optimal biodiversity offset for the Strongman Mine. To do so, Golder developed a socio-ecological mitigation evaluation module for GoldSET, developing specific indicators for assessing the ecological values, social acceptance and economic implications of the offset options, in order to identify the most sustainable and optimum biodiversity offset option.

Our Role

Golder’s role was to undertake a high-level multicriteria evaluation of three potential offset sites within the North Westland Ecological Region of New Zealand. Indicators evaluated the offset sites in terms of themes related to either the ecological, social or economic dimensions of analysis including: ecological equivalency, ecological and conservation context, risk of offset failure, time/space performance, public use and business generation opportunities, land tenure, cultural heritage, capital and operational costs, and finally the legal and planning costs of establishing and operating the offset. Golder, with the assistance of SENZ and stakeholders, scored and weighted each indicator for the performance of each offset option to present the best offset option.
