Mike Demarchi has expertise in many aspects of marine and terrestrial ecological research and impact assessment from study design through final reporting and post‑construction monitoring under provincial and federal assessment processes. He is at home in both marine and terrestrial ecosystems and has served as a senior project biologist on a number of high‑profile projects for clients at all levels of government, First Nations, Crown corporations, military, small private firms, and multi-national companies. His work involves metal and coal mines, quarries, airports, hydroelectric dams and reservoirs, geothermal energy, transmission lines, marine and terrestrial seismic surveys, rapid transit, highways, gas and oil pipelines, offshore wind power, and marine port and terminal facilities.
