Marine, Freshwater + Terrestrial Ecology

At Tonkin + Taylor, our consultants and scientists deliver a comprehensive suite of Ecology and Water Science services that advance sustainable development and safeguard natural resources. Our Ecology Consultants and Scientists are experts in terrestrial, freshwater, wetland, and marine ecosystems. We excel at applying science in regulatory contexts and are highly regarded in New Zealand, shaping guidance and policy. Many of our team members are industry authorities, with experience in Council and Environment Court hearings and as Certified Environmental Practitioners.
Our services encompass the full project lifecycle, from pre-purchase assessments and site investigations to environmental impact assessments for consents, management plans, construction support, and the design and delivery of habitat restoration and monitoring programs. Collaborating with geospatial and digital experts, we develop tailored data capture tools to enhance efficiency and accuracy. We guide clients in meeting environmental regulations and reducing environmental impact. Our team implements ecological management plans for construction projects, partnering with contractors to limit ecological effects.
